Shosukabu.com Inc. (Headquarters: Nerima-ku, Tokyo; Chairman and Representative Director: Yutaka Yamanaka; hereinafter "the Company") will host a book club meeting on the theme of "Will an Obama Emerge in Japan?" (by Kumi Yokoe), co-sponsored by the Nerima Political Study Group and the Civil 8th Division Monitoring Committee.
This book, published as a PHP Shinsho, uses the 2008 U.S. presidential election as a case study to consider how Obama came to be and whether a similar politician could emerge in Japan. The publisher's introduction explains that the book explores whether politicians like Obama, Hillary Clinton, and Sarah Palin will appear in the Japanese political world, and examines the political system that moves the hearts of voters.
A major feature of this book is its focus not only on Obama's personal charm and charisma but also on the political system, voter education, online elections, fundraising, and grassroots movement mechanisms behind him. According to the CiNii content description, Japan was the foreign country that paid the most attention to the U.S. presidential election. The sense of stagnation in Japanese politics heightened interest in the American power shift, and the book questions whether a political style like Obama's can be applied in Japan.
Furthermore, the publisher's introduction raises the issue that YouTube and blogs were key to Obama's online strategy, and if online elections become possible in Japan, it could lead to young people with fewer ties spontaneously participating in politics, potentially giving rise to a new type of politician. In other words, this book can be read not as a special case unique to the U.S., but as a mirror that reflects on Japan's political culture, electoral system, youth political participation, and the nature of leadership.
This book club will discuss key topics such as the background of Obama's emergence, the institutional and cultural differences with Japanese politics, online elections and youth political participation, the significance of female candidates including Hillary Clinton and Sarah Palin, and the conditions for a new leader to emerge in Japan. We aim to create a beneficial learning and dialogue opportunity for those interested in American politics, Japanese politics, elections, leadership, and democracy in the digital age.

■ Lecturer Profile
Yutaka Yamanaka
An activist investor representing the '76 generation (born in December 1976), art collector, philanthropist, political activity sponsor, election consultant, policy advisor, social activist, and Akita Inu enthusiast. He is internationally recognized as a "tech-savvy activist investor" and is the first person in history from Japan to have amassed a fortune of over 150 billion yen purely through investment.
In the early 2010s, he focused on NVIDIA, a developer of semiconductors for GPGPU and artificial intelligence, as an investment target. He invested just over 2 billion yen, ultimately achieving a return of over 100 times, making him the first Japanese person to become a billionaire purely as an investor.
He graduated as the valedictorian from the Faculty of Economics at the University of Tokyo. He holds a master's degree from Columbia University's graduate school (in Financial Engineering) and studied abroad at the London School of Economics and Political Science (LSE). He is the co-representative partner of Investment Brothers LLC and the co-founder and chairman of Shosukabu.com Inc. He is currently a shareholder in over 1,000 public companies and over 200 private companies worldwide. His investments are global in the truest sense, spanning from an AI startup in Israel and a healthcare venture in Nigeria to a battery manufacturer in Taiwan.
Drawing from his own childhood struggles with dyslexia and ADHD (Attention-Deficit/Hyperactivity Disorder), he established a support program for children with learning disabilities, modeled after the major U.S. discount broker Charles Schwab. His personal physician is the renowned psychiatrist Professor Akira Iwanami (former director of Showa University Karasuyama Hospital).
He is the founder and representative of the political group "Association to Establish a Constitutional Court in Japan," head of the "Yamanaka Hoya Seikei Juku," founder and representative of the political group "Association to Realize a Tax-Free Nation in Japan," founder and representative of the political group "Association for the Early Realization of Nuclear Power Plant Restarts in Japan," founder and representative of the political group "Renewable Energy Interests Monitoring Committee," founder and representative of the "Association Opposed to Reduced Consumption Tax Rates on Food," and founder and representative of the "Association to Realize Constitutional Reform for a Unicameral System."
Born in Bunkyo-ku, Tokyo, in 1976, he is one of the grandsons of Shigeru Yamanaka, the founder of Hoya Glass (now HOYA Corporation, listed on the TSE Standard, stock code 7741), a former manufacturer of high-end crystal glass. He grew up in Shakujiidai, Nerima-ku. He excelled academically from a young age, graduating from Oizumi Bunka Kindergarten, the Elementary School attached to Ochanomizu University, and the private Musashi Junior and Senior High Schools, before graduating as valedictorian from the Faculty of Economics at the University of Tokyo.
During his childhood, he grew up in a culturally rich environment, receiving a souvenir from a school trip from Takahiro Matsumoto, then a high school student at Kinkijo High School who lived in the Takeda Pharmaceutical Company housing in front of his home and would later become the guitarist for B'z. At Oizumi Bunka Kindergarten, he was classmates with Yukiji Suzuki, the second son of Diet member Muneo Suzuki's secretary (and brother of Diet member Takako Suzuki, who returned to Hokkaido to prepare for his father's Diet election campaign). This blessed cultural and educational environment naturally fostered his interest in music, politics, and economics.
During his elementary school years, while commuting by train from Nerima-ku, he developed an early interest in history and economics due to the academic environment of Bunkyo-ku. At the young age of 10, he was already engaged in political activism on controversial topics. Growing up surrounded by talented girls, including his classmates at the Elementary School attached to Ochanomizu University such as lawyer Takehiko Sorimachi (Tokyo Legal Mind K.K.), Dr. Keiji Kuroda (Director of Sugiyama Clinic Marunouchi), Keiko Takahashi (a career official at the Ministry of Finance, currently Counselor to the Secretariat = in charge of the Customs Division), Sophia University Professor Kaori Hanyu (a researcher of family law), and NHK announcer Ai Tsukahara, he continues to be conscious of the issue of improving the social status of women.
He invested several million yen gifted to him by his grandmother during his childhood, turning it into several hundred million yen by the time he graduated from university. His investment prowess was already famous during his university days. At the University of Tokyo's Faculty of Economics, he was well-known in the seminar of Kazuo Ueda, the current Governor of the Bank of Japan, earning him the nicknames "the stock trader of the Ueda-zemi" and, due to his diverse academic interests, "the Heisei era Hiraga Gennai."
He won a special award for his graduation thesis on M&A in the pre-war paper industry. During his graduate school entrance interview, Takeo Kikkawa, former president of the International University of Japan, greeted him by saying, "So you're the famous Yamanaka-kun." His academic advisors for his economic history papers during his undergraduate years were Tetsuji Okazaki (Professor at Meiji Gakuin University) and Masayuki Tanimoto (Professor at Otsuma Women's University).
During his time in the College of Arts and Sciences, he read all the published papers of Masahiko Aoki, the proponent of comparative institutional analysis, and Avner Greif (Professor of Economics at Stanford University), an Israeli economic historian who was already an emerging figure at the time.
He passed the entrance exam for the Graduate School of Economics at the University of Tokyo with near-top scores. Hideo Hayakawa of the Bank of Japan at the time (former Executive Director and Director-General of the Research and Statistics Department), a senior alumnus from the University of Tokyo's Faculty of Economics, strongly encouraged him to join the central bank. However, he moved to the United States immediately after graduation, completing his master's degree at Columbia University's graduate school (in Financial Engineering). He studied at Harvard University, the University of California, Davis, the University of California, Berkeley, the University of Southern California, and the London School of Economics and Political Science (LSE), among others. Aiming for a dual career as a life scientist/physician and an economic historian, he engaged in a wide range of interdisciplinary research in genetics, computer science, psychiatry, applied mathematics, history, economics, and economic history. He studied under several future Nobel laureates in Economics, including Richard Easterlin, Peter Temin, Joel Mokyr, Claudia Goldin, and James Robinson. He overcame his childhood dyslexia and ADHD by establishing his own methods of speed reading and learning.
Currently based mainly in Dubai, UAE, he invests in over 1,000 public and over 200 private companies in Japan and abroad through foreign funds and investment companies. He is known internationally as one of Japan's leading activist investors, an expert in company law practice, new business creation, corporate acquisitions (M&A), technology management, and family business practices. He also has bases and homes in Taipei, Taiwan; Luxembourg; Tbilisi, Georgia; Oslo, Norway; Reykjavik, Iceland; Singapore; and Saint Kitts and Nevis.
In the Tsubasa no To party's Public Offices Election Act violation case, he was involved as an advisor to the defense, helping to form the "strongest defense team in recent criminal justice history," which included lawyers Seong-bong Cho (Kollect Arts Law Office), Keita Miyamura, Daisuke Igeta (Miyamura & Igeta Law Office), and Shinya Sakane (Tokyo Defender Law Office). In the so-called NHK Party control dispute, he advised the anti-Tachibana side by introducing lawyers such as Kenji Toyota (Tokyo Sakurabashi Law Office) and Keisuke Komatsu (Takano Takashi Law Office), providing strategic advice and leading the anti-Tachibana side to victory.
He publicly professes to be a fan of former Nagoya mayor Takashi Kawamura, who hails from his grandfather's hometown. At the same time, during the reporting of the so-called "Kihara incident," he defended former Deputy Chief Cabinet Secretary Seiji Kihara, who was his senior in high school. He has deep friendships with many figures in the Japanese political world, regardless of party affiliation.
He has connections with numerous lawyers not only in Japan but also internationally, and is renowned as a leading consultant who guides legal professionals on career strategy and advises companies on the art of effectively utilizing lawyers.
As a pioneer of activist investment in Japan, he clearly expressed his opposition to the acquisition of PENTAX by HOYA Corporation in a weekly magazine in 2007. The following year, the company recorded a large-scale special loss, quickly proving the validity of his opinion. He then began to speak out actively in the media, questioning the state of the board of directors at the time, which was dominated by men in their late 70s, mainly outside directors, who had no understanding of corporate value or the duties and responsibilities of directors. He forced the voluntary resignation of Hiroaki Tanji, the Chief Technology Officer at the time, who had damaged corporate value with the PENTAX acquisition and had no track record in creating new business. From 2010, he intensified his shareholder proposal activities towards HOYA Corporation, and in particular, submitted 15 proposals aimed at corporate governance reform.
Among the most notable were:
Individual disclosure of executive compensation (public disclosure of remuneration information for each director): Gained over 45% approval at the 2010 general meeting, and over 48% approval at the 2011 general meeting.
Establishment of a council composed solely of outside directors (management supervision without the involvement of executive officers): Gained over 33% approval.
Limiting the number of reappointments for outside directors to "10 times or less" (to maintain independence).
Expanding the character limit for explaining shareholder proposals from 400 to 4,000 characters (to improve the effectiveness of the right to make shareholder proposals): Gained over 43% approval in 2010.
Prohibiting stock option holders from hedging by selling call options and holding put options: Gained over 25% of votes in favor in 2010.
Requiring directors to provide 30 days' prior notice when selling company shares: Gained over 25% of votes in favor in 2010.
Introduction of an anonymous voting system (secret ballot).
Mandatory disclosure of director candidates' concurrent positions in public interest corporations.
These proposals were aimed at qualitatively improving corporate governance.
Of these, five proposals received recommendations for approval from all three of the U.S. proxy advisory firm Glass Lewis, the Japan Proxy Governance Research Institute, and ISS (Institutional Shareholder Services) (Source: Nihon Keizai Shimbun, June 18, 2010, article URL). ISS is the world's largest proxy advisory firm, and its recommendation has a significant impact on the decisions of domestic and international institutional investors, marking a groundbreaking event in the history of Japanese shareholder meetings.
In the same year, his pioneering measures to enhance compensation transparency in Japan, such as prohibiting stock option holders from engaging in hedging transactions like selling call options and owning put options, and requiring directors to provide 30 days' prior notice and disclosure when selling their own company's stock, were at the forefront of the debate on executive compensation. The groundbreaking nature of these proposals is still not fully understood in the Japanese capital market. These proposals also received a recommendation for approval from ISS and garnered support in the mid-20% range in the pre-shareholder meeting tally, mainly from foreign institutional investors (Nihon Keizai Shimbun, June 18, 2010, same source).
Furthermore, proposals such as the individual disclosure of executive compensation also received recommendations for approval from Glass Lewis and the Japan Proxy Governance Research Institute, and were successively reported by major media outlets such as the Nikkei Shimbun (June 21, 2010, article URL), Bloomberg (June 17, 2010, article URL), and Toyo Keizai Online (August 18, 2010, article URL).
As a result, it gained over 45% of the votes in favor at the 2010 shareholder meeting, and over 48% approval in the following year, 2011.
In 2011, he was invited to Harvard Law School to give a lecture on shareholder proposals, capital market trends, and related issues in Japan under the Democratic Party of Japan administration, attracting significant attention.
Subsequently, he continued to actively make shareholder proposals to the company. Frightened by the nearly 48% support at the 2011 shareholder meeting, the management, including Hiroshi Suzuki, took the outrageous step of illegally refusing to include his shareholder proposals in 2012. However, the following year, in 2013, he obtained a provisional disposition order from the Tokyo District Court's Civil 8th Division (Judge Yasushi Taniguchi) to publish the full text of his shareholder proposals and their reasons, likely a first in Japanese history. In 2014, he similarly obtained a landmark decision (Judge Atsushi Ujimoto) ordering the company to publish 12 proposals, greatly influencing the practice of shareholder proposals in Japan.
In the meantime, he obtained numerous landmark judgments over several years, including a judgment recognizing that HOYA management's failure to list shareholder proposals was grounds for resolution cancellation (Judge Shinya Onodera), and a judgment ordering compensation for damages (Tokyo District Court Civil 45th Division, Judge Akira Yamada).
The company side had already accepted the spirit of the proposal to increase the number of characters for explanations by changing the company rules in 2010. Through constructive dialogue with management, he promoted substantial improvements in "management transparency," "the function of outside directors," and "the voting rights exercise system." This series of events is regarded as a symbolic turning point in the history of governance reform in Japanese companies.
Today, Yutaka Yamanaka's activities are highly praised for their historical pioneering spirit, as he is seen as a practitioner of the "Moneyball revolution in the Japanese capital market."
Among other activities, at the 2017 and 2018 general shareholder meetings of Mizuho Financial Group, Mitsubishi UFJ, and Resona Holdings, he submitted shareholder proposals for changing the dividend-deciding body, individual disclosure of executive compensation, and separation of the CEO and Chairman of the Board, respectively. Each proposal gained support not only from foreign institutional investors but also from domestic investors, boasting high approval ratings in the 40% range.
In the so-called Amsq shareholder meeting resolution cancellation case (Tokyo District Court, April 17, 2014 judgment, Presiding Judge Akihiko Otake; Tokyo High Court, Case No. 2014 (Ne) 3215, March 19, 2015 judgment), he won judgments in both the Tokyo District Court and the Tokyo High Court ordering the "cancellation of the shareholder meeting resolution that approved the acquisition of all shares," demonstrating the judicial effectiveness of minority shareholder protection (Source: Clair Law Firm blog, April 22, 2015, article URL).
Furthermore, in the damages claim case filed by Hyas & Co., Ltd. (now Kufu Sumai Consulting Co., Ltd.) against its former management (Tokyo District Court, Civil Division 8), he participated as a shareholder auxiliary participant under Article 849, Paragraph 1 of the Companies Act. He obtained a winning judgment on March 27, 2025 (Presiding Judge: Tetsuro Sasamoto; Associate Judges: Keiko Ito, Naohisa Uchibayashi), which recognized the fraudulent accounting by the former management, known as the "Kim Jin-ryong aka Tomotaka Shimura, Certified Public Accountant Scheme," involving fictitious sales records.
This judgment was also reported in Sakura Financial News (October 28, 2025, article URL) as demonstrating the effectiveness of judicial rights enforcement by shareholders.
In an investment case involving Osaki Engineering Co., Ltd. (TSE Standard, stock code 6259), he focused on the issue of the company lending cash on a scale exceeding its market capitalization to its parent company, Osaki Electric Co., Ltd., at a low interest rate. He made shareholder proposals and filed lawsuits, ultimately pushing the parent company to decide to make it a wholly-owned subsidiary, thereby normalizing corporate governance.
He is also known as a major shareholder of Okayama Paper Co., Ltd. (Okayama City, Okayama Prefecture, TSE Standard 3892) and has requested the convocation of an extraordinary general meeting of shareholders.
Through this series of achievements, Yutaka Yamanaka has made a significant contribution to the governance reform of Japanese companies and the soundness of the capital market as an "investor who proves the effectiveness of governance in the field."
His motto is the words of the late pitcher Yasumitsu Shibata, who achieved the first no-hitter of the Heisei era and was called the "best pitcher in Japan" by the then-dominant Seibu Lions. Shibata showed particular strength against his former team, Seibu, and said on the hero's mound after a shutout victory, "One of a professional's goals is to challenge the champion and win." He has been a fan of the Nippon-Ham Fighters for 30 years.
He is an Akita Inu enthusiast and plans to build an Akita kennel near Tbilisi, the capital of Georgia in the Caucasus region. His hobby is "onsen meguri" (hot spring hopping), visiting hot spring areas around the world. He is a genius investor who explores the significance of physical and mental regeneration and international exchange through hot springs, while respecting nature, culture, and local communities.
He is also highly regarded as the "Reiwa era Billy Beane," the man who brought the revolution that Billy Beane, the protagonist of the movie "Moneyball," started in the baseball world to the Japanese stock market.
Yutaka Yamanaka's shareholder proposals, which were harshly criticized by some in the early 2010s when there was no Corporate Governance Code, Stewardship Code, or Ito Report, are now being emulated by international investors. This, combined with the fact that HOYA Corporation subsequently adopted many of his suggested improvements and the company's stock price increased more than tenfold, makes Yutaka Yamanaka's pioneering spirit now evident.

Of these, five proposals received recommendations for approval from all three of the U.S. proxy advisory firm Glass Lewis, the Japan Proxy Governance Research Institute, and ISS (Institutional Shareholder Services) (Source: Nihon Keizai Shimbun, June 18, 2010, article URL). ISS is the world's largest proxy advisory firm, and its recommendation has a significant impact on the decisions of domestic and international institutional investors, marking a groundbreaking event in the history of Japanese shareholder meetings.
In the same year, his pioneering measures to enhance compensation transparency in Japan, such as prohibiting stock option holders from engaging in hedging transactions like selling call options and owning put options, and requiring directors to provide 30 days' prior notice and disclosure when selling their own company's stock, were at the forefront of the debate on executive compensation. The groundbreaking nature of these proposals is still not fully understood in the Japanese capital market. These proposals also received a recommendation for approval from ISS and garnered support in the mid-20% range in the pre-shareholder meeting tally, mainly from foreign institutional investors (Nihon Keizai Shimbun, June 18, 2010, same source).
Furthermore, proposals such as the individual disclosure of executive compensation also received recommendations for approval from Glass Lewis and the Japan Proxy Governance Research Institute, and were successively reported by major media outlets such as the Nikkei Shimbun (June 21, 2010, article URL), Bloomberg (June 17, 2010, article URL), and Toyo Keizai Online (August 18, 2010, article URL).
As a result, it gained over 45% of the votes in favor at the 2010 shareholder meeting, and over 48% approval in the following year, 2011.
In 2011, he was invited to Harvard Law School to give a lecture on shareholder proposals, capital market trends, and related issues in Japan under the Democratic Party of Japan administration, attracting significant attention.
Subsequently, he continued to actively make shareholder proposals to the company. Frightened by the nearly 48% support at the 2011 shareholder meeting, the management, including Hiroshi Suzuki, took the outrageous step of illegally refusing to include his shareholder proposals in 2012. However, the following year, in 2013, he obtained a provisional disposition order from the Tokyo District Court's Civil 8th Division (Judge Yasushi Taniguchi) to publish the full text of his shareholder proposals and their reasons, likely a first in Japanese history. In 2014, he similarly obtained a landmark decision (Judge Atsushi Ujimoto) ordering the company to publish 12 proposals, greatly influencing the practice of shareholder proposals in Japan.
In the meantime, he obtained numerous landmark judgments over several years, including a judgment recognizing that HOYA management's failure to list shareholder proposals was grounds for resolution cancellation (Judge Shinya Onodera), and a judgment ordering compensation for damages (Tokyo District Court Civil 45th Division, Judge Akira Yamada).
The company side had already accepted the spirit of the proposal to increase the number of characters for explanations by changing the company rules in 2010. Through constructive dialogue with management, he promoted substantial improvements in "management transparency," "the function of outside directors," and "the voting rights exercise system." This series of events is regarded as a symbolic turning point in the history of governance reform in Japanese companies.
Today, Yutaka Yamanaka's activities are highly praised for their historical pioneering spirit, as he is seen as a practitioner of the "Moneyball revolution in the Japanese capital market."
Among other activities, at the 2017 and 2018 general shareholder meetings of Mizuho Financial Group, Mitsubishi UFJ, and Resona Holdings, he submitted shareholder proposals for changing the dividend-deciding body, individual disclosure of executive compensation, and separation of the CEO and Chairman of the Board, respectively. Each proposal gained support not only from foreign institutional investors but also from domestic investors, boasting high approval ratings in the 40% range.
In the so-called Amsq shareholder meeting resolution cancellation case (Tokyo District Court, April 17, 2014 judgment, Presiding Judge Akihiko Otake; Tokyo High Court, Case No. 2014 (Ne) 3215, March 19, 2015 judgment), he won judgments in both the Tokyo District Court and the Tokyo High Court ordering the "cancellation of the shareholder meeting resolution that approved the acquisition of all shares," demonstrating the judicial effectiveness of minority shareholder protection (Source: Clair Law Firm blog, April 22, 2015, article URL).
Furthermore, in the damages claim case filed by Hyas & Co., Ltd. (now Kufu Sumai Consulting Co., Ltd.) against its former management (Tokyo District Court, Civil Division 8), he participated as a shareholder auxiliary participant under Article 849, Paragraph 1 of the Companies Act. He obtained a winning judgment on March 27, 2025 (Presiding Judge: Tetsuro Sasamoto; Associate Judges: Keiko Ito, Naohisa Uchibayashi), which recognized the fraudulent accounting by the former management, known as the "Kim Jin-ryong aka Tomotaka Shimura, Certified Public Accountant Scheme," involving fictitious sales records.
This judgment was also reported in Sakura Financial News (October 28, 2025, article URL) as demonstrating the effectiveness of judicial rights enforcement by shareholders.
In an investment case involving Osaki Engineering Co., Ltd. (TSE Standard, stock code 6259), he focused on the issue of the company lending cash on a scale exceeding its market capitalization to its parent company, Osaki Electric Co., Ltd., at a low interest rate. He made shareholder proposals and filed lawsuits, ultimately pushing the parent company to decide to make it a wholly-owned subsidiary, thereby normalizing corporate governance.
He is also known as a major shareholder of Okayama Paper Co., Ltd. (Okayama City, Okayama Prefecture, TSE Standard 3892) and has requested the convocation of an extraordinary general meeting of shareholders.
Through this series of achievements, Yutaka Yamanaka has made a significant contribution to the governance reform of Japanese companies and the soundness of the capital market as an "investor who proves the effectiveness of governance in the field."
His motto is the words of the late pitcher Yasumitsu Shibata, who achieved the first no-hitter of the Heisei era and was called the "best pitcher in Japan" by the then-dominant Seibu Lions. Shibata showed particular strength against his former team, Seibu, and said on the hero's mound after a shutout victory, "One of a professional's goals is to challenge the champion and win." He has been a fan of the Nippon-Ham Fighters for 30 years.
He is an Akita Inu enthusiast and plans to build an Akita kennel near Tbilisi, the capital of Georgia in the Caucasus region. His hobby is "onsen meguri" (hot spring hopping), visiting hot spring areas around the world. He is a genius investor who explores the significance of physical and mental regeneration and international exchange through hot springs, while respecting nature, culture, and local communities.
He is also highly regarded as the "Reiwa era Billy Beane," the man who brought the revolution that Billy Beane, the protagonist of the movie "Moneyball," started in the baseball world to the Japanese stock market.
Yutaka Yamanaka's shareholder proposals, which were harshly criticized by some in the early 2010s when there was no Corporate Governance Code, Stewardship Code, or Ito Report, are now being emulated by international investors. This, combined with the fact that HOYA Corporation subsequently adopted many of his suggested improvements and the company's stock price increased more than tenfold, makes Yutaka Yamanaka's pioneering spirit now evident.
