"Gemini: The Ultimate AI Work Techniques" Goes into its 5th Reprint in 4.5 Months, Exceeding 23,000 Copies in Total Circulation

Geijutsu Shinbun Sha Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Sota Aizawa) is pleased to announce that "Gemini: The Ultimate AI Work Techniques" by Tomohiro Ikeda has gone into its 5th reprint in four and a half months since its release, surpassing a cumulative total of 23,000 copies in circulation. The book has garnered support from many business professionals, achieving the No. 1 spot for nine consecutive weeks on Maruzen Marunouchi Main Store's computer book ranking (October 20, 2025 - December 21, 2025).

With the growing interest in generative AI, "Gemini," developed by Google, is increasing its presence in the business scene. Amidst this trend, the needs of business professionals are rising, with demands such as "I want to utilize it more in my work" and "I want to know how to combine it with other Google services."

This book, under the banner "For Business Applications, Gemini is the Only Choice," is a practical introductory guide that meets such demands. Its distinguishing feature is its clear explanation from the perspective of how to master its use in actual work, rather than merely introducing Gemini's functions.

Furthermore, a unique appeal of this book is its in-depth exploration of how to specifically enhance work productivity, not only by explaining how to use Gemini alone but also by including its integration with Google Workspace and NotebookLM.

The content broadly covers themes directly related to daily work, such as idea generation, information gathering/research, document and material creation, foreign language translation, IT tool utilization, and "vibe coding" (likely referring to rapid prototyping or exploratory coding). It is a book that allows readers to experience Gemini utilization that "changes results," made possible through Google integration.

In addition to Maruzen Marunouchi Main Store, the book has also ranked No. 1 on the Kinokuniya Bookstore Shinjuku Main Store's computer book floor weekly ranking (as of February 16, 2026) and No. 1 on the Book 1st Shinjuku Store's PC book ranking (as of November 11, 2025), among other stores, achieving best-seller status. It has received particular support from major bookstores located in business districts.

Amazon customer reviews have included the following feedback:

"It's a practical reference book with an abundance of helpful prompts."

"I use Gemini regularly, but I found it helpful to learn about new ways to use it."

"It doesn't just explain how to use it; it focuses on specific practical application scenarios."

It is highly praised for providing new perspectives and concrete hints, not only for those who are about to start using Gemini but also for those who are already utilizing it.

This is a practical book for business professionals who are interested in AI but haven't yet incorporated it into their work, want to use their Google environment more effectively, and aim to turn generative AI into a tool that drives results rather than just a convenience.
