Announcement of the Establishment of New Company "Shinkeisha Inc."

This is an announcement regarding the establishment of "Shinkeisha Inc." by Kensaku Oka. Concurrently, Mr. Oka retired as the Representative Director of Study Hacker Inc. in April 2026. Shinkeisha Inc. will take over the educational media "STUDY HACKER" and "Kodomo Manabi Lab," along with their related SNS accounts, which were operated by Study Hacker. Shinkeisha Inc. will develop a business providing outsourced owned media editorial department functions to companies, utilizing its 15 years of expertise in media operation.

**Background of Establishment**

In 2010, Kensaku Oka founded Keigakusha Inc. in Kyoto and launched the educational media "STUDY HACKER." Services born from this media include the English coaching schools "ENGLISH COMPANY" and "STRAIL." The steady recognition gained by owned media consistently supported the growth of ENGLISH COMPANY and STRAIL.

Shinkeisha Inc. was established to take over the media business operated by Study Hacker and to embody the spirit of the original Keigakusha in a new form. The company name "Shinkeisha" encapsulates the intention of being a "New Keigakusha."

**Business Activities**

Many good services and products remain unknown and thus unsold – Shinkeisha Inc. addresses this challenge. We offer complete outsourced owned media editorial department functions, enabling companies to gain recognition through their own media and in their own words. Based on the concept of "Owned Media 2.0," which treats various SNS platforms like X, Instagram, YouTube, and Facebook as independent media, we design, plan, produce, and operate recognition initiatives that lead to business results.

This expertise stems from the practical operation of the following media and SNS accounts inherited from Study Hacker, which serve as proof points for clients:

* STUDYHACKER (studyhacker.net) – An educational media focusing on learning, working styles, and thinking methods. * Kodomo Manabi Lab – A media focusing on children's learning and growth.
