Born in Yokohama in 1983. After graduating from high school, he moved to the United States to pursue a career as a musician and graduated from the Music Department of the School of Arts at Citrus College. After returning to Japan, he made his CD debut. Inspired by his experiences in the U.S., he started a business, but later went through bankruptcy and business transfer. These experiences led him to renew his philosophy, believing that “the mission of a company is to contribute to everything it touches.”

In 2007, he founded Diamond Media Co., Ltd. From the outset, he systematized management transparency, adopting unique practices such as: “disclosing all salaries, expenses, and financial statements,” “abolishing positions and titles,” “freedom in working hours, location, and holidays,” “encouraging entrepreneurship and side businesses,” and “electing executives and representatives.” This distinctive philosophy of “management without management” attracted attention as a next-generation corporate model.

In 2017, the company received the White Company Award. As a leading figure in Japan on decentralized autonomous organizations (DAOs), teal organizations, and holacracy management, he has contributed to media, given lectures, and provided organizational support. In 2018, he coined the term “Jinen (Natural) Management” and established the General Incorporated Association for Natural Management Research. His work extends beyond organizational theory, focusing on themes such as “self-organization, circular economy, and interconnectedness,” and he has engaged in extensive research and activities aimed at realizing new forms of society—such as sustainable social systems, economies beyond monetary exchange, and updates to democracy.

He has also dedicated efforts to promoting DX (digital transformation) in the real estate sector, founding the Real Estate Tech Association of Japan in 2018 and serving as its first representative director. He has also held positions including: Director of the Living Tech Association, Steering Committee Member of the IT Division at the Japan Property Management Association, Advisor to the Ministry of Land, Infrastructure, Transport and Tourism’s Public Real Estate Utilization Project, and Committee Member of the Housing Ground Information Promotion Council.

As a co-executive of eumo, a nonprofit company that operates a community currency platform founded by Kazuhiko Arai, co-founder of Kamakura Investment Trust, he is engaged in new financial systems. At the same time, he manages numerous for-profit and nonprofit organizations working on SDGs, organizational development, wellbeing, fair trade, ethical consumption, regional energy, regional revitalization, and agricultural DAOs.

In community activities in Setagaya, he serves as a board member of the NPO neomura, supporting local festivals, cleanup initiatives, agricultural communities, and the issuance and circulation of urban community currencies. In 2019, he was also selected as an evangelist for Setagaya Ward’s hometown tax donation campaign.
