BUILD's First Fund Attracts Major Investment to Fuel Deep Tech Innovations in Japan

The Rise of BUILD's First Venture Fund in Japan



In an exciting development for the Japanese deep tech landscape, BUILD, a venture capital firm founded in Tokyo, has announced that its first fund, BUILD1, is gaining traction with significant contributions from major financial institutions. Following the investment from the Tokyo Metropolitan Government, the Development Bank of Japan and Shoko Chukin Bank have joined as limited partners in this initiative, signaling a robust vote of confidence in the fund’s objectives.

Fund Overview



The goal of BUILD1 is ambitious—with an intended fund size of 80 to 100 billion yen. As the fundraising continues toward its final close, BUILD aims to mobilize resources that will support the development of next-generation energy solutions, decarbonization technologies, semiconductor advancements, and disruptive innovations in quantum and aerospace sectors.

Addressing Challenges in Japan's Startup Ecosystem



Japan possesses a wealth of remarkable research findings and technologies. However, there has been a significant gap between academic achievements and their commercialization in the industrial arena. This has left the country lagging behind Western nations in terms of the number of startups and their funding levels. BUILD is tackling this challenge head-on through a unique approach known as 'Company Creation.' This method emphasizes collaboration with top universities and research institutions across the nation to translate outstanding research into viable business ventures.

BUILD fosters the development of startups by carefully matching entrepreneurs with skilled management teams, negotiating patent licenses, and providing initial funding. This hands-on approach ensures that each venture has the best possible foundation for success.

Long-Term Commitment to Deep Tech



Recognizing the inherent challenges within the deep tech sector, which often requires extensive time for technology development and business establishment, BUILD has established an operational period for this fund that extends up to 15 years, with the possibility of a three-year extension. This long-term vision is designed to accompany startups through their early stages, leading to successful commercialization and eventual global scaling.

The objective is clear: to convert Japan's exceptional research achievements into practical applications that not only benefit society but also propel Japan’s economic growth by nurturing the next generation of leading companies.
