Accelerating Innovation: The Rise of Japanese Startups

Japanese startups, once the “benchwarmers” sitting on the sidelines of Japan’s business sector, have now moved onto the main court and are poised to become their next major economic players. Backed by Japan’s main business association, Keidanren, and new government programs such as the Integrated Innovation Strategy 2022, Japanese entrepreneurs are receiving the jumpstart they need to accelerate Japan’s economic revitalization.

On October 12, 6:00PM (PT) // October 13, 10:00AM (JT), the SVJP October Benkyokai featured two successful Japanese startups who shared their entrepreneurial journeys and how they’re accelerating Japan’s technological growth. The first featured startup, Alpaca, builds a financial services infrastructure for stock and crypto investing. Yoshi Yokokawa reflected on his experiences and learnings as the Co-Founder and CEO. The second featured company, Diarkis, is a middleware software that allows remote users such as online gamers to interact and communicate in real-time. Founder & CEO Nobuyori Takahashi and COO & CFO George Takao represented Diarkis to explore their challenges and successes.
