Best Unicorn startups in Japan 2025

In the last decade, Japan’s startup ecosystem has been experiencing steady growth. It is drawing in top-tier talent to fuel the expansion of high-growth startups. Historically, a major constraint on Japan’s startup scene had been the lack of labor market dynamism, with top talent often bound in lifetime employment arrangements at established corporations.

However, a notable shift is underway, thanks to increased investment and a shift in mindset that encourages entrepreneurship. It is largely driven by a government keen on fostering innovation.

A strong network of support organizations spread across various centers in the country underscores Japan’s commitment to nurturing the startup scene. Notably, the Japan External Trade Organization (JETRO) leads initiatives such as the Startup City Acceleration Program, which assists startups in their global expansion efforts.

Moreover, Japan’s governmental entities like the Tokyo Metropolitan Government and municipalities such as Startup Fukuoka City and Startup City Sapporo, along with initiatives like Shibuya Startup Support are actively working to promote and assist their respective startup ecosystems. The implementation of Japan’s Startup Visa in key locations like Fukuoka City and Kobe City further solidifies the country’s commitment to attracting and retaining entrepreneurial talent.

The trajectory of the country’s startup ecosystems appears poised to garner even greater global recognition in the foreseeable future with fintech and healthtech sectors showing significant promise within Japan.
