According to a report by Startup Genome, Tokyo ranks as the number one startup ecosystem in Japan, placing it among the top 15 globally. The city is home to over 2,000 startups, with a strong presence in sectors like AI, robotics, and fintech. Osaka and Kyoto are also notable hubs, contributing to Japan’s innovation landscape. In 2024, Japan saw venture capital investments amounting to $5.6 billion, reflecting a growing confidence in the potential of Japanese startups. The government has played a crucial role by introducing policies to foster entrepreneurship, such as the J-Startup program, which supports high-potential startups through funding, mentoring, and international networking.
Several Japanese startups have reached unicorn status, highlighting the dynamism within the country’s entrepreneurial ecosystem. Notable examples include Preferred Networks, an AI company valued at over $2 billion, and Mercari, an e-commerce platform that has expanded globally and listed on the Tokyo Stock Exchange with a market capitalization exceeding $7 billion. Other rising stars include the fintech firm Paidy, which was acquired by PayPal for $2.7 billion, underscoring the global interest in Japanese innovation.
These successes demonstrate Japan’s capability to produce world-class technology companies and underline the vibrant, evolving nature of its startup ecosystem.
