Tokyo is a vibrant innovation hub with ambitious goals to grow its startup ecosystem. Tokyo’s Startup Strategy "Global Innovation with STARTUPS" aims to create an ecosystem that nurtures startups in Japan by accelerating startups and promoting open innovation. The plan is related to the Startup Development Five-year Plan by the Japan government which has a goal of growing the number of startups to 100,000, with 100 of these being unicorns. The Japanese government aims to increase startup investment to $72.4 billion by March 2028, with $734 million government budget allocation earmarked to support Deep Tech-related startups and $2.2 billion dedicated to supporting drug discovery-related startups.

Tokyo’s startup support is robust, with a number of specialized services. Tokyo Metropolitan Government established the Tokyo Consortium with startups, investors, incubators, foreign and local governments, and industry associations to accelerate the growth of startups. The Tokyo Innovation Base opened in May 2024 as a major networking hub for domestic and international players. The Tokyo Venture Capital Hub serves as the first large-scale venture capital base in Japan, aiming to increase startup investment and strengthen investor collaboration.

SusHi Tech Tokyo 2024 is Asia's largest and Japan's only global innovation conference for startup ecosystems to solve global urban issues.
