About the Japan Angel Investors Association

About Image


While the total amount invested by angel investors in the U.S. has increased to the same level as that of venture capital (VC), the total amount invested by angel investors in Japan is only a few percent of that of VC. In order for Japanese startups to grow, it is necessary to increase the amount and number of investments by angel investors, and it is also essential to improve literacy in angel investing, such as avoiding excessive stock ownership by angel investors and setting appropriate valuations.


The Japan Angel Investors Association was established with the aim of fostering the development of Japan’s angel investment culture. It builds a platform for networking and sharing information among angel investors, supporting the enhancement of their knowledge and skills. Additionally, the association develops angel investment guidelines for investing in startups and makes policy recommendations to the government, thus improving Japan’s angel investment environment. Through promoting healthy development, the association plays a key role in supporting the growth of startups.
