■ About ICT Startup League
This is a support program launched in FY2023, initiated by the Ministry of Internal Affairs and Communications' "Start-up Creation-type Germinating Research and Development Support Project."
The ICT Startup League supports startups through four main pillars:
1. R&D Funding / Hands-on Support
Up to 20 million JPY in research and development funding is provided in the form of a grant. Additionally, through hands-on support, the selection and evaluation committee members who were involved in the selection process continue to stand by the startups to promote their growth. A support system akin to "fandom" or "championing" (Oshi-katsu) is established, where committee members provide continuous support—such as advice on business plans and offering growth opportunities—to companies they highly value and are determined to see succeed.
2. Discovery & Development
The league provides opportunities for learning and networking to promote the business growth of league members.
It also seeks to discover aspiring entrepreneurs to broaden the base of the ecosystem.
3. Competition & Co-creation
Functioning as a positive competitive arena similar to a sports league, startups learn together and compete to win the necessary funding (up to 20 million JPY). It also provides a space for co-creation where league members can collaborate to expand their businesses through various opportunities, such as sessions with selection and evaluation committee members.
4. Dissemination
The league disseminates information about the members' initiatives in collaboration with media outlets! By letting more people know about these businesses, the league aims to expand opportunities for new matches and chances.
