New Value Creation through Four-Company Collaboration

*In alphabetical order

Located within the Mitaka Business Park operated by Atsuden, the combined strengths in entrepreneurship education, business know-how, information dissemination, and financial networks will enhance the space beyond a simple coworking facility—transforming it into a 'place where challenges accelerate.'

Specifically, to support young local talent, students will be granted free access to the coworking space. Additionally, members of the Musashino Valley community 'FLAGS,' composed of self-driven individuals, can use the space free of charge as an office, creating a venue where diverse challengers across generations can gather.

Furthermore, through collaboration with Seibu Shinkin Bank, a regional financial institution, and Bunshin Co., Ltd., which operates locally, the initiative will support and expand the activities of entrepreneurs and businesses within Mitaka City. Musashino Valley will serve as the central hub, aiming to realize an ecosystem where challenges emerge, are supported, and spread throughout the region.

Musashino Valley will launch the 'Musashino Valley Fellow' program, enabling students to actively participate in community building and event management. The program seeks individuals who do more than just use the facility—those who will plan initiatives, connect people, and help generate new challenges.

Details of the program will be announced at the comeback party 'Musashino Valley Reboot' on June 23 (Tue) at 7:00 PM. Students with interest are encouraged to attend.
