Tokyo, Japan, April 27, 2021 – Mitsui Fudosan Co., Ltd., a leading global real estate company headquartered in Tokyo, announced today the launch of startup workspace THE E.A.S.T. , a startup workspace brand designed to make Tokyo’s east side a major aggregating point for startups. This project is being offered as a solution by 31VENTURES, a venture collaboration business whose goal is to engage in co-creation with startups.
THE E.A.S.T. Nihonbashi-Tomizawa-cho opened in April as the project’s flagship site.

Through 31VENTURES, Mitsui Fudosan has worked with ProtoStar Inc. to aggregate startups in Tokyo’s east side, centered around the Nihonbashi district, and since 2018 has been developing the E.A.S.T. concept* to promote open innovation. To date, this has involved offering entrepreneurship development programs, sponsoring events and other activities, but startup workspace THE E.A.S.T. is a new initiative designed to allow startups to connect with one another and provide a central workspace that will enable their businesses to run smoothly.

  • E.A.S.T. is an acronym for Empowering Ambitious Startups in Tokyo,and embodies Mitsui Fudosan’s desire to encourage ambitious startups in Tokyo’s east side area and enable them to fully demonstrate their capabilities.

startup workspace THE E.A.S.T. is a workspace brand that primarily targets mature entrepreneurs with business experience. Tokyo’s east side features a concentration of major firms, including companies listed on the First Section of the Tokyo Stock Exchange, and brings together a great many businesspeople with extensive experience. startup workspace THE E.A.S.T. offers a variety of workspaces designed to accommodate the needs of organizations at various stages of growth, from those just preparing to launch to those already in the midst of expansion. As a means of attracting highly passionate individuals, entrepreneurs are also interviewed in advance to assess the nature of their businesses, their vision and their potential for collaborating with Mitsui Fudosan. Once they have signed up, full-time support staff will meet with them regularly one-on-one, offer introductions to business partners and support development of sales channels, and will be quick to respond in terms of reviewing collaboration and funding needs. To drive the growth of these startups, the space is also equipped with facilities where entrepreneurs can hold presentations covering their products and business strategies.

As a symbol of mature entrepreneurs working in Tokyo’s east side, the startup workspace THE E.A.S.T. brand has been aligned with the 31VENTURES brand, which already operates five other offices. With THE E.A.S.T. Nihonbashi-Tomizawa-cho, which opened in April, positioned as the flagship site, these six offices will accelerate the creation of innovation in Tokyo’s east side.
