i Mercury Capital

Koki Kimura serves as President and Representative Director of MIXI, Inc., the parent company, and oversees i Mercury Capital's operations. Kazuhiro Shin is Vice President of i Mercury Capital, Inc. Kenji Kasahara, the founder of MIXI, provides strategic direction as Chairman. The firm's investment committee likely includes these executives, though no formal committee structure is publicly disclosed.

The firm leverages MIXI's corporate network and relationships, particularly via its joint venture with Mitsui Fudosan for the TOKYO-BAY Arena. Its ownership of sports teams (Chiba Jets Funabashi, FC Tokyo) provides direct access to venue development and franchise investment opportunities. The firm is a member of the GCV Leadership Society, indicating engagement with global corporate venture capital networks.

i Mercury Capital is structured as a wholly owned subsidiary of MIXI, Inc., a publicly traded company on the Tokyo Stock Exchange. It functions as MIXI's corporate venture capital and investment arm, not as a family office. However, because MIXI was founded by Kenji Kasahara, the investment vehicle may hold some characteristics of a single-family office for the Kasahara family, though public records describe it as a corporate subsidiary.

The firm targets a broad range from early-stage (including startup) to expansion and late-stage opportunities. Its known investments tilt toward later-stage projects like the large-scale TOKYO-BAY Arena real estate development and outright ownership of professional sports teams. Early-stage activities are not publicly documented.

The firm focuses on real estate (particularly large entertainment venues) and sports (ownership of Chiba Jets Funabashi and FC Tokyo). It invests in Japan, with a concentration in the Greater Tokyo area. No explicit sector exclusions are publicly stated, but its known deals cluster around real estate and sports rather than technology or financial assets.

The firm is known only for direct investments in assets it owns outright, such as the TOKYO-BAY Arena joint venture and its sports teams. No public record indicates fund commitments to external managers. Its corporate structure as a subsidiary suggests it deploys parent-company capital directly.

i Mercury Capital is a 100%-owned subsidiary of MIXI, Inc. MIXI is a Japanese social-media and gaming company founded by Kenji Kasahara in 2004, publicly listed on the Tokyo Stock Exchange since 2006. The investment arm was created to deploy MIXI's capital into assets outside the core social-media business, such as real estate and sports.
