Unison Capital

Tatsuya Hayashi serves as Representative Partner and CEO, overseeing investment strategy and firm management. Founder John Ehara remains involved as Senior Advisor. The investment committee draws on leadership from both the Tokyo and Seoul offices to approve transactions across the firm's geographic mandate.

Unison relies on long-standing relationships with Japanese and Korean corporations, banks, and family business owners. The firm built a reputation for executing carve-outs from large conglomerates, including the acquisition of Nichii Gakkan's nursing-care business and SKC Kolon PI from a Korean industrial group. These networks generate pre-auction deal flow that bypasses competitive sale processes.

Unison Capital operates as a private equity firm managing institutional blind-pool funds, not as a family office. It raises committed capital from Japanese and global limited partners and invests through a formal fund structure, historically returning capital to LPs across successive vintage vehicles.

Unison Capital invests exclusively through direct control buyouts in mid-market companies. The firm does not operate a fund-of-funds program or make passive minority investments. Its strategy centers on obtaining majority stakes and driving operational change through board-level involvement.

Unison Capital does not publicly list excluded sectors, but the firm's track record shows no exposure to natural resources, heavy manufacturing, or commodity-linked industries. Its portfolio concentrates in healthcare services, consumer, business services, and industrial technology where it can apply operational expertise and demographic tailwinds.

There is no public record of a dedicated philanthropic vehicle or foundation established directly by Unison Capital. The firm operates strictly as an institutional private equity manager without a disclosed charitable arm, distinguishing it from family-office peers that often embed philanthropic structures into their architecture.

Unison Capital typically invests as lead or sole sponsor in its mid-market deals and does not actively promote co-investment syndicates. The firm's control-oriented strategy favors concentrated influence over portfolio companies, which limits the role of passive co-investors in its deal structures.
