Frequently asked questions
Who runs investment decisions at 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.
How does Unison Capital source proprietary deal flow?
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.
Does Unison Capital participate in fund commitments or only direct deals?
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.
Which sectors does Unison Capital explicitly avoid?
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.
