## Questions

### Who controls investment decisions at J-Will Partners?

Satoshi Yajima serves as Chief Investment Officer and leads the investment committee alongside CEO Tadashi Shimada. Both are founding managing partners who have worked together since J-Will's 2005 launch. The investment committee operates with a consensus-driven model typical of Japanese partnerships, and no external limited partners hold veto rights over individual deals.

### How does J-Will source its proprietary deal flow?

J-Will's sourcing is relationship-driven, built on the founders' decades-long networks within Japanese corporate planning departments and regional bank advisory desks. The firm targets non-auction situations: subsidiaries that parent companies have not publicly flagged for sale, and SME owners approaching retirement who begin confidential succession discussions through trusted intermediaries rather than competitive auctions.

### What investment structures does J-Will typically use?

J-Will executes majority control buyouts, acquiring 100% of equity in most transactions. The firm does not operate as a minority-growth investor or venture capital provider. In select cases, J-Will has structured partial exits where it retains operational control while bringing in a co-investor or completing a recapitalization, as seen in a 2023 healthcare transaction.

### Which sectors does J-Will prioritize, and which does it avoid?

J-Will invests across industrials, consumer products, business services, and healthcare services. The firm has avoided financial services, real estate development, and technology startups — sectors where its operational improvement playbook does not directly apply or where the regulatory environment in Japan constrains buyout structures.

### Does J-Will Partners maintain a fund-of-funds structure or invest in third-party funds?

J-Will does not operate as a fund-of-funds and does not commit to external private equity funds. The firm only deploys capital into direct control buyouts of Japanese companies. Limited partners commit to J-Will's flagship vintage funds, which are blind-pool vehicles with a standard 10-year life.

### How is J-Will Partners' fundraising positioned with Japanese institutional LPs?

J-Will's limited partners are primarily Japanese — including major banks, pension funds, and life insurance companies. The firm has raised multiple vintage funds, with Fund IV reported active as of 2024. The LP base reflects the founders' long-standing institutional relationships dating to their tenure at Yasuda Enterprise Development, a respected Japanese venture capital group.
