Frequently asked questions
Who runs investment decisions at Japan Investment Adviser?
Naoto Shiraiwa, President and CEO, leads the investment committee. A former Mitsubishi Corporation executive, he co-founded JIA in 2006 and remains the firm's key decision-maker. Senior partners with backgrounds at Japanese trading houses and domestic banks support origination and underwriting, per the firm's official website.
What deal size and stage does JIA target?
JIA targets Japanese companies with ¥1 billion to ¥10 billion in annual revenue, writing equity checks between ¥500 million and ¥3 billion per deal. The firm executes control buyouts exclusively — no minority investments, no venture-stage exposure — focusing on corporate divestitures, founder successions, and operational turnarounds.
Does JIA invest outside Japan?
JIA's primary investment footprint is Japan's Kanto and Kansai regions. The firm has extended into select broader East Asian opportunities, but the vast majority of deployed capital remains within Japan, where its structural sourcing edge is strongest.
