Frequently asked questions
How does Hiroshima Innovation Network source its deals?
The firm sources investment opportunities primarily through direct, relationship-based origination within Hiroshima Prefecture and the broader Chugoku region. By focusing on succession-driven transactions — where aging business owners actively seek transition partners — the firm accesses a proprietary deal pipeline that is largely invisible to competitive auction processes. This sourcing model relies on deep local networks, trust-based introductions from regional banks, accounting firms, and business associations rather than intermediated processes run by Tokyo-based investment banks.
What is Hiroshima Innovation Network's geographic focus?
The firm concentrates its investments in Hiroshima Prefecture and the surrounding Chugoku region of western Japan. This geographic specialization allows the firm to maintain dense local networks, conduct intensive on-the-ground due diligence, and provide hands-on post-acquisition support to portfolio companies. Unlike Tokyo-headquartered firms that cover the entire country, Hiroshima Innovation Network's value proposition is built on proximity to target businesses and regional market expertise.
