About This Fund
Integral Fund V Series is the fifth Japan-focused mid-market buyout fund raised by Integral Corporation (Tokyo Stock Exchange: 5842), a private equity firm founded in 2007 and headquartered in Tokyo's Marunouchi district. The fund held its final close on 23 May 2024 at its hard cap of JPY 250 billion, approximately USD 1.6 billion, substantially exceeding its JPY 200 billion target and attracting commitments from Japanese and international investors including US pension funds, European institutions, sovereign wealth funds, and insurance companies. Approximately 50% of capital was sourced internationally. The fund is structured as three parallel vehicles: Integral 5 Limited Partnership, Innovation Alpha V L.P., and Initiative Delta V L.P. (collectively the Fund V Series), and represents the fourth-largest Japan-focused buyout vehicle raised by an independent manager by size.
Integral Fund V invests primarily in buyout and effective-control opportunities in Japan's middle market, targeting companies with enterprise values of JPY 10 to 50 billion. The fund pursues three primary deal types: founder succession situations capitalising on Japan's structural generational transition in family-owned businesses, corporate carve-outs from large conglomerates divesting non-core assets, and take-private transactions. Value creation is driven by two proprietary frameworks: the i-Engine system, which embeds investment professionals within portfolio companies for multi-year operational secondments at the gemba, and Deal Inducing Investment, under which Integral co-invests balance sheet capital alongside the fund to align incentives with founders and support IPO-exit pathways. The fund targets approximately 13 to 14 investments with deal sizes of JPY 2 to 40 billion, acquiring companies at 5 to 8x EBITDA.
Integral's track record across earlier funds demonstrates consistent outperformance in the Japanese middle market. Fund II returned 2.9x gross MOIC; Fund III achieved 2.1x gross MOIC with 86% of capital realised; and Fund IV was tracking at 1.9x gross MOIC with 70% deployed within three years. Collectively, Funds I to III delivered 2.5x gross MOIC and 25.8% gross IRR across 31 investments and 16 exits, including 7 IPO listings on Japanese exchanges. Representative portfolio companies include Skymark Airlines, Yohji Yamamoto, Apaman, QBnet Holdings, and BPS. In September 2023, Integral became the first Japanese private equity firm to list on the Tokyo Stock Exchange, with total AUM reaching JPY 470 billion at Fund V's closing.
