What Integral Corporation does
Integral Corporation (株式会社インテグラル, ticker 5842) is a Tokyo-headquartered, Tokyo Stock Exchange Growth Market-listed private equity investment manager founded in 2007 by Reijiro Yamamoto, Yoshihiro Hemmi, Kensaku Mizutani and Nobuo Sayama. The firm manages five successive buyout fund vintages (Integral Fund I through Fund V, with Fund V holding over JPY 100 billion in committed capital) and a dedicated real estate fund (Integral Real Estate Fund I), and operates an "i-Engine" hands-on value-creation program in which its ~70 investment professionals are dispatched into portfolio companies to lead governance, sales, IT, overseas expansion and PMI work. Investment themes center on Japanese mid-to-large-cap companies — turnaround situations, business succession, MBOs, carve-outs from large corporates, and growth capital — spanning manufacturing, retail, fashion, healthcare, technology, transportation and real estate, with 30+ portfolio companies that include category leaders such as Tekscend Photomask (global #1 semiconductor photomask merchant market), Asahi Kasei Medical's blood purification business (#1 in Japan apheresis), Yohji Yamamoto, Medicom Toy (BE@RBRICK), Primo Global Holdings and Japan Animal Care Holdings.
The firm's revenue model rests on two streams: recurring management fees on committed/invested capital across multiple fund vintages and the real estate fund, and performance-based carried interest from successful realizations such as the 2025 exits of Tekscend Photomask and Primo Global Holdings and the partial exit of Toyo Engineering. Go-to-market is enterprise field sales on both sides of the table — direct sourcing of Japanese investment opportunities without intermediaries, and direct fundraising from institutional LPs (pension funds, insurance companies, university endowments, public organizations). Distribution has been extended cross-border via a 2025 joint venture with Granite Asia and a tech-focused vehicle, Integral GlobalTech Partners, which has deployed capital into AI-native targets such as Notta (voice intelligence) and Daloopa (AI financial data).
Integral has been a signatory to the UN Principles for Responsible Investment (PRI) since 2016 and incorporates ESG screening throughout its investment process. The leadership bench is unusually academic and blue-chip for a Japan-focused mid-cap GP — partners hold MBAs/doctorates from Wharton, Harvard, MIT, INSEAD, Berkeley, Tokyo University, Keio and Hitotsubashi, and the outside director roster includes Hirotaka Takeuchi (Hitotsubashi/HBS emeritus, co-author of "The Knowledge Creating Company") and AI expert Masaru Tomita (Keio, Carnegie Mellon). Following its September 2023 TSE listing and 2024 Fund V / Real Estate Fund closings, the firm has executed a notable run of investments in 2025–2026 (Asahi Kasei Medical carve-out completion, Golf Digest Online MBO, Medicom Toy, MUTOH Holdings tender, At Home Holdings, Yasojima Proceed, STPR) alongside active buy-and-build consolidation in veterinary healthcare via the Japan Animal Care / ANCHORS platform.

Integral Corporation competitors and assessment
Company assessmentDirect peers
- Unison Capital: One of Japan's leading independent mid-market buyout firms founded in 1998. Several Integral founders (including Yoshihiro Hemmi and Nobuo Sayama) previously worked at Unison, making it the most directly comparable peer by investment style, vintage, and target market.
- JAFCO Group: Japan's largest venture capital and buyout firm with a listed parent (TSE). Like Integral, JAFCO manages multiple fund vintages serving Japanese mid-cap companies across venture, growth, and buyout stages, and is a directly comparable listed Japanese PE platform.
- Advantage Partners: Tokyo-based mid-market buyout firm investing in Japanese companies across turnaround, succession, and growth situations. Highly comparable to Integral in fund size, investment themes, and target company profile.
- Polaris Capital Group: Tokyo-based private equity firm investing in Japanese mid-cap companies through buyout and growth capital strategies. Operates multiple fund vintages comparable to Integral's Fund I-V series.
- Nihon M&A Center: Listed Japanese M&A intermediary specializing in business succession deals between SMEs and corporate buyers. Comparable in its focus on Japan's business succession opportunity set, which is one of Integral's core investment themes.
- J-Will Partners: Japanese private equity firm focused on business succession, MBO, and growth investments in mid-cap Japanese companies. One of Integral's director-level team joined from J-Will, indicating direct overlap in deal sourcing and execution approach.
- Industrial Growth Platform Inc. (IGPI): Japan-focused turnaround and value-creation firm founded by former Industrial Revitalization Corporation of Japan leadership. Comparable to Integral in its operational, hands-on approach to Japanese mid-cap turnaround investing.
Broad incumbents
- Carlyle Group (Japan): Global alternative asset manager with established Japan operations and dedicated Japan buyout funds. Overlaps with Integral in target market but operates at much larger scale and broader sector mandate.
- KKR (Japan): Global private equity firm with a dedicated Japan platform (KKR Japan) investing across buyout and growth strategies. Competes for some of the same Japanese mid- and large-cap targets as Integral but with significantly greater AUM.
- Bain Capital (Japan): Global private equity firm with active Japan buyout operations, competing for Japanese mid- and large-cap opportunities. Broad incumbent with overlapping Japanese deal flow but global rather than Japan-specialist mandate.
