What MPower Partners does
MPower Partners is a Tokyo-headquartered venture capital firm founded in May 2021 by three former Goldman Sachs executives — Kathy Matsui, Yumiko Murakami, and Miwa Seki — who collectively hold all General Partner seats. The firm invests in tech-enabled startups addressing societal challenges, applying a proprietary ESG framework across deal sourcing, due diligence, and post-investment support. It became a United Nations Principles for Responsible Investment (UNPRI) signatory in June 2021.
The firm operates a multi-fund structure: MPower Partners Fund I (middle-to-later stage, Japan and global), MPower Partners Fund II (launched May 2025, targeting global unicorns from Japan and beyond under the 'Japan Dynamism' theme), and WPower Fund (Japan's first VC fund dedicated to female founders and women-empowerment businesses, early stage, Japan-focused). The portfolio spans frontier technology themes including generative AI (Sakana AI, Japan's most valuable unicorn at ~$2.65B), AI semiconductors (EdgeCortix), quantum communications (LQUOM), nuclear fusion materials (MiRESSO, EX-Fusion), rare earths (Phoenix Tailings), sovereign cybersecurity (Nihon Cyber Defence), and laser communications (Transcelestial). Approximately 35% of portfolio companies are founded or led by women or other diverse founders.
The business model is standard venture fund management: management fees on committed and deployed capital across the fund vehicles, plus carried interest on successful exits. Limited Partners are not publicly disclosed but are understood to include institutional investors and development organizations. The firm is sales-led and relationship-driven, sourcing deals through proprietary networks rather than inbound funnels, and monetizes its global investor and strategic network (e.g., MUFG, Khosla Ventures, Axiro/CG Power, Spiral Capital, Eni Next) as a differentiated value-add beyond capital deployment.

MPower Partners competitors and assessment
Company assessmentDirect peers
- GLOBIS Capital Partners: Japan-focused early-stage VC with multiple funds and a strong founder network. Comparable fund structure, stage, and Japan-centric thesis to MPower's funds.
- World Innovation Lab (WiL): Japan-focused early- and growth-stage VC with cross-border reach and a strong corporate LP base. Highly comparable to MPower in stage, Japan Dynamism-style thesis, and international LP appetite.
- Spiral Capital: Japan-based VC with deep-tech and growth-stage focus and a domestic LP base. Directly comparable: co-invested with MPower in MiRESSO's Series A and competes for similar Japan deep-tech rounds.
- Global Brain: One of Japan's largest independent VCs, operating multiple funds across stages and themes. Comparable in operating multiple fund vehicles and investing across Japan frontier-tech themes.
- DG Incubation: Japan-based seed-to-Series A VC affiliated with Digital Garage, active in frontier tech and Web3. Comparable check size, Japan focus, and stage coverage to MPower's WPower and seed portions.
- Incubate Fund: One of Japan's largest seed-stage VCs by portfolio count with multiple regional funds. Comparable stage focus (seed/early) and Japan-centric thesis to MPower's WPower Fund.
Emerging players
- Obvious Ventures: US-based VC explicitly purpose-driven and sustainability-focused. Closest Western analog to MPower's ESG-integrated investment thesis, though operating in a different geography.
- Khosla Ventures: US-based, frontier-tech focused VC and repeat MPower co-investor in Sakana AI. Comparable only as a syndicate partner in deep-tech rounds rather than a direct competitor.
Broad incumbents
- JAFCO: Japan's largest VC and PE firm with broad sector exposure across stages. A scaled incumbent benchmark for AUM, fund cadence, and exit activity in the Japan VC market.
- Allen & Company (Japan operations): Established cross-border advisory and investor with Japan and frontier-tech exposure. Comparable as a high-end advisor/investor overlapping with MPower's LP and co-investor network.
