What DIMENSION does

DIMENSION株式会社 (DIMENSION, Inc.) is a Tokyo-headquartered venture capital firm founded in October 2019 that invests in Japanese seed, early-stage, and pre-IPO growth-stage startups. The firm was originally formed as a wholly-owned subsidiary of Dream Incubator Inc. and became independent via a management buyout led by CEO Takamitsu Miyaso in September 2021. DIMENSION operates two funds: Fund 1 (formed October 2019, invested in 24 companies with 3 IPOs) and Fund 2 (established April 2022 with a target size of approximately 10.15 billion yen / ~$67M USD, backed by Japan Investment Corporation, 11 listed-company founders, overseas institutional investors, corporates, and individual LPs). The firm describes its model as a '360° fund' that pairs capital with hands-on business-growth consulting, organizational development support, and IPO/M&A execution expertise, with reported aggregate track record of 38 IPOs and 66 M&A transactions (including results attributable to originating parent Dream Incubator).

DIMENSION's core revenue mechanics are standard VC fund economics: recurring management fees on committed/invested capital across its two funds, plus carried interest realizations from successful exits. The firm differentiates via its LP base — founders and CEOs of 11 listed Japanese companies (Adways, PR TIMES, HEROZ, kubell, Goodpatch, Direct Marketing MIX, Coconala, CINC, among others) who provide mentorship and business-development support to portfolio founders. Recent portfolio exits include AnyMind Group (IPO 2023), COVER Corporation (IPO 2023), NYLE (IPO 2023), Alt (IPO 2024), BABY JOB (IPO 2024), and BATONZ (IPO 2026); a notable 2026 secondary exit was the Anthropic acquisition of Coefficient Bio (a DIMENSION-backed biotech) for approximately $400M in Anthropic stock.

The firm operates from the Azabudai Hills 'Tokyo Venture Capital Hub' (Kengo Kuma-designed office, co-located with ~70 VCs and CVCs), is a member of the Japan Venture Capital Association, and operates a sub-brand media platform called DIMENSION NOTE that publishes founder interviews. As of March 2026, DIMENSION is publicly scouting approximately $700 million for a successor fund, with early 2026 deal activity indicating expansion beyond Japan into UK, Canadian, and US biotech and lab-automation companies (Automata, Congruence Therapeutics, Aspect Biosystems). The firm has 1-10 employees.

Broad incumbents

• JAFCO Group: Japan's largest publicly listed venture capital firm, managing hundreds of billions of yen across multiple vintages and stages. Directly comparable as a Japanese VC firm investing across stages, but with substantially larger AUM, broader stage coverage, and public-company scale.
• SBI Investment: One of Japan's largest VC arms affiliated with SBI Group, with multi-stage investing and very large AUM. Comparable as a Japanese institutional VC, but at vastly greater scale and broader stage coverage including public-equity-adjacent growth investing.
• MUFG Innovation Partners: CVC arm of MUFG Bank investing in Japanese growth-stage startups with strategic partnership angles. Comparable to DIMENSION's institutional/LP relationships and Japanese growth focus, but with corporate-strategic capital base and much larger check sizes.

Direct peers

• Global Brain: Leading Japan-based VC firm investing from seed through growth stages with both domestic and cross-border deal flow. Highly comparable to DIMENSION in stage focus, geographic base in Japan, and emphasis on supporting founders beyond capital — operates at meaningfully larger AUM.
• East Ventures: Japan- and Southeast Asia-focused early-stage VC firm with strong seed/Series A orientation. Comparable to DIMENSION's early-stage, high-volume seed investing approach and similar LP base including Japanese institutional investors.
• ANRI: Tokyo-based early-stage VC focused on Japanese seed and pre-seed startups with strong founder mentorship orientation. Highly comparable to DIMENSION in stage, geography, and 'founder-first' value proposition; smaller fund sizes than DIMENSION's planned next vehicle.
• World Innovation Lab (WiL): Japan-rooted VC with cross-border (US/Japan) early-to-growth stage focus and corporate LP backing. Comparable to DIMENSION in bridging Japanese startups with global growth capital, with comparable AUM and stage profile.
• Incubate Fund: Independent Japanese seed-stage VC that invests broadly across verticals with founder-support orientation. Directly comparable to DIMENSION's Fund 1 seed strategy and stage focus, though generally earlier-stage and with more diversified portfolio.
• BEENEXT: Japan/Singapore-based early-stage VC investing across Asia with founder community focus. Comparable to DIMENSION in seed/Series A stage, founder-network-driven deal flow, and cross-border ambition.

Regional players

• JAFCO Asia (JAFCO Group subsidiary): Singapore-headquartered VC arm of JAFCO focused on Southeast Asia early-to-growth stage investing. Comparable as a Japan-rooted VC with cross-border early-stage mandate, similar in stage profile to DIMENSION Fund 2's growing cross-border thesis.
