Yazawa Ventures

Mariko Yazawa, the firm's Founder and CEO, makes investment decisions as the sole-named principal. Her background includes a decade-plus spanning software consulting, over 70 startup investments at Samurai Incubate, and COO-level portfolio building at Plug and Play Japan. There is no publicly listed investment committee or additional general partners.

The firm describes itself as a seed-focused venture capital investor. Its thesis targets early-stage companies — specifically those at formation, startup, and early-expansion phases — with a thematic focus on the future of work in Japan. There is no public evidence of Series B or later-stage participation.

Sourcing is heavily relationship-driven and built around Mariko Yazawa's personal presence across Japan's startup ecosystem. She serves as a judge or mentor for events including IVS, Shibuya QWS Startup Award, GTIE, and NewsPicks' Make Money Survive pitch contests. The firm also operates a podcast interviewing early-stage founders, creating an inbound channel for seed-stage discovery.

Yazawa Ventures operates as an independent venture capital firm — specifically, a single-GP entity founded by Mariko Yazawa after her departure from Plug and Play Japan. Its legal structure includes Yazawa Ventures 1号投資事業有限責任組合, a Japanese investment limited partnership (Fund I), with no disclosed corporate parent or strategic LP control.

The firm concentrates on the future of work, split into two streams: tools for organizational transformation (enterprise efficiency, HR tech, employee engagement) and tools that support individual workforce participation (healthcare, education, childcare, eldercare). Its public tags and media appearances reinforce a dual interest in enterprise SaaS and social infrastructure.

All available evidence points to direct seed-stage investing. The firm has not disclosed any fund-of-funds activity, SPV structures, or LP commitments to other managers. Its vehicle is a single investment limited partnership making direct equity investments into startups.

She graduated from the State University of New York, then worked as a consultant and engineer at a BI/ERP software vendor handling credit risk and corporate due diligence. She moved into venture at Samurai Incubate, where she made over 70 startup investments, and later became COO of Plug and Play Japan, evaluating more than 150 global startups. She founded Yazawa Ventures in 2020 after having a child.
