What OASIS FUND does

OASIS FUND is a Tokyo-based seed venture capital firm established in December 2024 by two General Partners — Hashida Kazuhide (橋田一秀, founder and former CEO of Peraichi until April 2023) and Takahagi Hiroyuki (高萩浩之, former CFO of Shumatsuwalker through its 2023 sale to CrowdWorks). The firm operates as a business-creation-type fund offering four investment tracks: co-founding investments up to ¥50M with the lead GP working operationally inside the portfolio company during launch; seed lead investments up to ¥30M with weekly mentoring; follow-on investments up to ¥10M for pre-Series A rounds on a hands-off basis; and Micro PE/Spinout investments taking 51%+ majority stakes for M&A-driven business succession and corporate spin-outs.

The firm's core differentiator is active co-founding engagement rather than passive capital provision, combined with an explicit dual IPO/M&A exit strategy evaluated from day one of each investment. OASIS FUND operates SHIBUYA STARTUP OASIS, a free community space located five minutes from Shibuya Station, which functions as the fund's primary deal-sourcing hub and as a peer-support venue for portfolio founders. The firm also convenes portfolio retreats and pitch-brushup sessions that combine fund portfolio companies with Hashida's 77 prior personal angel investments.

OASIS FUND is privately held with no disclosed institutional backing, no parent company, and no public funding-round history. Its geographic focus is Tokyo, Japan, and its disclosed portfolio includes at least seven companies spanning technology, retail/consumer, tourism, transportation, and robotics/AI (Nagaku, Maison Chatons, Hagino Tourism, IIBA, Habshuttle, Irusiru, and SYN Robotics). Revenue is generated through equity ownership in portfolio companies with returns realized via IPO or M&A exit; no management fee or carried interest figures are publicly disclosed. The firm is actively operating and participating in industry events including IVS2026 Kyoto and a SusHi Tech Tokyo 2026 co-hosted partner event with Nulab Inc.
