Kufu Sumai

What Kufu Sumai does

Kufu Sumai is a Japanese housing services company that operates an integrated multi-product platform addressing both consumer home seekers and real estate professionals. Its core offerings include the O-uccino housing portal (covering rentals, new construction, resale, apartments, and detached houses), the Kurasumatch SaaS sales support tool for real estate agencies and home builders, the Kufu Ietate regional housing media brand, and the Kufu Ietate Counter physical consultation store network. Founded on October 1, 2018, and headquartered in Tokyo with additional offices in Shizuoka and Hamamatsu, the company is a wholly-owned subsidiary of Kufu Company Holdings (TSE Growth: 4376). Registered capital is JPY 90 million. Management is led by Representative Director Nagai Takenao, who joined from Amazon Japan, with a board that includes several other ex-Amazon Japan executives covering store strategy and SaaS sales.

The company's technology stack is built on proprietary portals, a CRM/SaaS platform with map-based property visualization, automated brochure generation, automated customer follow-up, and integrated online consultation rooms. Its newest capability is the Kufu Ietate Idea Board, an AI-powered sales support tool launched April 2026 that visualizes ideal home images and generates personalized catalogs in real-time during sales conversations, with reported 2.5x closing-rate uplift among top users. The platform's competitive foundation rests on 20+ years of accumulated housing domain data across the O-uccino portal and Kufu Ietate media properties.

Kufu Sumai generates revenue through four streams: subscription fees from Kurasumatch SaaS (Standard and Premium plans, pricing by inquiry) and portal listings; transaction/lead-introduction commissions from the counter network connecting home buyers with vetted builders; advertising and sponsorship from the Kufu Ietate media properties and housing fairs (Kufu Ietate Fair events); and event-driven revenue from large-scale regional housing exhibitions. Go-to-market is hybrid: self-serve digital onboarding for SaaS and portal users, paired with a physical counter store network that exceeded 20 locations by June 2025 across multiple Japanese prefectures, supported by content marketing, SEO, and earned media (industry publications and general business media).
