Share Company

What Share Company does

SHARE Company (株式会社シェアカンパニー) is a Tokyo-based vertically integrated real estate operator founded in July 2009 by Representative Director and CEO Sasaki Shota, headquartered in Kitasando, Shibuya ward. The company acquires vacant, idle, or aging buildings primarily in central Tokyo (concentrated in Shibuya, Setagaya, Chuo, Meguro, and Toshima wards), renovates them via affiliated group company WAM Architecture (a licensed architectural firm), and operates them across multiple asset types. Its sub-brands include COURI (share houses, including MATE Ikebukuro, a 61-unit hybrid share-house/apartment building), THE FORUM (share offices and event spaces at Kitasando and Setagaya), WISE OWL HOSTELS (accommodation in Hatchobori and Aobadai), SOUND BAR HOWL (event venue), and SHARE PARK (a share house and apartment search portal).

The business model spans four revenue streams: (1) one-time real estate trading, where the company purchases, renovates, and resells subdivided condominiums and small buildings (multiple Shibuya acquisitions and sales documented 2024-2026); (2) recurring rental management, including the Zero-Yon plan launched October 2024, which waives management, restoration, and contract fees in exchange for converting vacant units into short-stay accommodation; (3) nightly short-stay and minpaku/ryokan operations under MLIT license F04612 (registered June 2025), with sequential hotel launches in Tomigaya from April 2025 through February 2026; and (4) hourly event and filming space rentals (¥10,000-¥25,000/hour across THE FORUM venues, WISE OWL HOSTELS spaces, and SOUND BAR HOWL). Customer segments include Tokyo property owners seeking to monetize vacant stock, young professionals and international students as residential tenants, domestic and inbound travelers as short-stay guests, and event/film production clients.

The company's primary go-to-market is direct relationship-based sales to property owners, supplemented by self-service brand websites and the SHARE PARK portal for residential and event bookings, and four international student housing referral partnerships (UF Japan, onjpn, RE Network Tokyo, JSB Network). Registered capital is ¥35 million; revenue and headcount are not publicly disclosed. No proprietary technology platform, app, API, or AI/ML capabilities are disclosed; differentiation rests on the integrated acquisition-renovation-operations workflow, the multi-brand portfolio built over 17 years, and a documented 97.6% average occupancy across share houses (May 2025-April 2026).

Scale indicators3 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Airbnb: Global short-term rental marketplace. Vastly larger, but competes for minpaku and short-stay booking demand that ShareCompany's Zero-Yon-converted vacant units and WISE OWL HOSTELS serve. Represents both a distribution channel and competitive threat for Japanese operators.
• Hoshinoya Resorts (星野リゾート): Japan's premier upscale domestic resort operator running ryokan, hotels, and experiential lodging properties. Operates the same acquisition-renovation-operation playbook for vacation accommodation, albeit at a higher price point than ShareCompany's WISE OWL HOSTELS and minpaku inventory.
• Daito Trust Construction (大東建託株式会社): Japan's largest rental property management and construction company, managing over 1 million rental units nationwide. Provides a benchmark at scale for ShareCompany's rental management business and competing managed-property ecosystem.
• Mitsui Fudosan (三井不動産株式会社): One of Japan's largest real estate developers and lessors, with a vacation rental / resort segment and extensive property management operations. Comparable at scale to ShareCompany's full-service property operations across residential, hospitality, and event space.

Direct peers

• Global Agents (株式会社グローバルエージェンツ): Tokyo-headquartered share house and co-living operator running brands such as Social Residence and Global Residence. The most direct comparable peer to ShareCompany's COURI and MATE share house operations, serving the same young professional and international student demographic in central Tokyo wards.
• JSB (株式会社ジェイ・エス・ビー) / Cross House: Major Japanese student housing operator running the Cross House share house brand targeting international students. Notable as both a direct competitor to ShareCompany's COURI student-focused share houses and an existing distribution partner through JSB Network.
• Resol Holdings (リソルホールディングス): Japanese hospitality operator with vacation resorts, hotels, and golf businesses. Comparable to ShareCompany's lodging operations (WISE OWL HOSTELS and minpaku) and to its vacation-acquisition-to-renovation-to-operation workflow.
• Space Market (スペースマーケット株式会社): Japan's leading event-space and meeting-room booking platform (TSE: 4197). Directly comparable to ShareCompany's THE FORUM, WISE OWL HOSTELS event space, and SOUND BAR HOWL venue rental business, addressing the same demand from event organizers, film crews, and production companies seeking distinctive Tokyo spaces.

Regional players

• Tokyu Community (東急コミュニティー株式会社): Tokyo-focused property management subsidiary of the Tokyu Group, managing thousands of condominium and rental units across Tokyo. Directly competes with ShareCompany's rental management and Zero-Yon service within the same Tokyo geography.

Emerging players

• STAY JAPAN (by Rakuten Group): Japan-focused minpaku and vacation rental booking platform (now operating under Rakuten Group). Functions as both a distribution channel partner and a competing marketplace for ShareCompany's minpaku and short-stay inventory.
