What INTELLEX does

INTELLEX (株式会社インテリックス) is a Tokyo-headquartered, publicly listed Japanese real estate company founded in July 1995 that acquires, renovates, and resells used condominiums under its flagship Renovex Mansion brand. The company serves individual homebuyers, individual sellers, senior homeowners, real estate investors, and corporate clients across Japan through a vertically integrated platform that covers direct property purchase, brokerage with a purchase guarantee, a leaseback service ("Anbai"), fractional real estate ownership ("Asset Sharing"), and ongoing property management. In December 2025, Intellex reorganized under a new holding company, Intellex Holdings Co., Ltd., consolidating six wholly owned operating subsidiaries — Intellex Kukan Sekkei (design and construction), Intellex Property (asset and building management), FLIE (online real estate marketplace), Recosis (energy-saving renovation technology and franchise), Saisei Jutaku Partner (partner-company consulting), and Intellex Kobe Minato (Kansai regional operations). Operations span eight major Japanese regions from Hokkaido to Kyushu.

The company's core product is the Renovex Mansion — a quality-assured renovated condominium subject to approximately 300 inspection points and backed by an up to 20-year after-sales warranty, with each unit accompanied by a disclosed housing history (住宅履歴). The underlying renovation methodology integrates proprietary energy-efficiency systems under the EcoCube brand, combining resin-framed double-pane interior windows, high-performance insulation, and heat-exchange ventilation that reduces air-conditioning electricity costs by approximately ¥800/month versus standard renovations. Intellex has ranked in the top three nationally for R-Housing (適合R住宅) certification issuance for six consecutive years through 2026, including #1 for three consecutive years (2020-2022), and reports a 98.7% after-sales satisfaction rate. The company has cumulatively sold more than 28,000 renovated condominium units (May 2025), completed 1,000+ renovation projects annually, and acquired more than 20,000 properties through direct purchase.

Intellex generates revenue across multiple streams: spread-based income on renovated condominium resale (the core), brokerage commissions, recurring rental income from the Anbai leaseback, asset sharing management fees, property management fees, and renovation design and construction services. Pricing is transaction-based and individually quoted rather than standardized. The company distributes through a multi-channel approach combining direct field sales, web inquiry forms, the FLIE online portal, listings on third-party real estate marketplaces (SUUMO, HOMES), the IntellexCLUB premium membership referral network, leaseback partner stores, and the Aoyama Renovation Studio showroom. The company was listed on the Tokyo Stock Exchange in 2005 and completed a stock transfer into Intellex Holdings in December 2025.

Revenue model

1. Renovated Condominium Sales (リノヴェックスマンション): Intellex acquires used condominiums, renovates them through its subsidiary Intellex Space Design, and sells them to individual buyers. Revenue is generated from the spread between acquisition/renovation cost and sale price. This is the core business generating the majority of company revenue.
2. Direct Property Purchase (直接買取): Intellex directly purchases properties from sellers at a discounted price, renovates them, and resells. The company earns revenue from the value-added spread. Key differentiator is no intermediary commission for sellers.
3. Brokerage / Intermediary Services (仲介): Intellex acts as a broker connecting property sellers with buyers through its IntellexCLUB member network. Earns brokerage commissions (typically 3%+¥60,000 for properties over ¥4M) with a purchase guarantee option.
4. Leaseback Services (リースバック「あんばい」): Intellex purchases properties from owners who then rent them back. Revenue is generated from rental income over the long term, supplemented by eventual resale of the property after tenant departure.
5. Renovation Design & Construction (リノベーション): Intellex Space Design provides renovation design and construction services for both third-party clients and Intellex's own inventory. Revenue from renovation fees charged to corporate clients and individual home renovation customers.
6. Asset Sharing / Real Estate Fractionalization (不動産小口化商品): Intellex Property manages fractional real estate ownership products, generating ongoing management fees from co-owners.
7. Property Management (不動産管理): Building management services for properties owned by Intellex or managed on behalf of third parties.

Scale indicators9 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Tokyu Land Corporation (東急不動産): Large diversified Japanese real estate developer active in residential development, urban redevelopment, and real estate services. Operates in adjacent spaces where Intellex's renovation and resale offerings compete for similar customer segments.
• Daiwa House Industry (大和ハウス工業): Major Japanese homebuilder and real estate company with single-family housing, condominium development, and lifestyle services. Potential competitor in the broader renovation/resale ecosystem with significantly greater capital resources.
• Mitsui Fudosan (三井不動産): Japan's largest real estate developer with comprehensive residential development, brokerage, and property management. While not a renovation specialist, its scale and existing developer relationships pose a competitive threat if it expands into used condo renovation.
• Mitsubishi Estate (三菱地所): Premier Japanese real estate developer focused on office buildings, commercial properties, and residential developments including premium condominiums. Could expand into used condo renovation given its scale and brand strength in Tokyo.

Direct peers

• GA Technologies: Japanese real estate technology company operating the RENOSY platform, which bundles used condominium acquisition, renovation, and resale services. Competes directly with Intellex in the tech-enabled used condo renovation space.
• Property Agent (株式会社プロパスト): Tokyo-based real estate company that acquires used condominiums, renovates them, and resells — closely paralleling Intellex's Renovex Mansion model. Direct competition in the same acquire-renovate-resell niche targeting individual Japanese condominium buyers.
• Housmart (ハウスマート): Japanese used condominium marketplace and renovation service provider with similar focus on data transparency, housing history disclosure, and buyer education — overlapping with Intellex's content marketing and quality-positioned strategy.
• Renoveru (リノべる): Japanese renovation company specializing in middle-renovation of used condominiums with design-led positioning. Competes for the same buyer demographic seeking quality-assured renovated apartments in urban Japanese markets.

Emerging players

• Open House Group (オープンハウスグループ): Japanese real estate developer specializing in single-family homes and condominiums in the Tokyo metropolitan area, with growing presence in the used property and renovation segments — representing an emerging competitive force in Intellex's core market.

Regional players

• Pressance Corporation (プレサンスコーポレーション): Mid-cap Japanese condominium developer with strong presence in Kansai and other regional urban markets. Competes for similar urban condominium buyer demographics in select geographies where Intellex operates.
