Star Mica

What Star Mica does

Star Mica Co., Ltd. (スター・マイカ株式会社) is a Japan-based renovation condominium company founded in 2001 and headquartered in Tokyo. It operates as the core operating subsidiary of STARMICA HOLDINGS Co., Ltd. (TSE Prime Market, code 2975), a holding company structure established in 2019. Star Mica's business model is structured around purchasing used condominiums in Japan, including tenant-occupied (owner-change) properties that other buyers cannot easily acquire, holding them through the tenancy period via its property management subsidiary STARMICA Property, renovating them once vacant, and reselling to individual consumers through a nationwide office network and its brokerage subsidiary STARMICA Residence. The company also operates adjacent investor- and asset-management services through STARMICA Asset Partners and STARMICA Asset Management.

The company has cumulatively acquired more than 19,000 used condominium units (approximately 1,600 per year) and sold over 15,000 renovated units, supported by an internal appraisal database of approximately 280,000 records. It has held the No. 1 position in Japanese used condominium holdings since 2013 and was again ranked No. 1 in the 2025 repurchased-and-resold used condominium sales volume ranking by Reform Industry Newspaper. Star Mica employs 1,001-5,000 people, operates eight sales offices across Japan (Tokyo, Osaka, Yokohama, Saitama, Fukuoka, Nagoya, Sendai, Sapporo, Kobe), and owns a real estate transaction business license under Japan's Building Lots and Buildings Transaction Business Act (Ministry of Land, Infrastructure, Transport and Tourism license).

Revenue is generated primarily through one-time resale transactions of renovated condominiums, complemented by transaction-fee income on owner-change purchases and professional service fees from rental management and investor consulting. Pricing is quote-based and not publicly disclosed. The customer base is highly distributed across individual buyers and sellers, with real estate agencies acting as referral partners. The company is also diversifying through strategic partnerships, notably a March 2026 collaboration with Panasonic Housing Solutions on the 'Life Style Fit' renovation concept that integrates smart home technology and lifestyle design into its renovated properties.

Core offering

Star Mica purchases used, often tenant-occupied (owner-change) condominiums, holds them until tenants vacate, renovates them to add value, and resells the renovated units to individual consumers. The company also offers complementary real estate services through subsidiaries: brokerage (STARMICA Residence), rental management of more than 3,000 units (STARMICA Property), income-property buy/sell and rental management (STARMICA Asset Partners), and cross-asset portfolio consulting (STARMICA Asset Management).

Product overview

Star Mica operates a unified renovation condominium platform built around its core business of buying used, tenant-occupied (owner-change) condominiums, renovating them, and reselling them to end consumers. The platform integrates four sub-brands: STARMICA (core renovation condo buy/sell), STARMICA Residence (sales brokerage), STARMICA Property (rental management for ~3,000+ units held during tenant occupation), and STARMICA Asset Partners/Asset Management (investor-focused buy-sell, management, and private banking). Supporting the consumer journey, Star Mica operates two editorial media properties—しあわせリノベ研究所 (lifestyle magazine with renovation case studies and neighborhood spotlights) and URILABO (selling guidance magazine covering appraisal, tax, and area guides). The group also launched the single-building STELLA renovation series in 2010. Together, these brands enable Star Mica's unique business model of acquiring hard-to-sell occupied units, holding them through tenancy, renovating after vacancy, and delivering renovated condos at accessible prices with new-construction-level value.

• Daiwa House Industry (大和ハウス工業): Japan's largest homebuilder and a diversified real estate conglomerate. Comparable as a broad incumbent in residential real estate, though its focus skews to new construction rather than renovation resale.
• Tokyu Land Corporation (東急不動産): Major Japanese real estate developer with residential, commercial, and urban redevelopment operations. Comparable broad incumbent in Japanese real estate.
• Nomura Real Estate Holdings (野村不動産ホールディングス): Japanese real estate group with residential development (PROUD series), investment management, and brokerage. Comparable as a broad incumbent with overlap in residential and investment property markets.

Others

Emerging players
