What （株）エスティア does
株式会社エスティア (Estia Co., Ltd.) is a privately held Japanese real estate investment company founded in 1992 (originally as 株式会社ランド・ビー, renamed in 2004) and headquartered in Minato-ku, Tokyo. The company develops, sells, and manages studio-type investment condominiums (one-room mansions) under its proprietary PLOPF Series brand across approximately 16 locations in the Tokyo metropolitan area and Kanagawa Prefecture, targeting middle-income salary earners, OLs, and civil servants seeking long-term passive income and retirement preparation rather than speculative gains.
The core business is vertically integrated: in-house development feeds direct sales to individual investors, while wholly-owned subsidiary 株式会社エステートナビ (Estate Navi, established 2001) handles ongoing rental management, tenant acquisition, rent collection, and maintenance. Estia operates a web-based owner portal called PORT for asset management and long-term financial simulation, an Owner's Club for owner communications, and distributes a free PDF real estate investment guide for lead generation. In 2021 the company launched ONEBOX, a consulting and events service focused on one-room mansion investment customers. Supporting infrastructure includes the Owner Site, free individual consultations, online seminars, and outbound telephone sales as the primary customer acquisition channel.
The revenue model combines one-time property sales (license-style) with a managed rental services stream that charges a 5% take rate on rent collected (家主集金代行システム) and operates an 90% lending system (借上システム) that guarantees stable rental income to owners. The company maintains lending relationships with major Japanese banks including Mizuho, MUFG, Resona, and Sumitomo Mitsui, and is a member of the 首都圏中高層住宅協会 industry association. The company is led by founder and Representative Director President 鶴巻通雄 (Michio Tsurumaki), has 11 employees, and reported paid-in capital of 50 million yen as of 2018.
