What first planning, k.k. does

First Planning, K.K. (株式会社ファーストプランニング) is a privately held real estate brokerage headquartered in Yokohama, Kanagawa, Japan. The firm operates from a single office and offers rental and sales brokerage services covering both residential and commercial properties. Its stated service area spans the Kanto region, with website references also extending to Kansai, though no branch network outside Yokohama is documented.

The business is a transaction-based brokerage. For rental transactions, revenue is generated through commissions set at one month's rent plus applicable tax per successful lease. Sales commissions follow Japanese industry conventions but are not specifically disclosed. Inventory is presented on the firm's own website (1st-plan.com), which supports mobile access, and is additionally distributed via the At Home real estate portal. A rental homepage renewal was completed in March 2022, indicating continued investment in the core listings interface.

The firm serves individual renters, buyers, tenants, landlords, and property owners rather than institutional or enterprise clients. There are no disclosed funding events, parent companies, franchise relationships, or management team bios in the source material. No AI, ML, data analytics, or proprietary technology stack is described; the operation is structured as a conventional human-mediated local brokerage with web and portal distribution.
