Since April 2019, we've been continuously building a comprehensive nationwide database of condominium and apartment buildings across Japan.

As of April 2025, we’re proud to announce that our dataset has surpassed 2.7 million buildings.

Launch of “Shiireru Meibo” – an Effective Property Acquisition List Creation Service

Shiireru Meibo (シーレル名簿) helps sales teams efficiently target properties with strong demand, such as specific apartments or buildings. By pinpointing promising listings, the service enhances property acquisition efforts and streamlines outreach.

Propre Base Co., Ltd. (Headquarters: Adachi-ku, Tokyo) has launched “Shiireru Meibo” on October 15, 2024, a service that compiles lists of property owners for apartments and condominiums filtered by specific building characteristics.

This service addresses the challenges faced by property resale companies, remodeling firms, and accounting offices, which previously spent significant time manually creating property lists and researching owner information. With Shiireru Meibo, users can quickly access a list of relevant properties by simply specifying conditions like area, then obtain focused owner information only for properties of interest.

The service reduces costs by excluding unnecessary owner data, and Propre also handles tedious tasks, such as researching property numbers and applying for registry information, allowing clients to focus on sales activities. Additionally, users can opt to receive supplementary data on vacancy rates and past listing histories from Propre’s extensive real estate database.
