Open House Real Estate Acquires “b'CASA OMORI KAIGAN” in Tokyo’s Ota Ward

Open House Real Estate has acquired the rental apartment building b'CASA OMORI KAIGAN, located in Omori Honcho 1-chome, Ota Ward. The seller, R-Remix Inc. (Yokohama), originally purchased the asset from an individual in September 2022, making this a resale within roughly three years.

The property is a 3-minute walk from Keikyu Main Line Omori Kaigan Station. Built in March 2011, the five-story steel-structure building has a Gross Floor Area of approx. 109 tsubo (approx. 3,600 sq. ft.) and is composed of units designed for single tenants. The rental market for single-occupancy units around Omori Kaigan remains strong: average asking rents for 20–30 sqm units built 10–17 years ago have risen from the JPY 13,000-per-tsubo range in 2021 to the mid-JPY 16,000 range in 2025. Occupancies have held at a stable 95–97%, and properties within walking distance of the station continue to capture demand (based on estie residential research).

Open House Real Estate is a wholly owned subsidiary of the Open House Group, specializing in the acquisition, value-add, and resale of income-producing properties. Amid tighter lending standards among financial institutions, the group has been increasingly selective with investments. This asset’s proximity to the station and consistently high occupancy appear to have been key factors behind the acquisition decision.
