JR West Properties Completes Rental Apartment in Arakawa Ward, Tokyo

JR West Properties has completed “Predia Court Nishi-Nippori,” a newly developed rental residential property. The building was delivered on January 30, 2026. Located in Higashiogu 4-chome, Arakawa Ward, Tokyo, the property is a three-minute walk from Akado-Shogakkomae Station on the Nippori-Toneri Liner, with additional access to Tabata Station on the JR Yamanote Line and Nishi-Nippori Station on the Tokyo Metro Chiyoda Line.The property is a 14-story reinforced concrete building comprising 65 residential units. Unit layouts range from 1DK to 2LDK (31.29 to 50.49 square meters), offered in five floor plan types. Interior corridors are designed in a hotel-style configuration.JR West Properties develops the “Predia Court” rental apartment series nationwide, and this marks the 17th property in the lineup. Its development pipeline indicates a clear concentration of investment in eastern Tokyo, particularly in the Joto submarket (see related article: Rental Apartment Completed in Nishi-Kasai — JR West Properties).

The Joto submarket in eastern Tokyo has drawn increasing attention in recent years as rising land prices in the city center spill over into surrounding wards. According to Tokyo’s 2025 benchmark land price survey, residential land values rose 11.8% in Sumida Ward, 10.5% in Koto Ward and 9.9% in Arakawa Ward, approaching growth levels seen in central Tokyo. With land acquisition costs still comparatively lower than in the urban core, developers are stepping up investment from a yield perspective in rental housing projects. JR West Group’s active expansion outside its core railway service areas is viewed as a response to these favorable market conditions.
