Hankyu Hanshin Properties To Develop Its First Soundproof Rental Apartments in Nerima and Adachi

Hankyu Hanshin Properties announced on November 11, 2026, that it will develop two soundproof rental apartment buildings, its first, in Toyotamakami 1-chome, Nerima-ku, and Senju-Nakacho, Adachi-ku, Tokyo. The first, GEO ENT Ekoda Sound, is scheduled for completion in December 2026, and the second, GEO ENT Kita-Senju Sound, in August 2027.

GEO ENT Ekoda Sound is a three-minute walk from Ekoda Station on the Seibu Ikebukuro Line, and GEO ENT Kita-Senju Sound is a six-minute walk from Kita-Senju Station. Both are 12-story buildings with 33 units each, in 1K, 2K and 2DK layouts.

Each unit has a soundproof room and adopts a floating construction method that creates a floating floor independent of the structural slab. Sound insulation class D-55 is set as the minimum guaranteed value. The buildings will also have large elevators designed to accommodate the delivery of grand pianos.

Other companies are also developing soundproof rental apartments that respond to diversifying lifestyles involving sound, such as playing musical instruments, video streaming and telework. JR West Real Estate & Development's J.GRAN Court Nakano was completed in May 2026, and in the same Toyotamakami 1-chome, Livlan's MUSISSION with Ekoda was completed in September 2026. In addition, Sogo Housing is developing a project in Hasunuma-cho, Itabashi-ku, and Tokyo Tatemono in Izumi, Suginami-ku.
