Mercury Develops Single-Occupant Rental Apartment in Oshiage

Mercury Inc. is developing "Mercury Oshiage," a rental apartment building in Bunka 1-chome, Sumida Ward, Tokyo. Construction began in February 2026, with completion scheduled for the end of February 2027.

The property is located a 10-minute walk east of Oshiage Station. While the area around the station is home to tourist and commercial hubs such as Tokyo Skytree and Solamachi, the property itself is surrounded by a quiet residential neighborhood. The building rises five stories above ground, with a total exclusive floor area of 184 tsubo (approx. 6,500 sq. ft.). Units are configured as 1DK and 1LDK layouts of approximately 30 to 33 sq. m (approx. 300 to 400 sq. ft.).

According to the Sumida Ward Population Vision (formulated in March 2025), the ward has continuously seen net in-migration since 2004. 2023 and 2024 marked the largest net in-migration for the period, driven primarily by a significant inflow of people in their 20s. Amid this continued inflow of younger residents, the average asking rent for 1DK/1LDK rental apartments within a 10-minute walk of Oshiage Station has risen approximately 34% over the past five years, according to estie Residential Research, reaching around JPY 15,800 per tsubo currently. The company also broke ground in January 2026 on an all-1LDK rental apartment building in Ryogoku (see related article: Mercury Launches "Mercury Ryogoku" Rental Apartment Development in Sumida Ward), and this project appears aimed, together with that one, at capturing demand for single-occupant rentals in Sumida Ward.
