1,420 Units: A Neighborhood in a Single Tower

In Kachidoki 5-chome, Chuo City, a 53-story residential tower was completed in December 2016. KACHIDOKI THE TOWER stands 178.78 meters tall, with a total floor area of 161,623 square meters and approximately 1,420 residential units — a figure that places it among the largest single condominium buildings in Japan by number of homes. The project was designed jointly by Sato Sogo Keikaku and Kajima Corporation, with Kajima handling construction.

The scale of 1,420 units is not simply a record to note in passing. At that density, a single building begins to function less like a residence and more like a small neighborhood. Every aspect of the building — elevator counts, waste management facilities, management association governance — must be designed to serve a population equivalent to a small-town primary school. The planning of KACHIDOKI THE TOWER was, in this sense, as much an exercise in community design as it was in architecture.

Remaking the Urban Fabric of Kachidoki

The project was carried out as the Kachidoki 5-chome First-Type Urban Redevelopment Project, organized through a redevelopment association formed by the area’s landowners. Participating companies included Kajima Corporation, Mitsui Fudosan Residential, Mitsubishi Jisho Residence, Sumitomo Corporation, and Nomura Real Estate. The development sits within the broader transformation of Kachidoki from a district of factories and warehouses into one of Tokyo’s most concentrated waterfront residential zones.

The tower’s footprint opens toward the Sumida River to the north and Tokyo Bay to the south. In terms of commuting, the Toei Ōedo Line’s Kachidoki Station is within walking distance — a relative advantage in a waterfront zone where transit has historically been stretched thin. Completed a decade ago, the tower now sits within an evolving neighborhood that continues to change with each new project. It remains the landmark that marked a turning point in how Kachidoki presents itself to the city.

Summary

KACHIDOKI THE TOWER was completed in December 2016 in Kachidoki 5-chome, Chuo City. It rises 53 floors and approximately 179 meters, housing around 1,420 units across 161,623 square meters of floor area. Standing on the Sumida River embankment and looking south, the tower’s outline tells a compressed story of how Tokyo’s waterfront has been rebuilt, one redevelopment project at a time. A walk through the district rewards anyone curious about how a former industrial zone becomes a place where people make their homes.
