A New District Rising Before Yotsuya Station

Yotsuya Station occupies a peculiar geographic crossroads: three wards — Shinjuku, Chiyoda, and Minato — meet nearby, and the station connects Tokyo’s inner ring to the JR Chuo Main Line and the Tokyo Metro Marunouchi and Namboku lines. It has long been a transit node, but a gap in the urban fabric sat right in front of it. That gap closed in January 2020 when CO·MO·RE YOTSUYA opened — a mixed-use complex anchored by YOTSUYA TOWER, a 31-floor, three-basement-level office building standing roughly 145 m tall, with a total floor area of approximately 139,593 m².

From National Land to Living District

The site belonged to the Japan National Railway Settlement Corporation, heir to assets left when the old JNR was broken up in 1987. It took decades to assemble a plan for the land, but the Urban Renaissance Agency ultimately led the redevelopment with Mitsubishi Estate as its business partner — a pairing that combined public-sector coordination with private-sector design and leasing expertise.

The project name CO·MO·RE is built from three Japanese verbs: kuru (来る, to come), moru (盛る, to fill), and tsureru (連れる, to bring along) — a declaration that the complex intends to draw people to Yotsuya and keep them there. Below the tower, retail floors carry cafes, restaurants, and daily-service shops, turning a former blank lot into a neighbourhood hub. Office floors offer column-free layouts and are close enough to both Shinjuku and the government-dense Chiyoda corridor to attract tenants from both directions.

Summary

CO·MO·RE YOTSUYA (YOTSUYA TOWER), completed in January 2020, brings 31 floors and roughly 145 m of office-led mixed use to a station forecourt that long sat underused. Developed by the Urban Renaissance Agency with Mitsubishi Estate, it transforms former national railway land into a dense, walkable precinct. For those exploring the less-photographed side of central Tokyo, Yotsuya offers an unexpected blend of old Catholic schools, castle moats, and now a gleaming tower courtyard.
