A Hotel, Offices, and Residences Stacked Above Toranomon

Tokyo World Gate (Kamiyacho Trust Tower) was completed in March 2020 on a site in Toranomon 4-chome, Minato City. The tower rises 38 floors above ground and three below, reaching approximately 180 metres. The project was developed by Mori Trust, designed and built by Shimizu Corporation in collaboration with Yasui Architects & Engineers. Hotel and lobby interior design was handled by Kengo Kuma and Associates. The building connects directly to Kamiyacho Station on the Tokyo Metro Hibiya Line via an underground passage.

The programme is layered vertically: floors 3 through 30 are office space, floors 31 through 36 house the Tokyo Edition Toranomon — a luxury hotel in the Marriott portfolio — and floors 37 and 38 are residential units. This kind of stacked mixed-use configuration remains relatively uncommon in Tokyo’s large-scale redevelopments. The Kengo Kuma-designed interiors draw on timber and greenery throughout the hotel floors and lobby, creating an atmosphere distinct from a conventional office tower.

A Site Transformed by Toranomon’s Redevelopment Wave

The tower occupies the former site of the Tokyo Norin Nenkin Kaikan (Toranomon Pastoral). Its redevelopment was backed by a national strategic special zone designation. The broader Toranomon–Kamiyacho corridor has changed rapidly, with the Mori Building-led Toranomon Hills complex adding successive towers alongside this Mori Trust project — a Business Tower in 2020 and a Station Tower in 2023 — steadily replacing what was once an unremarkable stretch between Kasumigaseki and Roppongi.

The building’s original working name, Kamiyacho Trust Tower, was unified under the umbrella brand Tokyo World Gate after completion. Arriving via the underground passage from Kamiyacho Station and emerging into the plaza at the building’s base, the glass facades of neighbouring towers come into view — a reminder of how densely this corner of Tokyo has been rebuilt in just a decade.

Summary

Tokyo World Gate completed in March 2020 with 38 floors and a height of approximately 180 metres. Its mixed programme of offices, the Tokyo Edition Toranomon hotel with Kengo Kuma interiors, and residences makes it one of the more complete examples of the vertical mixed-use typology now taking hold in central Tokyo. The underground connection from Kamiyacho Station to the tower’s lobby is the most direct way to arrive — from there, a short walk places you at the centre of one of the city’s most active redevelopment zones.
