Works in the Tokyo area
Ginza Place (2016)
The building on the corner of the Ginza 4 Intersection instantly became a major landmark in one of the most expensive areas of the entire country.
The facade features over 5,000 aluminum panels, and inside has the flagship showrooms of major Japanese brands such as Nissan (Floors 1 and 2) and Sony (Floors 4 and 5).
Daikanyama T-Site (2011)
This facility contains a big book store featuring a concierge in each section, branding themselves as a "department store-like bookstore".
Notice the hundreds of interlocking "T" letters in the facade.
Daikanyama is a stop away from Shibuya on the Tokyu Toyoko Line.
Location: 16-15 Sarugakucho, Shibuya-ku
Kashiwanoha T-Site, Chiba Pref. (2017)
Following the success of other "T-Site" projects, this facility was built in Kashiwa, Chiba Prefecture as part of a development project with the concept of a "smart city". The location is 7 minutes away from Kashiwa-no-ha Station on the Tsukuba Express Line.
Works outside of the Tokyo area
Koban, Kumamoto Station (2011)
Koban (Police boxes) can be found outside virtually every major rail station in Japan usually with a very simple, dull design.
This one outside a major rail station in the Kyushu Island looks a bit more bright and colorful.
The box was part of the "Kumamoto Artpolis" urban planning project; Toyo Ito is currently the commissioner of this project.
