London, Los Angeles, Sao Paulo. There is little at first sight that seems to unite these three cities, which are diverse in geography and climate as well as architecture, cuisine and atmosphere.

Yet these metropolitan hubs will soon be connected by one unexpectedly common thread — the launch of an ambitious new global project that celebrates all things Japanese.

Japan House — an initiative developed by the Ministry of Foreign Affairs and creatively directed by Muji art director Kenya Hara — involves the opening of buildings in each of these three cities celebrating the best of Japanese culture, from architecture and design to food and fashion.
