One of the world’s largest cities, Tokyo is an ultramodern metropolis, rich in history and endlessly fascinating. From Shibuya District’s hip shops, to Omoide Yokocho’s narrow lanes packed with restaurants, to Shinjuku District’s skyscrapers and nightlife, Tokyo has a side suited to every taste. 

GIA in Tokyo is fittingly located in the Taito District – an area home to serene parks, ancient temples and the many luxury retailers lining Omotesando Avenue. Easily accessible by public transportation, GIA classrooms are in the same building as the GIA Laboratory in Tokyo.
