The Tokyo Foreign Studies University (Tokyo Gaigo Daigaku) in Fuchu has their ‘Gaigosai’ festival each year in mid to late November.
The student organisers promise ‘a tour around the world without the need for a passport’. Although if you would like to drink alcohol, they’re issuing an ‘alcohol passport’ – definitely sounds like more fun than a trip to immigration in Shinagawa.
First year students will be manning the stalls, while second year students will be performing foreign language plays using the language in which they are majoring.
Closest station is Tama Station on the Seibu Tamagawa Line.
