Koudaisai 工大祭

Institute of Science Tokyo (formerly Tokyo Tech)

Tokyo's festival season opens here, at a science university where the students' own projects are the show: lab open days, robot demos and a rocketry club, ten steps from the station. It is early October, so the weather is still warm enough to eat outside.

What it is

  • The first big university festival of Tokyo's autumn season.
  • Held by the science university formerly called Tokyo Institute of Technology.
  • Expect lab open days and robot demos next to the usual food stalls.

Highlights

  • Nobel chemistry laureate Hideki Shirakawa graduated from this university.
  • The station is right in front of the campus.

Best time to go

General tips that apply to most Tokyo university festivals.

  • Right at opening, usually 10:00: stalls are ready and lines are short.
  • On multi-day festivals, weekdays are the quietest days.
  • Saturday early afternoon is the busiest time almost everywhere.
  • Eat before 11:30 or after 13:30 to skip the lunch rush.

Suggested plan

  1. 10:00 Pick up a map at the gate. Do the popular indoor events (exhibitions, workshops, cafes) before the lines grow.
  2. 11:30 Lunch from the food stalls, ahead of the noon rush.
  3. 13:00 Watch bands, dance and theatre on the outdoor stages.
  4. 15:00 Walk the campus sights, then sort your trash at an eco-station on the way out.

Rules at the festival

  • Ask before photographing students up close.
  • No photos where signs say so.
  • Sort trash at the eco-stations: burnable, plastic, cans, PET bottles.
  • Don't bring your own alcohol. Many festivals ban it; where it is sold, buy only from the official stalls.
  • No smoking and no drones on campus.
  • Only enter rooms that are part of the festival.
