University of Tokyo, Komaba Research Campus
Institute of Industrial Science (IIS)
4 Chome-6-1 Komaba, Meguro-ku, Tōkyō-to 153-0041
2nd floor of the An-Block
The campus is approached either from the Komaba-Todaimae station on the Keio-Inokashira line (5min from Shibuya) by 10min walk, or from the Yoyogi-Uehara on the Odakyu and subway Chiyoda lines by 15 min. walk. See the access map here People can find a hotel along these lines.
The venue is in a quiet residential area, and there is no hotel in a walking distance (Maybe one, but not popular). Therefore, we would suggest you book a hotel in Shinjyuku or Shibuya area which is a big terminal in the downtown Tokyo. You can take a public train from these terminals to the stations close to the venue (See the access map), and that will take just 10~15min.
You can find many hotels in the hotel booking sites. If you are familiar with Tokyo, you may find a hotel in other areas.
There is the U. Tokyo Komaba campus just in front of the station, but, be careful it is not the workshop site. It is the U. Tokyo Komaba "Research" campus where the workshop is held, and is within 10min. walk from the station.
