The workshop will be held at Large Seminar Room (大セミナー室 in Japanese) at the first floor of Subaru building in NAOJ Mitaka campus. The campus map is below.
The nearest train stations to the campus are Chofu station and Musashisakai station. From these stations, it takes around 20 mins by bus to get to the campus.
There are two airports in Tokyo, which are Haneda and Narita. We recommend to use Haneda but both airports have a direct bus to Chofu station.
