We do not have conference special discount rate hotels and on-campus accommodations.

There are many hotels within a reasonable distance from the conference venue.
We share an example list of hotels around the conference venue. More accommodation may be found through services like Expedia and, with keyword "Takebashi station" or "Jimbocho station".

A bit further away are a greater number of options. For these hotels, you will need to take the metro. The conference venue is near two Metro stations Takebashi (T08) and Jimbocho (S06, I10, Z07) intersecting with four Metro lines. The metro in Tokyo is efficient and easy to navigate. A Subway Map in English and other languages is available for download. Below is a list of hotels near metro stops that are easy to reach from the conference venue:
