Banquet will be held in the evening on the 2nd day. The place is Ishikura Sake Brewery (or called as Hakata Hyakunengura). No English page is available, sorry.
Traditional Japanese course dinner will be served. Vegetarian menu is also available.
After the last session ends, we assemble on the ground floor of the conference site and move together directly to the place by bus.
For return, please use the subway. The nearest subway stations are "Chiyokentyoguchi" (7 min walk) and "Gion" (10 min walk). Participants who stay at hotels around "Nakasu Kawabata" and "Hakata" stations might walk there. It's 15-17 min walk.
Here is a map around. A google map might be also useful.
