During the festival of Yuki Akari no Michi, it's normal to put in Otaru seize other "tourist traction" as the Ice Bar. The first time I saw this I knew I had to be in Japan. The bar was nice, but the ceiling was a tent, the rest, the tables, the walls, the bar shelves for bottles ... everything was made from blocks of ice! And there was much attention to detail. A worthwhile visit at least because it is quite curious.
