Gifu Prefecture

OOPARTSSat–Sun, Apr 11–12, Gifu Prefecture

cinema staff are artists from Gifu Prefecture. The event they host every year in their hometown of Gifu is called “OOPARTS.” It’s a two-day festival with two stages—one outdoor and one indoor—running simultaneously. In addition to the stages, there’s an official bar and a food court, making it a live event where you can enjoy music along with great food and drinks. If you get tired from all the excitement, you can take a break to refresh and then dive back in, so there’s never a dull moment throughout the day. This live event is especially recommended for those who want to enjoy performances by a variety of artists at their own pace.
