DEJIMA Expo is a Golden Week event held annually by Nagasaki International Television to promote regional exchange and regional revitalization, and in 2016 it was certified as the first project of the Nagasaki City Revitalization Project. The venue is Water and Greenery Park facing Nagasaki Port, where visitors can enjoy sea breezes as a variety of stages and vendor booths spread out. In addition to live music, its hallmark is a lineup that people of all ages can enjoy, including a gourmet festival and activities for children. It will be held in May 2026.
