The Hokkai Heso Matsuri centers around the Hokushin Shrine, which honors the belly button and serves as a place for prayers related to birth, love, life, growth, peace, thriving, happiness, and health. This shrine is a significant focal point of the festival, embodying the spirit of the celebration.
One of the highlights of the festival is the Hokkai Belly Dance Competition, where an impressive 4,000 dancers compete over two days in the vibrant streets of Furano.
