Guide
Mitsuke Tenjin Hadaka Matsuri is a historic ritual held annually at Yanahime Shrine (Mitsuke Tenjin) in Iwata City, Shizuoka Prefecture. This festival is officially designated as an Important Intangible Folk Cultural Property of Japan, highlighting its immense cultural value. The centerpiece of the ritual involves the deity Yanahime-no-Okami traveling to Omi Kunitama Shrine. Participants, known as parishioners, perform the sacred rites wearing only traditional fundoshi (loincloths), symbolizing purity and strength.
The most breathtaking sight is the sight of men gathered in fundoshi, creating an atmosphere of intense heat and energy. Historically, these 'naked festivals' serve as a ritual of purification (misogi) to wash away impurities and welcome rebirth. Witnessing the explosive vitality of the participants amidst the summer heat offers a profound look into the raw power of Japanese traditions. The area is also steeped in the legend of the sacred dog Shippei Taro, adding a layer of local folklore to your experience.
The Mitsuke Tenjin Hadaka Matsuri is typically held on the Saturday and Sunday around August 10th of the lunar calendar. In 2026, it is scheduled for August 10th. The event follows a structured progression of Shinto rituals. Please check the official website or local signage closer to the date for the specific time schedule.
