A little dress code fyi for when you visit Koyasan.
Be comfortable, but be aware of dress code norms observed by this World Heritage pilgrimage site.
Authorities at the sacred Koyasan pilgrimage site in Wakayama Prefecture are requesting that visitors refrain from wearing revealing clothing as the summer season approaches. Kongobuji Temple, the head of the Shingon Sect, recently installed signs and began distributing leaflets at the entrance to the sacred Okunoin area to outline proper attire. The initiative targets a growing number of domestic and international tourists who may be unfamiliar with the traditional etiquette of one of Japan’s most revered Buddhist centers.
Temple officials emphasized that the goal is not to restrict access but to encourage a mindset of respect and preserve the site's spiritual dignity. While the mountain remains open to everyone, staff indicated they may respond more firmly in the future if a visitor's clothing is deemed significantly inappropriate. This move highlights the ongoing challenge of balancing Japan’s booming tourism industry with the preservation of cultural and religious norms.
