Insider tip — Yu no Sato serves Hashimoto City, the northern gateway to Koyasan on the Nankai Koya Line railway where pilgrims have ascended to the mountain monastery of Kukai (Kobo Daishi) since the 9th century. Hashimoto sits at the confluence of the Kinokawa River and the ancient Koya-kaido pilgrimage highway, and the city preserved the old post-town character of the road that once served the endless stream of devotees climbing to the sacred mountain monastery that remains Japan most visited pilgrimage site with over a million visitors annually.
