Koyasan, a sacred place opened by Kobo Daishi Kukai, has been gathering the faith of many people for about 1200 years. The highway for visiting Koyasan has been gradually improved since the Heian era, and several highways in Osaka Prefecture merged near Kawachinagano, and eventually became known as the “Koya Highway.” During the Edo period, the Koyasan pilgrimage became a big boom, and a post town was formed along the way, and it became the standard practice to give the various kinds of rice balls, steamed buns and rice cakes to the pilgrims.

弘法大師空海が開いた霊場高野山は、現在に至るまで約1200年間、多くの人達の信仰を集め続けています。高野山参りの街道は平安時代以来徐々に整備され、大阪府下にいくつもあった街道が河内長野付近でひとつに合流し、いつしか「高野街道」と呼ばれるようになりました。江戸時代には高野山詣りは一大ブームになり、道中には宿場町が形成され、村々でおにぎりやお饅頭、お餅などさまざまな施しをいただきながら参詣することが定番になりました。
