Kūkai (Kōbō Daishi) was born in Shikoku, studied in Xi'an and founded Shingon Buddhism at Jingo-ji, Tō-ji and Mount Kōya, where he is entombed at Okunoin.
The route follows the monk from his birthplace at Zentsū-ji to Qinglong Temple in Tang China, then back to the temples near Kyoto and the mountain retreat he asked for in 816. It ends at his mausoleum, where monks still bring him meals.
Walking the island of Shikoku from temple to temple, in the footsteps of the monk Kūkai, is one of Japan's oldest pilgrimages.
This route visits seven of the 88 temples, from Temple 1 in Tokushima to the finish at Temple 88, passing the four provinces, Kūkai's birthplace and the highest temple. The legends here are temple tradition, not proven history.
