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.
Sanada Yukimura's story runs from Ueda Castle to exile in Kudoyama and a last stand at Osaka Castle, Sanada Maru and Tennōji. He held Ueda against a far larger Tokugawa army in 1600, then died in 1615.
The route follows him from the Sekigahara campaign through exile below Mount Kōya to the Winter and Summer sieges of Osaka. Some sites are marked approximately, because the sources do not give exact spots.
In the autumn of 1600 two armies met at Sekigahara to decide who would hold power after Toyotomi Hideyoshi. One day in the fog gave Tokugawa Ieyasu a decisive victory and put him on the road to the shogunate.
The route follows the campaign from the siege of Fushimi to the castles of Mino, the field of Sekigahara, the fall of Mitsunari's Sawayama and his burial in Kyoto, and ends at Edo Castle in 1603. Dates inside Japan's old calendar are labelled as such.
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.
In 1581 the African slave Diogo comes to Kyoto with a Jesuit delegation and is handed to the warlord Oda Nobunaga, who renames him Yasuke and makes him a samurai. That year Nobunaga's army crushes the ninja province of Iga, where the young shinobi Naoe loses her father and inherits his Hidden Blade.
From there the two hunt the same conspiracy across Kansai: the port of Sakai, the temple at Honnō-ji where Nobunaga dies, a kofun in Settsu, the castle of Shōryūji at Yamazaki, the shrines of Yamato, and the Templar recruiting ground of Kii. Most stops are real castles, temples and tombs that the game rebuilds.
