Nikko also was involved with chaos of warring states period in the 16th century. Hideyoshi Toyotomi confiscated feudal estate in Nikko because religious followers of Nikko participated in the Hojo family against Hideyoshi.

However, Bishop Tenkai revived Nikko later. He was an advisor of Tokugawa shogunate, and gave a strong influence to the establishment of Toshogu Shrine.

By the way, there is an interesting legend regarding Bishop Tenaki. According to the legend, he was Mitsuhide Akechi, who betrayed Nobunaga Oda in Honnoji temple, and escaped from chaser later. Then Mitsuhide became Bishop and renamed as Tenkai. Also, Bishop Tenkai wanted to leave his real name, and named it for the best landscape in Nikko. That is Akechi-daira plateau today.
