While Kris worked, I took a day tour to Nikko. We took the hairpin turns of Irohazaka to reach Nikko National Park, enjoy lunch overlooking Lake Chuzen-ji, visit the splendid Kegon falls, and marvel at the shrines.
Tokugawa Iemitsu built the Taiyuin-byo Shrine (1653) for his own mausoleum and the Tosho-gu Shrine (1634) for the mausoleum of his grandfather Tokugawa Ieyasur. His intent (successful!) was to impress upon any rivals the wealth and power of the Tokugawa family.
