Toshogu Shrine is one of Japan's most popular destinations for tourists. Five structures at Nikko are categorized as National Treasures of Japan, and three more as Important Cultural Properties. The second shogun Hidetada ordered the construction of the Nikko Toshogu Shrine. Later, the third shogun Iemitsu had the shrine enlarged and lavishly decorated. Yomeimon Gate is the highlight of the shrine, far more lavishly decorative than the usual austere shrines in Japan.
