Nikko National Park

The official mausoleum of dynasty founder Tokugawa Ieyasu and the most extravagant temple in Nikko, constructed in 1634 on the order of his grandson Iemitsu, though not his actual resting place. The shrine took 2 years to complete with the efforts of 15,000 workers. Although the surrounding shrine is very ornate, the tomb itself is surprisingly simple and unassuming. While it had been believed that Tokugawa Ieyasu's body was moved here from Kunōzan Tōshō-gū in Shizuoka following its completion, 21st-century research has revealed that his body was never moved here and remains in Shizuoka.

Iemitsu, the 3rd Tokugawa Shogun and grandson of Ieyasu, is buried here. Smaller, although much more beautiful than Tōshōgū. The main hall and mausoleum can only be viewed from outside. Unlike Tōshōgū, the tomb is not accessible to the public.

A small museum of artifacts related to Tōshōgū and the Tokugawa dynasty. The introductory video is quite good, and the fascinating half-Japanese, half-Western suit of armor that Ieyasu is said to have worn at the Battle of Sekigahara is worth a look, but the rest of the exhibits are a bit lackluster: old scrolls, swords and knickknacks. The cafe is a nice place for a break though. Tickets can be bought in combination with the shrine or separately.

Founded by Shodo Shonin, the monk that introduced Buddhism to Nikko in the 8th century. Known for its three large Buddha figures (at the Sanbutsudoh Hall portion of Rinnoji Temple) and for the beautiful and peaceful Shōyō-en Garden (逍遥園), the entrance price allows you to see one of the three Buddhas and the renovation works.

This much-photographed red bridge separates the shrines from the town of Nikko. In feudal times, only the shogun was permitted to cross the bridge, and even today it's barred from pedestrian traffic — although there's a 4-lane highway rumbling right past. You can get a nice view from the sidewalk, but to set foot on the bridge and look down into the gorge below, you'll have to buy a ¥350 ticket from the booth nearby.

This often overlooked mountain shrine is situated slightly up the mountain behind Toshogu and provides a welcome relief from the more crowded areas of Sannai. It takes its name from the picturesque waterfall that greets you at the base of the entrance. You can get there by walking for about 15-20 minutes along an ancient and atmospheric stone path that begins behind the Toshogu Shamusho (office). This path also features several other notable sites such as the Kyosha-do Hall (Japanese Chess pieces are left here as offerings for hopes of a safe birth), the worship hall Kaisan-do and the gravesite of Shodo-Shonin (the latter two are maintained by Rinnoji Temple).
