1. Explore The Temples At Nikko
Nikko is a mountain town a few hours north of Tokyo filled with UNESCO World Heritage temples that should not be missed by any religious or respectful person to all religions. Many people do it as a day trip but it's worth your time to stay overnight to get an early start and avoid the crowds.
The main attraction here is the Toshogu Shrine, which has more than a dozen luxuriously decorated red-and-gold buildings among huge, ancient cedar trees. Atmospheric Futarasan-jinja is worth a look for games, while the mountain hike up to the tranquil Takino shrine is recommended.
