Do you know the top places to see or things to do when visiting Tochigi? The following (according to TripAdvisor) should give you a pretty good idea of what to go see during your time there.
The top of your list would probably be the World Heritage site, Nikko Toshogu Shrine. It's a beautiful place year round. It's surrounded by the lush green trees in the spring and summer, the golden autumn leaves later in the year, and finally covered in a thin coating of snow in the winter. Only about 2 hours from Tokyo, it's a perfect place for a day trip.
