Nikko is one of the popular destinations from Tokyo. You can visit there as a day trip. Of course if you stay there, you can visit many places in outside of Nikko city and also can enjoy the hot spring in Kinugawa Onsen too.
There are several ways to get Nikko by train. In this post, I will show you how to get there and compare a few deals.
These trains connect Shinjuku and Ikebukuro in Tokyo, and Nikko and Kinugawa-Onsen. These trains run on JR line and Tobu Railway line. That means you have to pay extra if you use JR Pass. JR Pass cover JR line portion only. But if you use JR East Passes, such as JR East Pass Nagano Niigata, Tokyo Wide Pass, JR East Pass Tohoku, both JR line and Tobu Railway lines are covered. This may be complicated for you.
