When in Japan, you gotta check out an onsen (hot spring). We bought 2-day Hakone Freepasses and took a Romance Car to Hakone, which is close by to Tokyo. Romance, in this sense, means “adventure.” It’s an additional surcharge on top of the cost of the pass, but it’s an express train and has spacious seats, food + drinks on board, and large windows. We got a bunch of nice views of the areas outside the city. Remember to reserve your seats early so you can sit in the front or rear observation decks of the train.
