Although the natural world provides countless wonders, hot springs, whose healing waters have comforted humans from time immemorial, hold a special place in the hearts of the Japanese. Despite being such a small country, Japan has more than 3,000 hot springs, making it one of the most onsen-rich countries in the world. In addition to the healing power of the hot springs themselves, the effect of going to a place where one is surrounded by abundant nature is also significant. Having said that, you should be careful not to soak in an onsen too long because “it feels good,” as the heat can tire you out. You should limit the time in the water by, for example, visiting the onsen once on the day of arrival and once the next morning, or reducing the duration of each bath. There is a Japanese adage that one should “keep the head cold and the feet warm.” We hope that you will take advantage of open-air baths where you can enjoy a soak while achieving this ideal of keeping the head cool and the body warm. From among the numerous famous onsen of Japan, in this article we introduce hot springs of Hakone and Izu, which are within 2 hours-travel from the Japanese capital, Tokyo, by train or car. These hot springs have been beloved by Tokyo residents from days of old as easily-accessible holiday destinations. While there are many handy accommodations to choose from, it pays to be a little picky and select lodgings to fully enjoy your precious holiday onsen trip. We carefully selected lodgings that promise, based not only on the onsen, but also meals and rooms, to satisfy all five of your senses and to make your stay a special one. Through these superb lodgings in Hakone and Izu, we would like you to experience onsen, which have been so valued and beloved by the Japanese people.
