Bathing in natural hot springs
Japan is an archipelago of volcanic origin. Several mountain ranges consist of extinct and active volcanoes, there is a lot of geothermal activity. Consequently, there are natural hot springs all over the country, the onsen. Onsen come in many varieties: from rustic pools in the middle of nature to artistic and luxurious basins in a beautifully landscaped lotus garden, from spas with various outdoor pools (rotenburo) to indoor pools surrounded by tropical plants.
The temperature and mineral composition of the spring water can vary greatly. Japanese people frequently use the onsen because of the beneficial effect of the minerals, but bathing is also seen as a soothing, social activity. Traditionally, the onsen are for common use, sometimes there are separate baths for men and women. Usually the hot water bath is completely undressed, swimwear is only allowed in a few places. If you prefer more privacy, choose to stay in a Ryokan with private onsen. Here you can relax and let all the impressions of the day pass by again.
Hakone
Hakone is famous for its onsen, but also visit the Fuji Hakone National Park where you can go up by cable car. Here you have a beautiful view over the area with Mt. Oh, Owakudani. Also taste one of Hakone's specialties, the kuro-tamago. This is a hard-boiled egg that has been cooked in the sulphur-rich hot springs. It is claimed that eating such an egg will add seven years to your life!
