Area guide

Nasu Onsen is located on the border of Fukushima Prefecture, the northernmost part of Tochigi Prefecture, about 180 km from Tokyo.

The plateau that spreads at the foot of the vast mountain range of Mt. Chausu, the main peak of the Nasu mountain range, the only active volcano in Tochigi Prefecture that is still active, is called Nasu Kogen, and it is a Onsen resort that collectively refers to the 11 Onsen resorts scattered in this wide area.

The famous "Nasu Seven Onsens" are the seven springs of Shika-no-yu, Kaohsiung, Hachiman, Benten, Kita, Daimaru, and Santo-ya, to which Asahi, Iimori, Guo Gong, and Daimaru were added, and are now called "Nasu Eleven-yu".

Since the climate of Nasu Kogen is cool and comfortable in summer, development as a summer resort and resort area is progressing, and there are many villas and hotels, and there are many leisure facilities for guests.

In fact, this Nasu Kogen is located in Nikko National Park, and the beautiful scenery of the four changing seasons is one of the highlights. In 2011, the Ministry of the Environment took over a part of the forest in the Imperial Residence and opened it to the public as the "Nasu Heisei Forest", so that you can enjoy the rich nature even more.

Nasu Onsen uses a spring that springs from the vast foot of Mt. Chausu, the main peak of the Nasu Federation, which is the only active mountain in Tochigi Prefecture. Mt. Chausu is said to be the last mountain formed by the Nasu Volcanic Belt, and its altitude is 1,915 m, and it still boasts a spring water volume of more than 9,000 liters per minute while emitting white plumes, ranking ninth in Japan.

The history of Nasu Onsen is long, and it is said that it was discovered about 1390 years ago by Saburo Kano Yukihiro, a county priest in this area, while hunting deer.

According to tradition, when Saburo Yukihiro Kano chased a white deer that had failed to shoot and went into a deep valley, a white-haired old man who claimed to be the god of Onsens appeared, and when he searched for the deer according to his advice, he found a deer that was soaking in the Onsen and healing the wound of the arrow. It is said that Saburo Kano named the Onsen "Shika-no-yu" and built the Onsen forest (now Nasu Onsen Shrine) and dedicated the deer antler that was shot.

The "Shika-no-yu" opened in this way is the 32nd oldest Onsen discovery in Japan, and the oldest in Tochigi Prefecture after Shiobara and Nikko. Along with the same Kanto Onsen resorts, Atami, Shushoji, Kusatsu, Ikaho, etc., it has long been known throughout the country as a famous Onsen in Japan with a long history and has continued to heal many Onsen guests.

In the Shōsōin document "Suruga Kokusho Tax Book" written in the Nara period, there is a description that Ono Asomi accompanied 12 of his followers to Nasu Onsen for Onsen treatment, and it can be seen that Nasu Onsen was already known to the capital of Nara and was used as a Onsen resort.

Since then, there have been descriptions of celebrities visiting in numerous literatures, and it seems that they have continued to heal the people of Ooku. In the Edo period, the roads were improved, the common people began to rub the sound, and the Onsen area expanded.

By that time, Onsens had already been discovered one after another, following "Itamuro", "Santoya", "Daimaru", "Kita", "Benten", "Kaohsiung" and "Shikanoyu", and it seems that they were called "Nasu Nanayu".

After the Meiji era, "Hachiman" was discovered, and in the Taisho period, "Asahi", "Iimori", and "Guo Gong" were discovered, and "Shin Nasu", which is a reference to the spring water of "Daimaru", was added to the Nasu Jujiyu, but now it is mainstream to call it Nasu 11 Yu, except for Itamuro, which is somewhat geographically far away.

After the war, with the opening of the Tohoku Expressway and the Tohoku Shinkansen, it began to gain popularity as a vacation home area, and accommodation facilities such as dormitories, recreational facilities, and pensions increased.

Along with this, the number of recreational and tourist facilities such as theme parks increased, and the demand for Onsens increased even more, and it developed into the "international tourist destination Nasu" that it is today.
