History of Noboribesu Onsen



Etymology of Noboribetsu

It is said that the name ‘Noboribetsu’ comes from an Ainu word ” Nupurupetsu”, meaning: ” The white, muddy river” or ” The thick colored river”. We can imagine ancient times when the river color was changed by the abundant flowing up of the hot springs.

Moreover, the name of the river that flows next to the onsen street comes from the Ainu word “Kusurisampetsu”, meaning: “Medicated hot water that flows to the ocean”. “Kusuri” is “hot spring2 in Ainu. The Ainu people also seem to have found the hot spring useful as a health treatment since ancient times.

Noboribetsu as a hot spring resort

In 1845, Takeshiro Matsuura, the godfather of Hokkaido, also visited Noboribetsu Onsen, and wrote a commemorative charm. At that time there was no road, so Omi’s merchant Hanbei Okada started excavation of a road in 1875. Afterwards, Kinzo Takimoto, who is known as the father of the hot spring cure, built the first onsen hotel, created the new present day road, and built the present base for the onsen. Moreover, mining of sulfur, a by-product of the onsen, came to be added to the aegis policy.

Development of Noboribetsu Onsen

Later on, Noboribetsu was designated as a health resort for injured soldiers of the Russo-Japanese War. Many Ryokans (Japanese-style inns) and souvenir shops were built and the base of the onsen street we can see today was formed.

A further improvment was later done in respect to traffic as foot and wagon travel by road was replaced by rail. In 1915, the first railways were built and wagons began to run on the tracks. In 1918, Steam locomotives were introduced, and in 1925 electric trains began to be used.

Because the trains and private homes received their supply of electricity from the same power plant, it is said that when a great number of people took the train, the house lights would flicker. At these times residents would know that: “Many visitors have come today”.

In this wat the number of people visiting Noboribetsu onsen has continued to increase, and Noboribetsu onsen has developed along with them.

The onsens naturally produce 10,000t of hot water per day, The fountain temperatures rise as high as 45 to 90 ℃., and 9 different kinds of onsen water are produced.

This is so unique in the world that the area has been nicknamed a “hot spring paradise”.

Since ancient times the onsen waters have been used as a therapeutic bath to cure disease and injury, and in recent years, many people are realizing their benefits and those in good health are enjoying onsen for refreshment of mind and body.
