April 24th, 2015

Shimo-osobetsu Onsen

Shimo-osobetsu Onsen is a hot spring place in Shibecha town located in the northern part of Kushiro city. Only Ajikoen (味幸園) is built in Osobetsu plain (オソツベツ原野) beside the northern tip of Kushiro-Shitsugen Wetland (釧路湿原), and is about 1 km away from Mashu National Route (National Route 391). Unfortunately, restraunts, cafes, cafes, souvenir shops and convenience stores are not built around the building.

As for the Shimo-osobetsu Onsen, simple alkaline spring with moor hot spring are gushed out. The moor spring is brown spring that gushes out from a peat bed or a lignitic bed, and contains a lot of organics of plant origin, so it has slippery touch, and is good for a skin, and is called beauty hot spring (美人の湯), too. The moor spring is different from usual types of the hot springs, and the hot springs are recognized as the moor spring if those contain humus. Hokkaido Shimbun introduced that sodium chloride spring turned into simple alkaline spring because of the Kushiro‐Oki Earthquake in 1993. Wow, strange things do happen.

Ajikoen is a single-storied hot spring facility for day trip bath in Osobetsu plain, and has opened a business since 1979. A garden is in front of the building, and is appeal, too. The hot spring facility is famous for enjoying 100% natural moor hot springs with smooth and slipery touch, so onsen evangelists highly evaluate the hot springs, and it is popular with local people, too. An entrance fee to a bath facility is JPY 400. When I watched about the Ajikoen on the internet, the hot springs seem to be effective against atopic dermatitis, and a lot of visitors take out the hot springs in their home.

There are 2 indoor baths at a small tiled public bathroom. The large indoor bath is the size that about 5 peopel can take a bath, and the small indoor bath is the size that about 3 people can take a bath. The large indoor bath does not have a faucet for cold water, and the small indoor bath has a faucet for cold water, so it is allowed to add the water for lowering the water temperature. The hot springs of each baths have been gushing out from a mouth of a lion, and the hot springs have been overflowing from bathtubs, and have been flowing freely. It is very comfortable.

In addition, brown hot spring ingredients that have been precipitated on the bath floor and the lion is a highlight. Probably the hot spring ingredients will not precipitate on the part that the hot springs always flow. A lower jaw of the lion is white, and I suppose that the whole might be white in old days. By the way, the hot springs are used as hot water of showers and faucets at wash places.
