[Yakumo Onsen] Day Trip Onsen and Sense of Openness Can Be Enjoyed at Oboko-so

Yakumo Onsen

Yakumo Onsen (八雲温泉) is a hot spring place in Yakumo town located in northwestern direction of Hakodate city. A signboard of Oboko-so (おぼこ荘) is a mark along Kumoishi National Route (雲石国道 * Nationa Route 277), and visitors turn and go straight for around 1 km, and Only Oboko-so (おぼこ荘) is built at around 200 m above sea level at the foot of Mt. Obokodake (雄鉾岳), and is one of secret onsen in Yakumo. The distance is around 20 km away from the center of the Yakumo, and restraunts, cafes, souvenir shops and convenience stores are not built around here. This place was well-known for hot spring gushing out at Yurappu Mine (遊楽部鉱山) in the Meiji period, and Mr. Yonetaro Takami (高見米太郎) built an onsen hut, and it was called "Takami Onsen (高見温泉)" at the time. After that, it was closed down, and Municipal Yakumo Onsen was founded in 1995. Then it was privatized, and up to now. By the way, around here has the legend of hidden treasure that the remnants of Tokugawa's defeated army hide treasure hid the treasure in Hakodate War.

The Yakumo is an unusual town with 2 seas, the Pacific Ocean and the sea of Japan. Famous tourist attractions in the Yakumo are Funkawan Panorama Park (噴火湾パノラマパーク) and Yakumo Ranch (八雲町育成牧場). Speaking of tasty restaurants in the Yakumo, Harvester Yakumo (ハーベスター八雲), Iseya Shokudo (伊勢屋食堂) and Elfin Motoyama Ranch Milk (エルフィン元山牧場牛乳) are popular in particular. I ate sushi and buckwheat noodles at Kameya (亀や) and Marumi Shokkudo (まるみ食堂). Those were so tasty.

Funkawan Panorama Park

Hills Station "Yakumo Panorama Museum" is a roadside station with an ocean view on a small hill in Yakumo town located in the northwestern direction of Hakodate city and is next to Harvester Yakumo (ハーベスター八雲) that is known for a tasty chicken.

Kameya (亀や) is a long-established sushi restaurant in Yakumo town located in the northwestern direction of Hakodate city, and was founded in 1968. This sushi restraunt is famous for getting the Bib Gourmand in MICHELIN GUIDE Hokkaido 2012 Special Edition. There is a building near Yakumo station, but Kameya has no parking lot. Therefore I parked my car in the parking lot of Yakumo Station. Read More

Marumi Shokudo

Marumi Shokudo (まるみ食堂) is a long-established restaurant in Yakumo town, and was founded in 1958. A building is next to Yakumo station and they run an accommodation, too. I visited Yakumo, so I planned to eat Yakumo buckwheat noodles. However, in the first place I misunderstood about Yakumo buckwheat noodles. I thought that it was a kind of buckwheat noodles. Marumi Shokudo uses buckwheat flour produced in Horokanai. By the way, the Yakumo buckwheat noodles is a name of the restaurant. Read More

Entrance of Bathhouse

There are 1 open-air bath and 1 indoor bath at a public bathhouse. A type of the hot springs of the indoor bath is different from the open-air bath. The bathhouse with windows is slightly dark, and is not large, but a sense of stagnation can not be felt. However, I think that bathers are overwhelmed by the large rocks. It is amazing! Rocks for total 250 tons are placed at the bathroom and the open-air bath.

Indoor Bath

The indoor bath surrounded by rocks is the size that about 8 people can take a bath, and uses natural free flowing (2) hot springs with adding water. The shape of the rocks deposited by hot spring ingredients is cool. The hot springs gush out from cleft in the rocks, and the hot springs flow to a downstream outlet. The hot spring ingredients petrify on stagnant hot springs, and float. The hot spring ingredients are rich.

The open-air bath surrounded by rocks is the size that about 30 people can take a bath, and uses natural free flowing (1) hot springs with adding water. The hot springs are an ample supply of water, and always flow to Namari river (鉛川). The open-air bath for women is smaller that the open-air bath for men. By the way, horseflies may prevent you from relaxing in a summer.

As for the open-air bath, it has a great sense of openness! Nothing disturbing eyes. The Namari River flows in front of one's eyes, and the bathers can hear the murmuring of the river, and can take a bath while seeing nature. It is very comfortable. Starry sky seem to be beautiful in the evening. Fresh green can be enjoyed in the summer, fall foliage can be enjoyed in an autumn, and snow can be enjoyed in a winter while bathing, too.
