The charm of Saiunso, Toshichi Onsen. Let’s stay at a hot spring inn in the sky!

Saiunso, Toshichi Onsen, is the highest hot spring inn in Tohoku, located in Hachimantai City, Iwate Prefecture.

You may find yourself escaping from the hustle and bustle of everyday life as you enjoy the smell of sulfur in the spring water and the unique air of the highlands. Here, we will introduce the charm of Saiun-so, a hot spring resort in Fujishichi.

Saiunso’s location


Saiun-so, a hot spring resort in Toshichi, is located at an altitude of 1,400 meters above sea level in Hachimantai, overlooking Mount Iwate.
Located in the Towada-Hachimantai National Park, Saiun-so is a hot spring resort that is closed during winter and spring due to snow accumulation. It remains open only from April to October every year.

In the early mornings when the weather is good (around 4:30 in summer and 5:30 in autumn), you may be able to see the sunrise and sea of clouds that only Hachimantai can offer. This is a great place to take pictures.

Hachimantai, where the Saiunso hot spring resort is located, is also famous for its trekking trails.
The alpine plants such as Mizubasho and Hina-zakura in June, and Kinugasa-so and Hakusan-shakunage in July will make your eyes water.

From Tokyo, it takes about 110 minutes by Iwate Kenpoku Bus after getting off at Morioka Station on the Tohoku Shinkansen Line, or you can take a bus from Kazuno-Kanawa Station on the JR East Line or Tazawako Station on the Akita Shinkansen Line.

During the summer and fall, you may be able to take the free shuttle bus (Morioka Station to Saiun-so, Toshichi Onsen), which is available only for guests with advance reservations.

If you are driving, the Hachimantai Jukai Line is closed at night (from 5:00 pm to 8:30 am the next morning), so it is recommended to take this into account.

The charm of Saiunso

Saiunso's hot spring

One of the charms of Saiun-so hot spring is the sulfuric spring, which is located at an altitude of 1,400 meters above sea level. The natural spring water is poured directly into the bathtub, so you can fully enjoy the ingredients of the simple sulfur spring.

In addition to the women-only open-air bath, there are also the mixed bathing open-air baths of Ichi-no-yu, Ni-no-yu, San-no-yu, Shi-no-yu, and Touhachi-no-yu. Bathing hours for guests are 24 hours.

Enjoy the scenery that changes with each season: cherry blossoms in spring, fresh greenery in early summer, cool breeze and starry sky in summer, and autumn leaves in autumn.
