Sukawa Onsen  

Updated: Jun 30, 2023

須川温泉


The hot springs at Sukawa well up tremendous amounts of water – 6000L every minute and the unique water properties can be experienced in many different ways.


SUKAWA ONSEN


There are two lodgings at Sukawa Onsen; one being the Sukawa Kogen Onsen Hotel (bordering Iwate Prefecture) and the other, Kurikoma Sanso (bordering Akita Prefecture. Even if you aren't staying at the accommodations, you are welcome to use their hot springs. Both hot springs provide breathtaking views and have distinctive water characteristics.

Since the Edo period, Sukawa Onsen has drawn visitors because of its therapeutic benefits. The sick would come in an effort to cure themselves, fishermen would come to rejuvenate their weary bodies after months at sea, and many would stay for months in order to regularly use the hot springs. Skin conditions, blood circulation issues, gastrointestinal issues, and gynecological conditions are all known to be helped by Sukawa Onsen.

Although the most common types of hot springs in Japan are neutral (pH 6 to 7.5) to weak alkaline (pH 7.5 to 8.5), Sukawa Onsen is highly acidic with a pH of 2.2 and contains iron(II), sulfur-sodium and calcium chloride. The hot spring is antibacterial, therefore helps with variety of skin problems including eczema. The chloride in the spring allows the body to sweat but still retain heat. Sulfuric acid stimulates the process that oxygenates the blood. Calcium calms the body. The temperature is on the hotter side, and you may experience a slight tingling of the skin due to the acidity and although it’s a bath, it smells like egg…so don’t expect to come out fresh and rosy.


Vibrant foliage during spring and summer – you may be able to see some wildflowers

As you soak in the hot spring, the prominent rock formation Dainichiiwa, dominates the view. In autumn, the rock is decorated with spectacular red, yellow and green foliage – a beautiful contrast with the vivid blue of the hot spring.


What to bring

– Two towels (one to wash yourself and one to dry yourself)

– Cash for the entrance fee

*make sure to take off any jewelry

Sukawa Kougen Onsen has basic amenities such as a shower, shampoo/hair conditioner and hair dryers.

(General hot spring rules: shower before entering the bath. You may bring a towel into the general showering area to cover yourself and wash yourself, but you must bathe naked – don’t bring the towel into the bath with you. You can either fold and put the towel on your head or leave it on the edge of the bath)

足湯 (FOOT BATH, OR “ASHIYU”)

If you don’t feel like hopping into the hot spring, how about dipping your feet in some hot Sukawa water (~50℃)! As it’s at the foot of Mount Kurikoma, Sukawa Course hiking trail, I like to save this part for when I finish the hike – give your feet a good wash and feel your toxins melt away.





ふかし湯 (STEAM HOT SPRING, OR “FUKASHIYU”)


If you head a little up the mountain trail, you will find a steam bath called ‘oiranburo’. There are three rooms with steam blowing out of a hole.

You’ll need to get yourself a ‘goza’ (like a tatami sheet) at Sukawa Kogen Onsen to spread over the steam hole. Bring a towel to cover yourself (you can wear clothes, just underwear or go nude), it also helps trap the steam. Lay down on the goza and have the steam hole blowing out under your back.

The recommended time is around 20 minutes and make sure to have water at hand.   *This space is utilized by both men and women.



ブナの恵み (BUNANOMEGUMI SPRING WATER)




After your healthy, relaxing time at the hot springs, why not make the most of the water in the area and head down to this beautiful little stop to get pure, crystal clear spring water with a pH of 7. ‘Bunanomegumi’ water is recognized as one of Japan’s 100 selected water spots. Its most fascinating and rarest quality is that there is 0.00 general bacteria (一般細菌, ippan baikin) in the water.


Fill up your water bottles and tanks here. Ours is 20L, we use it as our drinking and cooking water at home.




Lastly, when planning your trip to the Sukawa Kogen Onsen area, be sure to keep in mind that the road up closes during November to late May!
