Shin-Tamagawa Onsen - Semboku

One of the best two hot springs in the world, great radiation rocks

Good place for relaxation and body refreshing. The breakfast and dinner buffet are very delicious.

Very special onsen. All you can eat dinner and breakfast. Would love to visit again someday.

Very packed. Canteen food not good. Main onsen is big. Several types of pools. Has a small outdoor pool.

it was 2nd time visit, it's just absolutely the best onsen ever I had.. I love its rotenburo in winter snowy day! and staff in front are so warm and kind.

The water is strong acid. Many kinds of baths, including 50% diluted ones and more diluted one.

Chinese guest smoked in the room! hotel did nothing to the complaint The hotel is annonced as ａ non-smoking hotel from 2015, but I have reported Mr. Sun [孫] of room 211 who stayed for 2 days of 14-16 June 2019, ostensibly a Chinese descendent, smoked all day along. I told this to the hotel management but it did nothing, and did NOT fine the culprit Mr. Sun for the amount of JPY300,000 according to its rule set out in the hotel pamplet. VERY disappointed, as we came hear to improve our heath but this hotel allows the DEADLY 2nd hand smoking to further devastate our lives and murder us!!!. ACTION IMMEDIATELY to expel those who smoke in the room like this Chinese guest Mr. Sun! make sure hotel punish guests smoking in hotel room.

HOTSPRING CURES! A visit to Tamagawa Onsen on the Hachimantai Plateau, one of the most famous in Japan,  is a must.  It is fed by a wellspring of 98-degree Celsius hot-spring water, and at a pH level of 1.1 and a discharge volume at 9,000 cubic meters per minute, it is has both the most acidic water and the highest discharge volume in Japan! Next to the Tamagawa Onsen ryokan is a small trail to the spring gushing very hot stream. Visitors may closely observe gas fumaroles with yellow openings attributed to sulfur deposits along a nature trail. Bedrock baths for those seeking hotspring cures especially for cancer are available as the area has a significant amount of radioactive radium. It is also famous for the discovery of hokutolite, a rare mineral containing radium. Guests at Shin Tamagawa are offered a free shuttle service and entrance to Tamagawa Onsen Ryokan. We reserved a seat for the 12:30 pm-14:05 pm shuttle service. A special vehicle with triangular wheels to navigate there icy and snows covered roads was used to get us to Tamagawa Onsen Ryokan. The spa area offers similar types of bath options to those in Shin Tamagawa. Shin Tamagawa's spa area is at least 10% bigger at 50 x 30 feet (~ 20 x 10 metres) with twelve baths.  Types of baths offered include steam baths, cascading baths, bedrock baths, and rotenburo, with different concentration of acidic waters. The 100% acidic hotspring water being the most popular with the Japanese guests. All baths are gender segregated, and friendly to the physically challenged. There are also three family baths with different concentration of acidic waters, each measuring about 20 x 8 feet (~ 3 x 7 metres), which should be reserved with the front desk. Be forewarned that the acidic waters can be biting. Guests are advised to shower before and after a soak. Guests can also partake in activities like table tennis, karaoke, and bingo (¥100). There is also a gymnasium with exercise machines and yoga mats. Reservations for use at the frontdesk. :p Meals are buffet style, and vegetarian friendly. Many guests to the Onsen are here for the curative treatments offered by the hotspring waters, hence meats and sashimi are somewhat limited.
