Takaragawa Onsen Osenkaku is a traditional Japanese inn tucked away in a valley by the Takara River in Minakami Tanigawa Onsen in Gunma Prefecture. The ryokan uses traditional Japanese architecture and has a history that spans over 80 years.

Takaragawa Onsen Osenkaku features an open-air bath that measures more than 330 square meters, the biggest in the hot spring area. It has also appeared in various media like magazines, television shows, and posters–one film, in particular, is “Thermae Romae II”.

The ryokan has 42 rooms with traditional Japanese elements–tatami mat flooring, shoji sliding screen doors and windows, and futon bedding. Guests are also provided with yukata robes during their stay. The rooms are also equipped with a television. One night’s stay can range from 25,000 to 35,000 JPY. Guests who are staying are also welcome to choose from various yukata to wear while they are around.

Guests are invited to relax and unwind in the indoor and outdoor public hot spring baths, one of which is situated along the mountain stream, and, as with its other outdoor baths, harmonizes with nature. There are three communal baths in the establishment and one that’s restricted for only women. The water is sourced from four types of hot springs.

Takaragawa Onsen Osenkaku also has a restaurant that serves dishes that feature seasonal ingredients from around the area. Some dishes include mountain vegetables, wild boar, bear, and river fish–tourists are invited to dine on local delicacies, a specialty being bear soup.

Takaragawa Onsen Osenkaku is accessible by taking the train from Tokyo Station to arrive at Jomokogen Station, or via Takasaki Station and transferring to Shim-Maebashi Station, and then to Minakami Station. The establishment is operating normally with safety measures in place and limited acceptance to prevent the spread of infection.

Excellent location, worst Japanese food I’ve ever eaten
First of all I must say, the location/onsen itself is amazing. Quite possibly one of the best in Japan, breathtaking views and also tattoo friendly. The food that was served to us on the other hand was a different story. Dinner was presented to us as a kaiseki meal, but instead of having everything coursed out like a normal kaiseki meal, it was all just strewn out on the table. Most of the food was clearly just frozen food thawed out and presented to us. Sashimi clearly smelled fouled, completely cold grilled fish, and duck meat that was chewy and tough like old boots. We decided to leave before the “Gohan” course of the meal which was the only thing coursed to us at the end of the meal. Our server asked us why we were leaving so soon as to which we told her that the meal was basically inedible. She responded with “I’m sorry” instead of trying to elevate the situation and give us something a bit more satisfactory, almost as if this is a commonality for her. With my 20+ years in the hospitality business I would be the first to tell you that you never apologize for anything because it’s clearly admitting that your food/service is sub pay at best. Later in the evening I spoke to some Thai tourists (I lived in Thailand for 2 years) asking them what they though of the food, and without any sort of hesitation told me they thought it was terrible. My wife, who is Japanese also spoke to some Japanese tourists that also said similar things but were a bit more reserved due to the culture nuances of Japanese people in general. The following day we made a complaint to the manager at the front desk about our experience and basically told us the same thing that our server the previous night told us “I’m sorry” and even went as far as telling us that other people have complained in the past and that “he would inform the kitchen of this matter. No comps for anything, no “we’ll make a better experience for you the next time on us” just “sorry” and basically shrugged his shoulders. Despite the amazing location or not, my wife and I spent lots of money and our valuable time to visit this place expecting an incredible experience. Needless to say it’s highly doubtful we would ever come back unless it’s complimentary on the house. Bring your own food, or go to another onsen

Worst Ryokan & Onsen in Japan
I have visited over 100 onsen ryokans during my years of living and visiting Japan. I came here on a quest to find the best rotenburo in Japan. So, I splurged for the most expensive room/stay of my life. Although I did capture a few nice photos from outside, the overall experience was my worst in 28 years of Japanese travel. The room was dilapidated. It was as if nothing had been maintained since Japan's economic bubble burst in the early 90's. The river view I paid for was only visible if you leaned up against the windows while standing. Hallways were freezing. All staff were generally nice. However, when I returned from bathing in the late afternoon, I asked the front desk for a pitcher of ice water. They said a pitcher would be left in the room during dinner, and refused to get one when asked. In general, the food was the worst I have ever been served in any hotel or ryokan in Japan. Everything seemed canned or just low quality. At $430CAD/night, I expect at least a couple slices of wagyu. The baths were lukewarm at best, and, actually cold in some places. Only lying awkwardly next to the hot water inlet would result in tolerable temperatures. All baths were too shallow. Changing rooms were not heated. Outdoor lounge area fire was out (probably for decades) and there were no other heaters. Distances to walk outside, in sub-zero January temperatures, were extreme. The haori should have been warmer for walking outside. The towels everyone must wear while bathing are stupid, unless they are to allow photography of the scenic setting. But, photography is officially banned in the bath area. And yet, absolutely every other bather I saw, was blatantly taking photos in the bath area. Why is there still a women only bath, apparently with the only heated changing room, if all bathers must now cover up with those mandatory towels. It should be communal as well, or rotate women/men only, in the morning & evening. This huge complex did not have single massage chair or massage service. The dining room, shuttle bus and baths were all filled with 95% foreigners. Most that I spoke to had never been to a ryokan onsen before, so they don't realize how bad this place is compared to others. I think that is why there are not more negative reviews. Difficult to get here. I felt completely ripped off by my stay here. I will never return. The water and walks are so cold, it is not even worth coming for winter day use.

Not that nice.
I should believe some comments in here. 😔 This onsen already turn to be a place for tourists and the room is quite old. Onsen has a good view but crowded with hotel guests. Service and food were just ok. If you want to get japanese onsen experience,better go somewhere else.

Idyllic setting under the snowy winter
Takaragawa Onsen is like an onsen from fairytale during the winter. It is so picturesque when snow falls. The location is perfect being next to the river. Onsen with sounds of river flowing and water from Onsen was truly sublime under gentle falling snow. The onsen water was good, but not the best . The food at the onsen serves Japanese food in Western setting. It is buffet style with a basic kaseki dinner set. The actual time at the hotel is however limited for one night over nighter. This is because hitel bus take guests back to station at 9am, after arriving late at like 4pm . It is best to stay at least two nights to truly experience the onsen.

This Hot Spring Resort was truly amazing and child friendly!
If you like the wilderness, this place is Utopia. The water temperature was about 38°C or 100°F. The open air baths are mixed gender, so do not be surprised if someone of the opposite gender jumps into the pool with you. However, the resort does ask you to cover up your private area, and will supply you with a towel-like gown, free of charge. The only demerit was, these gowns “do not” come in children’s sizes. So, children seven years and younger are left to wear something of their own, or to run around the open air baths naked. Which a lot of children were doing... Dinner and breakfast was a Viking style, all you can eat buffet geared towards foreigners’ taste. Truly nothing out of the ordinary or traditional. Overall, this place was really clean and relaxing. Our nine-year-old twins loved it!
