We were really surprised how wonderful Semi Onsen ryokan was.
The lodging is located only 10mins from the resort and the free shuttle was ideal. The onsens were clean and there are several to choose from. The in-house massage service was excellent and the staff really know how to relax exhausted muscles. The best part of staying at Semi onsen is the food. A sumptuous set menu with a plethora of courses each night was a taste sensation and adventure.
We can’t recommend Semi onsen or JSA highly enough. Thanks again Hisae

Semi Onsen is great.
Skiing was amazing again this year
Ski patrol was pretty aggressive. We didn’t understand and the trail map is not clear. They have a few tree runs but the rest of the area between lifts is out of bounds. It isn’t roped off and the trail map doesn’t say out of bounds and much of it is just as skiable as the actual tree runs. I think they would be better with a Tomamu system and rope off the areas that they really do consider dangerous and avalanche prone. Let skiers ski the rest.
Best Wishes

Yes all went very well, excellent Onsen and accomodation was good. 
Only problem for a westerner was the breakfast ... still have trouble with full Japanese breakfast. 
It apart from that everything else was good. 
Maybe a couple more western options like some fruit and breakfast cereal might help. 
Some good coffee would help as well !

I don’t want to tell you this, because I would love to keep it a secret,  but Semi Onsen Ryukan was awesome. The location, staff and hospitality was great.  They would go out of their way to help with any, and everything. When it came to food, you are in for a treat, with the best Japanese food around. (my only complaint is, it would be nice to have an English option for breakfast). The rooms were spacious and well presented. Definitely want to go back next year.
Thanks so much for all your help.
Kind regards

Semi Onsen ryokan is an amazing place with lovely staff and a good variety of onsen to sample.
The kaiseki dining for breakfast and dinner was amazing (and a little challenging at times!) and our Japanese style room overlooking the river was clean and reasonably spacious.
We had a car so we didn’t have to rely on the ryokan’s shuttle up and down the hill to Geto (~15 mins each way).
Geto was definitely a powder magnet but due to a big snow pattern coinciding with the New Year holiday it was heaving with local snowboarders making the most of things. Good on them – having a hill like this 30 mins or so up the road from home would be awesome!
Be aware if you are seeking tree runs that the tree courses don’t open until around mid-January – they certainly looked very attractive when we were there first week of January but alas, only the little Rabbit tree course was open and no-one was ducking ropes.

The service, the Food, the helpful friendly staff and the rooms are as good as Hakkoda. The choice of Onsen even better.
There is one issue which my wife didn't appreciate very much and this is the shuttle service to and from the ski slopes. It didn't bother me but she would have liked at least one additional service in between. This might become a big criteria for our next trip.

Semi Onsen was very nice. The staff were welcoming and it was great having a choice of 2 onsens, including outside onsen. The food was also very good. Good wifi and nice Japanese style room. The free shuttle service to Geto Kogen was also appreciated.
I would recommend to westerners to stay during the week as I think Semi Onsen, Kitakami and Geto Kogen are very popular with the Japanese on Fri and Sat nights.

I am back from Japan.  My 3 days at Geto & Semi Onsen were perfect. 
Thanks for your help.

Japan Snow Accommodation hooked me up last minute with 2 days of skiing at Geto and 2 nights accommodations at Semi Onsen Ryokan. Semi Onsen was excellent!  The staff was incredibly friendly and helpful.  They have shuttle service to/from mountain.  Kaiseki dinner and breakfast were one of best I've had while staying at any traditional Ryokan in Japan.  Lastly, the Onsens at Semi are worth the trip alone.  If you are going to Geto Kogen highly recommend staying at Semi Onsen!  Thanks to Hisae at Japan Snow Accommodation and Semi Onsen Ryokan for a great trip.

We enjoyed the Skiing but the Semi Onsen  was fabulous. The staff looked after our every need and they were delightful the best Japanese experience. If they wish to improve on an already great experience adding a dedicated shuttle bus with a bit more flexibility would make just that much better.Would most certainly go back.Thank you for the work you put in to make that happen.
Kind regards

It was our first time staying at a ryokan and we loved  the Japanese experience at Semi Onsen. The rotenburo was my favourite and was simply beautiful. Often, I had it all to myself. The local ladies and other Japanese visitors who visited the onsen were so friendly, that I finally got some much needed Japanese practice.  We stayed in a western twin room that was immaculately clean, quite spacious and comfortable. The staff were very accommodating and helpful. The meals were Japanese style with many, many beautifully prepared, delicious courses.
