ザ・レイクスイート 湖の栖 The LakeSuite Ko no Sumika

The LakeSuite Ko no Sumika / Hokkaido Toya 38


"The LakeSuite" is one of the highest-class hotels, located on the serene and beautifully shining lake. You can enjoy the beautiful lake view in the lounge.

We have 4 types, 80 rooms in total under the concept that a modern and relaxing atmosphere harmonized with the seasonal nature of Lake Toya.

In the main guest room with open-air hot spring bath on the terrace, you can enjoy fresh hot spring water since we swap hot water every time new guests come. 

From the terrace, you will have a relaxing time feeling a fresh breeze with the lake view. During the Lake Toya long-term fireworks display, the terrace will be the perfect private seat.

部屋の露天風呂も大浴場の露天風呂もとても気持ちよかったです。 景色の良さは抜群だと思います。 また、バイキングもとても美味しく、満足できました。 また機会があったら行きたいです。 ありがとうございました。

Both the open-air bath in the room and the open-air bath in the large public bath were very comfortable. I think the scenic beauty is outstanding. Also, the buffet was very delicious and I was satisfied. I want to go again if I have a chance. Thank you very much.

Room is good if we stay in two people, but is small for four people. The open-air bath in the room is too cold, and it is impossible without a windshield such as a glass door. The washroom in the open-air bath on the roof is too cold. The pool was also pleased by the children. I think that the buffet for breakfast and dinner is higher than other facilities. Sweets are recommended. We recommend going in the warm season.

I always stay at the “Sun Palace” in the main building, but next to it is the new building “Lake of Lake” and I stayed at it. The room was made in a convenient way just for a newly built hotel, and you could enter the hot spring in the guest room while overlooking Lake Toya in the front, or because it was winter, the outside terrace was not used, but on the inner terrace of the room I was able to spend an elegant time while drinking slowly. This time, we decided to make a buffet plan at the main palace Sun Palace, but after all it will be together with those who are staying at the Sun Palace of a large inn, so it seems that congestion and hustle and bustle are inevitable. As seats are assigned to places that are available, you may be guided to an extremely narrow table. If you are staying to relax, you should have a Japanese meal plan at the foot of the lake. As breakfast has choices only for buffet in main building, we think that it will be good if there are more choices to be able to take breakfast slowly in "Lake of Lake" in the future. Anyway, staying in a brand-new room with a hot spring, welcome drink service, towels are provided in the public bath, and other amenities are well worth the cost I think.
