ザ・レイクスイート 湖の栖 The Lake Suite KO no SUMIKA

The Lake Suite 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.

ホテルに着き、ロビーに向かう途中、自動ドアが開いたら目の前に洞爺湖が広がっていて感動しました! 客室露天風呂の部屋に宿泊させてる頂きましたがとても清潔感があり素敵な部屋でした! ベランダのソファーは、

When I arrived at the hotel and headed to the lobby, when the automatic door opened, Lake Toya was spreading in front of me and I was moved! Guest room I stayed in an open-air bath room, but it was a nice room with a very clean feeling! Sofa on the balcony

Read more この1年間で三度目の利用ですが、来るたびに良くなっています。特に食事が素晴らしい。量・質ともに道内トップクラス。朝食が本館のバイキングというのがネックでしたが、朝食膳も選べるようになったのが本当に嬉しい。大浴場のインフィニティ露天風呂も最高だし、客室の露天風呂も快適です。現状、洞爺湖で二人旅行ならここ一択でしょう。花火が上がれば完璧だったのですが、コロナの影響で中止。それだけが心残り。

It's been my third time in the past year, and it's getting better each time. Especially the food is excellent. Top quality in quantity and quality in Hokkaido. The main problem was that the main building was a buffet for breakfast, but I'm really happy to be able to choose a breakfast set. The infinity open-air bath in the large public bath is the best, and the open-air bath in the guest rooms is also comfortable. Currently, if you are a two-person trip on Lake Toya, this is the choice. It would have been perfect if the fireworks went up, but it was canceled due to the effects of corona. Only that is regrettable.
