Hoshino Resorts KAI Poroto

Onsen facilities, especially the outdoor baths, receive strong praise for relaxation and scenery. Minor downsides include occasional crowding when a cave bath is open to non-guests and a limited free-drinks lounge.

Rooms and public areas are generally very clean, with some guests describing spaces as spotless. A few mentions note dust or hair in a changing area and seasonal mosquito issues.

Guests highlight spacious, comfortable rooms with thoughtful design, quiet interiors, lake views, and, in some cases, private onsen. Some note very soft mattresses, long walks to certain rooms, small or underwhelming in-room baths, or missing bottled water.

Service is consistently friendly, attentive, and professional; staff proactively assist with needs such as taxis and communicate well in English. Isolated concerns include slow flexibility on room reassignment and limited accommodation for Western breakfast preferences.

Scenic lakeside setting near nature. About a 10 minute walk from JR Shiraoi Station; taxis are recommended in snowy conditions, and basic shops and eateries cluster near the station.

Dining is widely praised for high-quality, locally inspired multi-course meals. Some guests found flavors too fancy or underwhelming, noted limited Western breakfast alternatives and only one restaurant with required reservations, or felt paid upgrades and kids options were lacking.
