"Mina Mina Beach in Shimukappu is a unique indoor beach located within Hoshino Resorts Tomamu. My family and I visited it during our trip and were amazed by how it recreates a tropical beach environment in the middle of Hokkaido, even during winter. The pool is spacious—about 30 meters wide and 80 meters long—and kept at a comfortable 30°C. Waves are generated every 30 minutes, adding a fun and realistic beach experience. It’s a family-friendly destination, with a shallow pool for kids, float rentals, and a relaxing atmosphere.

There's also a connected onsen called Kirin-no-Yu, where you can unwind in an outdoor hot spring while looking out at the snowy forest. We found the facilities clean and well-maintained, and there were plenty of rental options for swimwear and floatation gear, though the rental costs can add up. The evening ambiance is especially beautiful, with soft lighting that creates a relaxing mood.

Overall, Mina Mina Beach is a great spot to warm up and relax, especially after skiing or exploring the snowy outdoors. It’s one of the highlights of our visit to Tomamu."

"On May 9, 2025, my wife and I came here to use the public bath. On May 10, 2025, my wife wanted to try the standup peddling, and I would standby in the beach pool. After a few moments of fun, she fell into the water and had problems of maneuvering. I tried to help and soon the lifeguard threw a life ring. With joint effort, my wife was lift out of the pool. It was a good learning experience about our actual capacity."

"Quite a large pool. The layout is efficient. Dressing rooms and showers are placed below the entrance. Towels and lockers are provided. For 1600 Yen you can rent the floats of many forms and sizes. There is a shop at the entrance that sells swimming suits or even rent out swimming suits. You can buy goggles and waterproof handphone covers. Life vest and arm floats are available for kids. Size from a S to LL which can be used for adults There is a shallow pool at the side filled with balls for kids. 4 heated spa pools. The waves come every 30 mins. It's very strong at the start of the pull. There are baths but we couldn't enter due to cleaning. There is a cafe and a gelato stall. Staff are friendly and most are able to converse in english. There is a paddle board you can rent too and play at the deeps pools. The place could be better with slides and better decorations."
