What Travellers Say
Reviews Summary
Tsumagoi Resort Sai no Sato offers a wide array of activities, with its onsen and seasonal water park being major highlights. While some guests note that certain facilities show signs of age, the beautiful grounds and the quality of the hot spring experience are frequently praised. It's a place with potential for a fun day out or a relaxing stay, especially for families.
"This is a great place to spend the day, with many leisure facilities such as go-karting, mini golf, camping, hot springs, soccer fields, swimming pools, and even horseback riding. If you want to spend a few days, just book the hotel and make a schedule of the activities you want to do and enjoy. But for those who just want to spend a day or a few hours, it's definitely worth checking out. The pool area opens in mid-July. There are pools of various sizes for various ages. This is very good because there is a dedicated pool for those who like to jump on the trampoline and a pool for little ones under two years old. Lifeguards are scattered throughout the pool area, which provides safety with children. There is a good area with a variety of food and also tents and chairs for rent so you can relax while not in the pool. Ample parking is available."

"A "has been" hotel that still posts lovely photos of days gone by online. Most of the services posted are closed or off-limits. The condition of the property is a nod to better days of the past, but it is currently a run-down facility. The lovely music hall, practice studios and the nice buffet were the exceptions."
