A friend told me last year that the Suzuka Circuit pool was great, so we stayed thinking we’d be tired after spending the day at the pool. The Hotel is conveniently located—it's close from the parking lot to the entrance, and there are shuttle buses inside, so it’s easy to get to the baths, restaurants, and front desk.
The pool itself was excellent, with a variety of areas for everyone from small children to adults, and there are plenty of shops as well.
The staff were also very helpful. We even bought tickets again the next day and went around the attractions. Our child will be three next year, so we’d like to come back again.
