A seaside resort with stunning ocean views, rejuvenate in the grand bath for beauty and wellness.

Located on the tranquil seaside of Toyohashi, all rooms offer a stunning view of Mikawa Bay. This Resort Hotel features leisure facilities and an Asian resort-style large bathhouse designed for beauty and health. Enjoy the "Garden Carbonated Bath" that promotes blood circulation or the "Radium Bath" made with special ceramic tiles. The water used is "Nano Water," providing a smooth, lotion-like texture for your skin. During summer only, enjoy one of the largest outdoor pools in Higashi-Mikawa (additional fee applies), complete with water slides and wave pools for a full day of fun!

  • Because it was the Obon holiday and we wanted to avoid traffic, we chose this Hotel simply because it’s accessible from Toyohashi Station. The pool looked great in the photos, and it met our expectations.But the Hotel exceeded our expectations (in a good way).Even though we booked the lowest-grade Room, it had a large balcony! The bathroom has a washing area, and you can take off your shoes before stepping into the Room. Is it really okay to receive service like this?We thought the buffet at a pool Hotel would be fine as long as the kids were happy, but there wasn’t anything that tasted bad! Most dishes were above a certain standard, and besides all-you-can-eat crab, there were many seafood-based options.The shuttle bus runs mainly around check-in and check-out times, but there’s also a public bus stop just a short walk away, so getting around is easy.The bath facilities had just been renovated and were spotless.It fills up quickly during summer vacation, so we’d like to make a Reservation early next year.

  • The staff were courteous and kind.The Room was comfortable, and the kids were very happy.Above all, the bath was amazing. Our whole family agreed—it was so relaxing we could have stayed in it forever!!The kids even said, “We want to stay one more night!!” It was that comfortable, and we’re glad we chose to stay here.Thank you for taking such great care of us. We’d love to come again.
