天然豊浦温泉しおさい — Hotel in Toyoura

During my stay in May 2025, I was impressed by the exceptional service and cleanliness. The bath was spacious, well designed, and offered an ocean view, with water of excellent mineral quality.

Our room provided a beautiful sea view, and we enjoyed sleeping with the windows open, therefore I cannot comment on the air conditioning. The soothing sound of the waves was a delightful feature.

The hotel’s location is convenient, just a 15-minute drive from Toya Observatory Point. The on-site restaurant offers a diverse menu at reasonable prices (it’s one of those ticket vending machines kind).

For further reassurance of quality/value; we also saw many locals visiting as well.

I recommend taking a moment to admire the owner’s unique stamp and seashell collection, which features shell-motif stamps displayed alongside the actual shells.

PS. The room design is simple, so check out the pictures. But don’t let that...

The onsen has a sauna and cold pool, 2 or 3 hot pools, 1 bubble pool, and an outdoor pool. It's really kid friendly, with the ticket for a child only being 200 yen! Adults are 600 yen, but there is a discount once a month. I truly recommend you go to this onsen if you are in Toyoura. You...

wonderful baths for the price (600 yen) but do not, i repeat do NOT slide your buttcheeks on the floor of the baths. they are like fibreglass. it's been two days and my cheeks look like they have radiation burns. they are weeping and my underpants are sticking to them in the night.

in summary: baths are excellent but in the name of all that is good, sit still when you...
