Hell Valley and onsen visit.
Then special dinner.
Same cool temperature with a high about 10°C. Sunny day.
A later start today as the tour or excursion as it is called commences at 10 AM. Time for a relaxing breakfast.
We do not like is the tour guides on these excursions. Never stop speaking into a loud microphone. Airpods in noise cancellation mode solves the problem.
It was marked at 80°C
Then to onsen Hotel no pictures allowed of course. Five or more pools, various types, bubbling, sulfur, chlorine, skin exfoliation, hot cold. Large building with nothing with pools in it.
Seafood lunch included in the tour
Guy described this as barbecue seafood. I don’t know any other name, but it was excellent. All of the seafood was fresh and nice to have it right in front of us.

First on the bears: Hokkaido is famous for it’s bear population so you will see stuffed/statues of them everywhere. Most of the island is wild, unlike most the rest of Japan, so there is a good population of them. As a side note, Japan has been having a lot of bear activities near populated areas on Honshu, the main island, including some reports of visits in Tokyo suburbs: https://www.bbc.com/news/articles/cj41vn9q81ko.
The steaming valley reminds me of our trip to Hokkaido where we saw similar steaming valleys, but on the other side of the mountains where you are – a reminder that Hokkaido has lots of volcanic activity resulting in the onsens – unfortunately can’t put images in the comments, but this link will show a similar scene from 1987 https://flic.kr/p/8TqAgR. Were there any folks selling “onsen eggs” – hard boiled eggs cooked in the hot, sulfuric water? [The sign in question basically says to stay on the paths or you run the risk of getting badly burned by the hot water].
The large, flat grills everything is piled in are called TEPPAN in Japanese. Basically, it looks like a yummy seafood tepan yaki…
Good explanations all. Did not know about the bears. Bus tour guide might have said something but I block out with airpods- too loud and too accented. Sharon does the same
