"Showa Nihru / Mt. Arizu" is the most anticipated spot around Lake Toya, a hill on the southern shore of the lake, and the top of the mountain with a 360-degree view of Hokkaido, including the sea, lake, and volcano. There are two main observation decks at the top of the mountain, one of which is the Toya Lake Observatory, which overlooks the gentle lakeside view of Toya; The other is the Mt. Suzu Crater Observatory, which faces the Ginnuma Crater, and if you want to explore the mysterious volcano further, we recommend following the crater hiking trail to see the lava valley and the steam-breathing crater up close, and experience the wonderful scenery of nature. Arisan Crater Observatory / If you want to explore this mysterious volcano from the crater observatory, you can see the volcanic terrain up close by following the trail of white smoke and lava valleys, and the surrounding land is completely devoid of vegetation due to gas eruptions. The trail takes an hour and a half to go back and forth, all of which are boardwalks, and there are several steps with cylindrical wood embedded in the narrow front edge, which is very difficult to step on and feel that you will fall if you are not careful, so you only walk the first half of the trail and turn back. This is the second time I came to Mt. Auriju this year, but the first time I came was because the snow was too thick in winter, the cable car was stopped, so this was the first time I officially came up to the top of the mountain, and I saw that the top of the mountain has an endless view, there is a rich and varied view of the sea, lake, and volcano, and looking down from the sky is completely different from the feeling of enjoying it on flat ground, and it is highly recommended that you come to Lake Toya and walk around Mt. Aruzu. Of course, the place to stay at night is to choose the Gin Yu Pavilion! It takes about 1 hour and 41 minutes to drive from the Arisan Ropeway via National Route 230, which is not very far, and you can enjoy the scenery along the way.
