If you travel connecting Shirakami mountains and Hakkoda mountains or Lake Towada, going through Jougakura bridge is highly recommended especially in autumn season. The color around the bridge changes into red.
You can walk on the bridge safely after parking at the edge of it. But strong winds on the bridge take away heat from the body.
Look down like a bird at the middle of the bridge ! Deep valley 122m below the bridge is trying to swallow you. The river is so acidic that no fish can live in it.
There is Sukayu Onsen(Hot Spring), the bath of which is made of Hiba wood and can accommodate 1,000 people at a time, but it is also strongly acidic and it makes you tingle when you take a bath, so be careful of people with sensitive skin. It is famous for mixed bathing, but there is a place to take it individually in the back.
