Amagiso is truly one of the most unique and fascinating outdoor onsen experiences I've ever had. The outdoor baths are incredible, especially with the view of the giant Odaru waterfall—it feels like you're completely immersed in nature. It's tattoo-friendly, which is a big plus for those of us who usually have to be cautious about where we can enjoy hot springs in Japan.

There are several different onsen to choose from, each offering its own vibe. You can even take a dip in the river to cool off during the summer, which is such a refreshing experience. And if you're into sauna culture, they have a tent sauna that's perfect for unwinding after a long day.

This place is just amazing, and it's easily one of my top choices for an onsen getaway. The combination of natural beauty, variety of baths, and relaxed atmosphere makes Amagiso a must-visit spot.

Amagisou is actually also a hotel for those who want to spend the night here, however the hotel is currently under construction.
