Odairajuku
An abandoned post town from the mid-18th century that could have been lost to time. But a group of volunteers came to the rescue. They keep up the village and rent out the residences as lodgings. It's a great way to experience the old lifestyle, and help preserve Odairajuku.
Seina-no-Mori Campground
A campground tucked away near Achi Village in the Shimoina area. You can pitch a tent or book one of the cottages and bungalows. There's a tent sauna over a stream and locally baked natural yeast bread.
