At Nakasatsunai I recommend you to stay under the beautiful nature.
There are 2 nice places to stay;
The first one is Satsunai River Park.
You can pitch a tent by yourself or rent a bungalow.
For reservation please contact Nakasatsunai tourist office.
Another place is “Feriendolf Memorial Park”.
Inside the park there are lots of big tents already equipped.
You can stay and cook by yourselves.
Inside the park there is also good restaurant.
The following is their official web;
Have a nice nature stay at Nakasatsunai!
