We are thinking of a side trip from Tokyo to Kusatsu onsen to have an overnight there.
Our whole Japan trip is not long, just about 11days. We've been to Japan multiple times and this time we are only doing Tokyo. But we love onsen and winter snow. We were looking for a small onsen town for a side trip and this seems what we are looking for.
We want to make the whole travel as relaxed as possible. We got Tokyo accommodation sorted and we don't want to fix the date for this side trip, if possible. Ideally we want to see how we go in Tokyo and take off when we feel like it.
Is it possible to find an overnight accommodation when we get there without prior reservation?
I'm talking about a trip in this month - soon. We will leave Australia this Sunday and the side trip will be probably next week, mid week.
Any advice would be much appreciated. Thank you!
