Flying back from the best option.

I don't if this plan is fisable in the amount of time or if I overtake myself.
I wan't to take in as much as possible and see quite a lot of stuff in a comperiable short amount of time in my eys.

To plan further where to stay I need to know if I need to shorten my todo's or if I need more days for it or if I missed something important and special.

So far I want to stay more likely in Ryokans then anything else
