Japanese bath... It got weird

Staying at a 'ryokan'- traditional Japanese house - for a night in Tokyo. Let's start with my bedroom :

Tatami mats ? I don't even know. I know that I paid extra to sleep on the ground 

And then there's the bath...

Mini showers. I think if you have buddies you all shower and get naked together

Then I had a 'bath'. Aka I sat in the hot tub for a while.

I do like these fancy Japanese robes though !
