I slept so well and I think the relaxing onsen bath helped a lot after the long travel (I also just arrived in Japan the day before that). Surprisingly, the futon bedding was so comfortable and soft but I still want a real bed :D

I really recommend that you try a Kaiseki meal if you're in Japan. Every little bowl has something I don't know but is sooo good :) I found one here in Manila but it's just so unreasonably expensive here.
