Here's how to unlock the Inn scene with kimono.
3 fragments broken
Have the kimono made by the tailor, go to inn, check in (night), switch into kimono, go to open air bath, soak in bath, wear kimono, take a break in the lounge, go back to sleep. Do this 3 times.
This is the next part, you need to have 5 fragments broken.
Go to inn, check in, switch into kimono, go to open air bath, soak in bath, ***don't wear kimono***, leave the changing room naked, take a break in the lounge, go back to your room naked, ***go to sleep naked*** (you have to do this on the first time you go to the lounge naked, or somehow the game breaks and won't give you this next scene***), after you wake up the inn clerk will ask for your room key, go to the changing room and you'll find that your room key is stolen, now you check in one last time, change into kimono, and just go to sleep. The old man from the lounge will go into your room for a scene, and after that the scene will be unlocked.
