Okay, I understand.
I certainly wouldn't bring a bed over if I was visiting someone else's house and they had one already prepared for me.
The futon I have is pretty thin, so I guess that explains why it is so uncomfortable to sleep on. If I do use a futon in Japan, I'll make sure it's extra thick!
I guess like Tsuwabuki said, it all depends on how you arrange your living space. But it's gonna be awhile before I visit Japan, I'm just fantasizing right now.
