It doesn't matter what season it is, or whether I'm at a station or even somewhere outside, I can just get drowsy. During such brief naps, I often think to myself: "Ah, if only I had a futon..." Drowsiness happens no matter where you are. But I always want to sleep properly in a futon.
So then, I tried bringing my futon with me the next time I went out. When you try sleeping in a futon everywhere, you rediscover how wonderful they can be. If you don't consider the fact that carrying a futon around is a lot of trouble, I felt that having a futon right there all the time was wonderful. (Onohoushimaru)
