The first time I fell asleep on the train I was surrounded by mountains! There are no mountains on the train line near where I live so I knew I fell asleep. The good thing is I can hop off at a stop, cross over, and catch the train back at no extra charge because they don’t take your ticket until you leave the train station. I’ve always wondered what would happens if a person falls asleep on a Shinkansen (bullet train) and Sibylle Ito answered that over at her blog. Another interesting post at her blog is  Japanese manners: Info from an expert where she interviews an experienced trainer for Japanese culture/manner.
