I have to admit, my heart stopped twice when I saw a group of little kids and then a girl with two cages filled with four cats board our cart...eeek! "Please let me sleep." But in typical Japanese fashion, as soon as the train started moving everyone became silent and the next 12 hours flew by! I missed going underneath the longest underwater tunnel in the world and would only occasionally wake up when I heard the conductor stomp through our cart. Now this is the kind of traveling I could get used to!
