These Japanese people would be lucky to only get a fine.
A friend sent me this article a few days ago but I'm just getting the chance to post it. Apparently, there is one more thing to worry about when traveling to Dubai: sleeping on the train. A student who was visiting her parents in Dubai fell asleep on the train was woken by a man holding a ticket for 300 dirhams (about US$80). She was unaware that this was on a list of 31 offenses with fines ranging from 100 dirhams to 2000 dirhams. Also on the list is a 100 dirham fine for eating, drinking or chewing gum (chewing gum?!?) on the train. If this was the rule in Japan, Japan rail would be able to buy several new trains a day with the proceeds.
