Train times

Well I am currently on a very busy afternoon train from Yanagawa to Kurume and I confident that I can make the following statement - when on the train between Omuta and Kurume, Japanese commuters will not sit next to you if all the other seats are taken. If they have a choice of other seats they will NEVER sit next to you. In fact the only time a Japanese sits next to you is if they are one of those crazies that wants to try out their English before they have to go back to their hospital...
