I was riding around on the JR trains at lot. It so cool how they dress, mostly formal, where even the students look so cool in their suits, others being dressed to the 9's. There is not really a business casual. And the trains are so busy. This is the platform at midnight. Though it was in Shinjiku, a busier area. Though I was hoping to experience being pushed in the train by the station attendant but it was not that busy. Too bad.
