A more puzzling aspect of it is, if you show up at a rural station near Akita, they'll sell you a multiple connection ticket to a rural station near Nagoya in seconds, using some hyperoptimized mainframe-terminal-style green-on-black text UI. A system that only requires you to know where you want to go does exist, maybe the problem is that every rail company has built their own version of such a system and there is an agreement to not compete online.
