jphripjah-I am interested in your experience buying direct from the Ham Fighters website. I would not mind reserving a seat for a game in early September. You mention they give you a QR code. Can you elaborate a bit? Does that mean you get a code when you buy the ticket on line and then use that to enter the stadium?
I am not really interested in the 7-11 system as you mentioned having to pick up the ticket the next day. Kind of difficult to do when I am not yet in Japan. Normally if I buy tickets once in Japan I just go to a Loppi machine at Lawsons and buy them there. That machine I can work in a jiffy.
