Hi there, just got back from Japan (which was great, by the way).
Thanks to you all for the information, The helpful receptionist at the hotel came with me to the 7-11 and got me the tickets I needed for a game.
I saw Jef Utd get beaten 2-0 by Yokohama Marinos (which was cool as Yokohama play in similar kits to Portsmouth, my team in the UK). The atmosphere was amazing. I will put a link on here soon if anyone wants to see some pictures and video footage.
Thanks again MH
