Yes, Bic Camera in Hiroshima is where I got the stuff from. They had all kinds of stuff and they had a great film selection. It was strange to see 8x10 sheet film just sitting there in the freezer next to 35mm. Anyway I knew about the place but I don't understand Japanese to order off the website.
I didn't see any Rodinal there, but I wasn't able to spend the amount of time in there that I wanted to on this trip. We just happened to pass it on the way back to the train (I had my family with me) and after forcing my family to walk about 6 miles that day all over Hiroshima my wife was not too receptive for me having a photographic side adventure if you know what I mean. I am going to go back alone this weekend to check out everything else.
