I just developed my last Kodak roll of TriX today. I ordered 25 sheets of Hp5 4x5 and 20 rolls of HP5 in 35mm this morning. I have cut all ties with Kodak film. If only I could get ilford developer shipped to Japan I could be done with Kodak chemicals as well.
You can get Ilford chemicals in Japan -- just not in Hiroshima (at least, I couldn't find any the last time I was there). Head south to Fukuoka and pick some up at Yodobashi Camera next to Hakata Station. Yodobashi and Bic Camera also still carry a lot of (Ilford) film, paper, and chemicals in Osaka and Tokyo. Or get Freestyle to ship you some from the U.S. -- not cheap, but it's a viable option.
My favorite thing is to go where I've never been. D. Arbus
