Fuji makes a full range of developing products for film and paper. They also have a variety of papers that are not available outside Japan. Most everything available here is Fuji, Chugai is another local brand. I can really only get Kodak or Ilford chemicals when I'm Tokyo or other big cities.
Off the top of my head, some of the film developers include microfine and super prodol (black and white), and papitol is the paper developer. Drywel is their equivalent to Photoflo, and they have an AgGuard Stabilizing agent which I believe is like Agfa Sistan. And of course stop, fix, and HCA as well. Unfortunately the fix tends to come with a hardener, which I don't like, but the public darkrooms use it. They have colour chemicals as well. Naniwa is another option for colour film and prints.
Since I'm a creature of habit and I like my D-76, Rodinal, and Xtol (I use Ilford products for everything else but the developer), I haven't really tried any of the Fuji chemicals other than Drywel, since Photoflo is impossible to get here. In addition, there is little to no English support for the chemicals or paper. However, the last time I was in a photo store a couple weeks ago the cost of Kodak chemicals had more than doubled, so I may be looking at alternatives in the future. I think there are a few other members currently in Japan here on APUG who have used Fuji chemicals, they might chime in here.
