It’s right here: photolinks.jp.
If you have some time on your hands, and want to plumb the depths of what Japanese photography has to offer, I can’t think of a better site right now than this one. It’s kind of like a Yahoo! (circa 1996) for Japanese photography; like it says in the URL, there’s just a ton of photo links here. Clicking around the top left part of the menu will take you through the different letters of the Japanese alphabet, and from there you’re off and running.
I haven’t even dug in to this material too deeply, so please let me know in the comments if you find any good stuff.
Photolinks is also on Twitter, it’s probably not such a bad idea to click randomly on the things they’re posting.
I did as you said, and I got a white area where I guessed the links should be.
This was using IceWeasel, which is almost the same as Firefox. I don’t know exactly why IceWeasel didn’t like it, but yes, a look in the source of the page shows a level of ignorance of HTML that I associate with commercial Japanese websites circa 1996; it’s a wonder that any browser manages to display it.
Then I tried it with Safari. Ah, now it worked.
Well, I saw long lists of links. The huge majority were of photographers I’d never heard of, which almost certainly says more about my ignorance than anything else. I thought of looking for several photographers I did know; most weren’t there. I then thought that perhaps I should look for the kind of photographers about whom there was some degree of “buzz”, and therefore tried Watanabe Hiroshi and Nagoshi Keisuke. Watanabe was there; the link took me to his site — as of course Google would have done. (Indeed Wikipedia would have too.) Despite having exhibitions all over the place and perhaps four books in print, Nagoshi wasn’t there. By contrast, Google has heard of him.
I wish photolinks.jp well, but I don’t see myself returning.
