I started a directory a few months but it wasn't until just recently that I really worked on it and finally completed it enough to advertise it publicly. My directory is JapanDir.com, a directory for websites on Japanese music, movies, anime, shopping, language, general culture, and more. There's only one option to list a link at the moment, normal free links. So if you've got a Japanese-related website, consider submitting it!
Hi ... your site reflects your hard work. I like very much. Wish I had a qualifying web site. Good luck.
Thanks! Yes, it seems harder to run a niche directory because while people do submit links regularly, most of them are completely unrelated to my topic and I have to remove them.
