The best site on Sumo that you will find! An example of how things should be done on any site. Miss a bit of control on the graphics, smaller sizes and better programming considering the server speed, but all in all a great experience, congratulations!
The online representative of a very good Budo magazine. In the past the design and structure was better, something happened in the last year that has reduced it’s size and appearanc, but is coming back on its feet little by little.
This site is quite messy when opened in an English language browser, the server is very slow too. But if you are patient you can find some good information in Japanese-English, and quite a bit of graphical material on this Martial Art that derived from the Rakutenkai Shotokai group created by Shigeru Egami.
