Hello!
Just posting a link to a good site, has a lot of good videos of Sumo bouts (only up to 06, and some don't have all the Honbasho included, but it's still got a lot of good stuff).
Sumo videos (streamed, need Windows Media Player or similar)
Sadly I can't seem to find any videos of this years Hatsu Basho and Haru Basho, which is a shame...
If anyone's got any can you let me know? I know Hakuhō Shō won the Haru tournament and I would love to see his bouts.
I'm also posting a link to one of my favourite bouts of his (not from this site), back in the '06 Nagoya Basho where he beat rival Asashōryū (a great fighter but less of a traditionalist, the first yokozuna in history to be suspended from competition, and a mongolian yokozuna like Hakuhō). For those who don't know the two have had some tension, and in '08 Asashōryū gave Hakuhō a 'shove' after defeating him, and Hakuhō then retaliated by shouldering Asashōryū's in the stomach. Tut tut.
Anyway yeah, this is a good if older video of the two of them, some fantastic technique being used here, with Hakuho looking like he's going to go down a couple times. If you watch carefully though, he's just getting underneath for his final move, the Yoritaoshi.

As I say I haven't seen any of his performances in this year's Basho but I hear he's done fantastically well in the Haru, and did some fantastic throws - I'm especially hoping to find a video of him performing an an uwate-nage on Kotooshu (that's a fantastic overarm throw, looks like this:
Anyway, sorry for nattering on!
