Watching sumo on Youtube has been pretty cool; Sumopool has a well-updated feed, and hpeterswald has some good videos, too, including this English NHK piece on Baruto's ozeki bid. It's not going well so far.
The Nihon Sumo Kyokai has individual pages for the wrestlers linked at the November 2009 Banzuke, including for yokozunas Asashoryu and Hakuho; ozekis Chiyotaikai, Kotooshu, Harumafuji, Kotomitsuki, Kaio; other makuuchis Baruto, Yamatoyama, Takamisakari; and juryo Gagamaru, among the rest.
I remember Chiyotaikai being an ozeki when I lived in Japan a decade ago. There's a great video on YouTube of his namesake Chiyonofuji's 53 consecutive victories in 1988.
