Here is a complete list of the Taiga dramas done by NHK. They have been airing them since 1963. Most of them are 50 episodes long, 45minutes a piece, though the opening and closing are usually a bit longer. They generally air from January to December here in Japan. A condensed version is often aired at the end of the year. As far as I have known only two dramas have been repeated, Ruyuku no Kaze and Takeda Shingen

The ones I asterixed are available in condensed versions from NHK video
http://www.ntkr.co.jp/foa/ . Mind you they are of course in Japanese and they are frightfully expensive. The Takeda Shingen one for example is five cassettes and cost 37,800 yen (I guess about $400). I don't know where one would find them for sale with english subtitles. Tokugawa Ieyasu is available in its complete form 26 cassettes, astronomical price. NHK also does other historical dramas usually during new year along with many other stations here in Japan. Though recently they have become quite scarce. I have managed to copy about 133 different titles of samurai /historical dramas on video. This info came from the Japanese magazine TV Guide (Gaido). They publish a guide book to each series every year.
