History's strongest disciple kenichi manga is decent. A lot better than the anime.

Vagabond manga = the best in the world.

Kekkaishi isn't very samurai, but I think it's decent so maybe check that out?

Samurai Champloo anime
Death Frenzy anime then manga

u wont find a better martial arts/samurai anime than that.

The name reminds me of Sword of the Immortal, which I thought was very nice. Well, the manga anyways. I didn't enjoy the anime very much.

The Breaker (Manga/Manwha)
Gintama (Anime/Manga) <--- Shit's hilarious and awesome and about samurai
