RYOMADEN (2010)

Both are epic Samurai jidaigeki dramas set during Meiji restoration. Both are very similar...................................................

Its similar because they are both taiga's just on different sides and the time might be a little different...

Both movies are based from true events. Both are about patriotism and perseverance. :)

In both Rurouni Kenshin and Ryomaden Sato Takeru plays the role of an assasin from Bakumatsu period. Watsuki Nobuhiro (autor of Rurouni Kenshin manga) mentioned that Jin-e was inspired by Okada Izo (Sato Takeru's character in Ryomaden).
There is more of Ruroni Kenshin's cast in this drama: Aoi Yu, Kagawa Teruyuki and Aoki Munetaka. Film director Otomo Keishi was one of Ryomaden's directors and also Sato Naoki wrote music for both shows.
