Just watched this drama. Yoshiwara (a red-light district in Edo/Tokyo) scenes reminded me of Miotsukushi Ryouri Chou.
This is a "木曜時代劇" series. "木曜" means Thursday. As for "時代劇", please check this page. On an official NHK World English page, it is described as Thursday Samurai drama.
While
watching this drama, a word came up to my head. It is "Cham-ba-ra
(ちゃんばら)". Cham-ba-ra is translated as sword-fighting, but actually, my
idea of cham-ba-ra is not a serious sword-fighting. It's something
silly and a bit funny.
As for the drama, I'll watch the 2nd episode if I have time.
