Aired Nov. 9, 2012 on TBS.
This recap contains spoilers for the drama and the manga, including the Tsunayoshi story arc (vol. 4-6 and the film Ôoku: Eien). Episode 4 recap here; manga analysis here; Ôoku category (film, manga, and drama) here.
Before I start the recap today, I did see the Ôoku: Eien movie, and damn, is it good. Sakai is much, much better suited to playing Emonnosuke, and Kanno Miho was such a great Tsunayoshi. I need to collect my thoughts (and maybe see it again), but the sets are gorgeous, the music is great, and it’s a great “sequel” to the first film.
