Yamegoku - I will Quit Yakuza (2015)

-Both are Tsutsumi Yukihiko works. Expect a lot of slapsticks, 60's-90's pop culture reference, amazing score, and unique cinematography.
-Yamegoku is basically Keizoku/SPEC, but without the element of weirdness.
-Both drama feature Kitamura Kazuki as a cop dressed and act like a Yakuza.
