Continuing a dive into Nikkatsu’s vault we have Toshio Masuda’s Red Pier (1958). 
It stars Yujiro Ishihara as “Lefty” Jiro, a ‘50s gangster laying low in Kobe after killing a civilian over a drug smuggling racket. When he falls for the victim’s sister and starts to let slip his involvement, his low-key criminal underworld starts to come unravelled.
