The 1960’s period of film production in Japan felt a need to explore any avenues from the norm freeing themselves from the oppressive occupying military forces also any shackles of conformity from past idolized auteurs. Anything goes seemed to rule the day. The camera became mobile going anywhere to get a shot and everything looks great even if the narrative has no logical plot or makes sense. These films share a refreshing spirit of abandonment. Their commercial appeal is limited but rewarding for those with adventurous proclivities. You’ll know immediately if you’re a fan or not.
Personally I list left of center and find excitement if the odd and unusual. The Kiikkatsu Noir and Oshima’s Outlaw Sixties from the Eclipse series will share similar appeal.
