Wicked Priest 1968

Shinkai, a Buddhist monk with a penchant for drinking and gambling, sets sinners straight with judo throws rather than sermons. After fighting off a gang of street thugs, Shinkai is placed on probation but manages to escape his superiors’ watchful eyes to covertly indulge in life’s pleasures. But when he hears of rogue priests in his order consorting with yakuza, Shinkai must make them see the error of their ways and reach enlightenment, one punch at a time.
