„This is a movie that was made in the late ’60s, early ’70s period of Japan when Japan influenced by the Hippie culture was experimenting with their own brand of Avant Garde culture that was sometimes called „Angura“. This is shortened Japanese pronunciation for „Underground“. As the word suggests, these were experimental non-mainstream production that explored much about free sex, and anti establishment view of the world. Rengoku Eroica was made during the period of such social movement. The director of this movie, Yoshishige Yoshida (Sometimes pronounced Kijyu Yoshida) always had Avant Garde taste to his movies.
