The following review is an extract from the book "Shintaro Katsu´s Zatoichi: Complete guide to all movies", which is now available on Amazon.
"This is the sixth part of a saga of films shot in the 1960s about the adventures of the blind swordsman Zatoichi. Always motivated by deep convictions and a strong sense of honour, on this occasion Ichi must shed light on the robbery committed against humble peasants in order to prove that he had nothing to do with the crime. Two intriguing women, the clever Ogin and the young Chiyo (sister of the warrior who killed Zatoichi the previous year) will try to prevent the blind masseur from fulfilling his laudable purpose.
(...) In "The chest of gold" we have the rare privilege of seeing in the same film the two masters of the chanbara genre: On the one hand Shintaro Katsu as the heroic Zatoichi and on the other his brother Tomisaburo Wakayama (Ogami Itto en Kozure Okami / "Lone Wolf and Cub") as his antagonist the evil ronin Joshiro. Just as in "Zatoichi's Pilgrimage" (also directed by Kazuo Ikehiro) his opponent Tohachi (Isao Yamagata) has as particularity his skill with kyudo (archery), here Joshiro stands out in the use of another weapon or combative technique: the whip."
