Zatoichi is sworn to protect the life of a young girl and without any real allies finds himself in the middle of a bloody turf war.

眼の見えぬ市（勝新太郎）が、仕込み杖の剣で悪を斬る。「子母澤寛が伝聞で記した小編が、勝新太郎の怪演により時代劇屈指の人気ヒーローとなった。座頭市は天保の頃の盲目の侠客。市という名前以外、本名は不明とされている。通常は揉み治療を渡世として関八州を歩く。博賭もすれば女も好むが、己の信条により非道を行う者には怒りの仕込み杖が襲う。主演の勝新太郎も自ら監督や脚本を手がけるほどの入れ込みようで、仕込み杖を使った逆手の居合いに下駄履き姿など、原作にはない勝新ならではのアイデアが随所にちりばめられている。【この項、時代劇専門チャンネル広報資料より引用】」松平健は、本作のうち第23話「心中あいや節」での庄屋の息子役が正式デビュー作とされている。（実際にはそれ以前の出演ドラマが数本存在する）。一部資料では放送終了が1975/04/07と記載されているが誤りと思われる。また一部資料では結束　信二氏の脚本作品と記載されているが実際のクレジットでは確認できなかった。提供・大正製薬、ニッカウヰスキー、黄桜酒造、カシオ計算機、花王石鹸。

Blind masseur Zatoichi is nursed back to health by a young woman after he is shot by a gang member. Zatoichi, who had come to the village to repay a debt, now feels further indebted. He commits himself to use his amazing sword skills to help the young woman's father, whose river-crossing service is under attack by the same gang responsible for Zatoichi's wounds.

Itinerant masseur and master swordsman, the blind Zatoichi, is near the village of his teacher, Hikonoichi, so he decides to visit. He learns of Hikonoichi's recent robbery and murder and the imprisonment of his virginal daughter, Osayo, in a brothel. Through friendship with Denroku, a local dice thrower and devoted father, Ichi uncovers an unholy alliance between the governor and the area strongman: among their scams is falsifying tax records to put farmers in debt, then forcing their daughters into prostitution at the boss's brothel. With help from Denroku's daughter, Otsuru, Ichi comforts Osayo until he can provoke showdowns with the villains and their henchmen.

After accidentally causing the death of an old lady, Zatoichi tries to do right by buying the lady’s daughter’s freedom from a brothel - but this causes more problems than solves them.

Returning to the village where a year before he had killed Hirate, a much-admired opponent, Zatoichi encounters another swordsman and former rival in love.

Wishing to find peace, Zatoichi travels to his old village but only finds trouble when he ends up in a love triangle and finds old scores have followed him home.

The adventures of a blind, gambling masseur and master swordsman. Zatoichi targets a yakuza-controlled village, because war with a neighbouring town's smaller gang is brewing.
