Eikichi, having trained at an established tofu maker in Kyo, to open his own shop, comes to a traditional town of Fukagawa Hamaguri-cho in Edo to open his own shop, where he meets Ofumi, a true-born Fukagawa girl full of life. With the help of Ofumi's father, Eikichi finds accommodation at the same tenement as Ofumi. Eikichi finally opens "Kyo-ya", his long-planned Tofu shop of his own. Eikichi and Ofumi get married before long and build a home together. The business thrives, but their eldest son, who becomes tired of Tofu making, gets involved with gambling. The shop is taken over by another tofu maker as payment for debts, and the family is on the brink of disintegration. To make matters worse, Eikichi suddenly dies in an accident. Remembering that Tofu making was Eikichi's life, Ofumi and the children decide to protect Kyo-ya.
