Kankei Bunko Gura Yuuhei Shinpan Kimon Aburaya Some Hisamatsu Tamoto No Shirashibori Yukari No Utazaimon

Inspired by Chikamatsu Hanji's "Osome Hisamatsu's White Striped Sleeves" or "Shinpan Utazaimon" or "Shinju Kimonkaku" (1780)
Emphasis added by Kuroki Kanzo

According to Kuroki Kanzo's theory, the incident that inspired this work occurred in 1708.

The incident was later dramatized and circulated as a kasaimon. It was first staged in 1707 as the kabuki kyogen "Shinju Kimonkaku," but the work that directly influenced "Shinpan Utazaimon" was the puppet joruri "Osome Hisamatsu's White Striped Sleeves," which premiered at the Toyotake-za Theater in 1711. "Shinpan Utazaimon" is a masterpiece of shosagoto (traditional Japanese dance) and has been repeatedly re-created by various schools.

Based on the double suicide of Osone and Hisamatsu, "Shinban Utasaibun" vividly depicts the customs and customs of the An'ei era. The Nozaki Village section in particular was entirely Hanji's creation. While considered a domestic drama, it is a kabuki-style work incorporating elements such as villainous machinations, sword investigations, and the sorrow of repentance.

Osone, the daughter of an oil shop owner, and Hisamatsu, an apprentice with samurai roots, fall in love despite their different social status, but Osone's parents have exchanged betrothal gifts with those of another family. Separated by a cunning scheme, Hisamatsu returns to his hometown of Nozaki Village to marry Omitsu, the biological daughter of his adoptive parents. Osone then appears and announces her pregnancy, declaring that she would rather die than be separated from Hisamatsu. Jealous yet aware of their resolve, Omitsu retires and becomes a nun. Upon Hisamatsu's return to Osaka, news of the restoration of his family's fortunes awaits. However, he is framed for the theft of the dowry through a cunning scheme and locked up in the storehouse.

Okatsu's true intentions and her love for Hisamatsu (The Oil Shop Scene)
This is the core of the story, revealing that Okatsu, Hisamatsu's stepmother (the widow of his employer), who appeared to have bullied him, had in fact deliberately estranged him from his daughter Osome in order to restore his samurai status, raise the dowry, and retrieve the sword.
