Naniwa bunshô yûgiri tsuka (Yûgiri and the Osaka love letter: 浪花文章夕霧塚) was one of many Yûgiri-mono (plays about Yûgiri: 夕霧物). It premiered in 1751 as a sewamono (lit., "everyday piece" or domestic drama: 世話物) adapted from Chikamatsu Monzaemon's (1653-1725) puppet play Yûgiri Awa no Naruto (Yûgiri and the whirlpools of Awa: 夕霧阿波鳴渡) of 1712, the first of the so-called Awa no Naruto mono (plays about Awa no Naruto: 粟の鳴門物). These dramas were all inspired by the death of Yûgiri (夕霧 1654-1678), a celebrated pleasure-woman of the Ôgiya (扇屋) in Shinmachi, Osaka. Fujiya Izaemon (ふじや[藤屋]伊左衛門) was her wealthy young lover. Chikamatsu first dramatized their tale in his Yûgiri nagori no shôgatsu (Farewell to Yûgiri at the New Year: 夕霧名残の正月) in 1678, a month after her actual death.
Fujiya Izaemon stands before a split noren (lit., "woven blind" or curtain: 暖簾). The right half is inscribed こんたん御まくら所 (Kontan omakura dokoro) and the left 大西芝居仕掛大道具場 (Onishi shibai shikake odogujyo), referring to an area hidden behind the stage at the Onishi Theater.).
