A haiku monument by the haiku poet Matsuo Basho, inscribed with the words, "Unohana and the dark willows." This poem was composed by Basho when he frequently traveled from his hometown of Iga-Ueno (present-day Iga City) to Osaka and Kyoto. This haiku monument, which is currently erected a little south of Tamagawa Bridge on the Tamagawa no Sato path, is characterized by its unique font, which was carved in 1843. The Tamagawa River in Takatsuki is counted as one of the ``Six Tamagawa Rivers,'' along with Tamagawa Rivers in Yamashiro Province and Omi Province, and is a scenic spot that has been sung in poetry since ancient times. ``Unohana'' (Japanese name: ``Utsugi''/also known as Takatsuki flower), which blooms in the village of Tamagawa in Mishima, Settsu Province, from May to June every year, has been known as an old poem and song pillow since the Heian period, and since the Edo period. It often appears in haiku and senryu poems during this era. It would be nice to take a walk around Tamagawa in early summer when the white flowers of Unohana bloom, thinking of Basho.
