This monument to haiku poet Matsuo Basho is engraved with the words, "Buy a sake measure, my wisdom changes as I watch the moon." In September 1694 (Genroku 7), Basho traveled from his hometown of Iga Ueno, passing through Nara and over the Ankoku Pass, to Osaka to mediate between two disciples who were fighting a factional dispute in Osaka. On the 13th, he visited the Takaramonoichi ritual at Sumiyoshi Taisha Shrine and bought a sake measure that was being sold on the approach to the shrine. Basho was feeling unwell at the time, so that night he returned to his lodgings instead of attending a haiku gathering to watch the moon, to which he had been invited. At the haiku gathering the following day, he composed the poem "Buy a sake measure..." and wittyly apologized for his rudeness the previous day, saying, "I ended up buying a 1-go sake measure too. Then my mood changed and I felt it would be better to go back to the lodgings and get some sleep rather than watch the moon." Afterwards, Basho fell ill with a fever and diarrhea, and was taken to bed in a detached room at the home of Hanaya Niemon in Osaka, where he passed away on the evening of October 12th at the age of 51. This poem about the Treasure Market was erected at the east entrance of Sumiyoshi Park in 1864 by the Osaka haiku society Naniwa Gekkasha on the 170th anniversary of Basho's death.
