Utagawa Toyoharu 歌川豊春 (c. 1735-1814) painted a series of ukiyo-e called The Fashionable Six Jewel Rivers 風流六玉川. This one is showing the Jewel River of Bush Clover 萩 in Yamashiro, a historical province located in today’s south of Kyôto. These jewel rivers or crystal rivers were painted by ukiyo-e artists often. You clearly see an influence of Suzuki Harunobu 鈴木 春信 (c. 1725-1770) in the style of this woodblock print.
