Water iris

Kakitsubata (water iris) carries literary association in Japan through the Tales of Ise episode at Yatsuhashi and the Noh play of the same name, in which the spirit of an iris recites Ariwara no Narihira's acrostic poem. As a kacho-e subject, water iris typically foregrounds the plant's tall blade-like leaves rising from still water, with the purple-blue petals rendered in the flat color planes characteristic of woodblock printing. Bokashi gradation handles water reflections and the modulation of petal tone from base to tip. Gyokusei's treatment of the motif sits at the intersection of botanical observation and classical poetic allusion that runs through much shin-hanga production, and connects the image to her broader engagement with subjects rooted in the Noh and waka traditions her family had treated for generations. Watanabe Shozaburo's workshop produced kacho-e on this scale alongside her Noh-theater designs.
