Shingu Sayaka (born 1979) is a contemporary ceramic artist based in Osaka, Japan. After having graduated from the Osaka University of Arts in 2003, she joined an apprenticeship program at the Shigaraki Ceramic Cultural Park in Shiga, Japan, where she was deeply moved by the work of contemporary artist, Sugiura Yasuyoshi. Her work is celebrated for its naturalistic forms, particularly for her ceramic sculptures of cut flowers, which are constructed from mixed clay with slip and glaze using intricate hand building and glazing methods that embody great care and restraint in her craft. In her functional works, she references butterfly wings, feathers and natural ephemera.

She takes on a quintessentially Japanese aesthetic tradition which celebrates the ephemeral, and has quoted a celebrated verse by the 9th century female poet Ono no Komachi as a distillation of many of her themes:

花の色はうつりにけりないたづらにわが身世にふるながめせしまに

The flowers have withered / Their color faded away / While I spend my days in idle sorrow / As the rains of my past life fall.
- From the anthology of Waka poems, Hyakunin Isshu (百人一首)

Her work has received significant attention and awards, including selection for the 42nd Asahi Ceramic Art Exhibition and exhibitions at the Art Institute of Chicago, Kyoto Arts and Crafts Biennale (The Museum of Kyoto), The Portland Art Museum, and more.
