Writing a poem on a long and narrow piece of paper ("tanzaku") and attaching it to a tree or other object can be a way of sending a message. For instance:
once again in love,
once more regret- as fleeting
as cherry blossoms. Date: 1897 (Meiji). Place of creation: Tokyo, Japan. Dimensions: height: 36 cm (14.1 in); width: 24 cm (9.4 in). Medium: pigments on mulberry paper. Collection: Walters Art Museum. Sasaki Toyokichi - Nihon hana zue - Walters 95227
