Kitani (1895-1947) was a great nihonga painter (i.e. one who uses mineral pigments) and teacher who worked tirelessly to teach, nurture, and promote women artists in Japan.
This is a six-panel folding screen, painted on silk. A woman stands looking through a window at a boy inside, who appears to me as if he's not paying attention to her. This was painted just after the death of Kitani's younger brother, expressing her grief and how she misses him. The title comes from a song for the Buddhist Urabon festival, which is sung to welcome ancestral spirits visiting from the afterlife.
