It's a groove. The geisha, who bent over and played the koto, looked like a keyboardist. And the zatoh(blinded monk), who swivels his head around and plays the shamisen with great gusto, is probably a guitarist and vocalist. The image above is Toyokuni Utagawa's "Koto Shamisen Tsure-biki (Playing the Koto Shamisen together)" (19th century). I think I saw the soul of the Japanese people here.
Girl’s ceremonial kimono. 1925-1935, Japan. The Kimono Gallery. A small chirimen (crepe) silk kimono created for a girl for either the “ohichiya” naming day ceremony on the 7th night after birth, or alternately, for the miyamairi Shinto shrine initiation ceremony held about one month after birth. 34” from sleeve-end to sleeve-end x 36” height. The Art Deco art stenciled onto this child’s kimono is extremely rare and unusual – the girls parents or grandparents were obviously open to new ideas, as ceremonial garments such as this one typically exhibited traditional motifs. Japanese artists influenced the arrival of Art Deco in the West, however, the artistry on this kimono was at least partly impacted by art developments in Europe and the U.S.
