There is a Japanese song that says, ``Bean paste bread has bean paste in them, Jam bread has jam in them, But nightingale bread doesn't have nightingale in them.''
In spring, a Japanese sweet called Ugusu (nightingale) Mochi is sold. The rice cake is covered with green bean powder. That's why Japanese people mistakenly think that nightingales are green.
Japanese sweets inspired by spring in Japan.

You don't see it much outside of spring, so if you're in Japan in spring, be sure to try it.
