Your tengu is a raven, and not a crow?
Reponse:
That’s a good question. After doing more research, I figured out that the birds I see all over Tokyo are crows (Jungle crows to be exact) but I’ve also found that ravens do exist in Japan, just in the colder northern areas like Hokkaido. Shichi was originally inspired by images and information concerning ravens (for example, he has a tuft on his beak that ravens have, not crows) so I will continue to draw influence from ravens, despite the fact that they aren’t as common as crows here in Japan.
