This custom is connected only with the image of Daruma, it has nothing to do with dragons.
Now I just found out, it is already in Japan from the `` decaying west ' dull political correctness leaked out:
"In the late 1990s, several human rights groups declared that eyeless Darums and their associated rituals discriminated against the blind. For the sake of political correctness, the media chose not to show images of darums without pupils in order for some of the blind to really find this tradition offensive. moments are also cut out when reviewing the events of the past elections. "
How could such a thing come up
