Wakoku and Nippon

I read an article on Wikipedia that back in the days Japan had an alternative name, Wakoku. That roughly means Humble or submissive country. 

Surely that is not the most flattening of names, however such name suggests that Japan possesses the most important of 7 Heavenly virtues, that is humbleness. That is one of the reasons why the world just loves Japan.

In contrast China, who calls itself a Central Country or Middle Country, possesses a deadly sin instead. That of Pride.

I guess we can mock China by calling the Chunibyo country.
