Comment 13 for bug 1540063

@Kenichi: To be perfectly honest, I don't know how to see that. (I speak neither Chinese nor Japanese.)

It's true that the Chinese Noto Sans fonts are now preferred before Takao:

Are some characters present in both Chinese and Japanese? If so, I imagine that the result of the current config file may be a mix of Noto Sans and Takao supported rendering.

In that case it would possibly be better to replace Takao with the Japanese Noto Sans fonts in that config file, so Japanese contents is consistently rendered using Noto Sans as long as the locale is not Japanese.
