The postinst message for www-client/chromium suggests that the user should emerge media-fonts/takao-fonts. However, there is no stable version of this package. Reproducible: Always
Not sure why they recommend that. These days the fonts team recommends media-fonts/liberation-fonts and media-fonts/noto for coverage of all languages. Even so, I guess it wouldn't hurt to have takao-fonts marked stable.
amd64 stable
x86 stable. Closing.
