Noto fonts are fantastic for multilingual documents, but beware that the CJK versions weigh multiple megabytes each. Loading them as a webfont will eat up a lot of data, not to mention cause a noticeable delay. This is unavoidable when there are 10,000+ characters to encode. My Korean company website loads a subset of Noto Sans, but uses the system default sans-serif if it is accessed with a mobile device. Fortunately most Koreans don't use Hanja (Kanji/Hanzi) anymore, so visual consistency is not an issue.
