Hack for rendering Chinese/japanese names without a comma between the family and given name using standard CSL (and not Juris-m)
(based on this thread from the Zotero forums: https://forums.zotero.org/discussion/110097/using-the-note-field-for-rendering-mutilingual-text-with-csl#latest )
Add the following to the "contributors" section of the Chicago 17e Author-date format. Something similar should work for other styles. You may need to add something similar to deal with multi-author works. This assumes that your Authors are listed like this in Zotero:
Last/family name: Ōtani
Given/first name: Yūka 大谷由香
