How can I enable Japanese hyphenation in English version of InDesign CC 2014?
Japanese hyphenation is also called Kinsoku Shori.
Thank you in advance!
You have to install the Japanese version.
You don't need to uninstall your version, but you can additional install your Japanese functionality:
Go to the CC application, in the gear symbol you get the preferences, there you can change the language for your programs. Change it to Japanese. Install now InDesign. It will install additional plugins for that language (it is valid for any other language system there too, but don't install all languages as there are existing some incompatibilities, if all are installed on the same computer). You can switch back to your used language afterward.
From now you will find additional functionality for that language.
Thank you so much, Willi! Your instructions were clear, so I could get kinsoku in my English InDesign :-)
