Did you install the Japanese version of ID?
No I didn't Peter.
You might need to do that to access those features. Presuming you are a CC subscriber, open the CC App and use the gear icon to change your language preference to Japanese, then log out and in again and I think the Japanese version will show up for download. Change your language back to English after the download. The interface should remain in English, but the additional features should appear.
Brilliant! Thank you so much.
When I logged in again to the CC App after changing the language to Japanese, it indicated that I could install InDesign (even though ID was installed) but there was no reference to it being a Japanese version. However, once installed all the Japanese features were there. I did have to restart my computer to make it work properly. I have not changed my language back to English, but all the menus are in English, only the panel menu is in Japanese but the panels themselves are in English. And there is still only one copy of ID on my computer.
