I’m currently running Libre Office ver.126.96.36.199 on a laptop with Ubuntu as operating system; and this has the facility to enter text in Japanese using SCIM. I also have a laptop and a notebook both running Windows 10, and with LibreOffice 188.8.131.52. I’d like the facility for Japanese text entry, preferably on both (the notebook is a little short of memory). Can someone help me to do this?
Will this help (or give a clue?): Japanese input in LibreOffice.
