I’m currently running Libre Office ver.5.1.6.2 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 5.4.3.2. 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?
