I would like to share what I did in order to have no italics in the user interface and (more important to me) to gain access to the Japanese keyboard while still seeing the menus in English. This is now even more useful, as the Japanese dictionary is searchable (since around FW 3.16.10).
This is just for information for those who like to tinker. I do not have a good idea how to provide tools so that everybody who wishes so can easily do this by herself.
I extracted the English translation file from nickel, named it trans_ja.qm, and copied it to usr/local/Kobo/translations. Then I set the user language to Japanese.
This hack survives FW updates. It has to be reapplied only after FW resets or if the translation strings of the GUI changes significantly with a new FW.
Side effects: The date in Settings/Date Time is displayed in Japanese.
While writing this post, I think I found an easy way to make this available to everybody. I have to test this idea.
