Note10+'s Samsung Keyboard has No Japanese support?

[mas921]

I just got my N975F, CSC:XSG, but i could not find the Japanese language in the Samsung Keyboard languages???

I have it on my note8 (latest XSG update).

I have the same concern.  I have enabled it on my S9+, but also couldn't find it on the Note10+. Suggestions on how to fix this are very much welcome!
