I am looking for a relatively easy solution for a Japanese spellchecker (not a Japanese dictionary for the Dictionary app) in High Sierra. I would prefer a link to a downloadable spelling dictionary (Japanese websites are okay).
If there are no ready to use Japanese spelling dictionaries, I would be glad if you could point me to a good step-by-step tutorial for making one.
P.S. I already acquainted myself with everything the official Apple website has to offer on the topic. I checked OpenOffice and LibreOffice for Japanese spelling dictionaries and could not find anything that I could make work. I also tried to look for a solution on Japanese and English websites but so far I did not have any luck.
And of course, I did not forget to make sure that my computer is plugged in, turned on, logged into my account, and connected to the internet. It is :).
