using japanese keyboard in pages
I'm using the Japanese characters keyboard input on my MacBook Pro M1. When I start typing hiragana I get a line below each character I type and then a pop up menu makes suggestions, in some cases changing what I type to kanji. So far, the only way I can type what I want is to switch back to the US keyboard (which is a pain after typing just one word).
How do I stop the lines from appearing so I can type hiragana without stopping?
