Hi, kugiigi.
Thank you for your post.

Yes. I tried to input "Ctrl Space" before.
But, I forget how it didn't work correctly in my situation.
I have already switches my OS. It's fit for me.
I quit to try to resolve this problem.

Thank you.

Hi, AppLee.
Thank you for your post.

I tried to all Japanese layout and I figure out "Japanese (Kana)" can input Japanese partially.

Common Japanese use "Romaji" input method and use 3 types of Japanese ""Hiragana", "Katakana" and "Kanji".
This "Japanese (Kana)" is not "Romaji" input method and can input only "Katakana".

Keyboard layout "Japanese" is correct array of input without "Zenkaku/Hankaku" key.
"Zenkaku/Hankaku" key switches Japanese with"Romaji" and "English."
I want to do so.

Can I switch Japanese and English with hardware keyboard?

Hi, there!

I want to use Japanese language on hardware keyboard connected to pixel 3a. Now my device can use Japanese language on screan keyboard with flick and can use Japanese keyboard layout which input English. My device can't input Japanese language with hardware keyboard. I tryied to install mozc, but it can't available on UT.

So, I want to try to develop IME. But, I am beginner to develop IME on UT. How can I develop like this? I want any documentations and references about this.
