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?
