I've never seen it used IRL as well. People tout a 30% speed increase over romaji: https://persol-tech-s.co.jp/i-engineer/technology/key-kana https://persol-tech-s.co.jp/i-engineer/technology/key-kana > this keyboard claims to be faster than direct input due to not needing to move your fingers around That would perhaps work if you remapped the movement to not be linked to romaji, but direct kana mappings. Then it's not just 26 keys combination for the alphabet alone, but 46+ more arrangement, and more for ° and ". With 10 fingers it feels like hell just for standard text input (to note, you can only use 9 for combination as you need a transformation key, and I guess you also need backspace and arrow keys ?), and you add to that punctuation etc. I'm not sure there can be an actual human being effectively typing faster with this...
