I make it so that my PS4 can change between JP and ENG input language when I use controller to select the letter. However, whenever I type from keyboard, it always come out as English only. I want to type Romanji from my keyboard or Kana, how to do it?

Is there a way to change input language using your keyboard on PS4?

In my PC, I set it so that it change when I click Alt + ~. but in PS4, I can not set that.
