How to configure Japanese keyboard

[myst426]

Hi! I connected a Japanese (USB) keyboard to my mac and I can't configure the keyboard layout. I've changed the input method to kotoeri but still the "@" is still located in number 2. Can anyone help me?

Thank you

Same problem with my iMac.
Just reinstalled my OS and my Japanese JIS keyboard is no longer working properly - mapping all wrong.
Tried keyboard preferences and adding koteri in input sources but not changing the mapping...

is the main language set to Japanese?

Not sure if that makes a difference but it might...
