Typing hiragana or other japanese fonts

hi! I have japanese keycaps stickers. I would like to create a layer in chrysalis to be able to type them directly by pressing the key with the right sticker on it. How can I do it? I see that in Chrysalis there is a menu LANGUAGE / INTERNATIONAL but I dont know how it works.

How do you type those symbols on a “normal” keyboard?

(You’ll probably need to change your keyboard layout settings on your computer to switch between Latin characters and Hiragana.)
