Can I use a Japanese Y name for my non-Japanese baby?

You're free to choose any name, but it's good to be mindful of cultural appropriation. If you appreciate Japanese culture and know the meaning and pronunciation, Yuki can work well cross-culturally.

Can Japanese names with “Y” have nicknames?

No need for nicknames with these as they're already short! But if you've picked a longer name, you can of course create an easy to call nickname for your baby.
