What's the Japanese font used when I'm typing Japanese using Open Sans?

I have had both Japanese texts and English texts in my app. And both using the font OpenSans.
But it’s only recently that I have realized that OpenSans is an English font and doesn’t contain any Japanese character definition. This means Figma had some Japanese font automatically replace the OpenSans in the system. Is there a way for me to know which font is that Japanese font?

Thank you for the help!

Noto Sans is Figma’s fallback font.

That’s exactly what I want to know, and it’s great learning to know the official calling of"fallback font"!~
