Hi @Yoshiya Takabayashi 

Welcome to the Miro Online Community!

Many users already have requested the multi-language support wishlist in the community!

I hope they will soon work on it & release it!

HI @Yoshiya Takabayashi,

I have some really exciting news to share with you! 

We've been working really hard localizing core features and functionality in additional languages, starting with Japanese. So you can now switch languages in your Profile Settings.

We’re at the beginning of our journey to localize Miro for you, so ​​not everything is translated just yet. Please bear with us as we continue to update additional features this year and beyond.

Learn more in the Help Center (English | 日本語) and let us know what you think in the community announcement post.
