Hello, It is I Super Mel
Welcome to the Microsoft Community.
Hello, thank you for your feedback, as my native language is not Japanese either, but I still did some research and testing for you, you can open the language logo in the bottom right corner of your computer and find the option marked below if it is open you can turn it off and try it, it may work.
Thank you for your time and effort in resolving this issue.
Best regards
