Hi @yamatatsu , ありがとうございます for the PR, really appreciate your eye to spot the errors!

I have checked the typos in my IDE and we have a lot more to fix. I have opened an issue #1825 so we can track them all. Would it be ok for you to go through all of them and fix it this PR?

Thank you for your contribution. 🙏
