This looks good! I'll have an internal Japanese speaker review it. Can you remove commented-out corpora tests?

CI failure seems unrelated, like a transient windows runner bug

EDIT: I restarted CI and it looks good now.

That will be super useful. I removed the commented corpus. Thanks!

Hi @udiu, sorry for the delay. The code received an internal review from Japanese speakers and I need to forward them along here (Normally, I would handle them myself internally, but my confidence that I can do so with Japanese is very low, so I'm going to forward them out externally)
