Job description

Overview Japanese exposes AI quickly: it mishandles keigo, mixing polite, humble, and honorific speech in ways that would embarrass a real speaker, and it fumbles counters and particles. It can build grammatical sentences that still land at the wrong level of politeness, and a native reader is who feels the mismatch.

• Score and rank model output in Japanese, catching misused honorifics, wrong counters, and stiff particles.
• Write the better version when the model misses, natural enough to read as native.
