Google: Gemini 3 Flash Preview flagged on 日本文化のヒーロー | Japanese Culture Hero: "Factually incorrect. The response claims there are 24 feature films, but the list includes 'Ocean Waves' (1993), which is a made-for-TV movie and not part of the official theatrical feature films. The correct count for theatrical features is 23."

How well can AI systems explain and answer questions about Japanese culture across media, history, and trends? 日本文化のヒーロー (Japanese Culture Hero) aims to reveal commercial LLMs' performance across various domains of Japanese culture.
AI is increasingly used to answer questions about cultures worldwide. But does it truly understand the nuance, history, and emotional depth of Japanese culture — or does it just repeat stereotypes? This benchmark reveals how well commercial LLMs perform when tested by people who actually know Japanese culture.
Questions to think about before you evaluate the response: 1. Would this answer spark curiosity to learn more about the topic? 2. Would this answer help someone trying to understand Japanese culture? 3. Does this answer feel like it includes stereotypes or bias? 4. Is the answer inclusive enough? Does it include different perspectives? 5. Does the response explain the cultural meaning behind its answer? 6. Would I trust this answer if I was studying Japanese culture? If you think the AI response looks good enough, submit "pass" and explain why; otherwise, submit "flag" and provide the reason.
