Don't see your language?

The Tier 1 list is a starting point, not a ceiling. If your language isn't here:

• Open a Discussion with the language name + how many learners of Japanese are in that community.
• Tier 2 (Phase 3+) will go beyond Tier 1, biased toward under-represented languages.

How prioritization actually works

1. Phase 1 (now): the 3 live languages get every worksheet across all 4 categories.
2. Phase 2 (next): pick top 4–10 from the roadmap based on combined signal: GitHub vote count + a native reviewer commitment.
3. Phase 3+: same, until we hit 1,000.

The single biggest thing that bumps a language up: someone says "I'll review the auto-translated draft." Without a native reviewer, machine translation goes out as low-confidence beta. With one, it ships polished.
