Original research and citable data

If what you need is numbers you can cite in a class or a paper, rather than practice links for students:

• Japanese Learning Answer Dataset — August 2026 — raw accuracy from 56,613 anonymous answers by 1,053 anonymous learner identifiers, broken down by skill axis, JLPT level and 39 knowledge points. It covers 2–13 August 2026 (12 days), not a full year. Wilson 95% confidence intervals, full methodology and limitations, JSON and CSV downloads, and APA/MLA/BibTeX citation formats. The data itself is released under CC BY 4.0 — cite the source and you may reuse it, including commercially. ⚠️ The licence covers the data only: our charts, the report text and the rest of this site are not covered. Full terms are on the data report page and in our terms of use.
• How Taiwan Learns Japanese 2026 — a reading of Japan Foundation, official JLPT and JNTO public data alongside our own search behaviour.

Both are collected under Research & Data.
