Sources

This directory's school records are compiled and cross-checked from the public sources listed below — names, addresses, and statuses are re-derived and merged, not republished verbatim. This site is independently run; it is not an official government source, and processing can introduce errors that are not present in the original registries.

For how the data is collected, matched, and kept up to date, see the Methodology page.

  • MEXT Survey, e-Stat, and JASSO Enrollment Statistics

    Government source — MEXT / e-Stat (Portal Site of Official Statistics of Japan) / JASSO

    As of: No single retrieval date recorded for this source (see note).

    Attribution: Source: e-Stat (Portal Site of Official Statistics of Japan) website (https://www.e-stat.go.jp/stat-search/files?tstat=000001221781)

    Multiple annual survey editions (used for enrollment-statistics and legal-reference context, not per-school records), so there is no single retrieval date.

    Attribution: Source: Tokyo Metropolitan Government website (https://www.seikatubunka.metro.tokyo.lg.jp/)

    47 separate prefectural government sites (the URL above is the Tokyo example); used for early signals of school approvals, closures, and renames.

    Government source — National Tax Agency (NTA)

    As of: June 13, 2026

    Attribution: Source: National Tax Agency (NTA) website (https://www.houjin-bangou.nta.go.jp/)

    Not a school directory — a national corporate-identity resolver. Used only to look up the 13-digit corporate number for a school already found in another source, as a stable anchor for matching that school's records across sources.

  • Enrichment & Quality-Signal Registries (MEXT teacher-training portals, MHLW course/license registries, Nisshinkyo third-party evaluation)

    Government and non-government sources — MEXT / Ministry of Health, Labour and Welfare (MHLW) / Nisshinkyo

    As of: June 13, 2026

    Attribution: Source: Ministry of Health, Labour and Welfare (MHLW) website (https://www.kyufu.mhlw.go.jp/kensaku/)

    Trust and quality signals only (e.g. tuition-benefit course designation, registered teacher-training status) — not used to determine whether a school exists or is open.

  • Japan Pension Service — Covered-Workplace Search (Employees' Pension / Health Insurance)

    Government source — Japan Pension Service

    As of: July 3, 2026

    Attribution: Source: Japan Pension Service website (https://www.nenkin.go.jp/service/kounen/jigyosho/jigyoshokensaku.html)

    A rolling lookup tool, not a downloadable list: the date above is when this site last ran its lookups. Queried only by the exact corporate number of an operator already identified from another source, to confirm it is an active employer. School corporations are covered by a separate private-school mutual-aid scheme and do not appear in this search, so a missing match is never treated as a sign of closure.

  • SIKI Japanese Language School Database (commercial directory, ~2019)

    Independent / association source — SIKI (a private company, not a government body)

    As of: June 21, 2026

    Attribution: Source: SIKI Japanese Language School Database (commercial directory, ~2019) (https://www.aikgroup-siki.com/j-school/)

    Unverified secondary source whose content dates from around 2019 (the date above is when this site retrieved it). Used only to fill contact details (address, phone, fax, email, nearest station) that no registry or school website supplied, and never to overwrite a value from a more authoritative source; these details may be out of date.
