New-vehicle registrations for Japan from the dealers' association (JADA).
Japan's registrations come from JADA (Japan Automobile Dealers Association), which publishes a monthly 燃料別メーカー別登録台数（乗用車） file — registrations by fuel type and manufacturer. Each publication is a rolling four-month rollup; we take the newest month. The XLSX is parsed by preference, the PDF is a fallback layout carrying the same data.
Fuel-cell vehicles (ＦＣＶ) and その他 are summed into OTHERS.
Go and check the numbers yourself:

| Acquisition | File — downloaded as a data file (XLSX / Parquet / ODS / zip) |
|---|---|
| Vehicle scope | 登録車 (registered passenger cars) only. Kei cars (軽自動車) are NOT included. |
| HEV (full hybrids) | split into its own column |
Each variant is its own series with its own CSV. Not every variant is charted in the gallery — the CSV is the authoritative record either way.
| Variant | What it counts | Held | Raw data |
|---|---|---|---|
| Whole | Registered passenger cars (登録車) — kei cars are excluded. | 2012-01 – 2026-07 175 rows | data/Japan.csv |
Every bar is the span actually present in our stored CSV — breaks in a bar are real gaps in the series, not rendering. Cadence is shown on the right.
Whole 2012-01–2026-07 (175 rows). Some rows additionally carry a time_interval of quarterly; the cadence shown is the spacing the periods actually have.
A blank column almost never means "no such cars" — it means this source does not split them out, and those vehicles are counted inside another column. Check the caveats for where they land.
