How it works

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) use optional FCEV only for future new CSV periods; その他 remains OTHERS. Historical unknown FCEV stays blank with FCV+その他 inside OTHERS, including on force refresh: no historical reclassification. XLSX and confirmed PDF cells supply the split; missing detail is not zero. MarketTop retains its existing inclusive Other class.

The same workbook lists every maker's row, so the fetcher also builds the top-brands tables below (trailing twelve months plus each single month) from it. Each file only holds four months, so the months are kept in market/japan_months.json and the twelve-month view fills up as new files arrive.

Who sells the cars

Whole · last 10 months (2026-01 → 2026-10) · 2,204,125 new registrations in total. Units are registrations; JADA publishes makers, not models, and lumps every imported brand into one row ("IMPORTS (ALL BRANDS)"); TOYOTA includes Lexus. Kei cars are not in these tables either. Powertrain as recorded by the source's own fuel field.

The source does not reach back a full twelve months yet, so the headline view sums the months that exist; it grows to a trailing twelve months as new months arrive.

Render

Each new or changed month re-renders the country. Shares are read from the CSV as column ÷ TOTAL and grouped into three curves. A generalized Weibull S-curve is fitted to the BEV and the ICE share, and the charts, the fitted parameters, the twelve-month totals and the uncertainty bands are rewritten.

Which curve does a CSV column count towards?

Vehicle scope	登録車 (registered passenger cars) only. Kei cars (軽自動車) are NOT included.

Variants

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.

Whole	Registered passenger cars (登録車) — kei cars are excluded.	2012-01 – 2026-10 178 rows	`data/Japan.csv`

History we hold

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 2012-01–2026-10 (178 rows). Some rows additionally carry a time_interval of quarterly; the cadence shown is the spacing the periods actually have.

Which fuel columns this source fills

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.

	BEV	PHEV	HEV	PETROL	DIESEL	OTHERS
Whole	reported	reported	reported	reported	reported	reported

reported column exists but is zero in every row not reported by this source. Hover a cell for the row count.

Caveats

Kei cars (軽自動車) are excluded — the file's own footer says so (「軽自動車は含みません」). Kei cars are roughly a third of the Japanese light-vehicle market, so this is NOT the whole Japanese car market and its BEV share is not comparable with a kei-inclusive figure.
No kei series is charted, and Whole cannot simply be widened to include kei: kei four-wheelers are reported by a separate body (全国軽自動車協会連合会, Zenkeijikyo), whose monthly figures split only by body type (乗用/貨物), model and prefecture — not by powertrain. With no primary source for a monthly kei BEV/PHEV/HEV split, a kei series could only be approximated by tagging individual models (BEV plus an ICE residual, with no HEV) — below the standard of every other series here. Kei passenger cars are EU M1, the same class as Whole, so this is a coverage gap in Whole rather than a missing vehicle class; adding it properly would need a source publishing the monthly kei powertrain split.
