JDM chassis code list
Japanese-market chassis codes with the production start and end of each code, and a source you can open for every date. The list holds 649 codes across 8 makes and 105 models, and was last updated November 13, 2026 (PT). Download it as CSV or JSON, or read it one make at a time below.
The register by make
One page per make, grouped by model. Each row carries the production dates, the US 25-year line and the source for both dates.

Find a chassis code
Filter the whole register by chassis code, an alias or sibling code, make or model. The search loads the register index when you type; with JavaScript off, every make is still listed above and every code is on the make pages.
649 codes across 8 makes. Type a code, model or make to narrow the list.

How to read this list
What each column means, and how far the dates can be trusted.
Dates are Japanese production windows
Start and end are the first and last months of Japanese-market production for that exact chassis code, as the cited source states them. Where a manufacturer has not published production dates, the sale date is used instead and the row's note says so. A month appears only when a source states a month; otherwise the date is the year alone, or "unknown".
Confidence
Confidence describes the sources behind the two dates, not how interesting the car is.
| Confidence | What it means |
|---|---|
| High | Both dates come from a manufacturer source, and no source disputes them. |
| Medium | At least one date comes from a Japanese catalogue or Wikipedia, not the manufacturer. |
| Low | Sources conflict, or the dates rest on thin evidence. The note says what is disputed. |
The US 25-year line
"US 25-year line from" is the month the earliest build of that code turns 25 under the 25-year import rule: the production start plus 25 years. It is a reading aid, not a verdict. Eligibility always comes from the build date of the car in front of you, which can be later than the first build of its code and is often a different month. Check the plate: is it US legal yet? works the dates out from the chassis code and the build month you enter.
Codes, aliases and siblings
The code is the bare chassis code from the plate, such as JZA80. Aliases are the prefixed forms of the same code that Japanese registration uses (E-JZA80, GF-JZA80). Siblings are other codes of the same generation (another engine or body), which share the generation window but can be built for a narrower period.

The CSV is UTF-8 with a byte order mark, so Excel shows the Japanese source titles correctly. Every field is quoted, rows end in CRLF, and aliases and siblings are separated by semicolons. The JSON carries the same rows as objects, with the production dates split into year and month and both sources as URL and title.

Found a mistake?
A wrong date here can cost someone a car, so corrections need a source.
Send the chassis code, the date you think is wrong, and a link to the manufacturer page, catalogue or other source that states the correct date. Contact the desk and the row is corrected with the source cited, or the note says why the sources still disagree.
General information only, not legal, customs or tax advice. Dates are researcher readings of the cited sources and can be wrong; eligibility is decided by the build date of the specific car. Confirm current requirements with CBP, NHTSA, the EPA and your state motor vehicle agency before importing.
