JDM market trends

Most numbers on this page are direct aggregates over the JDMBUYSELL marketplace — all active listings from dealers and private sellers, plus the last-30-day inquiry leaderboard. The one exception is the pulse chart's buyer-interest line, which is an external industry search-demand index (detailed below) and isnot a JDMBUYSELL marketplace count. Marketplace figures refresh daily; the search-demand index refreshes monthly.

• The pulse chart's new-listings (supply) series is temporarily withheld from this view. The underlying listings.created_at and feed_listed_at values are inconsistent for legacy records carried over from the prior platform, so the series would misrepresent true marketplace supply across the 12-month window. The buyer-interest series is independent of this and continues to render.
• The pulse chart's buyer-interest line is a monthly Google search-demand index for a fixed basket of representative JDM-import search terms (US market), sourced from a third-party keyword-data provider. It is an industry-wide measure of buyer interest — independent of JDMBUYSELL's own inventory or inquiry volume — so it is not a count of JDMBUYSELL page views, inquiries, or sales. Search-volume data is reported with a roughly two-month lag, so the most recent point plotted is the latest month with settled data (not the current calendar month).
• The chart's y-axis is indexed: 100 = the highest single-month value in the 12-month window; every point is shown as a percent of that peak. The raw basket search volume is intentionally not exposed on this page.
• The "What JDM buyers are watching" leaderboard ranks chassis by buyer-intent score: the leader is set to 100 and others scale linearly relative to it. Like the chart's y-axis, this obscures the absolute inquiry volume per chassis. The trend chip still compares the underlying recent vs prior 30-day inquiry counts.
• The pulse chart's headline trend compares the average of the most recent three months against the average of the prior baseline months in the window, expressed as a percentage change in buyer interest.
• Top-10 chassis ranks active listings by count after grouping by make and model. Listings missing either a make or model are excluded.
• Median and average prices reflect asking prices, not transacted sale prices. Actual transaction prices may differ materially. Prices stored in USD and displayed in your preferred currency using FX rates refreshed daily at 05:00 UTC (source: ExchangeRate-API); structured data reports USD aggregates only for citation stability.
• 25-year-rule eligibility is based on the seller's stated production year; actual import eligibility for any individual vehicle depends on the build date stamped on the door-jamb compliance plate (49 CFR 571.7). Consult a licensed US customs broker before transacting.
• The "biggest mover" callout picks the chassis with the highest 30d-vs-prior-30d trend from the inquiry leaderboard, filtered to recent_count >= 3 so a 1→2 row doesn't outrank a 20→70 row.
• A "cars sold" series is intentionally absent from this version. The underlyinglistings.sold_at column carries a recent backfill artifact (historical listings being status-flipped in batches) that would over-report transaction flow if surfaced here. The signal will return once the artifact is distinguishable from organic sales.
• Per-chassis price-change history (e.g. 30-day price change) is accumulating in a price-observation log; the surface that consumes it will appear once enough history has accumulated.
• Export-side Japan auction-hammer pricing is not integrated in this version. Public Japan auction-house data was evaluated and judged non-viable for free ingest.
• This page makes no claims about other platforms. Inventory figures for marketplaces not operated by JDMBUYSELL are not independently verified here.
