### `jp_vehicle_costs_lookup`

- The name "jp_vehicle_costs_lookup" says "lookup": a word for reading.
- Tag private-data: The description's first sentence says "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Japan vehicle statutory costs (車検 法定費用 and annual car taxes), verified against the official pages, by category: weight-tax (自動車重量税 at continuing inspection 2026-05-01 – 2028-04-30: registered passenger cars per 0.5 t for eco, standard, 13-year and 18-year rates, 2-year and 1-year, the full 2-year table to 3 t, kei flat amounts, the 13/18-year counting rules), weight-tax-eco (エコカー減税 period, new-registration bands, first-inspection exemption), cali (自賠責保険 for private passenger and kei cars: 12/24/25/36/37 months for policies starting before 2026-11-01, and 12/24/36 months from 2026-11-01 as keys ending -from-2026-11), inspection-fee (継続検査 fees: 持込, 保安基準適合証 counter and OSS, standard/small/kei, from 2026-04-01, with the previous amounts), auto-tax (自動車税 by displacement for cars registered from / before 2019-10, the 13-year surcharge table and rule, the EV reduction) and kei-tax (軽自動車税 10,800 / 7,200 / 12,900 and the surcharge and EV reduction rules). Each figure carries its value in JPY, unit, the Japanese term, the quoted row from the page, its source URL and effectiveFrom (and effectiveTo where the source states an end); the answer carries verifiedDate, freshness and a citation permalink. No category returns the listing; an unknown category answers covered:false with the nearest keys.
