How JapanTolls verifies toll data

Every figure on JapanTolls is traceable to a named source and a verification date. This page explains how the Japan data is collected, checked, and kept current.

Where the data comes from

Japanese expressway fares are looked up interchange-to-interchange in NEXCO's public route search (mk_route.php), the same engine behind DrivePlaza, and the road master that lists every NEXCO interchange. Each route page names the entry and exit interchanges and the date of the lookup; Shuto and Hanshin urban expressways are billed separately and are not folded into NEXCO figures.

We prefer the operator's own tariff table, fare search tool, or official notice. Community map data (OpenStreetMap) is used only to describe a road's geometry and length, never to price it. When no official figure exists we do not publish a price.

What "last verified" means

The date shown next to a price is the last day we compared it with its source. The whole dataset carries its own version date, currently 2026-08-19, shown on the home page. Prices are not adjusted for inflation, discounts, or time of day unless the source publishes those variants.

Vehicle classes

Operators use different category systems. The calculator maps them to four buckets: motorcycle, car, light truck, and heavy truck. The country guide explains the mapping for Japan, and when a source publishes only one class we show only that class rather than extrapolating the others.

What we never do

Four rules apply to every page:

Invent or interpolate a price where the operator publishes none.
Copy figures from other calculators, forums, or social media.
Show an amount without a source and a date.
Hide that an amount is an estimate rather than an official quote.

Coverage today

JapanTolls publishes 30 toll roads with sourced details, 1321 route estimates, and 8 editorial guides for Japan. Roads and routes without a sourced figure are kept out of search engines until one exists.

Corrections and independence

Report errors through the contact page ([email protected]). We check the report against the official source and update both the figure and its verification date.
