Editorial policy

How we research,
check and update.

We publish our sourcing, comparison, conflict-of-interest and correction standards so that travellers can judge the information for themselves.

Established and last updated: October 21, 2026

Four principles

Useful evidence,
without false certainty.

Our goal is to give you enough context to make a real decision on the day, not to overstate facts for a search ranking.

01

Name the sources

We prioritise first-party information from operators, public authorities and tourism organisations, and list the main sources used by each guide.

02

Show checked dates

Prices, hours, roads and transport can change. We show when information was checked and tell readers to prefer current signs and official notices.

03

Compare like with like

Rates are separated by date, vehicle, insurance, winter equipment and membership conditions. We do not rank figures that use different conditions as if they were equal.

04

Accept corrections

We accept updates from businesses, visitors and local residents, then review the evidence before changing a page.

Sources & verification

Before information is published

  1. Check official sites, public records and information published by each business
  2. Record addresses, hours, conditions, dates and prices separately
  3. Show the source and checked date where relevant
  4. Recheck the evidence when a correction is submitted

If signs at the location differ from web information, use the current sign or the operator's latest guidance.

Operator and conflicts of interest

This site is operated by Onozawa Shoten Co., Ltd., which operates Onozawa Shoten Iiyama Service Station and Nico Nico Rent a Car Iiyama Station. Our services are clearly labelled as operated by this site.

Other businesses are included as useful local options. Active affiliate links are labelled, and commission alone does not decide the order of listings.

Corrections

Tell us when something changes.

The correction form is currently in Japanese. You may also call the operator if a price, opening hour or service detail needs review.
