METHOD / INDEPENDENT BY DESIGN
Every recommendation should show its working.
Japan Ride Math is independently operated. We compare a limited set of verified products, not the entire market. We do not sell tickets or process bookings.
What we check
Each displayed price has an official source and check date. Records outside the freshness window, changed records and ended products are excluded. Other contract conditions have their own check dates. A build date does not mean every fact was rechecked that day.
Rail assumptions
One adult, Ordinary class, one nationwide pass, your start date and entered rides. Normal-season fares are estimates for the named train. Nozomi/Mizuho supplements and uncovered or out-of-window tickets are added. Local rides, discounts, children and regional passes are not automatically included. A difference below ¥2,000 is inconclusive.
Eligibility before price
Check your passport and entry-status requirements with JR. Not every visitor or foreign resident qualifies.
Ads and independence
We may receive a commission from labelled partner links. Ranking uses the calculation only. Official links remain available without commission, including when no pass is cheaper. No firsthand testing or revenue result is claimed.
Before booking
This is a cost estimate, not a timetable, fare quotation or booking service. Check live availability and final prices. The site brand is Japan Ride Math. For tickets, refunds or connection assistance, contact the provider through its official site. We do not offer a booking support service.
