NipponGo: Japan Transit Guide

Japan's transit system is the best in the world, and also the most confusing for first-time visitors. NipponGo cuts through the complexity so you can travel confidently from day one.

Honest JR Pass Calculator
The JR Pass costs ¥50,000+ for a 7-day ordinary pass. Is it worth it for your trip? Most Golden Route itineraries don't break even. NipponGo's calculator takes your actual route, runs the real fares, and gives you a clear verdict, with a buy link only when it genuinely saves you money.

Per-leg Suica & JR Pass validity
Every route leg shows you exactly which card works: "Suica OK", "JR Pass covers this", "Not on JR Pass, buy separately". No more guessing at the gate. The moat no other app offers.

Golden Route coverage
Tokyo inner-city lines, Narita & Haneda airport connections, the Shinkansen to Kyoto and Osaka, Kyoto sightseeing by JR, Osaka subway, and the Hiroshima to Miyajima day trip including the JR ferry, all with exact validity badges.
