Introduction
Hello! I’m Ken, editor-in-chief of Tokyo Insider Guide.
In 2026, Japan’s tourism infrastructure is digitizing faster than ever. While many apps used to require a local Japanese phone number for registration, we’ve seen a surge in “God-tier” apps that now work perfectly with international numbers!
In this article, I’ve hand-picked the best apps (excluding payment-only apps like PayPay) to make your transportation, translation, and sightseeing incredibly smooth. This is a lineup that even locals swear by, far beyond what you’ll find in standard guidebooks.
Ken’s TIP: Having the right apps can change your entire travel experience. Make sure to download and complete the registration “before you board your flight to Japan” so you can start moving like a pro the moment you land!
【Ken’s Choice】 5 Essential Apps You Need to Install
I selected these based on their actual usability for foreign tourists using international smartphones.
1. 【The Transit King】 Japan Transit Planner
Google Maps is great, but if you want to master Japan’s complex railway network perfectly, the multi-language version of “Jorudan” is the strongest tool available.
- Why is it useful?: It tells you exactly which car is closest to the exit and which platform number your train departs from with higher precision than other apps.
- Ken’s Point: It features a dedicated “JRP (Japan Rail Pass)” search mode. It filters routes to exclude “Nozomi” trains instantly, making it a must-have for pass holders.
2. 【The Trendsetter】 LUUP (E-Scooters & Bikes)
Those green electric scooters and bikes you see all over the streets? You don’t need a Japanese driver’s license! Anyone with an international passport and a credit card can use them.
- Why is it useful?: It has revolutionized travel to places that are “too far to walk, but too close for a train.”
- Ken’s Point: You must pass an in-app traffic safety test (available in English, Chinese, and Korean). It takes a few minutes, but once done, you can ride freely across Japan!
3. 【The Taxi Standard】 GO
This is the most widely used taxi app in Japan. Since 2024, it has supported registration with international phone numbers (USA, Korea, Thailand, etc.), making it a game-changer for tourists.
- The Benefit: Just pin your location, and a taxi arrives in minutes. You can pay via the app, meaning no need to explain your destination in Japanese or handle cash with the driver.
4. 【Translation Genius】 VoiceTra
Developed by Japan’s national research institute (NICT), this app is a hidden gem. Its accuracy for “spoken Japanese” is significantly higher and more natural than Google Translate.
- Ken’s Point: It excels in complex situations like talking to station staff or at a clinic. It is completely free, has no ads, and is a must-have for any foreign traveler.
5. 【Luggage Savior】 ecbo cloak
The ultimate app for those struggling to find coin lockers. It allows you to reserve storage space in cafes or shops instead.
- Why is it useful?: Coin lockers in major sightseeing areas are almost always full. With this app, you can book a spot in advance so you don’t have to wander around with a heavy suitcase.
