5 Best Tokyo Train Apps: Where Google Maps Gets You Lost and What to Use
By Atsushi — host at Bon House in Kanamachi, Katsushika ward. I've run it since 2022 and welcomed more than 300 guest groups.
Of all the Tokyo train apps, the one I'd keep if I could only have one is Yahoo! Japan Transit (Yahoo!乗換案内). It goes a level deeper than Google Maps: which platform to leave from, whether the front or the back of the train puts you closest to your transfer, and where a delayed train is right now.
Google Maps still wins at two jobs: walking directions from the station to your door, and long-distance routes that include the shinkansen. So my answer is a two-app setup, Yahoo! Japan Transit plus Google Maps, with the Suica app added if you ride JR on a phone Suica. The catch is that Yahoo! Japan Transit only comes in Japanese. If you can't read it, put Japan Travel by NAVITIME on your phone instead, since it works in English.
Below: how to split the five apps between them, and what trips people up when Kanamachi is their base.
The 5 Best Tokyo Train Apps at a Glance
| App | Cost | Use it for |
|---|---|---|
| Yahoo! Japan Transit | Free | Transfers, platforms, delays |
| Google Maps | Free | Walking directions, shinkansen |
| Suica app | Free | Balance checks, top-ups |
| Japan Travel by NAVITIME | Free (paid plan available) | Route planning in English |
| Japan Official Travel App | Free | Sightseeing plus transport on a first trip |
You don't need all five. Here's how to decide:
- Yahoo! Japan Transit: install it if you read Japanese or travel with someone who does. On Tokyo trains, it's the one app that almost never leaves you lost.
- Google Maps: you probably have it already. Keep it, and let it handle walking and long-distance trips.
- Suica app: install it if you'll ride JR with Suica on your phone. With a physical Suica or PASMO card, you can manage without it.
- NAVITIME and the JNTO app: skip them if you can read Japanese route results. If you can't, NAVITIME is your English stand-in for Yahoo! Japan Transit.
Where Google Maps Gets You Lost on Tokyo Trains
- At some stations it doesn't show which platform to leave from.
- On some stretches it's hard to see whether the rapid or only the local stops at your station. Kanamachi's Joban Line is one of them; more on that below.
- Delay information isn't always updated in real time.
- It won't tell you which part of the train (front, middle or back) is closest to your transfer.
None of these stops you getting on a train. What they cost you is a few minutes of confusion on the platform, and with suitcases or kids in tow, those are the minutes that hurt.
Tokyo Train Apps Compared: What Each Does Best
1. Yahoo! Japan Transit (Yahoo!乗換案内) — free
The standard transit app in Japan, covering JR, private railways, the subway and buses in a single search. When a guest in Kanamachi asks me how to get somewhere, it's the first app I open.
- Sorts results by earliest arrival, fewest transfers or lowest fare
- At major stations, it shows whether the front, middle or back of the train is closest to your transfer or exit
- On JR East, Tokyo Metro, Toei Subway and others, you can see where a delayed train is running
- The weak spot: it's Japanese-only. If you can't read it, this isn't the app to rely on
2. Google Maps — free
Its gaps are listed above, but you still can't travel without it. For walking from the station to your door or to a restaurant, nothing beats it, and it handles long-distance routes, shinkansen included, from Tokyo to Osaka, Kyoto or Hiroshima. If your trip goes beyond Tokyo, it's enough.
What it won't show is whether a train is covered by the Japan Rail Pass. If you're traveling on one, check on the official JR Pass site that your train is covered.
3. Suica app — works with Apple Pay / Google Wallet
This is more an IC card manager than a train app, but it's a practical one: you can check your balance, top up and see your ride history. Checking your balance in the app before you ride beats finding out at the ticket gate.
4. Japan Travel by NAVITIME — English, free version available
A route planner in English, built for foreign visitors. If you read Japanese you won't need it. If you don't, use it in place of Yahoo! Japan Transit.
- Routes that combine trains, buses and the shinkansen
- Linked to information on sightseeing spots
- Saves your recent searches so you can view them again offline
- There's a paid plan, but it doesn't put the whole map offline. Any new search still needs a connection
5. Japan Official Travel App — by JNTO, free
The official app of the Japan National Tourism Organization (JNTO). It's less a transit planner than a mix of sightseeing info and transport, available in English, Chinese and Korean. On a first trip to Japan it's a reassuring one to have, but for transfers alone NAVITIME does the job.
When Tokyo Train Apps Leave You Guessing, Ask an AI
Apps tell you which train to take, not why. That's where an AI assistant such as ChatGPT, Claude or Gemini helps:
- Thinking a route through: "From Kanamachi to Asakusa, is JR or Keisei easier?"
- Snapping a photo of a station sign or a ticket machine screen and asking what it says
- Questions about how the system works: "Should I use Suica or tap my credit card?"
Don't trust an AI on times, fares or delays, though. Its information can be out of date, so always confirm in Yahoo! Japan Transit or Google Maps. AI for the reasoning, apps for the timetable: that split rarely goes wrong.
Using Tokyo Train Apps from Kanamachi: What to Check
Bon House is in Kanamachi, Katsushika ward, which has two stations: Keisei Kanamachi and JR Kanamachi. Ueno is 27 minutes away with one change at Kita-Senju, Asakusa 25 and Tokyo Station 30. Shinjuku and Shibuya take 40–50 minutes, so if your plans center on the west side, it's a long way. If you're covering the east side instead (Asakusa, Skytree, Ueno, Tokyo Station), you'll make far fewer transfers.
Three things will save you confusion when you run Kanamachi routes through a transit app:
- Only Joban Line local trains stop at JR Kanamachi. Rapid trains on the same Joban Line pass straight through. The locals run through onto the Tokyo Metro Chiyoda Line at Ayase, so when your search shows a through service to the Chiyoda Line, that train takes you to Otemachi or Omotesando without changing. Google Maps makes the train type hard to see on this stretch, so Yahoo! Japan Transit is clearer here.
- The Keisei Kanamachi Line is a short branch linking Kanamachi, Shibamata and Keisei Takasago. Narita Airport is about 55–70 minutes away with one change at Keisei Takasago (step by step); Haneda is about 65–70 minutes, changing at the same station (step by step). Shibamata, home of Taishakuten temple, is one stop.
- Don't count on tapping a credit card at either Kanamachi station. Contactless card payments started working across 11 rail operators in the Tokyo area on March 25, 2026, but neither JR East nor Keisei is one of them. Riding from Kanamachi, you need a Suica or PASMO. If yours is a Suica on your phone, check the balance in the Suica app and you won't get stuck at the gate. I cover the basics in our Suica guide for foreign visitors.
Around the station you'll find a shopping street, supermarkets (Maruetsu, Tokyu Store), convenience stores and even a sento (public bath). It's an ordinary residential neighborhood, not a tourist area, so when you get back from central Tokyo in the evening, you can take care of everything between the station and the door.
If you'll spend your days around Asakusa, Ueno and Skytree and want a quiet residential street to come back to at night, check Bon House's availability and rates on our room page.
Narita to Kanamachi, Then Disney: Tokyo Train Apps in Practice
Say a family of four lands at Narita Airport at 15:00, stays in Kanamachi and heads to Disney the next day. Here's how the apps would play out.
Day 1: Narita Airport to Kanamachi. Once you're through immigration and have your bags, open Yahoo! Japan Transit on the airport Wi-Fi and search "Narita Airport → Keisei Kanamachi". Sort by fewest transfers, not fastest. With kids and four suitcases, one change beats shaving off a few minutes every time. You switch to the Kanamachi Line at Keisei Takasago, and the trip takes about 55–70 minutes. At stations where Google Maps shows no platform number, Yahoo! Japan Transit will often tell you which one to head for.
Day 2: Kanamachi to Maihama. Take a Joban Line local from JR Kanamachi to Shin-Matsudo, then change to the Musashino Line for Maihama, about 45 minutes in all. There's one trap here. From Shin-Matsudo, Musashino Line trains bound for Tokyo run through Maihama, but trains bound for Kaihin-Makuhari or terminating at Nishi-Funabashi never get there. Pick a Tokyo-bound train in your transit app and check its time, and you won't be left guessing on the platform. This leg is all JR, so check all four Suica balances in the Suica app before you leave.
Three apps cover the whole trip: Yahoo! Japan Transit, Google Maps and the Suica app. Over these two days there's hardly a moment to open NAVITIME or the JNTO app. For a full comparison of routes from both airports, see our Haneda vs Narita access guide.
Getting Online for Tokyo Train Apps: eSIM, SIM or Pocket Wi-Fi
Every transit app assumes you're online. Without a Japanese line, buy an eSIM before you fly, or pick up a traveler SIM card or a pocket Wi-Fi at the airport. With NAVITIME, search the next day's routes on your accommodation's Wi-Fi the night before and save them, and you can pull them up even where the signal is weak.
Tokyo Train Apps FAQ
Why do transit apps show a different IC fare and ticket fare?
Most JR, subway and private lines around Tokyo charge IC card fares to the exact ¥1 and paper ticket fares rounded to ¥10, so the same trip can differ by a few yen. If you ride with Suica or PASMO, set Yahoo! Japan Transit to show IC fares first, and the fare on screen will match what comes off your card.
Can I use Mobile Suica on a phone bought outside Japan?
On an iPhone 8 or later, yes: you can add one in the Wallet app. On Android it generally only works on Japanese-market phones with Osaifu-Keitai, so with an overseas Android model it's quicker to get a physical Suica or PASMO card.
Kanamachi is one change from both Narita and Maihama, which makes it an easy base to come back to. See Bon House's availability and rates on our room page.
