I’m a Tokyo dad. GO is on my phone for rainy days, late dinners and the days my daughter falls asleep halfway home. This guide covers what visitors usually ask: can you sign up with a foreign phone number, which cards work, how the airport flat rate works, and what a family of four or five should know about seats.

Ramen Dad’s note: I’ve called a GO taxi with my daughter more than once. It’s on my phone for rainy days and the times she falls asleep halfway home.

Quick answer: GO taxi app in English

Setting up GO before you fly

Do this at home on Wi-Fi. It takes a few minutes, and you don’t want to be doing it outside the airport with a tired child.

1. Download “GO / Taxi app for Japan” from the App Store or Google Play. The App Store listing shows English as a supported language (App Store).
2. Tap Sign up and allow location access. GO needs location and notification permissions to work.
3. Enter a mobile number that can receive SMS. Non-Japanese numbers are accepted. Enter the 4-digit code. Finish sign-up before your travel day rather than counting on doing it after you land.
4. Enter your name without spaces.
5. Set up GO Pay with a credit card (details below).
6. Allow notifications so you know when the taxi arrives.
7. Optional but useful: register an email address from the Menu. GO says it’s needed to move your account to a new phone.

(GO: How to register)

What if the SMS code doesn’t arrive? Tap Cannot receive a SMS message? and verify your identity instead. You’ll need a valid passport, a verified email address and a phone camera for a passport photo and selfie (GO: identity verification).

Coupons: GO’s 500-yen sign-up coupon is only for users registered with a Japanese phone number, and GO’s English page says coupon distribution has ended for non-Japanese numbers. Plan on full price.

Data: you need mobile data to call a car and track it. If you haven’t sorted your phone plan yet, my Japan eSIM for families guide compares options. You can also compare Japan eSIM plans before you go:

Paying: GO Pay, cards and cash

GO Pay is GO’s in-app payment. With it, you get out at your destination without paying in the car, and the receipt arrives in the app as a PDF (What is GO Pay?).

(GO: payment methods)

Three things to know:

• Many extras are GO Pay only. The airport flat rate, GO PREMIUM, reservations and ride preferences can’t be paid in the car.
• If GO Pay fails (an expired card, a declined charge), the driver may ask you to pay in the car. Carry some yen. If your card keeps getting declined, try your other card in GO Pay, or skip the app and use a regular taxi rank and pay in the car.
• GO Pay can’t be split with another method. It’s the whole fare or nothing.

Tipping isn’t expected in Japan. The app has an optional tip button after the ride, which you can ignore.

Calling a taxi, step by step

1. Place the pickup pin at a safe spot on the road, on the side where a taxi can stop. A pin in the middle of a building can send the driver to the wrong street.
2. Set your destination. Type the hotel or station name in English. You’ll see an estimated fare, and you won’t need to explain the address to the driver.
3. Pick the payment method and any options.
4. Tap Request Taxi. The app shows the car, its arrival time and a confirmation number.
5. When the taxi arrives, give the driver the number and get in. You can message the driver in the app if you can’t find each other.

(GO: basic steps, setting your destination)

Once a car is assigned, GO asks you not to cancel, and its pricing page lists cancellation fees from ¥500 (GO pricing, Japanese). Make sure everyone’s ready to go before you request your ride.

What a ride costs

The app shows the breakdown on the fare details screen before you request (GO pricing; Tokyo meter rates, both Japanese). The ¥500 figure is the official upper limit for standard taxis in that area; a few companies charge slightly less, and fares outside it differ. Kids don’t change the fare: you pay per car. My child fares in Japan guide compares taxis with trains for families.

Booking ahead

The Reservation tab lets you pick a time from 15 minutes to 7 days ahead. GO is clear that it doesn’t guarantee a car at that exact time; traffic and weather can make it late. Reservations add a service charge on top of the fare (GO: Reservation). For a fixed-time departure, like a morning flight with kids, leave a buffer and keep a backup plan, such as the train or the taxi rank at your hotel.

Family seating: how GO counts kids

This is the part most visiting families miss. GO’s help center explains Japan’s rule (How many people can ride in a car?):

• A standard taxi takes up to four adults.
• Under Japan’s Road Traffic Act, children under 12 count as two-thirds of an adult (three children = two adults).

A family of five doesn’t automatically need a bigger taxi. Two adults and three kids under 12 can legally ride in one standard taxi under these rules, but body size, seat belts, car seats, luggage or a stroller can still make it a tight or impractical fit.

The catches:

• The limit is a maximum, not a promise. Drivers can decline if luggage takes the space.
• GO can’t book by passenger count. For a specific number of people, GO suggests phoning a local taxi company. You’ll find them in the app under Menu > Taxi Companies.
• Luggage: GO can’t request cars by bag size, and whether large suitcases fit depends on the taxi company (GO: large baggage).
• Car seats: taxis are exempt from Japan’s child seat requirement, and GO doesn’t offer a car seat option. The exemption is a legal rule, not safety advice. If you’re traveling with a baby or toddler, bring your own compatible seat or book a transfer that confirms a child seat in advance. Don’t assume a GO taxi will have one. See my car seat laws in Japan guide.

Ramen Dad’s note: We’ve ridden in a regular taxi with a family’s worth of suitcases. Drivers can decline if luggage takes the space, so think about bags first.

Bigger taxis in Tokyo

GO also has a 5-seat Van option, but it’s offered in Osaka, Kobe, Fukuoka, Kyoto and Hiroshima, not Tokyo (GO: Van).

Two warnings:

• New accounts can’t order multiple cars right away. GO says the feature opens after your account has existed for a while (GO: multiple cars). A family of six landing on day one may need GO PREMIUM or a phone booking instead.
• GO PREMIUM cars may not look like taxis. There’s often no roof sign. Match the license plate in the app (GO PREMIUM).

GO at the airport

Haneda

GO’s Airport Flat Rate works both ways between Haneda and these areas: Chiyoda, Shinjuku, Shibuya, Bunkyo, Taito, Sumida, Toshima, Nakano, Setagaya, Suginami and several other wards, plus Musashino and Mitaka. Minato, Chuo, Shinagawa, Koto, Meguro and Ota aren’t on the Haneda list (GO: Airport Flat Rate).

How it works:

• Set the airport as pickup or destination and choose “Airport Flat Rate” as the fare type before you tap Request.
• GO Pay only. Expressway tolls are extra.
• The fixed price includes a ¥400 arrangement fee. If GO expects the meter to be cheaper, it shows you the regular fare instead.
• At the airport, you can only board at designated spots, marked ● in the app.

Important for bigger families: GO PREMIUM can’t be used with the Airport Flat Rate (GO PREMIUM). If you take the larger car, expect the meter plus the premium charge, and tolls.

Where to meet your GO taxi at Haneda, per the airport’s own site (Haneda Airport: taxis):

• Terminal 1: departures level (2F), near Exit 7
• Terminal 2: departures level (2F), near Exit 2
• Terminal 3 (international): P5 parking garage, 8F. Allow time to get there with bags

These are separate from the regular taxi ranks. Follow the pickup spot shown in the app. With kids and bags, the regular taxi rank downstairs is often simpler: no app needed, and flat fares apply to many wards (for example Shinjuku ¥9,000, Shibuya ¥8,500, plus tolls). My Narita and Haneda to your hotel guide compares both with trains and buses.

If you’d rather not deal with pickup areas after a long flight, a pre-booked private transfer is another option. Compare vehicle size, luggage space, child-seat availability and the total price before you book:

Compare Haneda airport transfers on Klook ↗Affiliate link. Prices and availability can change.

From the app, GO’s flat rate only works toward Narita. Leaving Narita, GO says you can’t request a flat-rate taxi in the app; ask the driver after you get in. Narita’s own taxi rank has flat fares to Tokyo zones without booking.

FAQ from parents

“Do I need a Japanese SIM to use GO?” You need mobile data, not a Japanese number. Sign-up works with a non-Japanese number, or with passport verification if SMS doesn’t arrive.

“Can GO send a taxi with a car seat?” GO doesn’t list a car seat option. If you need one, bring your own or ask a taxi company directly when booking by phone.

“Will the driver speak English?” Not necessarily. That’s why it helps to set the destination in the app before the car arrives.

“Can I call a taxi for my partner and kids while I wait with the luggage?” GO has a help page on requesting for someone else. The simplest option is to request two cars from one account, once your account can order multiple cars.

“Is GO cheaper than Uber in Tokyo?” Both can send licensed Tokyo taxis, and each adds its own fees. Compare the fare breakdown each app shows for your trip.

“What happens late at night?” GO dispatches at night if cars are nearby, but there may be fewer. Most companies add 20% from 10 p.m. to 5 a.m.

Before you fly: GO taxi app checklist

1. Install GO and sign up at home, with your phone number or passport verification.
2. Add a credit card to GO Pay. Apple Pay works only with JCB or Amex.
3. Save your hotel as a favorite location.
4. Count your group: adults + kids under 12 × 2/3 must be 4 or fewer for one taxi.
5. Five or more? Check the kid count first (2 adults + 3 kids fits one taxi). Then think about bags and car seats before choosing GO PREMIUM, two taxis (not on brand-new accounts) or a phone booking.
6. Keep some yen in case GO Pay fails.
7. At Haneda, decide between the GO pickup area and the regular taxi rank before you land.

Ramen Dad’s note: If you remember one thing: count your group and your bags before you call. Then pick the car.

Rules and fees checked against GO Inc.’s website, help center and App Store page, Haneda Airport and the Kanto District Transport Bureau on October 10, 2026. GO’s fees vary by area and demand, so check the fare details screen in the app before you request.
