Tokyo eSIM

Navigating Tokyo with your eSIM

Tokyo runs on mobile data. The city is enormous and the train system is genuinely confusing the first time, so a live connection takes most of the friction out of getting around.

The train system: your lifeline in Tokyo

Tokyo's rail network is the backbone of the city and it's not a single system. JR, Tokyo Metro, Toei, the private lines and the Shinkansen each run their own thing, which is part of why it feels chaotic. Google Maps absorbs all of it: live departures, platform numbers, transfer walks and the realistic time between connections.

Having your eSIM active means you can check routes on the go, adjust plans when you miss a connection, and navigate the larger stations like Shinjuku (the world's busiest) and Tokyo Station without getting lost. The walk between platforms at Shinjuku alone can take 15 minutes.

If you're using a Japan Rail Pass, Google Maps shows you which trains are JR-covered so you can maximise your pass. Suica and Pasmo IC cards work on most lines and can be loaded on your phone via Apple Wallet.

Shibuya, Shinjuku, Harajuku and the central wards

Central Tokyo has reliable coverage throughout. You'll lean on your phone to track down which floor a restaurant is on (a lot of them are 7B somewhere), translate menus with Google Translate's camera mode, and find your way through Golden Gai's stacked alleys or Shimokitazawa's vintage streets.

You'll use Google Translate constantly in Tokyo. While tourist-facing restaurants often have English menus, many of the best local spots don't. The camera translation feature reads Japanese menus, signs and vending machine options in real time. Download the Japanese language pack before your trip so it works offline as backup.

Uber works in Tokyo but taxis are more common and reliable. The taxi apps GO and S.RIDE are the local equivalents and work well with a data connection. Having a live translation app helps when communicating with taxi drivers.

Day trips: Kamakura, Nikko, Hakone and Mount Fuji

Tokyo works well as a base for day trips, and your eSIM stays connected as you head out of the city.

Kamakura (1 hour from Tokyo) has full coverage. You'll use data to navigate between the temples, find the Great Buddha and check the Enoden line timetable along the coast.

Hakone has good coverage in the town and around Lake Ashi. The Hakone Loop (trains, cable cars, ropeways and boats) is well-served by Google Maps. On clear days you'll want data for the Mount Fuji viewpoint photos.

Nikko has coverage in the town and temple complex. The drive or train ride up has reliable signal.

Mount Fuji's climbing season (July-August) has coverage at the main stations and the summit during peak season. The Fuji Five Lakes area has reliable coverage year-round.

Akihabara, Odaiba and outer districts

Akihabara's electronics district, Odaiba's waterfront, Ueno's museums and Asakusa's Senso-ji temple area all have excellent coverage. You'll lean on translation apps and Google Maps to move through the multi-level shopping complexes.

TeamLab exhibitions (Borderless and Planets) require online ticket booking and digital tickets. Having your eSIM active means you can handle this on the go.

Before you fly

A few things worth doing before you fly:

• Save the Japanese language pack in Google Translate. Camera translation handles menus, signs and vending machines offline once it's loaded.
• Add Suica or Pasmo to Apple Wallet. You'll tap your way through trains, buses and most konbinis without touching cash.
• Pre-download Tokyo's offline Google Maps. Coverage is excellent above ground, but tunnels and dense buildings still drop you out.
• Install GO or S.RIDE. Both beat Uber for hailing taxis in Tokyo, especially after the last train.
• Have a quick look at the train map. Knowing the difference between JR, Metro and Toei makes your Rail Pass go further.

Tokyo eSIM data guide

Tokyo eats data faster than most cities. Train navigation runs constantly, translation runs constantly, and digital tickets for places like teamLab need a live connection to load. Day trips push the daily total up further once you're uploading photos on the way back in.

• 1 to 3GB covers a short stopover of 1 to 2 days.
• 5 to 10GB suits a 3 to 7 day Tokyo trip with regular navigation and photo sharing.
• 15 to 20GB covers a 7 to 14 day trip including day trips. For heavy users, the Japan Unlimited plan takes data off the table entirely.
