Overview
Staying connected in Tokyo is straightforward. The easiest option for most travelers is an eSIM, which you can purchase and activate before you leave home. Physical SIM cards and pocket WiFi devices are also available. Free WiFi exists at stations, convenience stores, and cafes, but coverage is inconsistent for daily use.
Having a data connection is especially important for wheelchair users in Tokyo. You will need it for navigation apps, Google Translate (for reading signs and menus), the Check A Toilet accessible toilet finder, and real-time train transfer information.
eSIM (Recommended)
An eSIM is the simplest option if your phone supports it. You buy it online, receive a QR code, scan it, and activate it. No physical card swap needed. Most phones released since 2019 support eSIM, and all US-model iPhones since the iPhone 14 are eSIM-only.
Popular eSIM Providers for Japan
| Provider | Data | Duration | Approximate Price |
|---|---|---|---|
| Ubigi | 3 GB to 50 GB | 15 to 30 days | 9 to 40 USD |
| Airalo | 1 GB to 20 GB | 7 to 30 days | 5 to 27 USD |
| IIJmio | 2 GB to 20 GB | Up to 30 days | Varies |
| Sakura Mobile | Unlimited (with speed cap) | Up to 180 days | Varies by plan |
| Japan Wireless | Various plans | 7 to 90 days | Varies by plan |
Buy and Install Before You Fly
Purchase your eSIM a day or two before departure and install it on your phone. Do not activate it until you land in Japan. This way you will have a data connection the moment you arrive at the airport, which is helpful for navigating the accessible route to the train or bus.
Important: Data Only
Most tourist eSIMs and SIM cards for Japan are data only. You will not get a Japanese phone number for voice calls or SMS. For most travelers this is fine because you can use messaging apps (WhatsApp, LINE, iMessage) and VoIP calls over data. If you need a Japanese phone number for booking certain services, consider Sakura Mobile or similar providers that offer voice plans.
Physical SIM Cards
If your phone does not support eSIM, you can buy a physical SIM card after you arrive.
- Airport purchase: SIM card counters are located in the arrival lobbies of both Narita and Haneda airports. Staff speak English and can help with installation.
- Airport vending machines: Some areas of Narita and Haneda have SIM card vending machines for quick purchase without waiting.
- Electronics stores: BIC Camera, Yodobashi Camera, and Yamada Denki sell tourist SIM cards. Staff at the SIM counter in these stores often speak English. BIC Camera Yurakucho (near Ginza) and Yodobashi Camera Akihabara are large, accessible stores.
- Convenience stores: Some convenience stores sell basic data SIM cards, though selection is limited.
Physical SIM cards are also data only. Prices and data allowances are similar to eSIM options. Bring a SIM card ejector tool or a small pin.
Pocket WiFi Rental
A pocket WiFi device is a small portable router that creates a personal WiFi hotspot using Japan's cellular network. It is a good option for groups traveling together, as multiple devices (phones, tablets, laptops) can connect to a single pocket WiFi device.
Advantages for Wheelchair Users
Pocket WiFi is useful for travelers who use multiple devices simultaneously, such as a phone for navigation and a tablet for translation. It also works as a backup if your phone loses its SIM connection.

Pricing
Pocket WiFi rental typically costs 500 to 1,500 yen per day (approximately 3 to 10 USD) depending on the provider, data allowance, and speed. Most devices support 4G/LTE. Battery life is typically 8 to 12 hours.
Hotel Delivery and Return
Most pocket WiFi rental companies can ship the device to your hotel before you arrive. Confirm with your hotel that they accept packages for incoming guests. At the end of your trip, drop the device in the prepaid return envelope at any post office or hotel front desk. Some companies also have drop-off counters at Narita and Haneda airports.
Free WiFi
Free WiFi in Tokyo has improved but is not reliable enough to depend on as your only connection.
Where to Find Free WiFi
- Train stations: Tokyo Metro and Toei Subway stations offer free WiFi (Metro_Free_Wi-Fi and Toei_Free_Wi-Fi). Registration required. Sessions last 3 hours with unlimited reconnections.
- Convenience stores: 7-Eleven, Lawson, and FamilyMart offer free WiFi inside their stores. Registration required.
- Starbucks - Free WiFi after registration. Available at all Tokyo locations.
- Hotels - Most hotels in Tokyo offer free WiFi. Confirm when booking.
- Tourist information centers - Free WiFi available at JNTO tourist information centers and at ward-level tourism offices.
Japan Connected-free WiFi (Discontinued App Note)
The Japan Connected-free WiFi app, which used to aggregate free WiFi hotspots, was discontinued. Instead, use the Japan Wi-Fi auto-connect app by NTT Broadband Platform, which automatically connects to participating free WiFi hotspots across Japan. Download it before your trip.
Do Not Rely on Free WiFi Alone
Free WiFi in Tokyo is useful as a supplement, but connection quality is inconsistent. You may lose signal between hotspots, and some locations require re-registration after each session. For wheelchair users who depend on navigation and accessibility apps throughout the day, an eSIM or pocket WiFi is strongly recommended as your primary connection.
