Yes, Verizon works in Japan. Your phone connects automatically to Verizon’s TravelPass at USD$12 per day for talk, text, and data on the SoftBank or KDDI au network. For a one-week Tokyo + Kyoto trip that’s USD$84 just for connectivity. An eSIM for the same trip starts at USD$8. Below is an honest breakdown of when each option is the right pick.
This is written by Travelren, an eSIM brand. We sell Japan plans, so we have a stake. We’re going to give you the real numbers and tell you the scenarios where TravelPass is genuinely the better call — there are real cases.
The quick answer
- Verizon TravelPass in Japan: USD$12 per day, only on days you use the network. SoftBank or KDDI au is the carrier you’ll connect to.
- Travelren eSIM, 3GB / 30 days for Japan: approximately USD$8.20 (around AUD$12.50 / GBP$6.60)
- Crossover point: for any trip 1 day or longer the eSIM is cheaper. For a 1-week trip the eSIM saves USD$76.
How Verizon actually works when you land in Japan
Japan has three main mobile carriers: NTT Docomo, SoftBank, and KDDI au. Verizon’s roaming partners route you to SoftBank as the primary network, with KDDI au as a fallback in some regions. NTT Docomo has the strongest rural coverage of the three, but no major US carrier (or major eSIM brand) routes Docomo-primary for tourists. For city trips — Tokyo, Osaka, Kyoto, Hiroshima, Fukuoka — the difference is invisible. You’ll pull 100+ Mbps on 5G in Shibuya and Dotonbori either way.
TravelPass auto-activates on first use. You’ll get a Verizon SMS confirming the day-pass charge. Days you don’t use the network aren’t billed — but your phone background-syncing email or a single iMessage notification counts as activation. Disable cellular data on landing if you want some quiet days, then re-enable when you actually need it.

The honest break-even math
| Trip length | Verizon TravelPass | Travelren 3GB / 30 days | Cheaper option |
|---|---|---|---|
| 1 day stopover | USD$12 | USD$8.20 | eSIM saves USD$3.80 |
| 3 days (Tokyo weekend) | USD$36 | USD$8.20 | eSIM saves USD$27.80 |
| 1 week | USD$84 | USD$8.20 | eSIM saves USD$75.80 |
| 2 weeks (typical Japan trip) | USD$168 | USD$13 (5GB) | eSIM saves USD$155 |
| 3 weeks | USD$252 | USD$18 (10GB) | eSIM saves USD$234 |
The eSIM is cheaper at every trip length, including a one-day stopover. There’s no Japan trip where TravelPass beats an eSIM on price.
When Verizon TravelPass is actually the right call
- You’re transiting through Tokyo for under 6 hours with a long Singapore or LAX layover before or after. Adding an eSIM you’ll use for half a layover isn’t worth the setup time
- You can’t have your US number go silent on data days for SMS reasons — bank 2FA, doctor calls, recruiter texts. Most modern phones handle this with dual-SIM (eSIM + physical), but if your phone can’t dual-SIM, TravelPass keeps your line live
- You’re on a corporate Verizon plan that comps TravelPass — some enterprise plans include international roaming. Verify with IT before assuming
- You don’t want to fiddle with QR codes on a 14-hour flight before landing tired. TravelPass auto-activates with zero config
Will your phone work?
Almost certainly yes. iPhone XS or newer (2018+), Pixel 3 or newer, Galaxy S20 or newer all support eSIM. As of iPhone 14 (2022), all US-sold iPhones are eSIM-only — no physical SIM tray exists. For Verizon-locked phones: Verizon unlocks phones automatically 60 days after purchase if the device is paid-off, so older devices on contract should be fine.
The exception: iPhones bought directly from Apple in mainland China don’t have eSIM hardware even when the model number is otherwise identical to a US-purchased phone. If your iPhone was bought in China, you’ll need to use TravelPass or a physical SIM in country.

Common questions
Can’t I just use airport WiFi to get a Suica card and Google Maps before leaving Narita / Haneda?
You can — and that approach gets a lot of first-time visitors through the day they land. But you’ll need data the moment you step outside the terminal: trains shut quickly after midnight, last-train alerts, restaurant reservations, Suica top-ups via the Apple Wallet pass. The cost of being disconnected for the 90 minutes between airport WiFi and your hotel WiFi is usually higher than USD$8.20.
What about pocket-wifi rental at the airport?
Pocket WiFi made sense pre-2020 when eSIM was still rare on US phones. Today it’s USD$60-100 for a week, requires you to keep a separate device charged, and has roughly the same coverage as your phone would have on an eSIM. The eSIM at USD$8.20 is the same product without the extra device.
Will iMessage and WhatsApp keep working on my US number?
Yes. Both are tied to your Apple ID / phone number registration, not the network. As long as you have data (from any source — Verizon TravelPass OR an eSIM), iMessage and WhatsApp keep working. Your contacts see your usual US number.
Can I make calls in Japan with the eSIM?
The Travelren Japan eSIM is data-only. For calls home: FaceTime, WhatsApp, Signal, or Google Meet over data. For calls to local Japanese numbers (your hotel, restaurant reservations) — most reservations in Japan happen over web (Tabelog, OpenTable Japan) or LINE, not phone. If you genuinely need to dial a 03 or 06 number, your hotel concierge can call for you.
My trip is 15 days but the 30-day plan ends on day 30. What happens after I leave Japan?
Nothing. The eSIM expires when you reach 30 days from activation OR when you delete it from your phone, whichever comes first. There’s no auto-renewal and no way for it to charge you when you’re back in the US. You can also delete it the moment you board the return flight.
The bottom line
For any Japan trip longer than a brief layover, an eSIM saves significant money over Verizon TravelPass. A typical 2-week Japan vacation: USD$13 with Travelren, USD$168 with TravelPass. That’s USD$155 you can spend on a memorable kaiseki dinner instead.
The eSIM does require 5 minutes of setup (QR code scan + plan activation) and means your Verizon number drops to SMS-only on data days. If those constraints don’t bother you, the math is clear.
