Two weeks in Japan, and the plan you bought ran out on day nine. Or the roaming bill landed after you got home. Or the “unlimited” eSIM slowed to a crawl somewhere between Tokyo and Kyoto.
Atlas, a small globe with a massive passport, has watched travelers buy data country by country for years. He’s unbothered, since he’s seen worse. You can be unbothered too. Fourteen days of unlimited data for Japan should cost one flat price set by trip length, not by country, so the same eSIM covers Japan now and every trip after.
How much does an unlimited eSIM for Japan cost for 14 days?
Our 14-day unlimited plan costs USD 27.99. The price is set by trip length, so it’s the same in Japan as in any other country: same price whether you’re in France or Japan.
That’s the rate card idea. Plans run 3, 7, 14 or 30 days, all with unlimited data across 165+ countries, and Japan doesn’t get its own price. The app marks the 14-day plan as Most Popular, and it’s built for holidays and two-week trips.
What does a 14-day Japan eSIM cost per day?
Divide the 14-day price by 14 and you get the real daily cost: USD 2.00 per day on our plan. Per-day is the fair way to compare a 14-day plan with a 15-day or 7-day one, because it turns mismatched plan lengths into one comparable line.
Our other tiers work the same way. The 3-day plan is USD 9.99, which is $3.33 per day. Longer trips get cheaper by the day, and none of it changes with the country you land in.
Hotspot is included with every plan, so the laptop on your lap doesn’t add a line to the bill. Pick your days and go.
What does unlimited mean on a 14-day Japan eSIM plan?
“Unlimited” only means something once you know the daily allowance. Every plan of ours includes a daily high-speed allowance, called the Daily Quota, at up to 4G LTE or 5G where local networks offer it. It resets automatically every 24 hours, and once you’ve used it, data continues at standard speed for the rest of the day.
Your data is never cut off entirely. Unused daily quota doesn’t carry over, so each day starts fresh. We state no daily gigabyte figure because the plans are priced by days, not by the gigabyte. Speeds after the quota depend on local network conditions, and no speed is guaranteed.
The refresh clock counts from your activation, so it usually won’t land at midnight. You can see your refresh time under the data usage bar in your account, shown in UTC.
Unlimited plans are made for travelers using data on the move: maps, messaging, calls over apps, a few hours of streaming a day. Huge file downloads, P2P uploads and using your hotspot as a router for multiple computers may be limited, and Wi-Fi is better for those. The Acceptable Use Policy has the full list.
What does a home carrier charge for two weeks of data in Japan?
Your home carrier’s roaming pass is priced per day, and a two-week trip means paying that daily price for each day you use it. AT&T’s International Day Pass costs $12 per day for a single line in Japan, and $6 for each additional line used on the same calendar day (AT&T, “Using your US cell phone in Japan,” att.com, 2026).
Our 14-day plan is one purchase of USD 27.99, which is $2.00 per day, covering the whole trip. The eSIM is data-only, so calling and texting aren’t included, but you can still browse, get directions and use your apps. It runs as an add-on to your main phone plan. Roaming data charges won’t be added as long as the eSIM is installed and configured correctly and Data Roaming is turned off on your regular plan.
Maya Mobile never charges roaming fees or other charges with its data plans.
What do travelers say went wrong with another travel eSIM?
Travelers report the same few things: no data on landing, a connection that dropped, an install that failed, and speeds that slowed. These are what a flat, always-installed eSIM is built to avoid.
Troy left a 2-star Trustpilot review on June 16, 2026 about slowed speeds, and the review’s closing advice was worth taking: “Read the fine print before buying.” Before you pay for any plan, find the daily allowance in writing. Ours is stated in our terms: the Daily Quota, then standard speed.
Install trouble is the other one to check. If there’s no data on arrival, confirm the Maya eSIM is switched on and selected for Cellular Data in your phone settings. Our plans activate in a minute or two, and the plan clock starts when you enable the eSIM, so you can install before you fly and switch it on when you land.
What does a Japan eSIM price leave out?
Our plan is a one-time purchase that ends when its days end, and Auto Top-Up is opt-in and off by default. There’s no subscription and no lock-in, and nothing charges automatically after the plan ends unless you turn on Auto Top-Up.
With Auto Top-Up enabled, you are charged automatically at each renewal, and you authorise that charge. You can turn it on at checkout or in the app, and off at any time. We give at least 30 days’ notice of any price increase for active Auto Top-Up arrangements.
Every plan is prepaid and paid at purchase. Prices are shown in USD by default, and if you pay in another currency your bank or card provider may add foreign exchange fees that we don’t control. If the eSIM can’t be installed or used, we offer a money-back guarantee, on the conditions in our return policy.

How Maya Mobile covers Japan and 165+ countries with one 14-day price of USD 27.99
We built Maya Mobile around the argument above: a two-week Japan trip shouldn’t be a price hunt. It’s a travel eSIM giving unlimited data in 165+ countries and 20+ cruise lines through a single eSIM permanently installed on your phone. You install it once, and for each trip you buy a plan from the app.
The 14-day plan is USD 27.99 in Japan and everywhere else. Next trip, the eSIM is still on your phone, ready for you to buy the next plan. One plan covers multi-country travel, so adding a country mid-trip keeps the same plan and the same eSIM. Need more days? Buy another plan from the app in under a minute.
The incumbents run stores. We built a switch. Flip it and go.
Frequently asked questions
How much data does an unlimited Japan eSIM include per day?
Every plan includes a daily high-speed allowance, called the Daily Quota, at up to 4G LTE or 5G where available on local networks. It resets every 24 hours. Once it’s used, data continues at standard speed for the rest of the day, and no speed is guaranteed.
Does a 14-day eSIM start when I buy it or when I land?
The plan clock starts when you enable the Maya eSIM in your phone settings. So you can buy and install before you fly, then switch it on when you want your days to start counting. A day is 24 hours from the moment your plan starts.
Can I use the same eSIM in Japan and my next country?
Yes. One plan covers multi-country travel, so you don’t switch SIMs when you add countries. The eSIM stays installed after the plan expires, and each new trip needs a new plan. Coverage in a specific country isn’t guaranteed and can vary for reasons outside our control.
What do I do if I need more than 14 days in Japan?
Buy another plan from the Maya app. The 30-day plan is USD 49.99, which is $1.67 per day. There’s no subscription, no monthly fees and no auto-charges unless you turn on Auto Top-Up.
Do I need an unlocked phone to install an eSIM for Japan?
Yes, your phone must be carrier unlocked. Apple Support (“Use eSIM while traveling internationally with your iPhone,” 2026) says an iPhone can’t be locked to a carrier to use another carrier’s eSIM. You can check under Settings > General > About, where “No SIM Restrictions” appears next to Carrier Lock if the phone is unlocked. Check your model at maya.net/esim-compatible-devices.
Does the plan include a hotspot?
Yes, hotspot is included with every plan at no extra cost, though we can’t promise it in every country. Using it for a laptop or tablet to join Zoom calls is regular use. Using it as a router for multiple computers may be limited.
Is an eSIM cheaper than a Japan pocket Wi-Fi rental?
Pocket Wi-Fi is priced per day too, so the per-day figure is the one to compare. NINJA WiFi lists its lowest published daily rate as 440 yen per day for its Unlimited Plan (SoftBank) with 1GB per day, and 1,980 yen daily on the Infinite Unlimited Plan, with sales tax included (NINJA WiFi, “Rates & Plans,” ninjawifi.com/en/plan, retrieved 12 October 2026). Japan Wireless’s 2026 price guide also lists Ninja WiFi from ¥440/day, with prices verified June 2026. Our 14-day plan is $2.00 per day.
Maya gives you unlimited data in Japan on one flat 14-day price of USD 27.99, with the same eSIM staying on your phone for every trip after.
