Wanderly Japan eSIM: a profile from the team that runs it

We’re run by the team behind Wanderly and earn money from Wanderly purchases. Read our full disclosure.

Read this first: we own Wanderly

Wanderly and eSIM Japan Guide are run by the same team, and we earn money when you buy a Wanderly plan. This page is not an independent review. It sets out Wanderly’s Japan plans and terms in the same way we describe other providers, says what we have not verified, and names the trips where another provider fits better.

Our ownership and affiliate disclosure explains the relationship in full. The same comparison rules apply to Wanderly as to every other provider: prices come from its public Japan page, recorded with the date we checked them, and our methodology explains what we do and do not test.

How to compare Wanderly’s fixed-data prices

Our Japan eSIM comparison compares packages covering the same requested duration. Wanderly’s Japan plans start from $2.99, and its 50GB plan valid for 3 days works out at $0.44/GB. Neither figure establishes the lowest complete cost for a longer trip: compare a package that covers your own dates and allowance.

Some matched examples from our data:

• A one-week trip: 10GB valid for 7 days costs $7.99.
• Two weeks with heavier use: 30GB valid for 15 days costs $17.99.
• A month: 20GB valid for 30 days costs $12.99.
• A long stay or repeat visits: 50GB valid for 180 days costs $39.99.

Low prices are not the same as a better connection. This profile uses published plan specifications, which do not establish a faster or more reliable connection than another provider.

Check Wanderly’s Japan listing →

On November 5, 2026, Wanderly’s Japan page said it lists 35 fixed-data plans, from 500MB to 50GB over 1 to 180 days, and that 14 of 44 Japan data-only plans can be topped up. The same day’s public catalog feed matches that count once the pieces are separated: 34 paid fixed-data plans, one free 500MB app claim, five day passes and four separate 999GB listings. This table records the 34 paid plans, from 1GB to 50GB and from 3 to 180 days, plus the starting day-pass price. It does not turn a day-pass price into a multi-day package. Validity sits beside every allowance because a cheap plan that expires before your flight home is not a saving. If you are unsure how much data you need, the Japan data calculator suggests an allowance for your trip length and habits.

The 5GB plan for 5 days now costs $4.99, and the 2GB plan for 15 days costs $3.99. New paid rows since the earlier catalogue check are 12GB for 4 days, 21GB for 7 days and 15GB for 30 days. Skip the 15GB 30-day plan: at $30.99 it costs more than the 20GB ($12.99), 30GB ($18.99) and 50GB ($25.99) 30-day plans, and our plan picker never selects it.

What Wanderly’s Japan page says, and what it leaves out

These terms were checked on November 5, 2026 against the Japan destination page and the public catalog feed. They are not one rule for every plan. Read the plan you select.

• 5GB for 7 days. The selected 5GB 7-day plan is data-only. It lists NTT Docomo and IIJ, starts on first network connection, says hotspot is supported, and says top-up is not available. It does not say that every other Japan plan works the same way.
• Network. The 5GB 5-day plan also lists NTT Docomo and IIJ. The 2GB 15-day, 10GB 30-day, 12GB 4-day and 21GB 7-day plans we opened list 3G/4G/5G and do not name an operator. Catalog names for the 12GB 4-day and 21GB 7-day products include KDDI, but those opened panels do not, and they say to ask support if you need a particular operator. Our guide to Docomo, SoftBank and au is about the networks, not a test of these plans.
• Activation. Each plan we opened (5GB for 7 and 5 days, 2GB for 15 days, 10GB for 30 days, 12GB for 4 days and 21GB for 7 days) says validity starts on first network connection. The Japan page, and Wanderly’s activation guide, say other plans can start when the eSIM is issued after purchase, when it is installed, or only if it is installed at the destination. A first-connection rule on one plan is not permission to install every plan before you fly.
• Hotspot. Supported on the 5GB 7-day and 5GB 5-day plans. The 2GB 15-day, 10GB 30-day, 12GB 4-day and 21GB 7-day plans say to check plan terms. That warning is not limited to plans with top-ups: the 21GB 7-day plan cannot be topped up and still says to check hotspot terms.
• Top-ups. The page’s 14 of 44 count matches the catalog: nine paid fixed plans, including 2GB for 15 days and 10GB for 30 days, plus five day passes. The 5GB 7-day plan cannot be topped up. If it runs out, you need another plan.
• Calls and texts. The opened fixed plans above are data-only. Calls and texts depend on the selected plan; our Japanese phone number guide explains what to check before relying on one.
• Day passes and 999GB listings. Day passes start at $2.99/day. The catalog row at that starting price is 1GB per day, then 1 Mbps, not an uncapped pass. The duration lists also show separate 999GB plans for 3, 5, 10 and 15 days, each with its own total. This comparison does not price those as the day-pass rate multiplied by the number of days. Our unlimited data guide explains why “unlimited” rarely means unlimited full-speed data.
• Free 500MB. The bottom of the fixed-plan range is a free app claim for first-time users, not a paid checkout row. Eligibility is in the app.
• Refunds. The opened plan panels say eligibility depends on the plan and its activation status, and they say to contact support before installing or using the eSIM. The refund policy, updated November 5, 2026, says a request may be eligible within 14 days of purchase if the digital product has not been fully delivered or accessed, and that immediate delivery can affect withdrawal rights. Nothing there promises a refund after the selected plan has been installed or used.
• Installation. Use the installation guide (updated November 3, 2026) and the help center. Install on reliable Wi-Fi at the time and place the selected plan allows. Some plans can be installed before departure; others must be installed at the destination. Check the phone is unlocked and eSIM-compatible before buying.

What to confirm before buying

Check the selected plan, not the brand:

• Which operator or network type that plan lists, and whether you still need to ask support.
• Whether validity starts on first connection, at issuance, or at installation, and whether installation has to wait until you are in Japan.
• Whether hotspot is supported or the plan says to check its terms.
• Whether a top-up exists if the allowance runs out.

This profile does not include a speed or coverage test. A listed network is not a measurement of service on your route. Buy a plan that covers your dates and allowance, follow that plan’s installation timing, and confirm data before you depend on it.

When another provider is the better choice

Wanderly is not the right answer for every trip, and these are the cases where we would point you elsewhere:

• You want a multi-day unlimited plan you never have to think about. Compare Holafly’s unlimited-only packages in our Holafly Japan review, and Saily’s in our Saily review, including their daily full-speed and hotspot limits.
• You need a Japanese phone number. Sakura Mobile and Mobal sell voice eSIMs with a Japanese number for visitors, both with ID checks. See our Sakura Mobile and Mobal reviews.
• You are a group staying together, or your phone has no eSIM. A rented router may suit you better; our pocket WiFi guide covers prices and pickup.
• You want a recurring monthly plan for a long stay. Ubigi’s monthly plans are covered in our Ubigi review.
• You already manage travel eSIMs in another app. Convenience is a fair reason to stay with a provider you know, such as Airalo; see our Airalo review.
