Pros and cons
Ninja WiFi
Pros
- Daily price of ¥440 keeps a short Japan trip easy to budget.
- Unlimited data is on offer, listed as the unlimited data feature, and the capped plans slow down past the daily cap.
- Pickup at airport counters or courier delivery to your hotel, with a counter, courier or airport return box for the return.
Cons
- Support runs on phone and help centre only, with no chat or email listed for questions on the ground.
- Unlimited data comes with strings: past the daily cap the speed drops, and very heavy use in a day can suspend the service, with a fair use policy that says Excessive use may cause reduced speed.
- It is built for a single market, with JP as its home country, so it does not stretch beyond Japan.
Unidata
Pros
- Daily rental at $5.99 keeps budgeting clear for groups sharing connectivity costs across companions
- Allowance of 3GB per day supports maps, messaging and streaming without hunting for cafe WiFi during outings
- Support for 10 connected devices lets family members stay online together from a shared hotspot
Cons
- Rental at $5.99 may feel steep across extended stays compared with Klook Japan SIM/eSIM at $1.05 for light phone use
- Allowance capped at 3GB per day means heavy streaming across 10 connections can use shared headroom quickly
- Fulfilment via Ships to address needs planning for delivery and return, unlike Cherry Roam pickup options for quick handovers
Who each suits
Ninja WiFi
Who it suits
- You land in Japan and want a device in your bag the same day, with airport counter pickup or courier delivery to your accommodation.
- You browse, stream and map all day and want unlimited data, with a daily cap you can live inside.
- You travel solo or as a pair, since the device handles 2 devices at once.
Who should look elsewhere
- WOM Chile, listed at CLP 3,990 a day, fits a Chile trip better than a Japan-only device.
- QCell, whose roaming data packages cover 50MB to 2GB per roaming data package, suits a traveller who wants data across markets rather than one home country.
Unidata
Who it suits
- Groups who prefer shared pocket WiFi over separate Cherry Roam units for phones and laptops together
- Families needing 10 connections with 3GB per day rather than Econet Telecom Lesotho options built for other regional travel
- Planners who value advance shipment via Ships to address over Klook Japan SIM/eSIM handling for quick solo activation
Who should look elsewhere
- Solo light users who would find Klook Japan SIM/eSIM at $1.05 simpler than carrying and charging a shared hotspot
- Travelers wanting instant counter pickup rather than Unidata fulfilment via Ships to address, where Cherry Roam handling may feel more direct

Questions about each
Ninja WiFi
How much does Ninja WiFi cost per day?+
Plans run at ¥440 a day, with the entry point quoted at ¥770. Unlimited data sits inside the range rather than being sold as a separate data top-up, so the daily rate carries the whole cost. Pick the plan length that matches how long you are in the country.
Is the data allowance really unlimited?+
Unlimited data is listed as available, and it shows as the unlimited data feature. The catch sits in the allowance: the capped plans reduce speed once you pass the daily cap, and use beyond a very heavy daily total may suspend the service. So read unlimited as generous rather than endless.
Unidata
How much does Unidata pocket WiFi cost?+
Daily rental is priced at $5.99. The charge covers shared hotspot use for the rental period, which helps groups split connectivity costs instead of buying separate plans for phones, tablets and laptops during sightseeing.
What data allowance is included?+
The Japan plan includes 3GB per day. That allowance covers maps, messaging, browsing and video calls during active travel days, though simultaneous streaming across many screens will draw down the shared pool faster than casual browsing alone.
