About Us
We rent pocket WiFi routers and sell eSIMs, so we have no reason to push you to one or the other. Here is how they actually compare for a trip to Japan, and a simple rule for choosing.
From 2,480 JPY for 6 days / 20GB. Emailed in minutes.
From 610 JPY per day, unlimited. Same-day delivery in Tokyo.
| Pocket WiFi (rental) | eSIM (data plan) | |
|---|---|---|
| Data allowance | Unlimited — no daily cap, no throttling | Fixed quota (20–135GB). Slows down after the quota |
| Number of devices | Up to 10 phones, laptops, tablets, cameras | 1 phone (tethering allowed but drains the phone) |
| Phone compatibility | Any device with WiFi, locked or unlocked | Unlocked, eSIM-capable phone only |
| Setup | Switch on, enter the WiFi password printed on the device | Scan QR code, add the line, enable data roaming for it |
| How you get it | Delivered to hotel / Airbnb / airport. Same day in Tokyo, 3-hour express in the 23 wards | Emailed within minutes, install before you fly |
| Returning | Drop the prepaid envelope in any post box by 8am after your end date | Nothing to return |
| Battery | About 13 hours; needs charging (charger included) | Uses your phone’s battery; hotspot use drains it fast |
| Network | SoftBank 4G LTE / WiMAX +5G, nationwide | docomo 4G/5G, nationwide |
| Japanese phone number | Available with a rental phone or Talk SIM | No (data only) |
| Price (example) | 7 days unlimited, 1 device: 4,550 JPY + 1,200 JPY shipping For a couple sharing: same price, so about 2,276 JPY each | 8 days / 30GB: 3,280 JPY per person For a couple: 6,560 JPY |
| If it breaks / doesn’t work | Replacement delivered by the next day (3-hour express available in Tokyo / Osaka for an extra charge) | Re-issue by email; depends on your phone |
Prices as of October 2026, tax included. Pocket WiFi rental includes damage insurance and the prepaid return envelope. eSIM plans and prices: see all plans.
For a solo traveller with a modern phone, the eSIM wins on price and convenience. A 6-day 20GB plan costs 2,480 JPY, you install it at home before departure, and there is nothing to charge, carry or post back. Twenty gigabytes covers a week of maps, translation, messaging, social media and a fair amount of video for most people. If you are a light user, go eSIM and don’t overthink it.
It is also the right choice if you land late at night or arrive somewhere we can’t deliver the same day, because it works the moment your plane lands.
The maths changes as soon as a second person appears. One pocket WiFi at 610 JPY per day connects everyone in the family, so for a couple or a group it usually costs less per person than eSIMs for each phone, and nobody has to fiddle with their settings. It is the only option for a phone that is carrier-locked or too old for eSIM, which is still common.
The bigger reason is data. eSIM “unlimited” plans in Japan almost always mean a daily cap followed by slow speeds; our pocket WiFi has no cap at all. If you work on the road, upload photos and video, stream in the hotel or run a laptop off your connection, you will feel the difference by day three. Add a rental phone or Talk SIM and you also get a Japanese number for restaurant bookings and deliveries, which no data eSIM provides.
Plenty of our customers do: an eSIM on the phone for the moments you step away from the group, and one pocket WiFi for the family, the laptop and the heavy lifting. If you order both from us, the eSIM is emailed immediately and the router meets you at the hotel or airport.
| Your situation | Our recommendation |
|---|---|
| Solo, recent iPhone/Pixel/Samsung, normal use | eSIM |
| Couple or family sharing | Pocket WiFi (one device for all) |

| Locked phone or no eSIM support | Pocket WiFi or physical SIM |
| Need a Japanese phone number | Rental phone or Talk SIM |
| Stay of 2 weeks or more in one apartment | Plug-in home router |
| Arriving today and need internet now (Tokyo 23 wards / Osaka) | Pocket WiFi, 3-hour delivery — or an eSIM if your phone supports it |
