Offering You The Most Reliable and Reasonable Data & Phone Services

Pocket WiFi & SIM Card Rental Service
For The Best Japan Travel Experience Ever!

LightPocket is a Tokyo-based company established to solve one big issue facing visitors to Japan: Unstable internet connections.

When traveling to Japan, a majority of people finds that they cannot easily get connected with the internet.
Although the number of public WiFi spots are increasing, they are still insufficient in terms of security, stability, data limits, throttling and communication speed. The choices are very inconvenient, even for locals.

Don't let yourself be captured in such a cage, and escape from the stress of poor internet services.
To stay easily and reasonably connected when you travel around Japan, how about renting a superior pocket WiFi router or a data reliable SIM card?
LightPocket provides high speed and stable data communication services with proven reliability.

If you are considering renting a pocket WiFi or buying a SIM card directly at the airport after arrival, unfortunately, chances are you can not always rent/buy it because their stock inventory at airport shops is limited, and they often run out, especially during peak seasons (March, April, November, December). When you arrive in Japan, you may find yourself in a long line, for a long time, just to get pocket WiFi or a SIM card.

Don't let yourself be victimized. Stay focused on your invaluable Japan travel experience.
With LightPocket service, all you have to do is just pre-ordering a pocket WiFi or a SIM card online.
You can have it sent anywhere with a deliverable address, including post offices in the airport, your hotel, or at your residence/Airbnb.
Also, you can return it from anywhere in Japan. Furthermore, our prices are much more reasonable than renting at physical stores in airports.

Delivery Guarantee: If you are concerned or unsure of your Japanese address which you specified as a pickup point, don't worry. Our team at LightPocket will check and confirm it, and revise if needed. If you forget to pick up your pocket WiFi or a SIM card at the airport, don't worry. LightPocket can transfer it to a new address.

Quality Guarantee: If you find that your device is not compatible with our products or the signal or strength is poor, don't worry. LightPocket will issue you a refund.

Extension and Return Guarantee: You can easily extend the rental period, and returning products is always free of charge with our postage-paid return envelope.

Japan Pocket WiFi Rental

Stay fast and connected all around Japan. If you are visiting Japan with your family or friends, or are staying long in Japan, renting a portable WiFi router is your best choice. One pocket WiFi supports simultaneous multiple device connectivity.

All our Pocket WiFi routers have good coverage throughout Japan, covering more than 95% of the population, so coverage and connectivity should not be a problem anywhere you go in Japan.

Japan Data SIM Card Rental

A data SIM card is useful for mobile phones or tablets. Other prepaid SIM cards will leave you high and dry when the data limits are reached. LightPocket SIMs stay fully connected during your rental period, as there are no caps on data usage.
You will be satisfied with the high-speed internet communication through the SIMs we offer. Even if you exceed the daily data limits, don't worry, you still have internet access at 256Kbps, which enables you to use essential apps such as Google Maps.

Furthermore, even if you reach the daily data limits, the speed limitation will be lifted the following day, while other rental providers keep you waiting up to several days before they lift the restrictions. We manage the data communication of our service on a daily basis to ensure high-quality for you.
Along with our SIM, we also provide you a with a complimentary SIM card holder and an ejection pin to insert the SIM into your device.

Why did we select rental SIMs for our business, and not prepaid ones?
Because we never want to make our customers feel disappointed whatsoever.

Prepaid SIMs seemingly looks convenient as there is no need to return them. However, many prepaid SIMs don't fit, don't work in your device, or malfunction soon after purchase. Prepaid SIMs cannot be returned so you lose your purchase costs, and then you need to buy another.

Major reasons for disappointment are:
Your device does is not compatible with the frequency bands in Japan.
Your device is completely locked.
Your device is unlocked for SIM use, but is locked regionally .
You ordered the wrong SIM card size.
Poor connectivity at places where you stay or go.

It is very difficult to check each of these conditions before you actually arrive in Japan.
However, once you purchase a prepaid SIM, you cannot get a refund for any reason, even if the SIM did not work.
You will end up really disappointed. This is not a rare occurrence; the number of people getting caught in this situation are increasing all the time.

Therefore, LightPocket chose not to sell prepaid SIMs, but decided upon rental SIMs instead.
We accordingly can support you if you experience any of these troubles, and promptly issues a refund if needed.

No Waiting Time/Easy Return: Pocket WiFi

If you reserve your SIM or Pocket WiFi with one of our competitors, you start the process of renting after you arrive at the airport. Don't do that.
It could be take a long time, and it might end in vain if they are out of stock, especially during peak seasons.
If you pre-order online through LightPocket, you can pick it up or have it delivered anywhere you want such as the airport, your hotel, or your residence.
Also, you can return it from anywhere in Japan just by dropping the postage-paid envelope into any mailbox located all over Japan. For no additional fee, of course.

Unlimited Data Pocket WiFi/SIM Card

If you rent an unlimited Data Pocket WiFi or SIM from LightPocket, there are no limitations for data usage overall. But please note that your data speed may also be limited if you routinely exceed your allotted data, which varies depending on your plan. However, you can still connect at 256Kbps, which enables you to use essential apps such as Google Maps. Data limitations will be lifted at 0:00 the following day.

Communication Network: Great Stability and Large Coverage

LightPocket provides pocket WiFi routers and data SIMs using NTT DoCoMo and SoftBank networks. Both networks are highly-acclaimed for its great stability and nationwide coverage.

About SIM Card in Japan

In Japan, SIMs with voice call functionality are strictly regulated to prevent crime by use of unidentified and unregistered phone numbers. Obtaining such a SIM card by international travelers or people who stay in Japan for a short period of time is almost impossible. Even if you are able to find one, it will be very pricey. Although there might be some exceptions, they are not recommended. Therefore, a data SIM card without voice call functionality will be the only SIM for visitors to Japan. Of course, even with a data SIM card, you can still use VoIP apps such as IP phone, FaceTime, and Skype to make calls, as they are not regulated.


Worked excellent. I used two phone and they worked very well in all places visired (e.g. Tokyo, Kyoto, etc.) including during hiking in mountain trails. Thanks. Mostly use it for maps, reservations, skype calls, youtube, etc.

This service worked perfectly for me - it was especially helpful to be able to send the package to a post office rather than a hotel address. The device worked well consistently and was invaluable during my trip.

All in all I was very happy with the service. I had no problems with delivery and the simcard worked perfectly. The only drawback I experienced was that the instructions were not extremely clear on how to adjust my phone (iphone) to have the mobile network details (APN details) setup. It did not say I should download the profile details while connected to Internet from another network (possibly a Wifi). I strictly followed the instructions, so I replaced my simcard but I could not download the profile (as my mobile network was not setup properly at that moment). It took me quite a long time and many attempts until I realized that I perhaps try downloading the profile over wifi. I almost returned the simcard for that. I strongly suggest you make this detail clear in your otherwise quite clear instructions.

I had an excellent experience with lightpocket. Our pocket wifi was at the post office when we arrived and the return was very easy. The pocket wifi battery lasted a full day and we never had any problems with it. Highly recommend.

Everything was perfect. The hotel clerk gave me the package and the connection was easy with the data sticked on the back of the pocket. The return was simple with the prepaid envelope that was in the package. I'll probably use this service again in the future.

The light pocket WiFi was well worth having on our trip round Japan. There wa much more WiFi available than we expected in hotels and in some towns but a number of times we found ourselves needing information or translation when none was available. For example we were able to book a hotel and car while travelling on a train. Some trains had WiFi but not the Shikansen, surprisingly. Our Japanese grinds also found it useful to hook up to. We would recommend this service which was efficient and good value. Easy to return and we had it delivered to our friend’s house.For us it was better than having a sim as our phones only take one card.
