Good and necessary service

Positive: the pocket wi-fi has been effective end lasted for almost the whole day, before charging it. Very easy to understand and to use.
Very useful your suggestion to reset, as, one time, the system stopped working. Negative: as we arrived in Haneda International airport we had to move to another terminal, very far and that could only be reached by train, to get, at the Post Office, the envelope containing the dispositive.

Amazing experience!

From start to finish we had a great experience using this WiFi device. Easy pickup and startup. Good service the whole trip including underground and at the Disney Parks. Super easy drop off. Would definitely use again when we come back!

Fantastic service

We asked for the wifi to be delivered to the hotel and it was there on arrival. It had very clear packaging and instructions, was very reliable and had very good battery life. The return was very easy and I would definitely reccomend and use this service again. Thank you so much econnect:)

Super helpful, great speeds!

Was super helpful our entire trip! Google maps loaded very quickly and even let us watch some shows before bed one night when the hotel wifi wasn't covering it! We didn't have it for our entire trip and we definitely regretted turning it early! Our normal data plan got us around, but having the wifi just made the experience much better overall! Price was also super reasonable!

Great pocket wifi!

The pocket wifi was amazing very responsive and had fast internet everywhere I went even on top of Fushinari Shrine. My only complaint is that if you let it go lower then 1/5 in power it would not turn on again until you charged it to 1/2 way.

We are, family of 5, liked the easy way to get connected with all our devices across Japan. It was so good and the best way especially when you are from a western country.

No problem

When I arrived to Japan, the recepcionist of my hotel said that he didn't received the device, I send an email to econnect and they answered me right away, giving me the info to give to the hotel and in the end the device was found. Excellent exchange regarding client support. The device work perfectly and the battery of the device worked all day long without shutting down. Very good connection and internet. Nothing to say. Thank you!

Data Cap

We often get questions about data cap and unlimited data plan availability.
As explained in our blog post, every Pocket WiFi in Japan has a monthly data limit at some point where the internet speed is severely restricted under the Fair Usage Policy.
Even if you found a Pocket WiFi labelled as Unlimited Data, you should not assume that you could use data unlimitedly without any speed restrictions because you cannot.

At eConnect Japan, we set 1GB * rental days for the default data allotment which we guarantee that you can use without any possible speed restrictions.

We believe this data allowance is more than enough for normal travel use but we can add extra GB upon request for those who are in need.

Tips: use hotel wifi or other wifi when you download or upload large files.

Bonus: Order now and get extra 10GB data for free!

What's the speed like?

You might wonder how fast 4G speed would be. Our 4G model is definitely one of the fastest in Japan, the country ranks high in mobile internet speed. We have not heard any complaint about its speed.
So be assured that your internet experience will be comfortable and smooth.

Having said that, it's important to note the figures for both download and upload in the specification above are the theoretical ones at best effort. In the actual use case, the speed will be as not high as those numbers because you are not the only one using the network at any given time. Since the mobile network is shared with many users, the traffic that can go through at a time is limited. Simply put, when more people using more data, the speed will not go that fast.

Precaution Statement for the Pocket WiFi Rental

  • The connection speeds shown above are provided on best effort basis.
    Actual speeds vary depending on location and connection status.
  • Network provider (Softbank) reserves the right to restrict the connection speed for those who have used significant amount of data in a short period of time (or for those whose network activities are considered as suspicious).
  • Your device must be WiFi enabled.


It is the day we ask you to post the rental items back to us. You can simply drop it in any post box in Japan. We request that you do so by midnight on your return date.

You do not have to worry about how long it will take to get to us as long as you post it in time.

Once your data consumption reaches your total data allotment, it is subject to speed restriction from the network operator.
The network operator does not disclose when (or in what cases) the restriction applies or how slow it will be under the restriction.

Please be assured that the internet connection won't be cut off.

It depends on our data pooling status at the point of your purchase request. It might be possible in most cases but we cannot guarantee.

Please email us atinfo@econnectjapan.comif and when you need additional data.

With the extra portable battery we provide, it normally lasts for a whole day.

However, it really depends on how often and how long you use the device.

It comes with a SIM card inside as a unit. You do not have to buy anything extra.
