Connecting to the global world within a few swipes has made it easy to explore the world. The more often we connect to the internet, the easier exploring the world and meeting new people becomes. Traveling or living in Japan will be the easiest thing if you know the best applications to make use of. Please check it out from this article!

Is Free Public Wifi Still Hard to Find in Japan?

The most important thing is you must connect to the internet while using those useful applications. My friends and my relatives asked me many questions about the data internet in Japan before they went to Japan. Most of them were worried about connecting the internet. They were afraid of getting lost or could not find the place where they wanted to visit because everyone knew that train line in Japan is crazy complicated and difficult to reach the destination, but it is also very convenient (if you know how to use it correctly).

Thus, What is the best choice between ‘Renting the pocket WIFI’ or ‘Buying the Data sim card for an individual smartphone’?  I dare say ‘Forget about it! You can use free WIFI around Japan without wasting your money’ You can save money from renting the pocket WIFI or buying the Data sim card for shopping or traveling to far areas.
This article will help you to connect to the internet for free easily. I will show you how can my friends and I survive in Japan without renting the pocket WIFI or buying the Data sim card. Let me show you ‘How to connect to the world (for free)’. I categorized free wifi spots into six topics based on places and searching free Wifi applications.

What are the Problems with Using Free Public Wifi in Japan?

There are, however, some downsides to Japanese free wifi that users have to face.

1. You can not be connected online all the time and respond texts in the real-time in a lot of cases.

For a social person who always updates your own story on Instagram, keeps posting on Facebook or loves to tweet every other minute, you may feel like it’s more of a  waste of time to find free Wifi spots and repetitively have to log in. But, it IS free!

2. The public free Wifi is very slow and unstable.

If you are in an urgent, you have to access the internet and get necessary information during your travel. This problem can be easily solved by being prepared on the day before you travel.

3 The security risks that come with using an unsecured network

This is the main problems about connecting to the free Wifi. In the case that you have to use the internet to access essential things like making last minute hotel reservations or money transfers. I recommend that you should rent the pocket wifi or purchase a data sim card. The selection between renting the pocket Wifi and buying a data sim card depends on the amount of cellular data you plan on using. The pocket wifi can be used with many devices, and it is fast enough to make use of the navigation apps or watching VDO clips, whereas the users have to stay close to the pocket Wifi and frequently check to make sure the battery isn’t about to die. The data sim for an individual device is also the best choice for traveling alone or for everyone who is afraid of getting lost from each other. The users do not have to worry about the battery during connecting the internet while the data is limited and is a bit slower than the pocket wifi. 

I hope this article will help you travel in Japan, and make things a little easier to navigate through after taking advantage of the free public wifi!
