What is Pocket WiFi?
A Pocket WiFi is a small mobile device that provides a WiFi network. It is also called WiFi router or portable WiFi. You can easily connect your phones, tablets and laptops to the Pocket WiFi or even share hotspot with more than 5 people at a time.
Why do I need a Pocket WiFi in Japan?
Unlike many other developed countries, Japan is infamous for its lack of extensive free Wifi in public places. It is particularly hard to find free internet in Japan. In fact, even when you are able to connect one, the internet speed is too slow for you to do anything, not to say uploading nice pictures on social media. Without any internet access, you would be really frustrated during the trip. Renting Pocket WiFi in Japan is pretty convenient. If you are traveling to Tokyo, you could easily rent your Pocket WiFi in Tokyo.
Besides, most WiFi router rental in Japan provide 4G unlimited services without throttled speed.👍🏻Compared to SIM card and data roaming, you get more data for watching videos, uploading photos, and using Skype. Thus, rather than trusting slow, unreliable Wifi in public areas, many travelers prefer to rent a mobile hotspot to ensure they stay connected throughout their travels in Japan.

In this article, we will list out some of the best portable WiFi rental in Japan.⭐️⭐️⭐️
Rental rates, data usage amount, battery life, and pick-up and return locations are compared under the same condition listed below:
- Pick-up Location: Airport
- Rental Term: 5 days
- Option: Extra mobile battery
From the comparison, we found out top 3 Pocket WiFi brands, Japan Wireless, Pupuru, and Japan Roaming. Personally, I would recommend Japan Roaming to tourists because it has the longest battery life among three of the cheapest ones. Battery life is really an essential spec when it comes to renting the best portable WiFi in Japan. Besides, Pocket WiFi from Japan Roaming can be doubled as a portable battery and a built-in real-time voice translator. Although the device itself can only be connected to 5 devices, I think overall Japan Roaming still stands out as the best option for wireless router in Japan since most people wouldn’t share hotspots with too many people at once.
