Ninja WiFi or Japan Wireless?

Hello!

Just as the header above, we’re wondering which between the two is better. We’re just two, and spending around a week in Japan―hope this helps in evaluating the choice.

Thanks!

It's not really about which company but which carrier they use. I normally use the Japan Wireless 99.9% coverage with unlimited bundle. I would not be surprised if both use the same package....

Hi, Liza3939.

I'm a Japanese working in Tokyo for over a decade.
If I were you and only have those two options, I would take Japan Wireless as Ninja WiFi has posted too much ads, and even worse, such ads have bad reviews.

And, as mfedley has already said here, I totally agree with his saying: It's not really about which company but which carrier they use.

For example, as for a pocket WiFi router, they both use SoftBank.
In that case, you are better off to check their credibility and support.

Lastly, I just will give you more WiFi options to compare more.

Hope you will have a great experience in your Japan travel.
