In The U.S with a strong IT industry, there are Wi-Fi spots installed in many public establishments such as restaurants, shopping centres and more.
However, for those who think that whatever country they visit, there would be places equipped with free Wi-Fi, might find the opposite when they visit Japan.

Despite being a developed country, compared to other developed countries in the world, it is said that Japan is behind with establishing Wi-Fi spots in many public spaces. According to a survey taken by tourists in Japan in 2016, the 2nd biggest problem while travelling was said to be the lack of free Wi-Fi spots in public places.

The following guide will introduce free Wi-Fi spots in Japan as well as inform you of how to safely connect to them.
