Internet Access and Electrical Equipment
In Japan, Free Wi-Fi is NOT available in every street. If you want Internet access anywhere in Japan for convenience, please go down this page to Rental Portable Wi-Fi.
The government is preparing better Internet environments for international tourists now. More and more tourist spots and shopping centers are starting to offer free Wi-Fi to attract people.
Most hotels offer Internet access in the guest rooms and the lobby. Check how to connect and whether it is free or not, before you make a reservation.
The international airports such as Narita and Haneda (There are 2 international airports in Tokyo. For details, go to this page.) provide free Wi-Fi. Your devices can connect to "FreeWiFi-NARITA" / "HANEDA-FREE-WIFI".
The major stations of JR East, such as Tokyo, Ueno, Shinjuku, Shibuya, Harajuku, Hamamatsucho, Akihabara, etc, provide free Wi-Fi.
It is quite easy to connect. No special setting required. Your e-mail address is necessary only for the first time.
The following PDF file about where exactly the service locations are and how you can connect is written in English, Chinese, Korean and Japanese.
Tokyo Metro (Subway) Stations
Many subway stations offer free Wi-Fi service with just your e-mail address. If it is a big, major station, you will be able to use free Wi-Fi for sure.
To connect your devices, you go to the Wi-Fi spot of the station, select “Metro_Free_Wi-Fi” / “Toei_Subway_Free_Wi-Fi”, open your web browser and register your e-mail address.

Many stores offer Wi-Fi service and I often see international tourists with a laptop and a drink.
