In addition to the answer by @nic, you can also use JR-EAST FREE Wi-Fi
at some JR stations, and TOBU_Free_Wi-Fi
at some Tobu line stations. This also requires you to register the service using email, for your information.
The official documentation is the following:
JR, available at Japanese, English, Korean, and Simplified and Traditional Chinese.
Tobu, available at Japanese, English, Korean, Thai, and Simplified and Traditional Chinese.
Also, you can see a list of available free Wi-Fi beyond the stations, including airport and bus station and some major cafe like Starbucks here.

register your email address), and you will be connected to the
