This November 2014 article claims that from December 2014 Tokyo Metro trains would have free WiFi.

Has it become a reality?
If yes, what are the modalities for using it?

Thanks @pnuts for the link that contains the information I was looking for:

Step 1: Select the “Metro_Free_Wi-Fi” or “Toei_Subway_Free_Wi-Fi” SSID on your laptop or smart device.

Step 2: Launch your web browser.

Step 3: Follow the instructions on the screen (you will be required to register your email address), and you will be connected to the internet. You will be able to use the internet for up to 3 hours each time you log in.

By using the “Japan Connected free Wi-Fi” app and registering your details, you do not need to log into each Wi-Fi access point.

WiFi is not available in trains, only in stations.
Actually, only a selection of stations:

    The JR stations also have free Wifi, which you'll cross pretty often :)

  • Just to note, ALL Metro and Toei Stations now have Wifi May 31, 2016 at 0:07

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.

    You may wish to note that Starbucks WiFi requires sign up from a web browser BEFORE you go the first time. Also that thinks like Japan Tourist WiFi are also possible to use (17000+ spots around the country). May 31, 2016 at 0:09
  • @TheWanderingCoder Well, now you can connect to Starbucks Wi-Fi using social accounts like Twitter or Facebook. As to other choices it gets astray from what OP was asking, which focuses on metro, so I didn't list them all. But now I found the list is available in English and thus I updated it.

  • Oooh they changed it. +1 Good to know. I have a contract for NTT Spot so I haven't used Starbucks WiFi in ages (Starbucks offer NTT Spot connections as well). Good to see they are starting to open up to not having to register for everything. May 31, 2016 at 5:45
