I often use Narita Express when going and coming back from Narita airport(NRT), I just found out that there is Wi-Fi service recently ^^;

In addition, it was just in front of my eyes.

I’m surprised that I didn’t notice it before…

Let me use the excuse that I have been busy looking after my son^^;

How to connect to Wi-Fi

You can select ‘JR-EAST_FREE_Wi-Fi’ SSID.
　
After connection, the following page will be displayed.

Click(tap) ‘Access the internet here.’.

Fill in your email address.

Click(tap) “I agree”, then the following page will be displayed.

It will be done!

Speed

Uploading : 0.97Mbps
Downloading : 1.99Mbps

It was not that bad, unlike the numbers show.

Conclusion

Mind you it will be disconnected quite often which might make you irritated.

Especially when going through the tunnel.　

You have to connect again.

The one in Hong Kong is better.

JR should visit there and learn from it.
