The NFL Game Pass is still the best way to legally watch NFL games from Japan. It is only available to people living outside the US, costs 27,415 yen, and lets you watch on computers and devices as well. If paying nearly 300 US dollars to watch the NFL seems a bit steep, it might be a good idea to find some friends to share the service with and split costs. Here is a screenshot of the details for this year.
An added bonus over years past, as you can see in the screenshot above, is access to NFL Network Live. This is especially good for the kind of fan that wants to watch all the teams and all the commentary. I haven’t seen it yet, but the condensed games also seem like an interesting way to save time when watching games you are less interested in.
This service also works if you are in other countries than Japan, and if you happen to be in the US and want this for some reason?… I recommend using a free or inexpensive VPN to get access by making it seem your computer is outside of the US.
