Here are some links for how to get to NII

The main entrance of NII is closed on weekends and public holidays, and after 10pm on weekdays.  On these days you need to use the 24 hour entrance.






Getting here from the airport

There are two train lines connecting Narita airport to the center of Tokyo: The JR line and the Keisei line.  Each have express services
(Narita express, Skyliner respectively), but these are more expensive (double or triple), so unless you are in a great rush catching the cheaper local services is not a bad option.  Even if you are in a rush, the Keisei Skyliner is cheaper  and faster than the JR so its probably the one to catch.

There are many ways of getting to Jimbocho due to the many lines available. To find the best way for you, first go to the train access page “Jorudan”.

Then enter

From: Narita-Airport

To: Jimbocho

Seat: Unreserved

The precise way to getting here depends on the time, but for the cheaper way expect to pay 1200 yen, and 2500 yen for the faster service. The faster way should take about 1 hour total, while the cheaper way should take about 1.5 hours.

A common route is a change at Keisei Yawata/Motoyawata. Keisei Yawata and Motoyawata are geographically in the same place, but
are run by different companies, explaining the difference in the names.  Its still a bit out of Tokyo so its not going to be where
everyone is getting off but it happens to be the easiest route to get to NII.  Trains in japan usually run exactly to the minute, so there
is a pretty good chance you can tell where you are by just looking at your watch.

Once you get to Jimbocho, then head to exit A8.  Following the above maps and directions, it should be a few minutes walk to NII.  Good luck!
