Access to RIKEN:
Note that an airport bus from Narita to Wako is not operated.
There are two ways to come from Narita to Wako:
Option A) Airport bus from Narita to Ikebukuro then train from Ikebukuro to Wako.
(1)Take off the bus at the last stop in Ikebukuro west gate.
Option B) Train from Narita to Wako.
[Narita airport] – ( Keisei Sky Access Line) -> [Nippori Station] –(JR Yamanote Line) -> [Ikebukuro]
For both cases, you have to take a train from Ikebukuro to Wako.
I recommend “Tobu Tojo line” from Ikebukuro to Wako. Choose “rapid express(快速急行)” or “express （急行）” or “semi-express(準急)“. It takes about 14 mins. https://www.tobu.co.jp/en/access/ikebukuro/
You can buy a traveling IC card for foreign travelers, so-called “welcome Suica” at Narita or Ikebukuro.
If you can come again, you should buy a normal IC card (SUICA or PASMO) because the welcome Suica will be expired in 28 days. Different railway companies provide SUICA and PASMO, but the usage is the same.
In addition, RIKEN cafeteria requests you to pay with SUICA/PASMO. Cash or credit cards are not accepted.
