After arriving at Narita airport you have several choices to get into the city:

Narita Express Run by JR (accepts JR Rail Pass) and has trains to Tokyo, Shinjuku and Ikebukuro. I prefer the Narita express because it is fast and convenient (especially if you can get one that goes directly to Ikebukuro). It is a bit more expensive than other options. If RIKEN is reimbursing you, you will have to pay about 1000 yen of your own money to make up the difference. Tickets are available at the counters right after you exit baggage claim, or on the floor below before you enter the ticket gates to the train. Try to get one that stops at Ikebukuro. If there are no convenient times, you can either take it to Shinjuku and change to the Yamanote line to get to Ikebukuro, or try one of the options below. Remember to keep your ticket after boarding since you will need it to exit at Ikebukuro.

Keisei Skyliner Trains to Nippori and Ueno where you will have to switch to the JR Yamanote Line to get to Ikebukuro. See here for more details.

Limousine Bus Offers direct buses to Wakoshi as well as major hotels in Tokyo including the Metropolitan Hotel in Ikebukuro. See here for more details. If you arrive late at night, this may be your only option. Can be slow due to traffic.

Here is a map that shows the possible connections. Ikebukuro is the closest station to switch to the Tobu-tojo or Yurakucho subway lines to get to Wakoshi where RIKEN is located:

To get to Wakoshi, you can take the Tobu-tojo line from Ikebukuro (Runs frequent express and semi-express trains that make only one stop at Narimasu before arriving in Wakoshi – taking 14 minutes) or the Yurakucho or Fukutoshin subway line.

If you know the time of your arrival, you can get exact scheduling information from hyperdia.com. As your start point, put in “Narita airport” and as your destination, put in Wakoshi. Hyperdia is a very useful site for planning any subway or train travel within Japan.

It is a 15-20 minute walk from the South exit of the Wakoshi train station to the RIKEN campus. Make sure to check in at the guard station at the entrance of the RIKEN campus. See here for more information on walking to RIKEN from wakoshi station and for a map of campus.
