to Shibuya station.
There are at least 3 ways.
<ul>
<li><a href="http://www.jreast.co.jp/e/nex/index.html">
Narita express.</a>
This can be the easiest although not the cheapest.
You can buy a ticket at the Narita airport
station valid up to Shibuya.
You find a ticket counter immediately after you
leave the custom area.
There are also vending machines near the entrance to
the station. 
They accept both bills and coins (Japanese yen only)
and give you changes.
I suppose they accept credit cards but
I am not sure if they accept ones issued abroad.

the second stop is Komaba-Todai-mae

station. It costs 120 yen.
An express does NOT stop there.

It is convenient to buy a prepaid 
electric money
called Pasmo or Suica. 
By charging the money in advance,
you can use it to take any subway, metro, bus,
including the Inokashira line and the Yamanote line.
You can also use it to pay
at any convenience stores.
You can get back the deposit 500 yen when you finish using
and return the card.

if you know the way.
It is about 20 min.

the guard at the Main Gate.

You can enter the room after 3pm.
If you arrive earlier, you need to kill time
e.g at a cafe north of the math building.
