I'll be in Tokyo in late Feb. I'll now be staying in the Nippori area so N'EX + Suica is no longer a suitable option out of Narita, using Keisei instead.

A couple of doubts:

Is there a Keisei equivalent to Suica + N'EX?

At Narita, can I buy a PASMO along with a the Keisei ticket to Nippori?

Many thanks.
