TOKYO【日暮里駅】.Transfer From Keisei Nippori station To JR Nippori Station.

Many travelers feel quite confused about Transfer system for JR line from Keisei Skyliner at NIppori Station.
I think it is necessary to get PASMO or Suica card at Narita airport in advance.
PASMO is as same as Suica, the point of difference is the issued of Company.
travelers are wondering why this connection is directly platform of JR line? because of convenience of Commute for business person, not Travelers.
