The schedule of limousine bus "Rose Liner" operated by "Ibaraki Koutsuu" and "Chiba Koutsuu" is as follows

More information about Rose Liner http://www.ibako.co.jp/bus/hwbus/roseliner-e/roseliner-e.htm
One way fare is 3,000 Yen.(no discount for the return ticket). You must buy a bus ticket at the ground transportation counter beforehand. It is necessary to check the bus stop number (maybe more than 30 bus stops in total), because even toward Ibaraki prefecture, there are several different bus routs. You can deposit one suitcase in the trunk room. They will give you claim tag, which is necessary when you get off the bus. The bus may skip any bus stop, if there is no request to stop. You should get off at JR Tokai station (the find destination). Rose Liner stops at the east entrance of JR Tokai station.

There are two routes to get to Mito, Hitachinaka and Tokai area by train. In the underground level of Narita International Airport there are railroad stations of different railroad company (JR and Keisei) adjoining each other. These services connect Narita airport to Tokyo area. Therefore you must change train at least once in the Tokyo area. The fare of Keisei is slightly cheaper. However, for the first visitor to Japan, I recommend you to take JR because you must use JR between Tokyo station and Mito station. (JR denotes Japan Railroad company.) If you are already familiar with the area around Keisei-Ueno station and JR Ueno station. You change train from Keisei to JR in the Ueno area.

Buying ticket
You must buy passenger ticket from Narita Airport station to Tokai station. This ticket allows you to take local train. You must keep this ticket all the way to Tokai. If you use express trains, you must buy express tickets for each train in addition to the passenger ticket. You may be asked to show these tickets any time by JR staff.

• From Narita Airport Station to Tokyo Station
  You have two choice. One is to use rapid train "Airport Narita". It takes one hour and half to go to Tokyo station. The train service is every one hour during the day time. You can use this train without express ticket.
  The other is to use Narita Express (NEX). It takes one hour to go to Tokyo. The train service is every half hour during the day time. Since all seats are reserved in NEX, you must buy express ticket with seat reservation.
  Both trains stops at the underground level of Tokyo station.
  
• From Tokyo Station to Ueno Station
  Take JR Yamanote line (silver colored train with green stripe) north bound at the platform number 4. This is a local train. It takes about 10 minutes from Tokyo Station to Ueno Station.
  
• From Ueno Station to Mito Station
  Use Express Super-Hitachi or Express Fresh-Hitachi of JR from Ueno station to Mito station through Joban line. The train service is every half hour during the day time. It takes about one hour and ten minutes (it depends on trains you take) to get to Mito Station. There are reserved seats and non reserved seats in this express train. Express ticket with or without seat reservation is necessary.
