JR Highway Bus is joining the operation of this bus service starting Dec 16, 2014. The frequency rises from 61 to 78/ day.
:-: JR Highway Bus is setting up a dedicated bus stop for this joint operation at Tokyo Station. One minute walk from Yaesu Exit, Tokyo Station. This will help easy connection to/from the Shinkansen Lines because the platform of the Shinkansen is just next to Yaesu Exit. Narita Express may have some disadvantage, for it uses the platform on the basement 5th floor and it' on the other, Marunouchi, side of the station.
