The fare is 430 JPY between Tsukuba Center and KEK in all these lines. Just after getting on the bus from the middle door, you must take a white ticket with a printed number from an iron box at the door. This ticket prove where you get on the bus. When you get off the bus from the front door, you must drop the fare with this ticket into the box beside the driver. It may be rather difficult to find where you are getting off. There is an recorded announcement in Japanese for each bus stop. If you hear "KOH E-NE-RU-GUI", it is the bus stop at KEK. You must push one of buttons on the wall to notify the driver that you are going to get off. Although you cannot expect the bus driver speaks other languages than Japanese, it will be very useful to say "KOH E-NE-RU-GUI" showing this map to the driver when you get on the bus.
