Tokyo buses are two different types of buses. If you hop on a "front-boarding" bus (type 1), you'll pay a flat fare as you step on. If you catch a "rear-boarding" bus (type 2), you enter from the rear, receive a ticket and pay once you reach your destination. The fare for your particular ticket will be posted on the electric signboard at the front. You'll insert your ticket and your money into the machine at the front of the bus. But, before reaching these worries, you'll have to figure out which bus to take. Finding a bus map may also prove challenging. Our ultimate suggestion: Don't take a bus unless a locale explicitly tells you to do so. Bus fares for adults start at 200 JPY
