Transportation within Kumamoto City and some of its neighboring towns is accomplished through a fairly extensive bus system and a simple two line tram system. City day passes are available that can be used on both the bus system and tram lines.
By bus
Buses run fairly regularly from stops through Kumamoto City. Kotsu Center, the main bus terminal, is located near the downtown area just nestled in the few blocks between Kumamoto castle and the nightlife districts and is easily reached by taking the tram to the Kotsu Center-mae stop.
By Tram
One tram line runs from Kumamoto Station and the other from Kami-Kumamoto Station. They meet near the downtown area and run east to Kengun Machi. One trip costs ¥150.
By bike
Kumamoto is a comfortable city to ride around. For reference, it takes about 30 minutes by get to Kumamoto Gakuen University from Kamikumamoto.
