Kumamoto Castle is Kumamoto’s most famous tourist spot. Did you know there is sightseeing bus dedicated to making travel around the castle convenient?
The name of that bus is the Shiromegurin Kumamoto Castle Sightseeing Bus. The bus departs from Kumamoto Station, makes a loop around various interesting spots around the castle, then goes back to Kumamoto Station.
The bus runs from Kumamoto Station and stops at different areas around the castle, like the Kotsu Center Bus Terminal, Johsaien, and Kumamoto Castle Ninomaru Parking, then makes stops in the downtown area, like at Kumamoto Hotel Castle and City Hall, then returns back to Johsaien and the Bus Terminal and then Kumamoto Station.
Each loop takes about 65 minutes, and the bus runs every 20 to 30 minutes everyday from 9AM to 5PM, with 38 loops each day.
Departs from Kumamoto Station Bus Platform #1
Leave the station from the Shirakawa (East) Exit and head left to the Shiromegurin bus stop in front of the One Station Hotel Kumamoto.
And off we go!
Most of the Shiromegurin seats are for single passengers. Right after departing, the bus travels through the historical castle town area of Shinmachi where you can enjoy the sights from the bus windows.
The atmosphere of the Shinmachi area is that of old-school, retro Japan.

Along the Ninomaru tour route, you’ll soon come across the Inui Turret, which just barely avoided complete collapse by miraculously being held up by a single column of the stone foundation that stood strong. The Iidamaru Turret was also propped up by a single column of stone immediately after the earthquakes but has since been disassembled for reconstruction.
Information panels are set up along the Kumamoto Castle Reconstruction Tour Route with more detailed information.
As of April 1, 2026, it is being demolished for restoration work.
