This is an everyday working service, which is part of its appeal: you travel the way the region itself travels. It is a short hop between Kumamoto and Miyaji, so the interest is concentrated rather than spread out, there is little dead time either side of the best stretches. Passing Aso Station gives the journey its midpoint, and the character either side of it is noticeably different. With only a handful of calls, the journey holds its momentum from end to end.

The Kyushu Shinkansen runs the length of the island from Hakata in Fukuoka to Kagoshima-Chuo, calling at Kumamoto on the way. Mizuho services cover the whole line in about 1 hour 19 minutes, which is why the train has largely replaced flying between the two ends of Kyushu.
