ABOUT
About Mashiki Town
Mashiki was formed in 1954 by merging one town and four villages, including Kiyama Town. Home to Aso Kumamoto Airport, it is a transportation hub next to eastern Kumamoto City. After the former office building became unusable in the 2016 Kumamoto Earthquake, the town office began operating in a new building in Oaza Miyazono in 2023.
