She is passionate about helping others and always strives to find the truth.

The Kurogane Railway was formed by reorganizing cargo train lines that once ran through Kitakyushu’s steel industry and the Chikuho Coal Field areas.

The Rise of the Kurogane Railway

A Journey for a Nostalgic Sound

Mumumu is drawn to a nostalgic sound called “Kawahira-ta,” which means “river flat.”
