The service started in 2019.[3] The train is run by the Heisei Chikuhō Railway Company.[1] It was designed by Eiji Mitooka and is based on the concept of “relaxation, delicious food, and fun”.[1] The train is bright red on the outside with a wooden interior using Ōkawa "kumiko" (lattice) woodwork[4] and stained glass ceilings.[5] Food is served using local natural ingredients. The service is slow for sightseeing purposes and has 48 seats.[4]
The train passes through the former coal mining area of Chikuhō (now part of Iizuka, Kaho District).[6] The name "Coto Coto" sounds like the noise of the train. The service includes French cuisine produced by Takeshi Fukuyama, a chef from Fukuoka. The ingredients in the appetizers come from nine cities, towns, and villages on the route used by the train.
