As of 2021, the Chikuho Main Line is the third shortest of all Japan Railways Group lines named Main (or trunk) Line (not counting the JR Shikoku main lines, which were stripped of their designation after JR Shikoku started operating). For comparison, the shortest is Hidaka Main Line (30.5 km), after the closure of 116.0 km due to storm damage in 2015.

The line is divided into three sections. Each section has an alias.
