The company name Keifuku (京福) was named after Kyoto (Kei: 京) Prefecture and Fukui (Fuku: 福) Prefecture, where the company once operated the railway business; however, there was no plan to build a railway connecting Kyoto and Fukui prefectures.
京福の社名は、鉄道事業を行っていた京都と福井の頭文字を採ったものだが、京都と福井を結ぶ鉄道計画があったわけではない。
