The Karatsu Line (唐津線, Karatsu-sen) is a regional railway line in Saga Prefecture, Japan, owned and operated by Kyushu Railway Company (JR Kyushu). It connects Kubota in Saga City to Nishi-Karatsu in Karatsu City, both in Saga Prefecture, Japan.[1] The line was originally constructed to carry coal from the Karatsu coal fields to the Port of Karatsu for export and had many branch lines to coal mines which have since closed.[2][3]
