The {{nihongo|'''Nagasaki Main Line'''|長崎本線|Nagasaki-honsen}}, or simply known as the '''Nagasaki Line''', is a railway line owned by the [[Kyushu Railway Company]] (JR Kyushu) connecting [[Tosu Station]] in [[Saga Prefecture]] to [[Nagasaki Station (Nagasaki)|Nagasaki Station]] in [[Nagasaki Prefecture]], Japan. There is a separate branch of this line from [[Kikitsu Station]] to [[Urakami Station]] by way of [[Nagayo Station]] and the Nagasaki Tunnel, avoiding a long detour.<ref>{{Cite web|title=TrainReview's Guide to Limited Express Kamome Trains|url=https://trainreview.com/train/ltd-exp-kamome|archive-url=https://web.archive.org/web/20200916001510/https://trainreview.com/train/ltd-exp-kamome|url-status=usurped|archive-date=September 16, 2020}}</ref>
