The Amagi Line (甘木線, Amagi-sen) is a Japanese railway line connecting Kiyama Station (on the Kagoshima Main Line), Kiyama and Amagi Station, Asakura. This is the only railway operated by the third-sector railway company Amagi Railway (甘木鉄道, Amagi Tetsudō). The company, and sometimes the line, are also called Amatetsu (甘鉄). The line functions as a commuter rail line for Fukuoka. The Kirin Brewery Co. is a shareholder of the company as a result of the former approximately 1 km siding from Tachiarai that serviced its nearby brewery.[citation needed]
On April 5, 1985, it was agreed that the line would be transferred to a newly created third sector railway company. Amagi Railway was thus created and inherited the former JNR line on April 1, 1986.[1]
Heavy rainfall damaged a bridge between Oitai and Matsuzaki in 2006 and buses provided the link between those two station for six months until the bridge was repaired.[citation needed]
