The Aigi Tunnel (愛岐トンネル, Aigi Tonneru?) is a 73.28 metres (240.4 ft) long railway tunnel located between Zenjino Station and Nishi Kani Station on the Hiromi Line in Japan. It is called Aigi Tunnel as a portmanteau of "Aichi" and "Gifu" because the tunnel is on the border between Aichi (Ai-) Prefecture and Gifu (-gi) Prefecture. The nearest stations are Zenjino Station in Aichi Prefecture and Nishi Kani Station in Gifu Prefecture.
