"This red-brick aqueduct was once part of eight over-head rivers in Kyotanabe. Now only three are left. They have been nicknamed ""Manbo"" although it is not clear why. This manbo has train lines running under its triple arches. The origin of word is unknown. Manbo over the railroad in the east of Tanabe Elementary School is called Mitsumanbo, because it has 3 tunnels."
