 The line’s symbol is a capital I on a solid golden-orange roundel; while all other lines use Parisine for their mark, the “I” of the Imazatosuji Line has serifs, similar to Verdana.As with the Nagahori Tsurumi-ryokuchi Line, the Imazatosuji Line utilizes linear motor-driven trains with a cross-section 20% smaller than that of conventional subway cars, outfitted for driver-only operation.The line runs north-south through the eastern part of Osaka city, underneath National Route 479 (Osaka Inner Loop Route), National Route 163, National Route 1 (Keihan National Highway), and Imazatosuji, intersecting subway lines radiating out from the city center, as well as the Keihan Main Line and the Katamachi Line (Gakkentoshi Line).
