I believe the Dove emblem on the Keihan train had an influence of the founder of my favourite band.. "BAND-MAID"...The bands founder, Miku Kobato, has a pigeon persona and I'm sure I read while traveling on a Keihen train she saw the dove emblem and the dove persona sprang from there!... I have traveled to Japan (from UK) twice to see the band LIVE..Once in Tokyo, then in Yokohama.
