First it was the wakaba mark (also called shoshinsha mark), the green and yellow symbol that new drivers in Japan are required to display on their vehicles for one year. Wakaba marks gained popularity in the US when JDM scenesters began to plaster their cars with them in ironic fashion. Of course since we’re dealing with nostalgics, we opted for the kareha mark (also called fukushi mark), the counterpart for elderly drivers, for our logo and car. In case you hadn’t guessed, the color and shape of the marks represent a spring leaf and autumn leaf.
The four-leaf clover, so frequently seen on St. Paddy’s day, is part of a lesser known yotsuba (or shintai shougai) mark for handicapped drivers. It’s only been around since 2001 and it’s optional. Yeah, it’s not green, but hey, it’s hard to find the luck o’ the Irish in Japan.
