Real life Mario Kart racing is now available around Akihabara. Drivers are able to discuss their choice of character with organizers who then try and allocate everyone someone they like. Training is given, although since they are driving on the road a proper driving license is required. The racing itself lasts over two hours though racers can always pick up a drive-through if they find themselves flagging.
Items, such as bananas and shells are provided although the precise details of their use remains a mystery. Racers go from Akihabara to Shinjuku before finishing in Shibuya. If you manage to book a place at this event expect a lot of interest from tourists.
