The London-as-Tokyo Tour is an action by Momus and his Japanese girlfriend Hisae Mizutani in which they'll ply up and down the pedestrian walkways of the South Bank dressed as tour guides, speaking through loudhailers about the buildings and sights as if they were places in Tokyo. Momus gave his first 'Unreliable Tour' in 2006, when he was invited to participate in the Whitney Biennial in New York, circulating daily through the galleries giving invented (and often absurd) accounts of the art on show. During Hide and Seek, Momus and Mizutani will transform London into Tokyo - a city they both know well - using nothing more than language and the collective power of imagination.
