It¡¯s a cold, wet morning and frigid air is seeping through the open doors of a college gymnasium in Tokyo. But that doesn¡¯t seem to worry Soichiro Kakimoto and 30 other young businessmen as they gear up for their weekend routine: cheerleading.

¡°Smile when times are tough!¡± shouts a tall man with an eager smile. The others ¡ª all dressed in dark suits and ties ¡ª pump their fists and jam to the upbeat music that fills the space.

Their chants echo through the gymnasium.
