Arts preview: Maywa Denki's 20th anniversary music art exhibition

For an art group that cites "nonsense" as its core philosophy, Maywa Denki's longevity defies common sense.

Founded by brothers Masamichi and Nobumichi Tosa in 1993 - 14 years after their father's eponymous manufacturing company went bankrupt - the quirky outfit is now celebrating its 20th anniversary with projects in Taiwan, Hong Kong and their native Japan.

"From day to day, I work hard to provide the customers with a dream of 'life with Maywa Denki'," says president Nobumichi Tosa, who has been the group's sole leader since Masamichi's retirement in 2001.

"Maywa Denki products probably won't go with the decor of your living room, but the incongruity will make you think about the meaning of normality, of common sense and of life," Tosa says, referring to the electronic and mechanical devices - designed by him and his team - that have long come to define the self-professed "company".
