Our philosophy
Showcasing the potential of developing countries
Motherhouse began in Japan with a simple belief: true beauty starts where things are made.
In 2006, founder Eriko Yamaguchi set out from Bangladesh to build a world-class brand that uplifts people and materials at their source. The idea was simple, to design with respect, create with care and connect people through products made to last.
