Muji makes houses! I love peeking inside the 2 story model house inside the huge Muji store in Yurakucho, Tokyo. I'm kind of dying to visit Muji Village outside Tokyo and tour a model condo. I could totally see us living in an open airy Muji house, but I'd need to add some colorful art to the walls to make it more me.
