Last month a Tokyo art exhibition by XYZ Collective presented miniature versions of large exhibits the artists would like to build. They used Sylvanian Families buildings as the mini galleries to hold their work. You can view the exhibits here: Sylvanian Families Biennale 2017 (before you click: some exhibits have adult themes.)
The exhibits aren’t toy themed, which might limit our SF-fan interest in the individual mini-gallery contents, however we can definitely understand how Sylvanian Families buildings are so widely available in Japan that an exhibition would select them for a uniform visual impact in a gallery.
As an aside, I’m tempted to set up our basement with white-painted cardboard boxes and my SF buildings as a personal art gallery 😉
