Authagraph

Authagraph is an equal-area type world map projection that was invented by Japanese architect Hajime Narukawa (鳴川肇) in 1999.While conceptually in the category of an equal-area projection, it would require further subdivision to qualify as an actual equal-area map. In 2011 the Authagraph mapping projection was selected by the Japanese National Museum of Emerging Science and innovation (Miraikan) as its official mapping tool. As of 2015 it is used in official Japanese high school text books.
