The thinnest paper in the world, tenjugo, comes from a single factory in Japan's Kochi prefecture.
Tenjugo was produced by hand for over 1,000 years, until the 20th century. It has been used for ceremonial purposes, including writing and artwork, and later as paper for typewriters, Oliver Whang at The New York Times reported. Now, the paper is made using machines, and is thinner than ever.
