One of the two Japanese pottery tea bowls designated as national treasures. This is the work of Koetsu Honami who was active from Momoyama period to Edo period. It was named meaning the one and only chawan formed by associating snow-capped Mount Fuji. On the other hand, it is also said that ash happened to get sprinkled on the glaze and the bottom half of the chawan turned black due to carbonization by chance. It is currently housed at Sanritsu Hattori Museum.
