What is "hokusai"

was a Japanese artist, ukiyo-e painter and printmaker of the Edo period. He was influenced by such painters as Sesshu, and other styles of Chinese painting. Born in Edo (now Tokyo), Hokusai is best known as author of the woodblock print series which includes the internationally recognized print, The Great Wave off Kanagawa, created during the 1820s.

Hokusai created the "Thirty-Six Views" both as a response to a domestic travel boom and as part of a personal obsession with Mount Fuji. It was this series, specifically The Great Wave print and Fine Wind, Clear Morning, that secured Hokusai’s fame both in Japan and overseas. As historian Richard Lane concludes, "Indeed, if there is one work that made Hokusai's name, both in Japan and abroad, it must be this monumental print-series...". While Hokusai's work prior to this series is certainly important, it was not until this series that he gained broad recognition.

Hokusai is a rayed impact crater on Mercury, which was discovered in 1991 by ground-based radar observations conducted at Goldstone Observatory. The crater was initially known as feature B. Its appearance was so dissimilar to other impact craters that it was once thought to be a shield volcano. However improved radar images by the Arecibo Observatory obtained later in 2000–2005 clearly showed that feature B is an impact crater with an extensive ray system. The bright appearance of rays in the radio images indicates that the crater is geologically young; fresh impact ejecta has a rough surface, which leads to strong scattering of radio waves.

Hokusai is named after Katsushika Hokusai (1760–1849), a Japanese artist and printmaker of the Edo period. The name Hokusai was suggested by radar astronomer John K. Harmon. The crater has a diameter of about 100 km; the rays extend for thousands kilometers, covering much of the northern hemisphere.
