Refers to the work of a school of painters begun around 1600 by Sōtatsu and his contemporary Hon'Ami Koetsu, revised in the 18th century by Korin and again in the 19th century by Saki Hoitsu. The alternate name for the school, "Rimpa" is devised from the last syllable in Korin's name (rin) and the word school (ha). The style is characterized by an adherence to the classical Japanese sense of decorativeness, delicate coloring, and a keen observation of the natural world. Precious materials such as gold and silver along with colors were used on folding screens, fans, and other objects. Subject matter was taken from medieval literature as well as nature. Although the style did not last past the Edo period (1600-1868), it influenced 20th century Japanese painting.
