A complete set of twelve woodcuts done by Yamanda Kotaro showing paintings of the famous artist Nagasawa Rosetsu (1755-1799)
They are together in a blockbook called 'Rosetsu gafu' and published by Aoki Tsunesaburo, in 1893.

The woodcuts bear the signature: 'Rosetsu sha' and his 'stamp'.

Nagasawa Rosetsu (長沢芦雪?, 1754–1799) was an 18th-century (Edo period) Japanese painter of the Maruyama School, known for his versatile style. He was born to the family of a low-ranking samurai. He studied with Maruyama Ōkyo in Kyoto

There are conflicting versions of Rosetu's family origins, but the most credible appears to be that he was born to the family of a low-ranking samurai named Uesugi Hikouemon in the area of modern Kyoto Prefecture. Upon establishing himself as an artist, he changed his name from Uesugi to Nagasawa. He moved to Kyoto in 1781, where he became a student of Maruyama Ōkyo.
Rosetsu's early period works are in the style of Maruyama Ōkyo, although critics agree that the pupil's skill quickly surpassed his master's. Finally, they had a falling out and Rosetsu left the school. After the break, he worked under the patronage of the feudal lord of Yodo and accepted commissions at several temples.
Rosetsu's paintings fall into two very clearly defined categories, with no halfway stage in between. On the one hand, there are those of studied finish, and on the other, those--the great majority--that were clearly the work of a very few minutes of intense activity, whatever the preliminary thought and calculation. We are inclined to think of the first type as early and even untypical, but in fact Rosetsu seems to have executed carefully finished paintings at all stages of his career.
He incorporated aspects of Western realism into Japanese themes. In his work, which is reminiscent of earlier Zen painting, while the moon is left white, the night sky, mountains, and pine trees are depicted with gradations of India ink.
