An impromptu painting done upon request at a meeting with a guest or patron. It is recorded that Kano Kagenobu 狩野景信(fl. ca. 1435) painted such a work in the presence of his patron, Shogun Ashikaga Yoshinori 足利義教 (1394-1441). Likewise, Kano Tan'yū 狩野探幽 (1602-1674) is reported to have painted a sekiga for his patron, Shogun Tokugawa Hidetada 徳川秀忠 (1579-1632). However, this term is more commonly associated with paintings produced during the mid-to-late Edo period by Southern school *nanga 南画 artists and Maruyama school *Maruyama-Shijō-ha 円山四条派 followers. Sekiga can be divided into three general types: paintings produced at farewell and drinking parties; those painted in the presence of important guests and patrons; and impromptu paintings sold in order to buy art materials. However, among his written works, the famous Edo period nanga painter and art critic Kuwayama Gyokushū 桑山玉洲 (1746-99) expressed disapproval of impromptu painting in general, saying that painting should be approached seriously and not in the context of party games and drinking. From this time on, sekiga declined in popularity.
