Winter Days is a 2003 animated film, directed by Kihachirō Kawamoto. It is based on one of the renku (collaborative linked poems) in the 1684 collection of the same name by the 17th-century Japanese poet Bashō. The creation of the film followed the traditional collaborative nature of the source material – the visuals for each of the 36 stanzas were independently created by 35 different animators. As well as many Japanese animators, Kawamoto assembled leading names of animation from across the world. Each animator was asked to contribute at least 30 seconds to illustrate their stanza, and most of the sequences are under a minute (Yuriy Norshteyn's, though, is nearly two minutes long).

“连句”是一种日本特有的文学形式，有些类似中国的对联，是由复数的歌人合作完成，前一人吟出称为“发句”的上句，后一人以意思相关的“举句”相对。本作将日本著名的连句作品松尾芭蕉七部集《冬之日》动画化，由川本喜八郎任监督，邀请了久里洋二、高畑勲、山村浩二以及其他日本及国外著名的35位动画家共同参与制作，采用了水彩、油画、水墨画、人形剧、ＣＧ绘图等多种表现形式，收录了包括川本喜八郎2部作品在内的全部35组36篇作品。这个套装除1张本编DVD外，还收录了8张纪录35未动画家取材的资料编DVD，极富收藏价值。仅包括本编的普通版DVD也将同时发售。
