Arashi no Yoru ni

Arashi no Yoru ni (あらしのよるに, lit. One Stormy Night) is the first in a series of children's books authored by Yūichi Kimura and illustrated by Hiroshi Abe. In 1995, the book won the 26th Kōdansha Literature Culture Award and the 42nd Sankei Children's Literature Culture Award.

When Arashi no Yoru ni was published in 1994, Kimura had no plans to continue the story as a series, but due to the popularity of the story and receiving considerable encouragement, he continued the story through five more books, ending with Fubuki no Ashita (ふぶきのあした, After the Snowstorm) in 2002. As the series became more popular, a compilation called Shiroi Yami no Hate de (しろいやみのはてで, At the End of White Darkness) was released in 2004 and a movie adaptation was produced. Soon after, Kimura wrote the seventh and last book, Mangetsu no Yoru ni (まんげつのよるに, One Full Moon Night).

Arashi no Yoru ni was published in Japanese textbooks by Mitsumura Tosho Publishing. In 2005, Gisaburō Sugii directed an animated film adaptation covering all seven books in the series. A CG-animated anime television series by Sparky Animation, Arashi no Yoru ni: Himitsu no Tomodachi (あらしのよるに ひみつのともだち, One Stormy Night: Secret Friends), began airing in Japan from April 4, 2012 to September 26, 2012.
