Book Two of 1Q84 ends with Aomame standing on the Metropolitan Expressway with a gun between her lips. She has come tantalisingly close to meeting her beloved Tengo only to have him slip away at the last minute. The followers of the cult leader she assassinated are determined to track her down and she has been living in hiding, completely isolated from the world. However, Tengo has also resolved to find Aomame. As the two of them uncover more and more about the strange world of 1Q84, and the mysterious Little People, their longing for one another grows. Can they find each other before they themselves are found?

Murakami was born in Japan during the post–World War II baby boom.Although born in Kyoto, he spent his youth in Shukugawa (Nishinomiya), Ashiya and Kobe.His father was the son of a Buddhist priest,and his mother the daughter of an Osaka merchant.Both taught Japanese literature.

Since childhood, Murakami has been heavily influenced by Western culture, particularly Western music and literature. He grew up reading a range of works by American writers, such as Kurt Vonnegut and Richard Brautigan, and he is often distinguished from other Japanese writers by his Western influences.

Murakami studied drama at Waseda University in Tokyo, where he met his wife, Yoko. His first job was at a record store, which is where one of his main characters, Toru Watanabe in Norwegian Wood, works. Shortly before finishing his studies, Murakami opened the coffeehouse (jazz bar, in the evening) "Peter Cat" in Kokubunji, Tokyo with his wife.They ran the bar from 1974 until 1981.

Many of his novels have themes and titles that invoke classical music, such as the three books making up The Wind-Up Bird Chronicle: The Thieving Magpie (after Rossini's opera overture), Bird as Prophet (after a piano piece by Robert Schumann usually known in English as The Prophet Bird), and The Bird-Catcher (a character in Mozart's opera The Magic Flute). Some of his novels take their titles from songs: Dance, Dance, Dance (after The Dells' song, although it is widely thought it was titled after the Beach Boys tune), Norwegian Wood (after The Beatles' song) and South of the Border, West of the Sun (the first part being the title of a song by Nat King Cole).

Murakami is a keen marathon runner and triathlete, although he did not start running until he was 33 years old. On June 23, 1996, he completed his first ultramarathon, a 100-kilometer race around Lake Saroma in Hokkaido, Japan. He discusses his relationship with running in his 2008 work What I Talk About When I Talk About Running.
