Kikujiro (Japanese: 菊次郎の夏, Hepburn: Kikujirō no Natsu; lit. Kikujirō's Summer) is a 1999 Japanese road drama film written, directed and co-edited by Takeshi Kitano, who also stars in the film with Yusuke Sekiguchi. Its score was composed by Joe Hisaishi. The film was entered into the 1999 Cannes Film Festival.

Kikujiro tells the story of a young boy searching for his mother during his summer vacation. The film is mostly divided into smaller chapters, listed as entries in the boy's summer vacation diary. Kitano's inspiration for the character (not the film) was his own father, Kikujiro Kitano, a gambler who struggled to feed his family and pay the rent.

Similar to his earlier works Getting Any? and A Scene at the Sea, Kitano references the yakuza only tangentially in Kikujiro, a departure from his work in crime dramas such as Sonatine and Hana-bi. Aimed at the whole family, the film was allegedly inspired by The Wizard of Oz with the basic premise being a road trip. Kitano's familiar elements and locales are present: drawings, vignettes, the seaside, and angels. Although the plot is composed largely of sad events, the film often has a light-hearted atmosphere, achieved mostly through Kitano's character and his somewhat bizarre encounters.

Masao, a young boy, who lives alone with his grandmother in an old Shitamachi area of Tokyo, receives a package, and in looking for a seal finds a photo of his long lost mother. He finds her address in Toyohashi, several hundred miles to the west. Leaving home to see his mother, he meets his grandmother's neighbors, Kikujiro and his wife. Kikujiro's wife forces the sleazy, lazy and brash Kikujiro to accompany Masao on a journey to see his mother, telling Masao's grandmother that they are going to the beach.

At the start of their journey, Kikujiro is not serious about reaching Toyohashi. Instead he gets absorbed in track cycling races and gambles away all their money. Later, left outside a yakitori restaurant, Masao encounters a child molester. After a narrow escape, Kikujiro promises to keep to the journey and take Masao to his mother.

When the taxi Kikujiro steals breaks down, they are forced to hitchhike to Toyohashi, meeting various people along the way. They get lifts from a juggler and her boyfriend on a date, and a travelling poet who delivers them to Toyohashi. When they finally reach the address of Masao's mother, Kikujiro finds her living as a housewife with another man and their daughter, leaving Masao to tears. Kikujiro tries to console him by explaining that his mother had probably moved away. He tries to comfort Masao with a small blue bell shaped like an angel bullied from two bikers whom he happens to come across.

Masao is so disappointed that Kikujiro cannot help but try to brighten up their return trip to Tokyo. He tells him an angel will come at the sound of the bell.

They visit a summer matsuri held in a local Shinto shrine. While Kikujiro gets into trouble with some yakuza over a fixed shooting game, Masao dreams of dancing tengu.
