Kikujiro (1999)

Brash, loudmouthed and opportunistic, Kikujiro hardly seems the ideal companion for little Masao who is determined to travel long distances to see the mother he has never met. Their excursion to the cycle races is the first of a series of adventures for the unlikely pair which soon turns out to be a whimsical journey of laughter and tears with a wide array of surprises and odd ball characters to meet along the way.
