Girl playing with kite, featured in the final scenes of the film is Takeshi Kitano's real-life daughter, Shoko Kitano.
The paintings that appear throughout the movie were painted by Takeshi Kitano himself after his near-fatal motorcycle accident in August 1994.
The Japanese title translates into 'Fireworks", but if you look further into the basis of the Japanese character for 'fireworks', you will see that it is composed of two smaller words - 'fire' and 'flower'. And like the linguistic basis of the title, the story and style of "Hana-Bi" is the synthesis of two opposing images, one being an agent of destruction, and the other a symbol of birth and renewal.
