The film is based on the life of Leonie Gilmour, the American wife of Japanese writer Yone Noguchi and mother of sculptor Isamu Noguchi and dancer Ailes Gilmour. Production started in April 2009.
Matsui is an independent filmmaker who previously directed the films Yukie (1998) and Ori ume (2002).

On Feb. 12, 2009, Production Weekly listed the film as a production of Hyde Park Entertainment to be produced by Ashok Armitraj and Patrick Aiello, with Emily Mortimer and Shidou Nakamura identified as cast members.  On April 27, 2009, Production Weekly reported that actresses Christina Hendricks and Mary Kay Place had joined the cast, which was said to be currently filming in New Orleans.
Production in the Santa Ynez Valley on May 11–14, 2009 was reported in The Santa Ynez Valley Journal. According to the story, a local ranch "was used as the setting for a small settlement just outside Pasadena in 1904, where settlers are trying to eke out an existence in the hard scrabble life of the time."  The article also noted the participation of local residents as extras, including seven-week-old Jordyn Oltman serving as "Baby Isamu photo double."
On July 30, Matsui returned to the United States and began postproduction work in Los Angeles. On September 1, 2009, she reported on her selection of Barbara Tulliver as editor, citing Tulliver's work on numerous films, and noting her extensive work for David Mamet. .
