[2] In Osaka, 1956, Shigeo, a child living with his parents Shinpei and Sadako in a small diner near the river mouth, meets a boy named Kichi.

Rumors circulate that their mother entertains customers on the boat for a living, but Shigeo doesn't fully comprehend.

As Oguri recounted during lectures and other events, the president of a small to medium-sized company, originally a film enthusiast, had another project in the works that had to be abandoned due to unforeseen circumstances.

Despite Oguri's inability to find a suitable filming location in Osaka, he scoured Hiroshima and Tokyo without success.

Due to Mariko Kaga's prior commitments, a boat was transported to Toho Studios, where all scenes involving her were shot within a six-hour timeframe.

Oguri turned to Nobuhiko Obayashi, a close friend from his early filmmaking days, who introduced the film to the Sogetsu Hall.

Shigeru Okada, President of Toei, was deeply moved upon viewing the preview, describing it as an excellent film.
