Tokyo Giants Youth League.

A children’s film that teaches proper baseball posture and knowledge to kids, based on the premise that a weak youth baseball team, “Kodomo Giants,” receives coaching from players of the Yomiuri Giants (Yomiuri Kogyo Co., Ltd. / Tokyo Yomiuri Giants). It was released in July 1976, following “Tsutomu-kun from the Yamaguchi Family”, as a non-TV-affiliated short live-action film in the “Toei Manga Festival,” and became the only sports film of its kind in the series.
