Filming of "Mr. Baseball" took place primarily in Nagoya, with limited filming in Tokyo, Florida, and New York. Doug Claybourne, one of the producers, began preparation for location filming in Japan in 1991. Most scenes were filmed in the city of Nagoya, including a number that were eventually cut from the film. Most prominent are the scenes filmed at Nagoya Stadium, the former home of the Chunichi Dragons in Otobashi, Nagoya. Thousands of local extras volunteered to sit in the stands during the filming of game situations, even braving a typhoon to cheer on the fictionalized Dragons during their climactic showdown with the Yomiuri Giants.
