Strongly resembles Sadaharu Oh in the home run trot wearing the Giants #1 at Korakuen Stadium. Not sure what the date was, since he hit over 800 homers it might be tough to nail down which landmark this might be!
Korakuen Stadium was home to the Giants before the Tokyo Dome, this pic is from 1956 and shows the batters eye and centerfield stands with similar scoreboard config to what we see in your pic.
