Googled pictures of the Japanese National baseball team, and then googled their wikipedia, noted that the english wikipedia article lists their names in western naming order (first first, family second). Matched some of the players names to the names on their jerseys in the photos.
They have names on their jerseys like "Nakano" (#7) and "Okamoto" (#25) and "Nakamura" (#27) - these are their family names.
