The page for Gringo at TezukaOsamu@World claims that the protagonist was based on Nobuyuki Wakaoji, a Japanese businessman who was kidnapped in the Philippines in 1986 and released after four months of captivity. This event was a major piece of shocking news that shook Japan. Coincidentally, the day Tezuka died was also the day Nobuyuki Wakaoji died.
