Fuji TV's documentary series, "The Non-Fiction," celebrates its 20th anniversary this week with a special program, "Watashi wa Dare?" ("Who Am I?"; Sun., 2 p.m.).

John Ho, a successful businessman throughout Southeast Asia and based in Singapore, wrote a letter some time back to the producers of the program, requesting their help in finding out about his father.

Born in 1945 in Malaysia right after the end of World War II, Ho was raised by his single mother who always told him his father was a Chinese expatriate who had left before he was born. But just before she died 30 years ago, she confessed that actually Ho's father was a Japanese soldier who was ordered to return to Japan just before the end of the war, when she was pregnant with John. It was the last time she saw his father.
