And what does Kozu’s family have to say about his unusual passion? The father of two grown-up sons and five grandchildren said: “My wife was never particularly interested in my travels, but she was always very understanding.” She presumably had to be. Kozu’s love of Mercedes-Benz is so huge that he learned German on his own initiative, and also took an interest in German classical music: he is a fan of Brahms and Beethoven. “I love the Berlin Philharmonic Orchestra, especially when they were conducted by Furtwängler and Karajan”, he said enthusiastically.
Now 81 years of age, Kozu, who has a doctorate in aircraft engines and worked for many years as an engineer developing jet engines, also collects fountain pens from Germany. Yet Masao Kozu does not own a computer and does not want to buy one. What should he do with one?
