Tezuka famously studied medicine during and after WW2. But the reason he gave up becoming a practicing doctor was because his adviser told him, “If you become a doctor, you will undoubtedly end up killing a patient. Please become a manga writer instead.” His advisor knew perfectly well that Tezuka drew manga during class.
Tezuka was the first manga writer in history to be on the Japanese government’s list of the top taxpayers in the country. This immediately made him a target of gossip magazines, but when a journalist visited him in Tokiwa-so, he was shocked by Tezuka’s frugal lifestyle and wrote a comical article about how the famous millionaire lived in a broken-down apartment building with a draft everywhere. Tezuka’s pride was hurt, so he gave his room to Fujiko Fujio and moved to a new, pristine apartment building. He brought in a stereo set, TV, and even a piano to his new room, which meant there was no space left to actually work, so he ended up drawing manga while lying on his stomach under the piano.
While Tezuka was engaged to Etsuko, his future wife, he was so busy that they could only go on a date three times a year. While on these dates, Tezuka spent most of the time taking naps.
Tezuka was busy all through his life, so in his 30-year-long marriage, it’s said that he only spent about a year and a half total with his wife. When an acquaintances jokingly asked him, “How did you have time to make three children?” Tezuka replied, "Oh, it only takes five minutes to make those."
Tezuka’s trade mark was his beret. When he was young, the beret was to hide his naturally curly hair. But then his hair started to fall out, and by the time he was in his forties, the beret was effectively a toupee.
Tezaka loved sweets, and suffered from severe cavities. By his fifties, he wore a full set of dentures. He often forgot where his put his false teeth, and his family as well as all his assistants had to search for them all through the Tezuka Productions offices.
One time, Tezuka was set to go on a company trip with all his assistants. But on the day of departure he lost his dentures, and started whining about how he wouldn’t go on the trip if he didn’t have his teeth.
One other time, Tezuka lost his dentures on the day that he was scheduled to make a TV appearance. All his assistants looked for them, going as far as to go through the trash, but they couldn’t find them. Tezuka appeared on TV wearing a mask and said he’d caught a cold.
Tezuka was famous for his long bathroom visits, and his record was two and a half hours. This was because he got his best ideas in the bathroom.
Back when the Tezuka Productions offices were located in Takadanobaba, Tezuka’s office was a forbidden room that no one but his wife was allowed to enter, not even editors or his assistants. One summer day, Tezuka asked for an assistant to come to his office door. Tezuka came out of the office wearing only a suteteko (long underpants), his upper body naked. He apologized, using one hand to give the manuscript to the assistant. The other hand was covering his nipples.
Ishizaka Kei, a manga writer who was originally employed by Tezuka Productions, has been in the forbidden room. She was shocked when she noticed a roach motel in the fridge.
