I want my readers to laugh sometimes. Many readers in Japan read my books on the train while commuting. The average salaryman spends two hours a day commuting and he spends those hours reading. That’s why my big books are printed in two volumes: They would be too heavy in one. Some people write me letters, complaining that they laugh when they read my books on the train! It’s very embarrassing for them. Those are the letters I like most. I know they are laughing, reading my books; that’s good. I like to make people laugh every ten pages.
