My Life As A Writer 2 (Souseki Natume) And other income is from my writings. I wrote fifteen or sixteen books and get the royalty on the books. You would want to ask me what rate I get the royalty on the books, my rate seems to be a little more high than other authors. Though publishers may be embarrassed, if I refer to this. My book that sold the most is 「I am a cat」 . The normal size and reduced version of this book in total went through thirty five editions. The number of copies is two thousands copies in first version and one thousand after that. However the book which went through thirty five editions was only first volume of this book, middle and last volume were less. My royalty income doesn't amount to much.
