This book is not a fiction.It is a story based on solid reality.
Hirosato Tanaka, author of this book, is not a penname but the real name.
I emphasize it because nobody with good sense would ever publish a book like this one under their real name; that would be a foolish act.
My readers might not understand what I mean yet, but I hope that they will be invited to some kind of beneficial understanding, while reading my book.
