I am a Japanese author who is focusing on cyber-security issues. I have published more than 20 books since 2011. Most of my books are cyber-mystery.
My theme is cyber-munitions companies and the manipulation of public opinion via social media recently.
I am also writing articles about the same fields for various magazines and web sites.
