Authored Books

I have published four complete books to date, one in English and three in Japanese, which are shown below together with their respective reviews. I have also made significant contributions to two major essay compilations on the future of Japan. In addition to these six books, I am currently writing two more manuscripts which should be published in the near future.

Also, as people in the information security field have inquired about my technology patents, I have included a list of registrations and applications at the bottom of the page for reference.
