Professional History & Key Achievements
1. Physics
1985: Systematized the "Soshiron" (Elemental Theory), a theoretical framework arguing that physics must objectify "actual existence" by transcending the conventional constraints of observability, reproducibility, and mathematical understanding.
Published a series on the fundamentals of "Soshiron" in the Japanese science magazine OMNI (published by Obunsha).
Was invited to be a founding member of the "Plasma Society" (Purazuma Gakkai), hosted by Professor Otsuki of Waseda University.
His work was highly regarded, presented by Dr. Hideo Itokawa alongside the papers of Nobel laureate Dr. Yoichiro Nambu. (Reference 1)
2. Superconductivity
1988: Based on insights from "Soshiron," he pioneered an analysis showing that the cause of high-temperature superconductivity lies in the layered structure of ceramics. This led to the development of a "conductive material with a conduction layer."
He filed a patent for this "conductive material." Although its effectiveness was verified by the major manufacturer Furukawa Electric Co., Ltd. (substantiating "Soshiron"), the patent was not granted. The patent examiner at the time could not comprehend the concept of the "atomic scale," as nanotechnology was not yet a recognized field.
("Soshiron" is considered to have been proven, as this material was demonstrated to "dramatically increase electrical current flow.")
3. Navigation Systems
Shifting his focus from natural sciences to information science, he established foundational technologies for navigation systems that would become Japanese Industrial Standards (JIS).
1989: Developed his first navigation system (patented in 19 countries). It received the highest evaluation from the Sanwa Venture Development Fund, earning an incentive grant of JPY 10 million.
His "Driving Line Method" was adopted as a Japanese Industrial Standard (JIS) and now serves as the fundamental system for current car navigation systems in Japan and internationally. (Reference 2)
1994: Developed Navigation System 2 (patented in 14 countries). The system's "Possible Area Method" was adopted by several companies, including Toyota and Panasonic. He won the Grand Prix in the 1st Recruit "Entre" Contest (Prize: JPY 3 million). (Reference 3)
1998: Developed Navigation 3 (patented in 14 countries), an integrated system including collision avoidance for air and sea routes.
2010: Developed Navigation System 4 (patented in 9 countries), the world's first system capable of targeting "moving objects."
4. Seismic Isolation (Menshin) Area Method
1995: Developed and patented a ground reinforcement method. It was adopted as a fundamental construction method by major general contractors like Kajima Corporation and Obayashi Corporation. It has been implemented in major projects including Tokyo Station, Mejiro Garden Hills, and the Sagamihara municipal housing complex.
5. Aluminum Die Casting
2018: Developed and patented an aluminum die-casting apparatus. This serves as a foundational patent for "Giga Casting," a critical technology for the EV industry. (A second patent application is planned to secure international patents).
6. Metaverse
He is evolving Virtual Reality (VR) and Augmented Reality (AR) into a concept he terms "Integrated Reality," for which a patent has been filed. (The application is pending coordination for an international PCT filing).
7. Relation Authentication System
2024: Developed an innovative authentication system and filed for a patent. This was created after discovering "fundamental" flaws in conventional authentication methods like passwords and passkeys. (Reference 4)
8. Relation Authentication Device and System
January 7, 2025: An international patent application was filed for this device and system under the Patent Cooperation Treaty (PCT), and the date of receipt was confirmed.
