Mitsuhiro Fujiwara, Fujiwara Sangyo Co.
In the Footsteps of Invention
Founder of Fujiwara Sangyo (disaster prevention and water treatment facilities)
Born on November 12, 1942 in Showa 17 (A.D. 1942).
Born in Bizen City, Okayama Prefecture. His ancestor was Sueko Fujiwara, a wandering nobleman during the Onin War.
Studied at Okayama Prefectural Wake Kankaya High School, which has its roots in the Kankaya School established by the Okayama Domain.
July 1980: Established Fujiwara Sangyo Co. Ltd. and assumed the position of Representative Director.
Entered the water environment business with the idea that “Japan’s technology should be able to improve the water environment even more! Fujiwara entered the water environment business.
June 1982: Completed the Fujifloat automatic scum removal system. Subsequently, he developed a number of revolutionary devices, including a sludge scraper.
December 1992: Awarded the Invention Meritorious Service Award by the Governor of Osaka Prefecture. Received the Osaka Superior Invention Award.
January 1995: Hearing the news of people suffering from earthquakes and tsunamis, he entered the disaster prevention business, thinking, “With a little equipment and measures, more lives could be saved! So, we entered the disaster prevention business.
1995 Proposed a disaster relief set. Developed the “Safety Bed Frame”.
2003: Developed the Tuscal Tower for tsunami evacuation.
In response to the seriousness of global warming, we began research on the global environment, saying, “We must find a way to revitalize the Earth as soon as possible.
Nov. 2005: Discovered that seawater grows trees.
July 2009: Presented a paper at a symposium of the Shanghai Center, Kyoto University, on an artificial rain cloud generation system.
Currently, as the “Fujiwara Earth Defense Force”, we are constantly communicating our research and activities through various media.
April 2012 Opened Tohoku Sales Office in Sendai.
February, 2013: Visit from Canada to inspect the production line, monorail sludge scraper, and automatic scum removal system of Fujifloat.
October, 2014: Developed a shelter against mudslides.
October, 2014: Volcanic eruption protection shelter developed.
November 2014: Development of FM gas and magma removal method for volcanic eruptions
March, 2015 Development of the Kaiza Calendar from the uplift of the sea floor.
Footprint of Invention
Main pillar arrangement for the purpose of “drift avoidance” based on verification experiments conducted by the Disaster Prevention Research Institute of Kyoto University.
Placement of buffer piles to reduce the impact of drifting debris.
P-wave sensor system for unlocking doors, flashing patrol lights, and emergency broadcasting.
Additional functions such as emergency food storage boxes can be installed.
It was in the winter of 2015 when I first learned about the late Mitsuhiro Fujiwara.
At the time, I was researching various disaster countermeasure information, hoping to combat any kind of disaster. One day, I was surprised to learn that there was a person who had such a bold idea about volcanic eruption countermeasures, and it was Mr. Fujiwara, the inventor of the Fujiwara Volcano Gas Venting Method. This was the beginning of my admiration for him. Less than three years later, in the fall of 2018, I had my first meeting with him.
A seminar organized by an academic society was held at Kansai University, and I attended it.
It is still fresh in my memory that when I greeted him, I felt a strange sense of nostalgia for some reason.
It was similar to the inexplicable warmth that enveloped the disaster-stricken areas immediately after 3.11, where people were helping each other and caring for each other even if they were suffering. Mr. Fujiwara has always acted with the attitude of “I will put all my company’s profits into disaster prevention-related development! Mr. Fujiwara always acted with this attitude. In a world where self-interest tends to be the top priority due to the negative effects of excessive capitalism, his attitude of trying to save the lives of others alone taught us something that the Japanese people have lost.
It was also his long-cherished wish to bring to the world many of his inventions.
I would like to introduce some of them here again.
Finally, I would like to express my deepest gratitude to Dr. Hiroshi Asanuma of Chiba University for providing me with the opportunity to meet him, and to Mr. Hideshi Hayashi, who has been his greatest disciple and mentor.
