Ten years have already passed since Juraisin won the Good Design Award in 1996 from the Japanese Ministry of International Trade and Industry (now the Ministry of Economy, Trade and Industry, or METI). Since then, our operation area has expanded to areas in Japan such as Tokyo, Saitama, Gunma and Niigata. We have received requests from major general construction companies, architectural offices, and government agencies. They have selected and installed the Juraisin Lightning Protection System or modified their systems to include Juraisin equipment. Featured by the Media We have also been introduced as “The New Lightning Rod” by various sources such as newspapers, electric industry magazines, NHK, BS-1 and internet publications. As a result, we are receiving requests for information everyday from all over Japan and countries such as Taiwan, South Korea and France. In 1999, we acquired a patent from the birthplace of the lightning rod, North America. Since then, we have also received requests for information from the US and Canada. Winner of the Good Design Award The Juraisin lightning rod is our G-mark (Good Design Award winner). We received high marks in the criteria for selection by the Japan Industrial Design Promotion Organization (JIDPO) of METI. The Juraisin lightning rod was proven in five points: appearance, function, quality, safety and environmental and economical efficiency. Moreover, we believe when used with our company’s development product, the Juraisin Lightning Protection System (discharge electrode, attached needle, ground construction) reliability increases providing, “lightning protection equipment that provides safety and peace of mind.” Outstanding Test Results for Juraisin In 2000, Yoichi Nagae (CEO of Rokko Electric Company, 5-26-30 Shiba, Minato-ku Tokyo) took a deep interest in our company’s Juraisin air terminal. He requested an appraisal of protective efficiency of Juraisin by the Shibaura Institute of Technology, Department of Advanced Engineering’s Energy and Environmental Research Center. In June 2000, Professor Katsuo Okumura, President of the Energy and Environmental Research Center began Appraisal of Protective Efficiency utilizing super capacity test equipment. In June 2001, the results of the Lightning Protection Effectiveness Comparison Test for Juraisin was published in the July edition of electric industrial magazine Ohm. Professor Okumura appraised the test results stating, “I believe that I could provide valid appraisal results.” What is a Ministry of Construction Type LR-1 Lightning Rod? Among lightning rods currently used in Japan, there is a type called Ministry of Construction Type LR-1. We believed that special technology and test data must exist for this lightning rod. Upon visiting the Ministry of Construction to find out more, we discovered that without a single reason, a Ministry of Construction Type LR-1 had been stipulated as copper of a thickness of 12 mm or more, length of 440 mm or more, with chrome plating. Consequently, we received an answer that our company’s Juraisin air terminal fit the JIS requirements of a Ministry of Construction Type LR-1. In reason, we were worthy of this standard even though our air terminal included modifications and improvements over other lightning rods of this standard. Lightning Rods Used Today The American scientist Benjamin Franklin invented the currently used lightning rod about 250 years ago, after he declared lightning an electrical phenomenon. The first lightning rod in Japan is said to have been installed in 1875 in Kanazawa City. The prototype of the lightning rod he created is still in use without any improvements and is often referred to as the “Franklin Rod.” In sharp contrast, the Juraisin air terminal includes improvements and modifications. Reasonable Costs Our estimated unit costs are the same as conventional lightning rod estimated costs. We have established a nationwide operation system that begins with the design and broadly covers operations to the final construction of the lightning protection system. We believe that by expanding our business, we can decrease lightning related accidents. Designs and Estimates We hope to continue working to prevent lightning related accidents in the future. In addition, we will be responsible for the design and estimate. So please feel free to contact us. We always look forward to hearing from you! We look forward to helping you with your lightning protection needs.
