◎ Kaiyomaru UFO Incident (Dec. 18, 1984/Dec. 21, 1986) ◎
On both days of December 18, 1984, and on December 21, 1986, Fisheries Research Vessel (Fisheries Resources Survey and Marine Environment Survey) “Kaiyomaru” belonging to the Fisheries Agency, which is an external bureau of the Japanese Ministry of Agriculture, encountered UFOs twice in different sea areas while sailing. The Kaiyomaru (first generation) was sailing most of the ocean areas according to its purpose, mainly for scientific research on marine resources. It had a total length of 91.87m, a width of 15m , and the total weight was 2,644 tons.
The first encounter was on December 18, 1984, in the southwestern part of the Atlantic Ocean on the eastern side of the southern tip of the South American continent, with five crew members, including Mr. Mikio Naganobu. They encountered the objects eight times, and each time it was concluded to be a UFO, for it was obvious that there was no regularity in the speed of flight, the direction of flight, and the brightness of the light, and it was not an artificial satellite or a shooting star.
The second encounter was on December 21, 1986, approximately one month after the UFO incident over Alaska. It occurred in the waters 360 miles north of Wake Island in the central Pacific Ocean, and four crew members witnessed the object. The radar scope showed an object as large as a huge tanker, approaching from the front, flying clingingly around the Kaiyomaru twice, turning to a sharp angle, and disappearing.
Soon after that, the object that should have disappeared reappeared behind the vessel, and it suddenly approached and passed directly above.
It is obvious that it was not an airplane or a natural phenomenon because the object several hundred meters in length was moving at a very high speed, made a V-turn at a low altitude, and no sound was detected except when passing directly over Kaiyo-Maru. Therefore, we concluded that the object witnessed by crew members and captured on the radar scope was a UFO. The crew members, who were the witnesses, were highly skilled in the collection of visual observation data, and had a wealth of experience in objectively monitoring events at sea. Therefore, the UFO incident was revealed by experts in observation and research. The case was featured in the September and November 1988 issues of the scientific journal “Science.”
The twice encounters, which were hard to be said a coincidence, were conducted a detailed hearing survey by Mikio Naganobu, who was a scientist and a Doctor of Agriculture. He interviewed the eyewitnesses, and as a result of scientific analysis, he convinced himself that the objects witnessed or captured on the radar scopes were UFOs. He contributed to the scientific journal “Science” by betting on the life of a scientist.
In addition, the radar operator, Mr. Masanobu Muratsuka, was a skilled expert.
According to one hypothesis, the video captured by radar was said to be a virtual image created by U.S. military for a training to deal with Electronic Counter Measures (ECM) in anticipation of an electronic war with an enemy, and the second encounter was lightly discussed. These two valuable UFO incidents witnessed by nautical professionals including a skilled scientist were about to be buried in darkness as an imagination by the ECM.
An ECM is an interference with the normal operation of the other’s electronic equipment such as jamming, chaff, decoy, and stealth. For example, there are two methods of neutralizing anti-ship missiles launched by enemy vessels and aircraft: the “hard kill” method of shooting down missiles; the “chaff” method of firing off missiles by shooting out a large number of small objects reflecting radio waves; and the “soft kill” method of “decoying” the enemy’s missiles, which emit radio waves while floating in the air using rocket motors and make them mistake or mistake for vessels. There are two types of decoy: active decoy, which emits its own radio waves, and passive decoy, which deploys objects that do not emit radio waves but reflect radio waves in the air or at sea, making it look like a large naval vessel with a comparable target.
Recent limitations on the effectiveness of Chaff seem to mean that the fleets of various countries are combining Chaff and Decoy. The airborne decoy “Trelo” was jointly developed by IHI Aerospace, a manufacturer of domestically produced space rockets, aircraft engine components, and weapons, and a British company at the exhibition of DSEI Japan, Japan’s only fully integrated defense event, held in November 2019. Those who advocate and support the ECM hypothesis seem to have determined that the “decoy” was captured by the radar of the Kayomaru, but they have yet to develop and commercialize the decoy, which rotates around the Kayomaru at supersonic speeds of Mach 4 or higher, approaching it, and performing the V-turn, 30 years after the incident.
The radar equipped with the Kaiyomaru was capable of erasing the virtual image by switching the range. However, this flying object continued to be captured until it flew out of the range as a vivid image, regardless of the change in the range. The radar definately captured not an ECM-generated virtual image, but a UFO as a certain image.
