I received information that there will be an earthquake within the next few days in Tokyo. I had been avoiding elevators as much as possible, and we just had an earthquake a moment ago. It gave me goosebumps.

I received information about a potential earthquake in Nagano, and they just had an earthquake with a seismic intensity of 5 there. I applaud you for the accuracy of your service.

My elementary school-aged daughter was studying about clouds at school and she told me that she and her friends saw “earthquake clouds” on the way home from school one day.
It was Tuesday when she told me this, and when I checked the earthquake prediction site, there was a post that predicted an earthquake in the Kanto Region on the upcoming weekend.
We were out shopping as a family in the afternoon on Sunday, and felt the shakes. I was not only impressed by my daughter but was also amazed by the accuracy of the prediction.
(Automobile company employee)

We have various hazardous materials at our factory. Executives from our head office came to the factory on Wednesday and told us that they saw a prediction of an earthquake happening in the Kanto region soon. We were told to check for all of the hazardous materials and review safety procedures.
We were in the middle of our busy season, and we did not trust the earthquake prediction information. However, we had to follow the instructions given to us by company executives as they were direct orders, so we reluctantly performed safety inspections inside our factory. Three days later on Saturday, we were surprised when an actual earthquake occurred.
(Medium-sized factory manager)

I am a technical manager of a factory that has more than 2000 people, and I am also in charge of disaster prevention. In the case of an epicentral earthquake, it is my job to protect the safety of as many employees as possible. So I looked at all the options to get the best earthquake prevention information available.
As a result of my research, I found out about the “Reverse Radio” system in which earthquake detections can be made by analyzing the electromagnetic noise. So I became a member.
(Technical manager of a large manufacturer)

Our company has many facilities throughout Japan. Since I was appointed the person in charge of disaster prevention, I have become a member of the Reverse Radio earthquake prevention system that uses electromagnetic noise.
One Friday, we received an emergency email from the system indicating there was going to be a big earthquake somewhere around Tokyo. In the morning on Sunday, I received another emergency email to warn us about the earthquake. Although it was my day off, I contacted some of the managers of our facilities that are located in Tokyo.
That night, there was a big earthquake. I had the facility managers check to see if there were any problems, but since we were all in standby, I was able to get in touch with everyone immediately.
(Facility manager)

I work at a machinery factory and I was assembling a machine that was 4 meters high.
One of our executives heard the earthquake prediction and told us that we needed to secure all the tall machines with ropes.
2 days later, an actual earthquake happened but none of the machines fell.
(Machine manufacturer factory employee)

Our company decided to test the Reverse Radio earthquake prediction system that uses electromagnetic noise. Since I am in charge of disaster prevention, I was assigned to a task that requires me to check the website every morning and report to my superiors.
There had been no abnormalities for over a month and I started to feel that the system was nothing spectacular, if not boring. Then one morning, it gave me data that was drastically different from what I had been getting.
The data showed an upward trend the next day, and for several days after that, then it started to go down. After the peak, it kept going downward, and it eventually went back to the original position.
I had heard that the abnormalities in the data meant that it was the process of the noise level increasing, hitting a peak then declining. I also heard that they would predict a potential earthquake. I reported this to my superior, and sure enough, an earthquake occurred 2 days later. The shakes were relatively small but I was so surprised by the prediction that it gave me the chills.
(Person in charge of disaster prevention at a large factory)

Thank you for your continuous support.
The earthquake prediction in Chiba was spot-on. I had always been scared of earthquake predictions I saw on TV, especially those that are epicentral and the size of M8 or larger. But getting the prediction in advance has helped me shed any unnecessary fears. Also, your precise and thorough predictions are very helpful. Thank you so much.

I always refer to the data. Most of the information I receive by email is very accurate, and helps me prepare mentally. I am very impressed.

The emergency email you sent me predicting the earthquake was spot-on. Thank you so much.

I was taking precautions as I received several emails from you, but I felt the shakes just now. It was spot-on. Bravo!

I really appreciate the emergency email communications. Because of those emergency emails, I was mentally prepared and had also brought my valuables and emergency kit with me when I went out.
The location of the earthquake was spot-on and the magnitude was less than 6 but it was good that it wasn't that big. I hope you will continue to help us in the future.

Thank you so much for continuing to provide analysis and for sharing the information with us. The emergency emails you sent us on the 27th and today helped me prepare for the earthquake warning that was released earlier for the Northwest part of Chiba Prefecture. I was able to respond without panicking.
The magnitude was smaller than predicted but the prediction was spot-on. Please do not hesitate to send us emergency emails when we need to be prepared like this time. Don't mind if your predictions may not always be spot-on.

When I felt the ground shake, my husband shouted “Earthquake!!” I said to my husband, “I received an alert for this earthquake and it will be OK.” I am the only member of this service in my family, so my husband looked very confused by my comment.
