My home's gas stove has become old and difficult to ignite, so I replaced it. During the replacement, I cleaned the area, and the gas stove was unusable for about a day. I could have just installed the new stove without cleaning, but instead, I used a cassette gas stove with a gas cylinder as a temporary replacement. At that moment, while holding the gas cylinder, I had a vision of the future (though I don't know when).
The vision was: "I'm keeping two cylinders on hand for emergencies, but I'll have to use them sparingly." Then, a few days later, "At first, I thought two cylinders would be enough, but they're running out faster than I expected. Maybe I'm using them too much? I don't feel like I'm wasting them, though." Then, "I remember! I used one cylinder a while ago and saved the rest. So, that one had some gas left. The other one was new, but it also ran out quickly. I think I can manage without it, but I wish I had more on hand so I could use gas normally." After that, more images came to mind, and it seems that, instead of a major disaster, there will be a situation where gas is unavailable for a while, causing some inconvenience, but eventually, it will be restored.
It seems that I will need to use the cassette gas stove again in the future, perhaps during a smaller-scale disaster. When I held the gas cylinder, I felt a connection to the future, to the feeling of using that tool. The fact that I'm using it at home suggests that my house hasn't suffered much damage, but even with a moderate earthquake, gas pipes can break, and gas service may be unavailable for a while due to equipment inspections.
Two cylinders might be enough, but this experience led me to buy three (sets) today. I think that should be sufficient. I don't know when this will happen, but the two cylinders I have now can be saved and used for a certain period, so it seems like it will be in the near future (within 10 years?). And, I think gas service will probably be restored normally.
The duration of the outage seems to be neither too short nor too long, perhaps a few days to a week or ten days. At least in the area where I live, the outage is likely to be that long, mainly for infrastructure inspections, but the damage to buildings and people is relatively minor. This is specific to my area. I don't know about other areas, but I think the damage will be around what is generally said in the news. I think I'll feel something like, "Ah, so that's the kind of damage that happens. The local government had designated hazard zones, and they seem to be quite accurate. The designated hazard zones are indeed experiencing damage." There will probably be some margin of error, but I think it's generally in line with the local government's hazard map.
This has nothing to do with the recent rumors in the speaker industry about a submarine earthquake and tsunami off the coast of the Philippines in July 2025. It's simply the type of event that is commonly talked about in the world, such as the Tokai earthquake, the Nankai Trough earthquake, or the Great Kanto Earthquake in the Miura Peninsula. I have some general ideas about each of these, but I have no clues as to which one is related to the gas cylinders this time, so I don't know which one it is. However, based on the feeling that the epicenter is south of Tokyo, anything is possible.
The content feels like "Ah, it's finally here," so there's no particular surprise. It seems that the event occurred normally, and people were dealing with it calmly. Therefore, there's no particular surprise, and there are no elements that would cause a buzz like in the news. The disaster occurred quietly, and people dealt with it quietly. The hazard maps were largely accurate, and the response was carried out calmly as planned. Of course, there were various damages and it was sad, but there was no particular panic, and people seem to be accepting it calmly.
I'm saying this because, in reality, it's not certain whether it will actually happen. However, if you just refill a few gas cylinders and keep them on hand, it doesn't take up much space and doesn't cause any particular problems, so it's good to do what you can. Gas cylinders can be used anywhere. Also, it would be good to have a little bit of long-lasting food on hand. I always buy water in boxes, so a short period is fine, so I'll just leave it as is.
It is expected that the coastal areas will be washed away by the Tokai earthquake, and if it happens, it will be a fairly common and predictable scenario. People who have a bad feeling about it will probably have moved from the coastal areas by that time, and things will work out somehow. As for those who remain in the coastal areas... there will be various reasons, so there's no need to worry about it particularly. I don't need to tell those people anything; I think people living in dangerous areas are already being told various things by the local government every year. Especially in areas like Shizuoka, the region is constantly bombarded with "It's coming, it's coming" on television, and even if it's not every year, it's every six months or every few months, with tragic images being reported on "Disaster Day" and so on, so people's ears must be full.
Therefore, people living in the affected areas are already aware of it, and I think the damage will be largely as expected. For me, who live in a region other than that, it's enough to just keep a few things on hand as a precaution. That's the extent of it for me.
Even so, I don't actually know what will happen.
In either case, if it really happens, it will just be what it will be. There's no point in worrying. Those who are saved will be saved, and those who die will die. That's all there is to it. Just don't worry about it, live each day to the fullest, do what you want to do, and live a life that is enjoyable and free of regrets. It's about living a normal life.
