Earthquakes in Japan: What You Should Know

If you know anything about Japan, you may already be familiar with how frequently earthquakes strike this small island nation. Japan experiences thousands of earthquakes every year due to its location directly on top of several tectonic plates along the Pacific Ring of Fire, one of the most seismically active zones in the world.

Living in Japan means you must be aware of the risk of natural disasters, including earthquakes, tsunamis, and typhoons. However, being informed is the best way to stay calm and safe.

Earthquakes in Manga? Yup!

If you’re into classic manga, you might know “Watashi ga Mita Mirai” (The Future I Saw) by Ryo Tatsuki. In this eerie and fascinating manga, the author allegedly predicts several major world events—including a massive earthquake predicted to occur in 2025.

I’m not going to lie: I got paranoid after reading more about this manga and how surprisingly accurate some of her previous predictions were. Of course, no one can know for sure if or when a big earthquake will happen, but there’s always value in being prepared—and that starts with knowledge.

What’s the Nankai Trough?

Japan’s government highlights areas at risk of a major quake, especially along the Nankai Trough.

 

One reason people in Japan are especially on edge lately is due to the Nankai Trough Earthquake cycle.

Over the past 1,400 years, a major earthquake along the Nankai Trough has occurred every 100 to 200 years. The last one? Roughly 80 to 100 years ago. That means we’re quickly approaching the high-risk window for the next big one.

In simple terms: when an earthquake occurs along this trench, the tectonic plates involved snap back into place and begin building pressure again—pressure that eventually leads to another quake. Scientists and disaster officials are urging people in Japan to prepare now, especially those living in coastal regions or major cities like Osaka, Kyoto, Kobe, Nagoya, and Tokyo.

Earthquake Preparation: Don’t Panic, Prepare!

Don’t be scared. That’s the most important thing to remember. You’ve got the most powerful weapon on your side: knowledge.

Knowing what to do, where to go, and how to prepare an emergency earthquake survival kit will help you stay calm and keep the people around you safe too.

Now class, let’s begin our Earthquake Preparedness 101.

Having a well-stocked emergency earthquake bag (防災バッグ) is one of the smartest things you can do while living in Japan—or anywhere prone to natural disasters.

Keep your disaster kit near the front door or somewhere you can grab it easily in an emergency evacuation. Whether you buy one or build one, your go-bag should include these essentials:

One of the most crucial parts of earthquake preparation is knowing where to evacuate.

Look up your designated evacuation center (避難所 – hinanjo) online or go directly to your local City Hall to ask for printed materials in English or Japanese.

Here is a link to a website in the Kansai area (for those that live here) where you can check for evacuation areas in Osaka.

What To Do in an Earthquake

Ground rupture is one of the many visible effects of major earthquakes.

 

Indoors During An Earthquake

  • Go under a study object, such as a table or desk, and put your hands and arms over your head, and tuck yourself into a crouch.
  • If your bookshelves and TV are not secured to the wall, make sure to stay away from those items. <This may be a good time to secure them to the wall so that they do not fall or break during an earthquake>
  • Until the earthquake has stopped, please be sure to stay inside your home

 

Outdoors During an Earthquake

  • If you can get to a safe and open space, be sure to get there and away from huge objects like trees, buildings, and electrical poles.
  • If you can’t get to an open area, get on your hands and knees, put your hands over your head, and cover yourself.
  • Stay put and stay calm until the shaking stops!

Happy Staying Safe!
