Beaches on Miyako Island with High Accident Rates and Why They're Dangerous
On Miyako Island,A popular beach where many people go snorkeling on their ownAccidents continue to occur there.
Here, we'll introduce the beaches where accidents have been reported and explain why accidents are likely to occur there.
Shinshiro Coast
Shinshiro Beach is a popular spot where many people enjoy snorkeling on their own because the water is shallow and the waves are calm.
On the other hand,In 2026 alone, there have been a series of accidents in April, September, and October.The following is a list of the most common problems with the "C" in the "C" column.
In the September incident, he was swept away by the wind and ocean currents about 200 meters offshore and was unable to return to shore on his own.
Even on days when the sea looks calm, don't go too far out, and be sure to wear a life jacket and go in with others.
Sunayama Beach
Sunayama Beach is a popular photo spot thanks to its arch-shaped rock, butThere are no on-site supervisorsIt's the beach.
Even though the water appears shallow, there are areas where the current changes easily, and because it is located on the northwest side of the island, waves tend to get higher in winter when the north wind picks up.
In the past, following reports of shark sightings, Miyakojima City has installed signs urging caution.
When swimming, stay close to the shore, and avoid going into the ocean on days when the waves are high.
Around Irabu Island and Shimoji Island
The area around Irabu Island and Shimoji Island is home to many snorkeling spots with abundant fish and crystal-clear waters.
The rocky and coral terrain is intricate, andA spot where the water suddenly gets deep once you go a little way out to seaThere are also
Accidents occurred near the coast of Nakanoshima in May 2026 and in the waters north of Shimojishima in May 2022.
If you're not familiar with the terrain or the tidal currents, it's safest to enjoy the experience on a guided tour.
At PiPi, at the "Sapphire Cave"—the Blue Cave on Irabu Island—Guided Snorkeling TourWe are holding an event.
Main Causes of Water Accidents
While there are various causes of water-related accidents, they can generally be categorized as “lack of knowledge about the ocean” and “inadequate equipment.”
Both of these are causes that can be prevented if you know about them in advance.
Lack of Knowledge About the Ocean
The conditions of the ocean in Okinawa change every day depending on the tides, wind direction, and the topography of the coral reefs.
Without knowing what the ocean conditions were like that day,It's very dangerous to go into the ocean alone.It is.
Since it’s possible to find yourself drifting out to sea before you even realize it, a good understanding of the ocean is essential if you’re snorkeling on your own.
Lack of equipment, such as life jackets
According to the Miyako Island Coast Guard, approximately 90 percent of those who died in accidents while engaging in marine leisure activities were not wearing life jackets.
When snorkeling, be sure to wear flotation gear, such as a life jacket.
In addition, life jackets will not be fully effective unless they are worn correctly.
How to Use Snorkeling Equipment Properly
You can only enjoy snorkeling safely if you use the equipment correctly.
Here,Diving mask, snorkel, life jacket, finsHere are some tips on how to use it.
Mask and Snorkel
Before using them, check the mask for cracks or chips and make sure the snorkel isn't broken.
When wearing a mask, make sure your bangs don't get inside the mask—this will help keep water out and prevent the mask from fogging up.
① Open your mouth wide as if saying “A”
② Form your mouth into an “i” shape and gently bite down on the mouthpiece with your teeth.
③ Form your mouth into a "u" shape and wrap your lips around the outside of the mouthpiece.
Before you start swimming, dip your face in the water once, andDoes water get into the mask? Can I breathe properly?Let's head out to sea after checking that.
life jacket
When choosing a life jacket, make sure to select one that fits your body, andTighten all the straps so they fit snugly against your bodyIt is important to
If it remains loose, there is a risk that the life jacket will float away on its own or slip off while you are in the water.
fin
Wearing fins allows you to move forward with less effort, so you can enjoy snorkeling more easily.
Fins come in two types: full-foot fins, which are worn barefoot, and strap fins, which are worn over shoes.
It's easy to fall if you walk while wearing fins, so,Put them on after you get into the waterThat's safer.
Essential Knowledge About the Ocean to Help Prevent Accidents
The ocean isn't always in the same condition every day.
Even on sunny days, there are times when the current or wind is strong, so,Check not only the weather but also the sea conditionsLet's go into the ocean after that.
Tides
The ocean experiences high and low tides throughout the day, and the water depth varies significantly depending on the time of day.
According to the tide table for Miyako Island (Taira), there are many days when the difference between high tide and low tide exceeds 1.5 meters.
In the shallow waters off Miyako Island, when the tide goes out, the coral is exposed almost to the surface of the water, andIt becomes harder to return from the open water to shoreThere are times when
Before going into the ocean, be sure to check the tide table to see when high tide and low tide occur.
Reef current (rip current)
One thing to be especially careful of in the waters off Okinawa is the current flowing out to sea from the gaps in the coral reefs.Leaf CurrentIt is.
Waves roll in from the open sea toward the shore, but when the seawater that has washed ashore rushes back out to sea all at once through gaps in the coral reef, it creates a strong current.
If you get swept away by the current, don't try to swim directly toward the shore; instead, swim parallel to the shore, cutting across the current, to get out of it.
If you can't swim, it's important not to overexert yourself; instead, float and conserve your energy while waiting for help.
Ensure means of communication
When you're enjoying the ocean, make sure you have a way to contact someone so you can call for help right away in case of an emergency.
Put your smartphone in a waterproof case, andAway to get in touch with people on land right awayIt's best to leave it that way for peace of mind.
Accidents or incidents at sea can be reported to the Japan Coast Guard’s emergency hotline at “118.”
Hazardous marine organisms

Do not touch or approach animals carelessly, andAt the very least, try to remember which creatures are highly venomous.That's reassuring.

・Okinawa Prefecture issues a warning about box jellyfish every year; in 2026, the warning period ran from June 1 to September 30.
• If you are stung, get out of the water immediately. Do not rub the affected area; pour plenty of vinegar on it, gently remove the tentacles, cool the area, and then seek medical attention.
・Characterized by its blue float and long tentacles, it is sometimes washed ashore by strong winds.
・When stung, you feel a sharp pain, like an electric shock.
・If you are stung, rinse the tentacles off with seawater to cool the area, and seek medical attention (never use vinegar).
・The spines on the dorsal, anal, and caudal fins are poisonous, and a sting causes severe pain.
・Since they move slowly and don't run away, be careful not to accidentally get too close.
・If you are stung, remove any visible stingers, soak the affected area in water at a temperature of about 40–45°C, and then seek medical attention (be careful not to burn yourself).
・Although they are generally docile and rarely attack people, they are members of the cobra family and possess a potent neurotoxin.
・If you accidentally step on or grab it, it may bite you.
・If you are bitten, get out of the water immediately, clean the wound, and go to a medical facility right away.
