 For first-time visitors

attitude towards nature 

Swimming with dolphins means entering the field of the sea against nature.

All outdoor activities, including dolphin swimming, are done at your own risk.

Please do not overestimate your physical strength and swimming ability and enjoy it within a reasonable range.

Let's keep dolphin swim friendly to dolphins

The dolphins on Mikurashima are friendly, but we are in the position of interfering with their lives.

Follow the rules and manners and do a gentle dolphin swim so as not to disturb the lives of the dolphins.

Please be sure to read it!

 🔸Dolphin swim precautions and rules

* If you do only one dolphin swim, you may end up not seeing each other.

Therefore, the basic schedule includes two dolphin swims.
Sometimes the dolphins are in a good mood and other times they just ignore you.

Also, it depends on the weather, so when the sea is rough, you may end up not seeing dolphins.

There may be times when the boat cannot be sailed due to stormy weather, but all dolphin boats are fully booked, so even if it is canceled, it cannot be changed.

Dolphins behave differently every time they enter the sea, so we recommend making reservations as many times as possible.

Even the sea like this when it's calm

This is what happens when it's rough

Participation for first-timers and children

◆If you are a beginner, please be sure to attend the training.

About wearing a wet suit
I often get the question, Do I need a wetsuit even in the summer?
Wetsuits not only keep you warm, but they also play a major role in securing buoyancy.

A wet suit is a buoyant body that can replace a life jacket in an emergency.

We do not require you to wear a wet suit,
Swimming in a rash guard or swimsuit
[open seaOnly those who are experienced enough to dolphin swim or snorkel in the water and are strong swimmers]
[Able to swim more than 100m even when the legs are cramped or in the ocean with waves, and to be able to tread water for 10 minutes]

is a condition.

For those who are unfamiliar with snorkeling or beginners, please be sure to wear a wet suit for safety.
If you don't like wetsuits, or if you can't
afford to wear a wetsuit, you will be asked to wear a life jacket.
(Rental suit is up to height 190cm and weight 90kg)

In the case of staying overnight on Miyakejima, it is mandatory to wear a wet suit. Those who do not have a wetsuit cannot board the boat.

◆ For those with children (as a general rule, 4th grade or older: Summer only/June to September)

The sea of Mikurashima Island has many days with rough waves, so it cannot be said to be calm.

Dolphin swimming involves jumping from a boat into the open sea where you can't stand tall, so even if you can swim in the pool, children who aren't used to the sea often can't do it because they are afraid.Please consider the degree of accustomed to the sea when children participate.

In addition, in spring and autumn, the waves are particularly rough and the water temperature is low, so we ask that children refrain from participating for safety reasons.

Jellyfish prevention cream/sunscreen

​◆ There are jellyfish in the sea regardless of the season.

Not only does it hurt when you get stung, but if it is highly toxic, you may get numbness and difficulty breathing, and you may be sent to the hospital.

Even in summer, avoid exposing your skin as much as possible, and apply anti-jellyfish cream to areas where skin is exposed, such as your face.

It minimizes damage in the unlikely event that you are stung.

​◆ Dolphin swims are exposed to the sun for about two hours.

Be sure to wear sunscreen, especially in the summer when the UV rays are strong.

There are many types of underwater masks, but they differ in size, material and shape of the part that touches the face.

If it does not fit your face, water will easily enter and it will be difficult to use, so be careful when purchasing.

Choose a silicone material for the part that touches your face.
​ We recommend a lens with a small inner volume and a short distance between the face and the lens because it has a wide field of view and is easy to clear the mask.

Choose a snorkel that is easy to hold and easy to clear when water comes in.

 GULL Layla Stable(for women)canal stable(for men) is recommended.

Cheap ones are fine, but those with a valve at the top to prevent water from entering are only for playing on the surface of the water.

It cannot be used for dolphin swimming or skin diving as there is a risk of suffocation when diving underwater.

It is important to choose fins that match your leg strength, swimming ability, and level. We recommend the full-foot type, which is not a strap type, and is made of rubber.
Plastic fins and diving fins are not recommended as they make it difficult to swim on the surface and make you tired.


GULL Emden: small fins for beginners

Gull Mew: Best-selling fins that can be used by everyone from beginners to advanced users! Best recommendation!

GULL Warp Fin: For intermediate to advanced students who have graduated from MU.
​ *Super Mew is for scuba diving and difficult to use for dolphin swimming.

Gull Barracuda: The world's highest grade rubber fin boasting excellent propulsion and ease of use for intermediate to advanced users!

* Many carbon fins and plastic fins for free diving such as leader fins lack repulsive force, making it difficult to turn and not effective for small turns, so we do not recommend them for dolphin swimming. Also, fins with sharp ends may inadvertently injure dolphins or people around them, so please fully understand the characteristics of the fins before using them.

Wetsuits play an important role in retaining heat and ensuring buoyancy. (It will replace the life jacket when I say yes)

Depending on the material of the fabric, the price may be on the low side, but high-quality fabrics have the advantage of being warm and elastic and easy to move around in. There is a marked difference in heat retention and mobility between ready-made sizes and custom-made ones that are made to fit your measurements.

When purchasing, please consult us to choose a solid one.

For skin diving in the summer when the water temperature is high or at a resortTupperware (jacket type), which is only for the upper body, is fine.

Weight when wearing a wet suit (weight)is required.

The amount of weight varies from person to person, so be sure to keep track of it during practice.
