Frequently asked questions about this plan

Q. Is there a place to change on the day?

The ship's restrooms are used in conjunction with the changing rooms, so you can change your clothes.

Ship facilities include simple showers (water), toilets, and changing rooms (also used as restrooms) so that you can change and disembark when you disembark.

Q. What is the difference between the two?How do I get to Obama Port?

Kohama Port can be reached in about 30 minutes by ferry departing from Ishigaki Port Remote Islands Terminal.

Ferry arrival and departure times are,this way (direction close to the speaker or towards the speaker)for more information.

Q. What is the difference between the two?Is the meeting place easy to find?

After disembarking from the ferry, this is in front of the quay, which has moved to the right (north side) when looking at the Obama Port Terminal.

Our staff wearing blue polo shirts are waiting for you.

Q. What is the difference between the two?Can I snorkel even if I am not a good swimmer?

Our snorkel point is very close to where we stopped the boat, so you can see fish and coral without having to leave the boat.

We will also teach you how to properly put on the three-piece set (mask, snorkel, and fins), and the key points to remember when snorkeling, all within feet of each other, so please come and join us.Even those who are not good swimmers can enjoy snorkeling because life jackets ensure safe buoyancy.

Q. What is the difference between the two?Do I have to wear a life jacket?

For safety reasons, all guests are required to wear life jackets (life vests) or wetsuits.
Even those who can swim may suddenly have a seizure, and we believe it is necessary to ensure their safety.

We also provide life jackets for infants, so you can enjoy playing in the ocean with your small children without anxiety. With life jackets to ensure buoyancy, enjoy snorkeling safely and securely.

Q. What is the difference between the two?Are there toilets on the ship?

Each boat is equipped with a toilet. The toilet is used differently than usual, using seawater for flushing and all dumping is done underwater, so toilet paper should be thrown in the trash. (Detailed instructions on how to use these toilets will be provided at the time of your tour.)

Q. What is the difference between the two?I have poor eyesight. Do you have rental masks with glasses?

We also rent masks (one size only) with prescription (limited to those with less than 0.1 vision).

Snorkeling with a mask while wearing contact lenses is also possible. *We are not responsible for lost contact lenses.

Q. What is the difference between the two?Do you have rental items for children?

Masks, fins (21 cm or taller), life jackets (from about 100 cm in height), and wetsuits for children are also available for rent.
Floating boats are also available for infants only. (Please consult with us in the remarks column of the reservation form.)

Q. Does the infant fee include snorkel equipment rental for infants?

Rental for toddlers is included; 3-piece sets, life jackets, etc. are provided. Small children (from approx. 21 cm) are flutter-footed due to the lack of fin size.

Q. Are there toddlers who can snorkel at age 3?

Some small children can snorkel. For those who cannot, box glasses are available. For first-time snorkelers, we will practice snorkeling in shallow water where they can stand on their feet before heading to the snorkel point.

Q. Will there be someone on board to watch the children?

Basically, parents are requested to follow their children.

Q. Is there a fee to rent a floating boat?

Floating boats are available for rent free of charge. Please let us know at the time of reservation that you would like to rent a floating boat. The boats are for one person. The number of boats is limited, so please take turns with your children.

Q. How much time do we have to stay on the island and snorkel?

The tour will last approximately 1 hour on the island and 1 hour snorkeling. However, during the 1 hour stay at the island, we will practice snorkeling where you can stand on your feet (depending on the sea conditions). You will have about 30 minutes of free time to spend at your own leisure.

If you want to spend more time on the Island of IllusionsCruising to the mysterious island "Hamashima" (No.635)Please consider the following.

Q. What is the approximate depth of the ocean for snorkeling?

The depth of the snorkel point is approximately 3-5 meters.

Q. Can I participate during pregnancy?

Pregnant women are welcome to participate in snorkeling after consulting with your health care provider.

However, we may decline the offer depending on the sea conditions. We appreciate your understanding.

It was helpful that I was able to join the tour by making a reservation on the same day. It was a great day, and we were able to make good use of the time we had available due to a sudden change of plans. The snorkeling at Shihsi lagoon was wonderful, not to mention the spectacular view of the Phantom Island. Although we did not see sea turtles, we were happy to see other abundant sea creatures. Thanks to the knowledge and support of the guides, we were able to enjoy the trip safely.
