• Guests who are minors must bring a consent form signed by a family member on the day of the event; guests aged 12 or under must be accompanied by a parent.
• We apologize that passengers under the age of 6 and those aged 60 or above are not allowed to participate in water activities.
• For safety reasons, we do not accept registrations from high-risk individuals such as those with acrophobia, claustrophobia, the elderly, those prone to joint dislocation, osteoporosis, pregnant women, those with physical disabilities, mobility impairments, or those who have consumed alcohol, are hungover, have epilepsy, or have diabetes.

• This is a same-day round trip; the return date cannot be changed. We apologize for the inconvenience.
• If you and your friends/family book separate swimming tours at Aharen Beach and Tokashiki Beach, you will be transported to the beaches separately by private vehicles after arriving at Tokashiki Island, except during the boat trip. You will not meet each other during this time (there is no public transportation connecting the two beaches). Please be aware of this.

[Instructions for Booking High-Speed ​​Ferry and Cargo Services]

• The meeting point for high-speed ferries and boats is the lobby on the first floor of the ferry terminal at Naha Port. Please confirm the meeting point and time before making a reservation.
• After you check in, the staff will give you your round-trip ferry ticket. Please keep your ticket safe and board the ship by yourself.
• Since the boarding location is some distance from the check-in area, please be sure to check in on time. No refunds will be given for late arrivals due to personal reasons.
• As the ferry company only releases the day's sailing schedule at 8:00 AM on the day of the event, and we also need to confirm with the island staff whether it is safe to conduct the activities, the event may be cancelled only on the day of the event. Unless otherwise notified, departure will proceed as scheduled. Please check for updates before your trip. Thank you.

[Instructions for Booking Dedicated Vessel Solutions]

• There are no places to put luggage at the meeting point, on the dedicated boat, or on the island's shuttle buses. Please do not bring suitcases or large luggage to the event.
• Please be aware that the activity may be delayed or end earlier due to sea conditions and weather on the day.
• The minimum number of participants is 10 adults. If the minimum number is not reached, the activity will be cancelled, and we will notify you no later than one day before the trip.
• If you and your family/friends make separate reservations, please be sure to use the same representative's name, or inform all accompanying persons of their order numbers in advance via the message box, to avoid being assigned to different boats on the day of the activity. If you do not inform us in advance, you may be assigned to different boats on the day, and we will not be able to make adjustments for you on the spot. Please be aware of this.
