I ran a google translate of the Q&A page on their website and this is just fascinating:
Q & A
Q, Is orca float clean? Isn't it unsanitary?
A. In our shop, we thoroughly wash with clean running water until we can get rid of the killer whale float.
Please be assured that you can use it clean at festivals where you are used.
Q, After all, what are you?
A, food sales, play equipment rental, rental space, amusement facilities.
Due to the nature of lending places and tools, things like Internet cafes are close as business conditions.
There is no restaurant or accommodation, so there is no provision of cooking products.
Q, I would like to bring in a costume, is it possible?
A, it is not possible to recommend too much because the store area is not very large, but it is possible.
If you can say so at the time of booking, we will prepare for your request as much as possible.
Q, I would like to cancel my reservation ...
A, I do not currently have a penalty for cancellation, but I would like you to give notice of cancellation by 24 hours before the reservation time.
Also, if there are too many cancellations, some measures or penalties may be set.
Q, Do you have a shower?
A, Yes, we have a common hot-water shower and can be used free of charge by our shoppers. Shampoo, rinse, body soap and hair dryer are also available free of charge.
Q, Should I have the reserved time from the beginning to the end?
A. The use of the usage time at the time of booking is for ease of booking management, so it does not mean that you must stay from the beginning to the end of the booked time. In addition, calculation of usage time rate is calculated from the time spent in the shop. Depending on the shop owner's plan, you can use it longer than the reserved time.
Q, I'm embarrassing naked ...
A. We sell men's swimwear, women's swimwear and full-length tights at our store.
There is a possibility that the size does not fit, so it is recommended to be brought.
Q, I would like to go with my friends, but how many people can use at the same time?
A. Up to three people can enter the store at the same time, but it is not possible to use three or more floats simultaneously.
In addition, we do not recommend it because the store area is small and charges will occur separately for each person.
Please think of it as the same charge as using one by one separately.
If you use the tour only, you will only be charged for the stay time.
Q, the address posted on the access page is ambiguous
A, The detailed address is daringly down to prevent it from coming to the store suddenly without a reservation.
When customers who have made reservations in advance visit the store, the shopkeeper will meet you to the nearest station, JR Shimogizo Station.
Q, Is there anything better to bring?
A, there is no problem even if you are basically out of hand. We offer bath towels, face towels, toothbrushes, shavers, food, etc. for sale in our shop. Of course you can bring it with you, but it would be nice if you could buy food and drink at our shop.
Q, I want to know the flow of leaving from entering the store.
A, When you enter the store, ask for explanations and notes on the store's system and sign the consent form. We will then choose predator plans and gastric juice options, and if necessary, additional options, to settle the down payment. We will reimburse as use money and the price of additional purchases at the time of withdrawal from the store and will be withdrawn.
Q, how much does it cost to include everything?
A, It depends on the usage time and plan, but it costs at least 12,000 yen at least (White turbid stomach mucus, basic plan, 11,880 yen tax included for less than 1 hour)
I also recommend that you bring around 20,000 to 30,000 yen to have a leisurely enjoyment.
Q, Is it possible to pay by card?
A, I am sorry, but I do not correspond at present. It may correspond in the future.
Q, Do you have shops near supermarkets and convenience stores nearby?
A, there is a convenience store near 10 minutes on foot, but it's a bit far from walking.
In order to prevent the trouble of disappearance from the end of the store, I am glad if you can buy food and drink at our shop.
