Frequently Asked Questions (FAQs) about MARUYU

Q. Should I definitely choose MARUYU?

Not absolutely, but strongly recommended.

We recommend that you do not hesitate to choose a Maruyu operator, especially if it is your first time or if you have small children or elderly companions.

While it's not a "must choose."It's a good choice.The "Maruyu" is a "Maruyu".

Please consider this as an option to make your trip more comfortable, including a peace of mind fee.

Q. Won't the price be higher?

It is not necessarily higher.

The tours of Maruyu operators are not set at a particularly high price, but most are in the same price range as other companies, depending on the content and time required.

Be wary of extremely inexpensive tours, however.

As mentioned above, there are cases where safety equipment and guiding systems are inadequate because they are "cheap or inadequate,It is important to choose the best choice based on content and safety measures rather than price.It is.

The fee will not be excessively high just because it is MARUYU, and even if it is a few hundred to a thousand yen more expensive, it is not expensive if you consider it as a peace of mind fee.

Q. What is the difference between a non-certified business and a certified business?

The level of trust in safety measures is different. While non-certified tours do not necessarily mean that the activity tour is immediately inadmissible, it is true that safety awareness varies due to the ease of entry into the activity tour market.

The biggest difference is whether or not they are checked by a third party (police). While Maruyu vendors receive guidance from the police, including unannounced annual inspections, uncertified vendors are basically responsible for their own safety.

In terms of accident rates, according to police reports, there have been very few cases of serious accidents after acquiring MARUYU.

In general, the difference is that MARUYU has a "guarantee of trust," which saves the user the trouble of finding out for himself whether it is safe or not.

I think it offers good value for the price. Being able to charter a boat for half a day and request specific spots you want to visit is a huge draw for group trips. That said, if I had to nitpick, the boat did rock a bit, so I think people who get seasick easily should take precautions beforehand. The ocean was absolutely beautiful.

The facilities were great. It was convenient to be able to board the boat without getting wet and head out to see the sunset on the “Mysterious Island.” If I had to nitpick, it was a bit of a shame that there were some clouds, but the view was beautiful.

First, we took a boat to the “Mythical Island” and fully enjoyed the white sandy beaches and crystal-clear blue sea. After that, we headed to the mangrove river to try stand-up paddleboarding (SUP), where we breathed in the fresh air of nature surrounded by silence and felt completely refreshed. We had a truly fulfilling day from start to finish, and it became a wonderful memory.
