Miracle “Iriomote Island” has nurtured a unique ecosystem from time immemorial.

We islanders think that we’d like to leave this gift from nature to future generations in response to the fact that Iriomote Island has become a World Natural Heritage Site.

We strongly hope that many people from all over the world could know about Iriomote Island, where the ancient ecosystem still exists and that they could cooperate with our efforts to protect the great nature of this island.

They sell minimum necessary commodities, unlike convenience stores or supermarkets in the metropolitan area. We recommend you to buy foodstuffs for barbeque or marine goods, etc. at Ishigaki Island before coming to this island.

About temperature, outfits and UV protection.

Although Iriomote Island may be considered as an island of perpetual summer, actually the average temperature in November through March is 18 to 20 degrees Celsius, so it is a bit cold for wearing a short sleeve shirt.

Then, it becomes real summer in April through October and the average temperature is around 30 degrees Celsius that is appropriate to say the perpetual summer.

Be sure to prepare sun glasses, sunscreen, UV protective outfits and so on, since UV rays are very strong.

For those who keep their guard down like, “it’s OK because I often go to the sea in summer”

The UV rays in Yaeyama district are different. Be sure to wear a rash guard when playing in the sea, especially children are recommended to be well prepared to avoid being too painful to move on after the second day due to sunburn of the first day.

About typhoon

Iriomote Island means a typhoon often heads towards, you can see typhoons come close in July through October, according to the statistics from the past ten years.

It usually passes through this island with higher strength before hitting Honshu Island. You may see a car rolled over on TV News, that scene happens year after year in Iriomote Island.

As a typhoon approaches, following things happen on a daily basis.

  • Various kinds of objects are blown by the strong wind. (Cars and containers may be moved and rolled over)
  • Power outage and Water outage may occur when typhoon passes through. (It takes a couple of days to recover and this happens a few times per year.)
  • Obviously, ferries are cancelled, so people cannot get on or off the island.

Also, if people are affected by typhoons (cannot get on or off the island), special “typhoon” prices will be offered by Hotels and accommodations. That is a common thing in the Okinawa area. (It’s a bit cheaper than usual.)

If you come to this island and the return ferry is cancelled, please let us know that you cannot go home due to the typhoon when booking extra nights.

About mobile phone and Wi-fi

There are no mobile carriers that cover the entire Iriomote Island.

You can use a mobile phone in the main part of the island, however there are many no reception areas when going into a forest or hinterland.

Also, there is no free Wi-fi. Please contact each hotel or accommodation beforehand.

One or two persons become missing when going into native forest without a help of a tour guide every year.

Even islanders who know everything about this island, can get disoriented when entering native forest.

Please be aware that it is difficult to search through when you are missing.

As written in the following paragraph about transport, Iriomote Island is the second largest island in Okinawa prefecture.

Since most of the area of this island is native forest, it is extremely difficult to search through when you get lost due to the lack of cell reception.

About transport

It is not so known that Iriomote Island is the second largest island in Okinawa prefecture.

Because of that, it is difficult to get around on foot. Rental cars and rental bikes are the main ways of transportation.

It is recommended to use the shuttle bus of hotels or buses by activity facilities for those who have already decided their destination or have limited range of action. (Please contact each facility beforehand.)

There are no trains, but buses are available.

The speed limit is always 40km per hour. (Partly 30km per hour in some village area.)

You may encounter wild animals including Iriomote wild cats at night, so please slow down the speed at so called “island speed”.

Some elementary school students come to this island with starry eyes saying “My summer homework is to observe Iriomote wild cats.”

Sorry !

Even islanders rarely see “Iriomote wild cats”.

So it’s a “miracle” if you could see them.

It’s a “super miracle” if you could take pictures or videos.

Please post on Instagram if you could.

There is only one traffic light on the island.

Do you know the reason why one traffic signal here?

This is because children who haven’t seen traffic lights will not have any trouble when they become adults.

For this reason, only one traffic light is placed in front of an elementary school.

If you see the red light, it might be when children want to cross the street.

Please pay careful attention and be kind.
