Yonaguni Tour! Ocean Adventures
Weather: Cloudy Temperature: 19℃ Water Temperature: -
Hi there! This is TAISHIRO☺︎ from the Ishigaki Island store!
Thank you for waiting! Today, I'd like to talk about the Yonaguni tour!
It was TAIshirou's first time leading a tour alone. I was incredibly nervous...
But it was a truly enjoyable four days! ![]()
I'm so relieved that we finished without any incidents ![]()
The goal of this Yonaguni tour was, of course, hammerhead sharks and the underwater ruins!!

This time, the wind wasn't on our side, but we managed to go anyway!!


We're all fired up ![]()
So, let's gooo!!

The sea of Yonaguni, different from our home waters...
Personally, I thought it was quite challenging ![]()
I was a bit clumsy away from home, but I still kept my spirits up!!!!

Towards the dream hammer river!!!
We swam letting the current carry us, but...

However... no matter how long we waited, the hammerheads didn't show up...
And then...

The first day ended in disappointment with no hammerheads... ![]()
It's a shame, but it's an activity dependent on nature, after all...
We'll reset and look forward to tomorrow!!!

The next day was the long-awaited underwater ruins!!! ![]()
Everyone said they wanted to go here, so we went as planned!!

As soon as we entered the water, the topography felt different from Ishigaki Island...
It felt like an ancient sea ![]()


Everyone enjoyed the topography, but...
The current was raging!!!!
As expected from the holy land of drift diving...
Even I was surprised by the intense current for the first time ![]()
I felt like I received Yonaguni's initiation ceremony www

After enjoying the ruins, we took a lunch break!!

Since we return to the boat after each dive, it's easy even in winter ![]()
We ate and warmed up!!
And after that, it was time for a hammerhead revenge!!!

This time, please appear~?!!

They're here!!! Huge hammerheads!!!
They're plump and big!!!
Everyone's excitement was at its peak with the powerful hammerheads ![]()

It's a bit far, but there's a hammerhead river on the seabed!!!
We observed a total of about 100 hammerheads ![]()


And some of them even put on a show for us, making the revenge a great success!!
Wow, it was so powerful and fun!!! ![]()
Next time, I want to see a hammerhead river right in front of me!!!
Despite the wind not being on our side, the sea of Yonaguni was super hot like this!!

I want to dive again. It's a fickle sea, but it has romance.
That's how the sea of Yonaguni made me feel!!
I thought about talking about the land part as well, but it would get too long, so I'll end it here for today!!
Tomorrow, I'll talk about the land ![]()
So everyone, look forward to tomorrow's blog!!! ![]()
