So, I like to join it.

Then, As for underwater, the visibility is getting better than yesterday.
The surface area is still white, but the bottom area is clear.

Today, I could find out rare shrimp.

Periclimenaeus gorgonidarum SP.
We can see it one or two times in a year.
So, I’m so happy when I can find out it.

In spring season, there are so many sea weeds.
Some sea slug live on the sea weed.

The form is so cute. I like this sea slug!!
The size is 1mm haha
It is hard to see it with your eyes only. Do you wanna see tiny underwater creatures?

Others, there are many kinds of macro creatures in bay side area.

We will be closed for 4 days starting tomorrow.
So, I go back to my parents house.

I hope the visibility is getting better at Friday.
See you then(^^)/

I think so!!! Kushimoto area has various of underwater creatures.

I introduced many kind of underwater creatures unique to Japan.

First of all, I could find “Japanese pigmy sea hourse”.
I usually want every foreigner divers to see it!!

The size is so tiny!!!
It is hard to take a pic of that. But, it can be seen in japan only.

And that fish lives in Japan’s sea only.
That name is “Japanese pigmy angel fish”.

The body color is so beautiful!!!
When you dive in Japan, you should see it, I guess.

We did three dives in a day!!

There are many Chicken Grunt in dive point today.

June 9, 2023

Weather: Cloudy
Ground Temperature: 22~24℃
Water Temperature: 21~22℃
Wind Direction: Southwest(4~6m/s)
Swell: 1.0~1.5m

It was heavy rain yesterday.
So, I think today’s visibility is getting worse before going to first dive.

But, when I enter the sea, it is better than expected.
After getting to the bottom, there are many small fishes near a anchor line.

It is called “Kinme-modoki” in Japanese. And English name is Pigmy sweeper.
The beauty of the shapes made by fish is indescribable.

Recently, there are many Chicken grunt in Bayside dive point.

Sometimes, some  Big Grouper attacked them.

At that time, the Chicken Grunt gather to drive away the Grouper.
The scene is very powerful,I think.

At the bottom area, many kinds of fishes are spawning or protecting their eggs.
Most of fish breed from now until around August.

If you come to Kushimoto at that time, you can see the behavior of fish breeding or spawning.
This Swatail blenny is protecting eggs in a hole.

In the fish world, it is common for father fishes to take care of eggs and baby.

The water temperature  is getting warmer.
From now until October is the best season for diving.

I will enjoy diving tomorrow as well.

See you then(^^)/

I went to diving to investigate of coral egg growth in this morning.
Some coral egg is growing steadily.

If the water temperature is getting warmer, we could observe coral spawning  in this month.

In Kushimoto, there are many coral reef in beach diving point.
The coral reef is protected by Ramsar Convention.

The coral reef is northernmost place in the world.
So, I want everyone to see this sight.

Then, If you’re lucky, you can observe coral spawning.
It seems like a starry sky.

It’s so beautiful.
If you want to see it, you need to have a night dive experience.
But, I want you to see it!!

The coral spawning can be observed through June to July.
Some coral will be spawning at August.

I try to do research dive for coral spawning as much as possible .

I could observe coral spawning three years in a row.
So, I wanna observe this scene this year as well.

At last, I will show you the movie of the dive point.
The coral is very beautiful.

I’m looking forward everyone to  come and visit us.
