The visibility is better than expected

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.

Reservations will be filled up quickly in the future, so please contact us as soon as possible.

I’m looking forward everyone to  come and visit us.
See you then(^^)/
