Singaporean guest came to our shop today!!
It’s first time to dive in Japan.

So, I showed him various of underwater creatures today.
This angel fish lives in the coast around Honshu.

The color is beautiful!! So, It is expensive fish as aquarium.
But, don’t catch it….haha

And I introduce tiny sea sulg.
When I dive with overseas tourists, I always introduce it.

The color is similar to Pokemon Pikachu, isn’t it??

And, the number of this fish is increasing  recently.

This fishes is famous fish in Kushimoto.

I went to diving for searching tiny nudibranchs today.
At first dive, the guest wanna see tiny Pikachu nudibranch, so I went to the dive point which can see it.

The color seems like Pokemon Pikachu. So we call it “Pikachu”.
The size is 2mm. It’s so tiny!!!

There are many Pikachu recently. If you wanna see it, you can see easily in this season.

At second dives, I saw these tiny nudibranchs.

These size is also 2mm~3mm.
In witer season, Some Japanese diver like searching for tiny underwatar creatures.

Of course, there are various of underwater creatures expected nudibranchs.
If you like see macro creatures, I recommend you to dive in this season.

And if you like Nudibranch, Now is the best season to see them.

The Kushimoto’s sea has very big waves and strong winds.
So, we cannot dive in Kushimoto area.

I went to other diving site which is called “Uchiura beach”.
It is first time to dive in this season.

There are usually many fishes in this point.

And there are also many kinds of macro creatures.


I could find out Pikachu sea slug.
I kept searching this sea slug for a month.

Finally, I can find it!!!
When I find it, I feel so happy!!!

And I met Lion fish that has beautiful fin!!
This fin is so beautiful, isn’t it??

At last dive, I met cattle fish.
When it feel stress or getting angry, its color change to beautiful color.

In winter season, the day which we cannot dive in Kushimoto area due to strong wind is getting more.

So, I think the time that going to Uchiura is more and more.
This point is so fun for diving.

Our dive site has so many diving point.
So, you can see various situations if you come to here.

Please come and visit us!!

See you then(^^)/
