Overview of Ito

Let hundreds of sharks surround you in Chiba!
Ito, situated at the tip of Boso Peninsula in Chiba prefecture, is in the west of Tokyo bay, only about 2 hours away from Tokyo by car.
This might be the only place in the world where you can see so many sharks this close by.

The story leads back to the concern of fishermen in Ito.
There were originally many banded houndsharks in this area. The problem was: they were getting into the net and eating the fish captured by fixed-net fishing.
The fishermen asked for help, so Kan Shiota of ITO Diving Service BOMMIE decided to lead the sharks away from the nets by feeding them elsewhere. This was in 2009.
This strategy succeeded in attracting many banded houndsharks and red stingray, and the feeding place have become a fascinating dive site now known as "Shark City".

The 4 main creatures in Ito are red stingray, bulgyhead wrasse, longtooth grouper, and banded houndsharks.
Listed below are how they are called in Japanese.
・Red stingray=Akaei
・Bulgyhead wrasse=Kobudai
・Longtooth grouper=Kue
・Banded houndfish=Dochizame

Taking the first letter of each creature's Japanese name, they are called "AKKD480". This name comes from the famous Japanese idol "AKB48".
"AKKD480" is the idol of Ito♥

!Caution at the "Shark City"!

The banded houndsharks are usually very calm.
However, when feeding, they sometimes bump into you, making your mask and regulator come off.
Listed below are the things you need to be careful about.

★Make sure to have your hood & gloves on.

★Mask clearing and regulator recovery are must-have skills.

★Do not chase the sharks and stingray.

★The depth is over 20 m, and the current is sometimes strong, so you need skills above intermediate level.

Do not panic when the sharks bump into you!

During winter, it is exciting to watch Japanese cormorant dive into the ocean in search of prey. There are not many dive sites where you can enjoy birdwatching underwater!
