Diving Destination Chiba Prefecture Day-tripping in Tokyo's backyard

About Chiba

Chiba is blessed with an attractive coastline that in the summer sees Tokyoites arriving in droves to enjoy the wide sandy beaches, high-quality surf and laid-back atmosphere on offer. July and August is when the beaches and surrounding towns really come alive. Bars, restaurants, shops and marine activities become widely available for the weekend urban crowds. The most popular beaches are Onjuku, Nakazato and Kujukuri-hama, though there’s plenty of room for exploration along Chiba’s 500-plus kilometer coastline a surfers paradise.
It is also a popular destination for Tokyo divers. One reason being that it has easy access from Tokyo and also Yokohama area using the Tokyo Bay Aqua tunnel running below the Tokyo Bay. The diving spots mainly are located at the tip of the Chiba peninsula, and located of the pacific side. Here, the warm Black current and the cold current for the south collide of the coast, giving this region a mix of tropical and cold water marine life.
Chiba Prefecture is where we have the Narita Airport. From Narita airport, the diving spots are much closer than Tokyo.

Chiba Ito 

Japanese Hound Shark heaven

Ito Tateyama Chiba "Shark Scramble" is one of the hottest topics for the Japan region diving scene for some time.
It is the work of Mr. Kan Shiota, the Diving Shop owner of "Bommie" (Which is the only resort Diving shop for this Diving spot) who received a request for the local fisherman to solve the shark issue which the fisherman was facing at the time.

The local fisherman didn't want the sharks to be caught in the nets as they were damaging the fishes they want to send to the market. Mr. Shiota says that the sharks that was caught was also being damaged as they were thrown back to the ocean. To solve this issue, Mr. Shiota set out to lure the sharks away from the fishing nets.
With the shark population stable, and presumably happy, we are very lucky to have this wonderful diving spot just a few hours away from Tokyo.

To dive at Ito, you can either use the only resort diving shop "Bommie" or searched for City diving shops near you and join their excursion trip out to Ito.
