Ito Tateyama Chiba "Shark Scramble" is one of the hottest topics for the Japan region diving scene for a few years. Kan the Diving Shop owner of "Bommie" (Which is the only resort Diving shop for this Diving spot) started this Diving shop after a request from the local fisherman to pull away the Japanese banded hound sharks which was damaging the fishing nets of this region.
From the conservation side of this request, and also Kan's dream to make the "one and only" diving spot in Japan, he started from scrach, feeding the sharks away from the fishing sites. It took him 5 years to make his deram come true.
Now the sharks, still in it's wild habitat, stays away from the fising nets, and are the center of attemtion from divers all around the globe.

*There are City resort diving shops visiting Bommie, so check your local diving shops.
