What kind of scene do you imagine when you hear shark diving?        Were you watching the Great white shark, Carcharodon carcharias (Linnaeus, 1758), from inside the special cage offshore South Africa? Or diving with Blacktail reef shark (Carcharhinus amblyrhynchos (Bleeker, 1856)), or Blacktip reef shark (Carcharhinus melanopterus (Quoy & Gaimard, 1824)) in the colorful coral reef of Micronesia?  You can enjoy shark diving near Tokyo, Japan.    The exact place is Ito, Tateyama, Chiba, Japan. Ito is the name of a tiny fisherman port town located the most south of the Boso peninsula. It is similar to the later shark diving, though the different point is the location.    Enjoy the world-class underwater tunnel also      It is easy to get to the dive site to use the Aqualine route. The Aqualine is the Tokyo bay Crossing route that runs an undersea tunnel from Kawasaki, Kanagawa to Kisarazu, Chiba. Half of the course is the long bridge, and after half is the undersea tunnel. The artificial island "Umihotaru"…
