On Mikomoto Island, as long as sea conditions are good, there is a good chance of encountering hammerhead sharks.
It used to be said that water temperature had a great influence on the rate of appearance of hammerhead sharks, but in the past few years, we have been able to encounter them all year round.
In winter, however, winds become stronger and boats are often unable to sail.
We recommend the months of June to October when the sea conditions are relatively stable.
When the Kuroshio Current, one of the largest warm currents is approaching Izu, the conditions are even better.
You may be able to see schools of hammerheads in even better conditions!
This card will be issued once a day when the guide in charge of you certifies that "you have indeed seen the hammerheads!" Even if you see a hammer many times in a day, you will only get one card. No other sharks will be issued.
If you get a serial numbered Hammer Card, which is the only one in the world, you will be entered into a monthly drawing (June, July, August, September, October, and November) for a chance to win a gorgeous prize!
The winning serial number will be announced at the end of each month on our website.
You can look at the Kuroshio current information, but even if the Kuroshio seems to be far away from you, you may still be benefiting from the Kuroshio. This is shown by the fish of the southern region.
When southern fish such as yellowtail, muro-ji, kusayamoro, shira, and barracuda come in in schools, we can think, "This is a good chance for encountering hammerheads".
Mikomoto is home to an extraordinary array of fish. The hawksbills on the down tide and the chicken grouper on the up tide are often compared by the guides to a "wall" or "cloud" of fish. The schools of wrasses can be as large as 100 to 200, or even 500 or more, and they surround the divers, creating a tornado.
Other fish that attract mikomoto divers include schools of white sharks, schools of amberjack, schools of longtail snappers, and schools of red snappers.
