Checked Shellfish Hunting Map in Japan?

In Japan, from spring to summer, many family goes to Shellfish hunting. Shellfish hunting is a Japanese family leisure time activity. I used to go when I was a kid. Do you go shellfish hunting in your country? I didn't notice until now, but I think this is a Japanese culture.

Best time to go shellfish hunting is spring, because tide goes on the further ebb. The best season differs on the places you go, so check on this shellfish hunting map in Japan.
What kind of shellfish can you get. Of course it differs on the places you go, but here are the example


Asari


Kagamigai


Shiofuki


Bakagai


Hamaguri


Mategai
This shellfish, Mategai is little bit different from the other. In order to get, first you but salt in its hole, then wait until it come out, and pull it out.
Here is a video from You Tube of Mategai Hunting.





Seems like Mategai is called Razor clam in english. Video of Razor clam oversea. It is much bigger than Japanese.
