I used to eat fresh sea urchin (as in eaten right after getting it through diving) every time I visited my hometown since we live beside the beach. Usually it's hard to find sashimi cuisines like salmon and tuna since they're only common in selective places. Even in my area where there's many beaches and bodies of water, you'd rarely see places offering these.
So you're best bet is to head to a country that does, like Japan, if you can't find any local supply.
I really want to try fresh FRESH sashimi of any kind, tuna, salmon, octopus, wtv. But I don't live near the ocean, and my country don't really eat raw food so no one really prepare them fresh, even in sea villages.
