Puffer fish is called fugu in Japan.
河豚/fugu is made up of the characters for “river” and “pig”. Mmm.
It is often served raw in thin slices.
Fugu is a dangerous dish and people preparing it have to go through training.
A neural toxin, called tetrodotoxin, is contained within the internal organs of a puffer fish and it can cause muscle paralysis and lead to respiratory standstill.
Fugu is best eaten in winter when the fish are fattened up for the cerold weath… but it’s also the most expensive!
Fugu can range from 2000 yen a plate to over 20,000 yen.
If you’re interested there’s a whole wiki page dedicated to fugu.
