This is the most expensive fish in Japan.

In January 2018, a kilogram of these baby eels cost around $35,000.

That's more than bluefin tuna, and almost as much as the price of gold at the time.

But catching these eels is just the beginning.

It can take a year of work until they're large enough to be sold.

People in Japan have eaten eel for thousands of years.

Restaurants like this can sell 40 to 50 tons of eel each year.

Japanese eel, or Anguilla japonica, can be found across East Asia, but overfishing and changing habitats have caused a huge decline in eel populations.

Since 1980, the global catch of eel has declined by more than 75%, which has had a huge effect on price.

Unlike other types of fishing, the majority of eels are raised, not caught as adults.

Young eels, called glass eels, are caught in the wild and raised on farms like this.

No farms have been able to efficiently breed the eels in captivity.

So farmers depend on the catch of young eels to make a profit.

Raising this many eels requires constant attention.

Michio has been working as an eel farmer for almost 40 years.

After the cost of the eels themselves, feeding them is the most expensive part.

Two to three times a day, workers feed eels this.

It's a mixture of fish meal, wheat, soybean meal, and fish oil.

After six to 12 months of work, eels are big enough to be sold.

Workers unload the eels and sort them by size to determine where they'll be sold.

Experienced workers can quickly tell the difference just by feel.

Some of these eels will end up at restaurants like Surugaya, which has been serving eel for over 150 years.

That high demand is part of the reason young eels are so expensive.

It may look simple, but preparing it takes years to master.

Workers prepare eel alive to maintain freshness, but this makes handling much more difficult.

Workers remove the bones and cut eels to the proper size for the skewers.

Eel has to be constantly monitored while it's cooking to achieve even grilling.

Chefs steam then grill each eel three times, dipping it into sauce between each grilling.

Kabayaki presented in a lacquer box with rice is called "unajū".

It can cost up to $91 depending on the price of adult eel.

If prices are too high, restaurants struggle to make a profit.

In Japan, eels are eaten year-round, but consumption peaks in the summer, and it's become a big part of some local economies.

In 2014, Japanese eels were classified as endangered,

and because of low domestic catch, the majority of eels eaten in Japan are imported from China and Taiwan.

There have been efforts to improve the eel population,

like regulating fishing, releasing adult eels back into the water, and researching how to hatch eels in farms.

But the future of Japanese eels remains unclear, and the price is likely to increase with demand.
