January 3, 2017 — One hot evening last July, I visited the Michelin-starred unagi, or eel, restaurant Nodaiwa, which sits in a quiet basement beneath Tokyo’s glamorous Ginza shopping district. Next door is the world’s most famous sushi restaurant, Sukiyabashi Jiro, which was the subject of a documentary from 2012 called “Jiro Dreams of Sushi.” The restaurant is now so famous that a sign, written in English, sits outside its entrance, asking visitors not to take photographs.
In recent years, less benign developments have forced Nodaiwa to place a sign at its entrance as well. Whenever I visit, I count myself lucky to find the following message written on it, in Japanese: “Today we have natural Japanese eel.”
The restaurant started serving grilled eel out of a timber farmhouse, near the famous Tsukiji Fish Market, about two hundred years ago. And through five generations of continuous operation such a sign was unnecessary, even laughable, given the abundance of Japan’s native species of freshwater eel. But, in 2013, Japan’s government added Anguilla japonica to its official Red List of endangered fish, after researchers found that wild unagi populations had declined by about ninety per cent in the course of just three decades.
At Tsukiji, wholesale prices for farm-raised unagi imported from China immediately surged to a record high of around forty U.S. dollars per kilogram, and remained there for much of 2013. Prices for the wild-caught, “natural Japanese” eels served at upscale restaurants like Nodaiwa climbed even higher, by as much as fifty or sixty per cent.
But the government had been late to recognize the extent of the problem, which had already taken a toll on many famous restaurants specializing in kabayaki, a signature unagi preparation. In March, 2012, a year before the species was declared endangered, the beloved unagi restaurant Suekawa closed its doors, after sixty-five years of business, and it was followed a month later by the popular restaurant Yoshikawa. Then, in May of 2012, one of Japan’s best-loved kabayakirestaurants, called Benkei, closed its doors after more than six decades of serving eel in Tokyo’s historic “lower city.” The restaurants that survived were buying eels for ten times the price that they’d paid just eight years earlier, according to one vender at Tsukiji Fish Market. The family restaurant chain Hanaya decided to pull eel dishes from its summer menu.
