KESEN-NUMA CITY, JAPAN - It's 5am on the the north eastern tip of Japan's main island of Honshu, and 75 tons of dead shark is being meticulously arranged into a neat grid of tidy piles, of twenty sharks per pile. If you thought shark finning was exclusively a Chinese problem, think again. Welcome to Kesen-numa City, Japan's shark fin capital. Here, six days a week, small teams of Japanese workers go about the hushed business of industrial shark-finning. By 6.30am, with piles arranged, the sharks are disemboweled first. Hearts are ripped efficiently from their bodies by men wearing brightly coloured rubber boots and aprons. At 7am, the shark corpses are cleaned of their blood by workers wielding water hoses. And by 8am, small teams are silently moving up and down aisles and rows like robots in a Japanese car factory, quickly slicing off every dorsal, pectoral and tail fin from the lifeless, grey lumps. Big hungry black crows squawk in the shadows, looking for bloody morsels. And shark fins plop with regularity into small yellow plastic baskets. The baskets fill up fast, are then weighed, and finally carried to a nearby truck, where a man with a notepad strikes a deal. At 9.30am, it's all over for another day. Fork lift trucks scoop up tons of limbless carcasses, then dump them into a high-sided truck. The process is a brutal sight to behold, and not for the faint-hearted. The fishing port of Kesen-numa City is located in Miyagi Prefecture in North East Japan, and is the country's only port dedicated to catching sharks. Over two days in early July 2010, I saw 119 tons of blue shark (Prionace glaucaof), ten tons of salmon shark (Lamna ditropis), and three tons of short fin mako shark (Isurus oxyrinchus) landed on the dock at Kesen-numa. Not to mention several tons of endangered bluefin tuna, (Thunnus thynnus), but that's a whole other story. Taking government transparency to another level, landed shark tonnage numbers are provided daily by the port of Kesen-numa's Japanese only website, which is publicly, (and apparently unashamedly), available. According to the most recent data available, a Kesen-numa Municipal Fisheries report, the gross tonnage of blue sharks landed in the small fishing port dropped from 9,722 tons in 2007 to 8,200 tons in 2008, a decline of 18.6%. Only a small portion of shark fin prepared in Kesen-numa is destined for export, mostly to Hong Kong and Shanghai, where Japanese shark fin is seen as a premium brand by the new wealthy elite of China. For wealthy Chinese, shark fin from Kesen-numa is seen as a premium, or luxury, brand. Mr Hatakeyama, 45, a shark fin processor from Kesen-numa, said, "Quite a bit of shark fin is sent to Shanghai from here as there are many rich people there. Our shark fin here can command higher prices than Chinese shark fin sourced from elsewhere in Asia, the Middle East or Africa. Even though the Chinese have their own shark fin, they prefer Japanese brands". Given the delicacy's roots, this is hardly surprising, but what is more unexpected is that the majority of shark fin processed in Kesen-numa is for domestic consumption as shark fin soup at Chinese restaurants and expensive hotels in Japan. Like in China, shark fin soup is common place at weddings, company banquets and all sorts of other special occasions where the paying host wants to show off their wealth. And much of the shark fin produced at small food factories dotted around the city ends up bound for Chinese restaurants in Japan, of which there are many. The rest is sold to hotels to include on their menus for newly weds and for corporate banquets. In olden times, shark fin was sometimes used as a substitute for gold when Japanese merchants traded with China. Understandably, and for this same reason, the exact location for fin drying in Japan remains a closely guarded secret. And a significant amount is shipped to China for sun-drying, although the exact drying location in China is an even bigger secret. These days, the port of Kesen-numa feels like a town down on it's luck. Once thriving, today there is a sense of decay in the air. Overgrown and rusty. Similarly, attitudes have yet to move with the times. As public sentiment slowly turns against shark fin soup in Hong Kong, what was once an ancient tradition in this forgotten corner of Japan, is, according to conservationists, wreaking havoc on shark populations worldwide. Small fishing boats used catch sharks as part of the city's ancient tradition. But this tradition, coupled with modern fishing methods like the advent of strong and long fishing lines, and boats that can go further and stay out of port for longer, is a recipe for disaster for the sharks. According to the Japan Fisheries Agency, the nation's national shark fin catch nearly halved since the late 1960's. In 1969, the total number of sharks caught and landed in Japan was around 65,000 tons. Last year's total was around 35,000 tons, and Kesen-numa accounts for around 90% of
