Japan is big on its New Year's rituals (the first visit to the shrine, remembering one's first dream…) and one of the biggest firsts is the Tsukiji market tuna auction, which was held on Tuesday.

Having an auspicious start to the year is important, so, if you're the owner of a big sushi restaurant, starting 2016 with a prized fish is a good way to set up the next 12 months.

An auspicious first bite.

Restaurateur Kiyoshi Kimura, who has prevailed in most of the recent new year auctions, shelled out over $165,000 (about ¥14 million) for a 200-kilogram bluefin tuna on the first trading day of the new year.

In 2013, a bidding war drove Kimura's winning bid to ¥154.4 million (which amounts to about $1.4 million at today's exchange rate) for a 222-kilogram fish.

Tuna, as fresh as it gets.

80-year-old market is moving before the 2020 Olympics.

While the tradition of auctioning a big catch isn't likely to change, the location of the auction will. Next year, if all goes as planned, the world's biggest and most famous fish market is due to move into a massive new complex further south in Tokyo Bay.

Tsukiji's move signals the end of an era for some.

The closure of the Tsukiji market will punctuate the end of the post-war era for many of the mom-and-pop shops just outside the main market that peddle a cornucopia of sea-related products, from dried squid and seaweed to whale bacon and caviar.

Market move slowed by serious snag.

Planning for the move began nearly 20 years ago but the shift was delayed for years due to contamination in the soil at the new location, the former site of a coal gasification plant run by Tokyo Gas.

The city announced in 2001 that the market would be moved by 2012. But cleanup work dragged on, and in 2013, Tokyo Gas disclosed it had found more contamination.

Bluefin stocks falling. 

Japanese eat about 80 per cent of all bluefin tuna caught worldwide, and stocks of all three bluefin species — the Pacific, Southern and Atlantic — have fallen over the past 15 years amid overfishing.
