It’s painful get up at 5am and make the trek to Tsukiji Fish Market before work. Strange as it might seem, if there’s one thing you have to see, it’s this. It’s the largest wholesale fish market in the world, and handles more than 400 different types of seafood from tiny sardines to 300kg tuna. Watching the gigantic fish prepared for sale or the auctioneers’ enthusiasm at landing their prize is a fabulous way to start the day. A tip: make sure you eat breakfast at the market before you leave.
