Robson starts his Japanese adventure with an early morning visit to Tokyo’s famous Tsukiji market – the largest fish market in the world. Ten per cent of all the fish caught across the globe pass through this vast emporium, which takes millions of pounds every day. Some 400 different types of seafood are sold here – amongst them the highly poisonous fugu, or blowfish. “It says a lot about the Japanese that their favourite delicacy is a fish that could send you six feet under,” reflects Robson. “And they’ll pay up to a hundred quid for the pleasure!”
