To anyone wondering about the importance of the Japanese market, the shock of Tokyo’s constant flow of people will be an instant revelation. The city is home to 37m people who throng its busy streets day and night under towering neon lights. They commute through an even busier sprawling transport system, where they can buy hot and cold food and drinks from underground malls and ubiquitous vending machines – you can even pay for ice cream with your metro pass. Supermarkets, bars and restaurants extend vertically into high-rise buildings.The national population is 125m, but it peaked in 2010 and is now ageing rapidly. All observers of the Japanese food market are quick to warn of this risk: according to government forecasts, the population will shrink to 102m by 2045. The country has also suffered from years of economic stagnation caused by the global financial crisis and the 2011 tsunami and Fukushima nuclear accident. Yet, for many reasons, Japan remains an attractive export market and the proposed free trade agreement with the EU holds some promise for Irish farmers.
