One of the first things I learned during my year in Japan is that English does not always help. Of course, I had heard that foreign languages are not always spoken everywhere in Asia despite being taught but I had started learning some Japanese before I went so I thought it would not be a problem.
It was clear within the first few weeks that I was mistaken when there were only three people in total with whom I was able to communicate more or less successfully. One of these was half New Zealander and had grown up bilingual. As the months went by, I realised that many Japanese people do speak foreign languages but lack the confidence to use them at every available opportunity, unlike us proud Europeans. But that was no longer a problem after three months. You quickly get used to it and the lack of other options means that you soon learn to speak the language!
