Culture Studies 251 Preface After secondary school, I wanted to travel around the world, and then I wanted to study Japanese. This despite the fact that my father used to argue that he wanted his daughters to be the CEO of a bank one day (chances were very small that I would become one, after studying a language…) and without proper reason, apart from the fact that I found the Japanese written language extremely interesting. This interest in foreign languages and writing systems and the influence of knowing specific languages and being used to specific writing systems has, in addition to my wish to work as a kindergarten teacher one day, with 24 toddlers and a flute, probably been the reason why I have enjoyed doing research for my PhD and writing this thesis so much.
