My six-month Canon fellowship at the University of Tokyo was a tremendous experience. I learnt a lot about the Japanese legal environment, the structure of Japanese business organisations, and Japanese culture. During my stay in Japan I had numerous opportunities to exchange ideas with leading academics and practitioners (government officials, regulators, lawyers, and businessmen). This enabled me to appreciate the ‘law in action’. Japanese institutions have the most advanced research capacities and provide data sources in various forms. Working with academic, professional, and industrial institutions in Japan was vital not only to conducting comparative and empirical studies but also to appreciating the innovative methodologies Japanese institutions have adopted, often taking the lead in their specific field. Japan is an excellent country where to conduct collaborative research because of its liberal research environment, the wealth of research sources, the high calibre and rigour of its academia, and open access to critical data. These qualities together with Japanese academic institutions' willingness to forge lasting partnerships mean that research projects in Japan may often become sustainable in the long-term.
