Japan is divided into 9 regions, which are split into 47 smaller prefectures. Those regions are not formally specified; they do not have elected officials nor are they corporate bodies. However, the practice of ordering prefectures based on their geographic region is traditional. They are numbered based on their location from north to south.
The following pages contain a presentation for each prefecture providing a general overview about their economy (local industries specialisation, opportunities, available incentives and support for EU companies...), advancement of local research and science, local culture, geography, landscape and environment.
