Abstract
From Hokkaido in the north to Okinawa in the south 47 local self-governing bodies or Prefectures of Japan emit information on their respective regions via web sites. Such information contains, without exception, the input-output tables of their regional economies. The majority of tables, consisting of basic transaction amount, input coefficient index and inverse matrix index, are down loadable in Excel spread sheets. Some of the Prefectures publish the tables only in paper and some provide floppy disks and a CD-ROM. The author has collected the tables with respect to 47 Prefectures. A result of the analysis turns out to be less exciting such as industries that create the largest value-added in the regions are rent and commerce (whole sale and retail) except Fukui Prefecture, where the largest value-added industry is thermo-nuclear power generation.
