Japanese fisheries are affected by a general decrease in the number and an aging of fishermen which reduces the vitality of the communities. However, the situation is not clear as there is no generally recognized indicator in Japan for the vitality of a fishing community.
 The general aims of this research were:
1. Construction and analysis of a fisheries vitality index
Therefore we extracted 16 indices from a fishery census and devised a "fisheries vitalityindex" to compare the fisheries vitality and the chronological order of changes for comparisonbetween areas and carried out a diagnosis of fisheries vitality.
2. Devise a diagnostic system of fisheries vitality
We devised a diagnostic system of fisheries vitality by using the "fisheries vitality index". Next using this system, we showed what is required to revive these fishing communities. And we inspected the adjustment between this system and the regional differences at the sample area.
