1) Table 1: Annual Transition of the Total Production of Japanese Akoya Pearls

This table is the transition of annual production beyond 1946. The production for 10 years since 1983 had been stable at 18,000 – 19,000 Kan a year. However for the past 5 years, the yearly output sharply decreased due to the exceptionally high morality. Poisonous Formalin and virus were given as reasons, but the effects of a long period of overcrowded oyster beds which caused deterioration of the farming ground may have been a more important reason.

3) Table 3: South Sea Pearls Exported from Japan

Japan imported about 500 Kan (74% of the total production), and 80% (400 Kan) of this has been re-exported from Japan. The total re-export increased to 2 times within these 4 years.

5) Table 6: Exports of Black Pearls from Tahiti

Japan is still a distant leader as a buyer but the proportion has decreased these recent years. The proportion of exports to U.S.A. and Hong Kong has rapidly increased; the demand in the USA. is especially outstanding. The demand for gray pearls would increase in USA if promoted properly.

This is a combined statistic of exports reported by Tahiti and imports by Japan In the past, the figures did not match, but recently accuracy has improved.
