The clinical features and the characterishis of 678 patients with gastric anisakiasis found in Kagoshima prefecture from 1982 to 1987 were analysed in this paper. Immediately after taking a history of the present illness especially when taking raw fish, emergency endoscopy was performed on the all patients, and parasites were removed with biopsy forceps. Most of the patients complained of severe epigastralgia with or without nausea and vomiting. The interval between taking raw fish and onset of the complaints were 6 to 8 hours, and 83.4% of onset were within 12 hours. Concerning to the attributable fishes, mackerel accounted for 74%, and then sardine and horse mackerel for 13% and 8% respectively. As for the locations in which the parasites had penetrated, the greater curvature of the gastric body and angle showed the highest frequency with a degree of 37.4%. Two peaks were seen in the monthly incidence of the anisakiasis, the first was in February to May, and the second in September to October. All of 158 parasites which could be examined parasitologically were identified as anisakis larva Type I.
