Abstract
The author made a check of the past five years' itinerary medical service to the islands scattered in the Inland Sea of Japan. All-inclusive, 15, 599 persons received such medical service, including more feinales than males. The diseases found inhigh frequencies were hypertension, neuralgia and diseases of digestive organs, as is also the case with the main land. The diseases found in higher frequencies than expected were anemia, hypotension and gastroptosis, which would have been caused from the peculiar working conditions handicapped by nature and from undernourishment.
