Abstract
The finger temperature responses to local cooling were examined on 8 groups of Japanese subjects and one group of Ainu in Hokkaido. The responses were low in Japanese subjects born on the main island in comparison with the values of subjects born on Hokkaido. The responses of Ainu were not greatly different from those of Japanese farmers in Huren, fish factory workers in Monbetsu and male students in Sapporo, but significantly higher than the responses of policemen, nurses and girl students in Asahikawa and fishermen in Monbets
Summarized results indicated that the responses of subjects in Hokkaido, particularly of Ainu, were considerably higher than the average values reported previously on Japanese subjects.
