KONSEN-GENYA, the eastern part of Hokkaido, extended from Nemuro Province to Kushiro Province, is often called an undeveloped treasury and thedevelopment is being keenly watched by the public from the present circumstances of Japan. The fundamental problem of the cultivation is the hygienic condition of people who come to cultivate as novices. For the purpose, it is necessary to investigate the life of people who have started reclamation in this area. These results are as follows : 1. Most of them had been people inexperienced of dairy farming before thiscultivation and we ought to expect the same from further recruits yet to join. 2. It is noticeable that the immigrants have infants or babies handicapping their activity, when they are inevitably hard workers. 3. The first stage of the labour for finishing 50% of cultivation generally takes 3 or 4 years. 4. If their method of cultivation sould be continued, it is necessary to give them some facility for recreation, because their labour of the first stage are very hard, 5. It is desirable that a radio etc. may be used as important means of the education for them. 6. The investigation about their housing, nutrition and children were also carried out. 7. In the centre of the problem, there is food problem, egh how to powder the grain and to preserve it and other food material for winter. This will bedealt with in a separate report, which will soon follow.
