Therefore to verify it was to appear in the footsteps of the historical act. In addition, there is a story modification should not reveal the truth of history know. In the other side there were case which analogize the those circumstance via investigation on the food situation in the time of Japanese colony. In that cases were such like only visiting to the region and listening aspects of the diet and wrote the reports from the usually elder. The error of those report including errors and preponderance of information or remember things is that they believes. This report were a parts of writing achievement made 󰡔farming and farmers of the Korean󰡕carriers of the in spite of a small portion, of the korea at the foodway and meals aimed to introduce the results of the investigation by Takaha-shinoboru who was Japanese scholars to uncover the truth in Korea 26 years(1918-1945) for a number of carriers. Especially, those investigation were passion, fund and more valuable and personal in his personal conviction This result’s summary are following as; The first, Jeollado, Gyeongsangdo, Chungcheongdo, Gyeonggido, Hwanghaedo were major production of rice in Korea. Even though there were between quantitative difference and the percentage of mixed diets, it was investigated the high frequency of eating rice in JeolladoㆍGyeongsangdoㆍGyeonggido. However, the percentage of eating rice showed the half in Hwanghaedo. Moreover, the percentage of eating rice showed very low in spite of the minimum site in Chungcheongdo. The second, the case of mixed diets was rice and barley in Jeollado, Gyeongsangdo, Gyeonggido. However, it was barley and vegetables in Chungcheongdo also it was mixed diets of the corn, millet, barnyard millet, red-bean or potatoes in Gangwon-do. The mixed diets was millet and red-bean, rice, cooked flour in Hwanghaedo. It was a very similar mixed diets type between Pyeongando and Hwanghaedo but Pyeongando was a high mixed grains such as bean, millet, buckwheat and african millet, mixed of corn and red beans, or potatoes and sweet potatoes. They rarely ate a rice while they ate a lots of mixed grains such like millet, barnyard millet, red-bean, bean or potatoes, oats, kidney beans and peas. In addition, the survey was showed that Jeju Island where had been included the administrative section in Jeollado was not only a high rate of mixed diets with barley, millet, buckwheat and beans. potatoes, sweet potatoes, but also there was used to be eating lots of wild vegetables. The third, the red bean was the best grain to mix the rice throughout the country. Otherwise, the bean was used with bean-curd and bean sprouts. In Bukseon, they mixed often ate kidney beans, peas with rice, or barnyard millet(potato, sweet potatoes), buckwheat and mung beans and wheat i.e. flour was mainly used for lunch or a secondary meal. The fourth, Hwanghaedo have not got only a wide range of especially delicious side dish, food for a guest, seasonal foods long time ago but also is very famous for their own foods. There were several reasons, Hwanghaedo was the best agricultural city, and there had producted the highest agricultural products(rice, barley, vegetable, fruits, etc.) and the most varied it at that time. The fifth, the food of the Inn was very difference in every area. Although, output characteristics of each region reflects food, mixed red-bean or sweet potato dish does not serve it such as vegetable and flour in anywhere. The sixth, as the case of Hwanghaedo, there was a variety of normal side dishes for breakfast and it was considerate of lifting a burden from lunch via light meal. In addition, It is customary for Hwanghaedo that they ate a plentiful foods for dinner. It means that they prefer quality to quantity. The seventh, according to local and seasonal factors, we believe that it has been developed the seasonal food much more diverse. Moreover, the results of the investigation was extremely limited in food resources at the time, therefore the seasonal food was the lack of local or seasonal variations as between meals for appeasing the hunger.
