In 1960, a survey showed Japanese orphanage children to be shorter in stature than Japanese children in general. In 1964, food budgets for orphanages were increased and, on Hokkaido, 180 gm. milk per day was made available for each child. In 1968, a further improvement in the diet was made by providing for an egg a day for each child, plus more liberal money allowances. Data from surveys in 1965 and 1970 on food served to these children reflected the improvements, as compared with 1960, Figures on the stature of the orphanage children were also compared. By 1970, the only orphanage children falling below the national mean were the teen-age boys and, to a lesser extent, the adolescent girls. Weight differences in all three surveys were less striking.
1960年的一项调查显示，日本孤儿院儿童的身高比一般日本儿童矮。1964年，孤儿院的食品预算增加，在北海道，每个孩子每天可获得180克牛奶。1968年，通过为每个孩子每天提供一个鸡蛋以及增加零花钱，饮食进一步改善。1965年和1970年对这些儿童饮食情况的调查数据反映了与1960年相比的改善情况，同时也比较了孤儿院儿童的身高数据。到1970年，身高低于全国平均水平的孤儿院儿童只有十几岁的男孩，十几岁的女孩受影响程度较小。三次调查中的体重差异则不那么明显。
