As the Ogasawara islands are located in the subtropics, many kinds of vegetables can be cultivated there in open fields, even in winter. However, although young soybeans have also been introduced as a winter vegetable, growth and yields have been poor. Five experiments were carried out to identify the causes of problems and to measure the efficacy of techniques to improve growth and yields. In conclusion, nursery illumination enabled young soybeans to be sown in mid-January and harvested at the end of April, thus advancing harvesting about 20 days with low cost
