The new theory has been strongly supported generally for its clear logic; however, in terms of art history, they are taking a drawing style which is seen in the late Heian period to the early Kamakura period, that could not be a drawing in the period of Northern and Southern Courts, and it is repeatedly claimed that there is no positive evidence to consider that these three portraits were done in the period of Northern and Southern Courts; there has been a significant gap between these theories and the controversy has not yet been concluded.
一般的には、論理の明解さから新説を支持する意見が多いとされるが、美術史の立場からは、三像の画風が平安後期-鎌倉初期のものであり、様式から見て南北朝期のものとは言い難く、三像の成立を南北朝期まで下らせる積極的理由のないことが繰り返し強調されるなど、両者間の断絶は大きく、論争の終結はまだ見込まれていない。
