In fact, both of them made important contributions to the country and nation. However, both of them were misunderstood and belittled even in modern times. Due to the influence of corruption and backwardness at the end of the Tokugawa period, modern Japanese have a derogatory attitude towards Tokugawa Ieyasu, and even commenting on people like Tokugawa Ieyasu is an insult to him. This situation also reflects the modern Japanese nation's neglect of the virtues of humility, patience, and kindness advocated by Tokugawa Ieyasu. It is an important manifestation of Japan's ideological deviation toward militarism, arrogance, cruelty, and impatience. It is also the main factor in Japan's defeat in World War II.

However, modern China's evaluation and understanding of Sima Yi is far less objective than Japan's understanding of Tokugawa Ieyasu. This is probably the reason why China still has not unified its thinking.
