1921 (Taisho 10) Thursday, April 21 It is reported that the health of Aritomo Yamagata is better than in recent years, he drinks wine with his own hands and has a good appetite. “From the ordinary to the clear mind is more clear.” he said. However, Yamagata, who was devastated by the certain serious incident of the Imperial Court, confined himself at Kokian in Odawara and gave up his annual visit to Murinan in Kyoto. He fell ill from autumn of the same year and died on February 1 of the following year.
According to the latest research by Dr. Yukio Ito, Yamagata, who is at the top of the military, was seriously concerned about the possibility that future marshals would become color-blind, a factor that led to the defeat of the military academy. According to Dr. Gen Mizoguchi, the possibility of color blindness was also high from the viewpoint of modern medicine.
