Princess Yuriko became the sister-in-law of Japan's World War II-era Emperor Hirohito when she married his brother Prince Mikasa.

Princess Mikasa, the oldest member of the Japanese royal family, died at 101 after being hospitalized since March. Born Yuriko Takagi in 1923, she married Prince Takahito and had five children.

She married the brother of wartime Emperor Hirohito less than two months before Japan’s attack on Pearl Harbor in 1941.

Japanese Princess Yuriko has passed away at the age of 101 following a recent decline in her health, according to palace officials.

Her death reduces Japan’s rapidly dwindling imperial family to 16 people, and only 4 men, as the country faces questions about the future under a male-only succession law.
