Japanese Princess Yuriko, the oldest member of the imperial family and wife of wartime Emperor Hirohito’s brother, has died at the age of 101. Her health had recently deteriorated, and she passed away on Friday at a Tokyo hospital, according to palace officials. While the cause of death was not officially announced, Japanese media reported that she succumbed to pneumonia.
A Life of Nobility
Born in 1923 into an aristocratic family, Yuriko married Prince Mikasa—Hirohito’s younger brother and the uncle of the current Emperor Naruhito—at the age of 18, just months before World War II began.
War Memories
Yuriko shared her experiences of living in a shelter with her husband and their infant daughter after their home was destroyed during the U.S. firebombing of Tokyo in the war’s final months in 1945.
Family and Contributions
Throughout her life, Yuriko raised five children and supported Prince Mikasa’s research in ancient Near Eastern history. She fulfilled her official duties while also engaging in philanthropic work. She outlived her husband and all three of her sons.
Impact on the Imperial Family
With Yuriko’s passing, Japan’s imperial family now consists of just 16 members, including four men. This raises concerns about the future of the royal family, particularly as conservative factions within the ruling party advocate for a male-only line of succession. The 1947 Imperial House Law, which reflects traditional prewar values, permits only males to ascend the throne and strips female royals of their status upon marrying commoners.

Succession Challenges
Currently, the youngest male member of the imperial family, Prince Hisahito, is the sole heir apparent, presenting significant challenges for a system that does not allow for empresses. The government is actively discussing ways to ensure stable succession without relying on female members.
Yuriko’s Later Years
Before her health decline, Yuriko lived an active life as a centenarian. She enjoyed morning exercises while watching fitness programs and kept up with current events by reading various newspapers and magazines. She had a fondness for watching news and baseball on television and often spent time in the palace garden, either sitting outdoors or being wheeled in her wheelchair.
Final Health Struggles
Following a stroke and subsequent pneumonia in March, Yuriko had been hospitalized and had experienced several stays in intensive care. Her condition worsened over the past week, leading to her passing, as reported by the Imperial Household Agency.
