Overview

Princess Chichibu (born Setsuko Matsudaira; 9 September 1909 – 25 August 1995) was the wife of Prince Chichibu, the second son of Emperor Taishō. As a member of the imperial household she was a sister‑in‑law of Emperor Shōwa and an aunt of the current Emperor, Akihito. She combined the private role of an imperial princess with a long public career in charitable, medical and cultural organisations in Japan and overseas.

Family background and role

Born into the Matsudaira family, a prominent lineage connected to samurai and court circles, Setsuko entered the imperial family by marriage and adopted duties typical for its women: representing the household at official events, supporting charity, and promoting cultural exchange. Her position gave her both social visibility and platforms for advocacy, particularly in health and international friendship.

Public service and health advocacy

After the death of her husband from tuberculosis in 1953, Princess Chichibu devoted considerable effort to public health causes. She became president of the Japanese Society for the Prevention of Tuberculosis and used her status to raise awareness, encourage research, and support patients and families affected by respiratory disease. Her leadership helped sustain attention on tuberculosis at a time when Japan was rebuilding its medical infrastructure.

International and cultural engagement

Princess Chichibu maintained active links with friends and organisations abroad and was widely seen as a figure of cultural diplomacy. She served in honorary roles that fostered bilateral ties and mutual understanding:

  • Honorary president of the Britain‑Japan Society (Japan–UK relations)
  • Honorary president of the Sweden‑Japan Society
  • Honorary vice‑president of the Japanese Red Cross

Legacy and notable facts

Princess Chichibu is remembered for bridging traditional imperial duties with active humanitarian work. Her efforts in combating tuberculosis and promoting international friendship left a lasting imprint on postwar civic life in Japan. She maintained long personal relationships with medical and service organisations worldwide and was frequently involved in public commemorations and charity events until late in life. Princess Chichibu died of heart failure on 25 August 1995.

Further context

Her life illustrates how members of the imperial household have taken on social causes as a form of soft power and public service. By lending royal patronage to health campaigns and cross‑cultural societies, she helped sustain non‑governmental ties that complemented official diplomacy.
