Fukunaga Kosei

Kosei Fukunaga (born Aisin-Gioro Husheng; March 13, 1940) is a woman of Manchu-Japanese heritage. She was born at Juntendo University Hospital in Tokyo, Japan. Her birth name was Aisin-Gioro Husheng, and her native name in Japanese is 福永 嫮生. She is a member of the Aisin Gioro clan, the imperial family of the Qing dynasty in China.

Her father was Pujie, a member of the Qing imperial family and the younger brother of the last Chinese Emperor Puyi (also known as Xuantong). Her mother was Hiro Saga, a Japanese noblewoman with distant familial ties to Emperor Shōwa. Husheng was the younger daughter in her family, with an elder sister named Huisheng, born in 1938 in Xinjing, Manchukuo.

In 1940, her family moved from Tokyo back to Xinjing, the capital of Manchukuo. Following Japan's surrender in World War II, amid the Soviet invasion of Manchuria in August 1945, her family was involved in a planned escape. Her uncle, Puyi, who was the last Emperor of China, arranged for other members of the imperial family—including Empress Wanrong and Li Yuqin, a former concubine—to evacuate to Korea via train. The group initially departed from Dalizi, where her mother, Hiro Saga, was entrusted with overseeing the imperial family members and was given antiques and funds to support their journey to Korea.

During this period, her father, uncle, and a servant, General Yoshioka Yasunori, along with a doctor, traveled separately to Tonghua and then to Mukden (now Shenyang), where they awaited a flight to Japan. Throughout this time, Husheng and her family faced multiple captures and relocations. They were detained by Soviet officers, moved to various locations including Linjiang, Changchun, Yanji, and Mudanjiang. Her grandmother Wanrong suffered from malnutrition and opium withdrawal and died in June 1946 in Mudanjiang. Following these events, Husheng and her mother Hiro Saga, along with other family members, were eventually released in July 1946 and repatriated to Japan by January 1947.

Upon returning to Japan, Husheng and her sister Huisheng lived with their maternal grandfather, Marquis Saneto Saga. They attended private schools, including Gakushūin in Tokyo. Huisheng died in 1957 in an apparent murder-suicide incident at Mount Amagi.

In 1960, her father, Pujie, was released from the Fushun War Criminals Management Centre after being pardoned by the Chinese government. He subsequently joined the Chinese Communist Party. In 1961, Husheng visited China with her mother to reunite with her father, who was then residing in Beijing. She returned to Japan and became a Japanese citizen through naturalization. She visited China again in 1963, staying with her parents for a year before returning to Japan.

In 1968, she married Kenji Fukunaga in Kobe, Hyōgo Prefecture, and adopted the name Kosei Fukunaga. The marriage produced five children: Masako Fukunaga, Tsuneaki Fukunaga, Yukiyoshi Fukunaga, Hironobu Fukunaga, and Noriko Fukunaga.

Later in life, Fukunaga has been active in promoting relations between China and Japan. She resides in Nishinomiya, Hyōgo Prefecture. In 2013, she donated letters and personal belongings of her deceased parents to Kwansei Gakuin University.
