Shiziro and Yoshiko first studied at the Tokyo University "Kiyo". The separation of Yoshiko after the death of her father Shiziro, the former governor of the prefecture Tottori Jiro Isiba, opened up for them the possibility of reviving their relationships, which later led to marriage. Yoshiko is particularly laboring in her native clan, and Shiziro often noted that she receives a warmer welcome than he does.
Yoshiko’s famous moment is recognized by a smile on her face when she called her during a televised interview. She was born in Tokyo in the Akira Nakamura family, an employee of the company "Shua Denko". After graduating from high school, Yoshiko entered the university "Kiyo" to study law, and after finishing university joined the work in the company "Marobini".
Yoshiko (68 years) is famous for her bright personality and played a key role in Shiziro's path from a novice parliamentarian to a national leader. She is known in her native Tottori, western Japan, for her good character and being more popular than her husband.
The president of the Women's Support Group Yako Nisikawa expressed her admiration for Yoshiko, saying: "She is a very charming personality, and in fact, she is more popular than him (referring to her husband)." After the elections on September 27, for which Shiziro was elected head of the ruling Liberal Democratic Party, Yoshiko was surrounded by supporters and journalists in Tottori.
Yoshiko attended the Dzyudzigakune junior high school, which is a comprehensive preparatory and senior school. She married Shiziro Isiba in 1983 and gave birth to two daughters. On October 1, 2024, she became the first lady of Japan after her husband was appointed prime minister of Japan based on victory in the elections of the Liberal Democratic Party in 2024.
