Mihara underwent treatment for cervical cancer later in her life, and established a nursing home in March 2010 prior to her political debut.^[1]

Political career

Mihara ran in the House of Councillors election in July 2010 as a proportional candidate of the Liberal Democratic Party^[7] and won, campaigning on her experience with women's health issues.^[1] She first appeared in the Diet on 30 July 2010.^[8] She was elected to a seat representing the Kanagawa at-large district in the July 2016 election^[9] and the July 2022 election.^[10]

Controversies

Mihara is in favor of visits to the controversial Yasukuni Shrine.^[12]

In March 2015, when speaking about dealing with tax evasion she urged Prime Minister Shinzō Abe to promote hakkō ichiu, a slogan meaning "the world under one roof".^[13][14] Although it is controversial as it was used during the WW2 for patriotism, she explained it as "an ethic which Japan has valued since its genesis".^[15]

HPV vaccine

Junko Mihara, a member of the House of Councillors and herself a cervical cancer survivor, became a vocal advocate for resuming proactive HPV vaccination. Although Mihara was never vaccinated herself, her personal experience with cervical cancer—including undergoing a hysterectomy—motivated her to campaign for broader access to the vaccine and stronger government support for inoculation programs. In public statements and interviews, she emphasized the urgency of protecting young women and expressed frustration over the years lost to misinformation and policy hesitation. Mihara described her advocacy as part of a broader fight against cancer, drawing on her own suffering to push for systemic change.^{[16][17][18][19]}
