The Tokyo Metropolitan Police Department began its spring personnel changes on the 9th, which are set to affect approximately 1,700 officials including police officers and administrative staff at the level of section chief and above. The size of this shift includes about 349 heads of divisions, around 600 managerial officials, and roughly 750 section chiefs, with 49 police station heads changing assignments. This year, the number of women in leadership positions at the department will increase to 16, highlighting a gradual shift towards gender diversity within the police force.

Among the significant announcements on March 9th, Shota Shimizu, the head of the regional division, resigned following efforts to improve the response time of uniformed officers to incidents. His successor, Takao Fukuyama, has previously held positions including head of the investigation division and director of the Kouji Town police station. Additionally, Chise Yoshida, the police school head, also resigned; she had shifted the focus of traffic violation enforcement from high-violation areas to locations with frequent fatal accidents. Hiroshi Yamaguchi, who has been involved in improving conditions for young police officers, will take over her role.

In a notable historic appointment, Mayumi Miyazaki has been named the first female chief of the First Mobile Unit, responsible for security at key national sites such as the Imperial Palace and the Diet Building. Additionally, Aya Ikeda, the chief of the 6th Mobile Unit, will now head the disaster response division, a position also critical for managing responses to large-scale disasters within and outside the city. These changes reflect an ongoing evolution in the leadership structure of the Tokyo police force, with an emphasis on gender equality and modernization in various operational areas.
