Why you should experience Police Museum in Tokyo, Japan.
Police Museum is an absorbing civic museum where Nishigotanda's metropolitan character, historical uniforms, investigative tools and interactive exhibits turn more than 150 years of Tokyo policing into a clear account of how public safety evolved alongside the capital.
Set along Daini Keihin near Nakahara Kaido and just steps from the Meguro River, the museum occupies the third floor of the TOC Building, where the Tokyo Metropolitan Police Department reopened it on April 24, 2026 after leaving its longtime Kyobashi home. Historical galleries follow policing from the Meiji period into contemporary Tokyo, while uniforms, equipment, major-case material and displays devoted to officers killed in service give institutional change a tangible human dimension. Simulators, forensic activities, animated exhibits and children's police uniforms translate present-day work into direct experience without reducing the historical material surrounding them. The result is a museum where Nishigotanda's dense modern cityscape becomes the setting for understanding the organization responsible for policing an increasingly complex Tokyo.
What you should know about Police Museum.
Police Museum is best known for carrying an institutional lineage that began in 1961 with the Metropolitan Police Department PR Center inside the former Kyobashi Police Station, became the Metropolitan Police Department Public Relations Center after the building was reconstructed in 1987, and adopted the Police Museum name in 1994. A major renovation closed the museum in April 2016 before a completely redesigned participatory exhibition reopened on April 29, 2017, expanding the historical presentation across multiple floors alongside simulations and police vehicles. Redevelopment of the Kyobashi 3-chome East District forced another closure on September 15, 2025, ending more than six decades of police interpretation on the Kyobashi site. The Metropolitan Police Department reopened Police Museum inside Nishigotanda's TOC Building on April 24, 2026, placing the collection within a commercial complex that itself opened on March 2, 1970 and contains approximately 174,013 square meters of floor area.
Toshiyoshi Kawaji gives the museum's historical collection its central human narrative, beginning as a Satsuma samurai who fought in the Boshin War before becoming superintendent of Tokyo's rasotsu patrolmen and joining the Iwakura Mission to study European police systems in 1872. Kawaji returned in 1873 advocating a centralized professional force, and the government established Tokyo Metropolitan Police on January 15, 1874 with Kawaji as its first chief, while rasotsu became junsa, the modern term for police officer. The organization was absorbed into the Home Ministry in January 1877 amid escalating former-samurai rebellions, with Tokyo officers subsequently deployed during the Satsuma Rebellion, before Tokyo Metropolitan Police was reestablished in 1881. Kawaji had died in 1879 after traveling again to Europe to investigate police and prison systems, leaving the institution he helped create to become the organizational foundation whose uniforms, equipment, cases and changing responsibilities now form the museum's historical narrative.
How to fold Police Museum into your trip.
Police Museum works naturally as the intellectual opening to an afternoon exploring Nishigotanda and the hills beyond, moving from the institutions that organize metropolitan life through the river that drove local industrialization before concluding in a preserved garden carrying a quieter strand of modern Japanese history.
Begin at Meguro River, where factories multiplied from the late Meiji period as waterside industry accelerated Shinagawa's population growth and urbanization, giving the museum's story of an expanding modern metropolis a physical counterpart in the district that developed around it. Continue uphill to Yakushi-ji Tokyo Annex, established as the eastern base of KΕin Takada's 1968 sutra-copying campaign to reconstruct Nara's HakuhΕ-era temple complex, occupying former incense master Kasetsu Yamamoto's residence and preserving his reconstructed kΕdΕ room. Conclude at Nemunoki Garden, opened in 2004 on the former ShΕda family residence where Empress Emerita Michiko grew up, with the garden named for her youthful poem and planted with Nemunoki, Princess Michiko roses and Imperial Household-donated water lilies. The progression moves from Tokyo's institutional history through the industrial geography of the Meguro River and Yakushi-ji's revival of Buddhist cultural practice into a garden shaped by Michiko's family memory, revealing the remarkably varied histories compressed around Gotanda.
