The history of Nerima is a journey from agricultural outskirts to one of the iconic special wards of modern Tokyo. Although Nerima was formed as an administrative unit relatively recently, its land has deep historical roots. During the Edo period (1603–1868), the territory of modern Nerima consisted primarily of farmland that supplied the growing capital with produce. It was a rural area composed of numerous villages.
Nerima received official special ward status on August 1, 1947, when it was separated from the neighboring Itabashi ward. This moment marked the formal birth of Nerima in its current form. Its further development was driven by several key events. After the devastating Great Kanto Earthquake of 1923, many residents from central Tokyo began moving to the outskirts, leading to population growth. Its convenient location northwest of central Tokyo and post-war development, including the placement of Japan Self-Defense Forces bases, also contributed to the district's growth and infrastructure formation.
Initially, Nerima's economy was entirely agrarian. The region was famous for growing vegetables, particularly "daikon" radish, potatoes, and gobo (burdock root). Remarkably, Nerima still retains more agricultural land today than any other special ward in Tokyo, producing about 40% of all the capital's cabbage. Later, the district's cultural identity began to change rapidly when Nerima became known as the birthplace of Japanese anime. Famous studios such as Toei Animation and Mushi Production settled here, forever linking it to the history of the global animation industry.
