Izumi-ku (泉区) is one of the 18 wards of the city of Yokohama in Kanagawa Prefecture, Japan. Located in the southwestern part of Yokohama, it is primarily a residential area that serves as a bedroom community for both Yokohama and Tokyo.
Overview
Izumi-ku covers an area of 23.58 square kilometers and, as of recent estimates, has a population of approximately 155,000 residents. The ward is characterized by its mix of modern residential developments, some remaining agricultural land (particularly in its western sections), and pockets of nature. Its name, "Izumi," means "spring" or "fountain," likely referring to the numerous natural springs or water sources in the area.
Geography
Izumi-ku is situated on the Sagami Plain, though it includes some undulating terrain. It borders Totsuka-ku to the east, Seya-ku to the north, Asahi-ku to the northeast, and the cities of Fujisawa and Yamato to the west and northwest, respectively. The Sakai River (境川), a significant local waterway, flows through the western part of the ward. The landscape is generally suburban, with residential complexes interspersed with smaller commercial zones and green spaces.
History
Historically, the area that is now Izumi-ku was part of Sagami Province. During the Edo period, it was a rural agricultural region. After the Meiji Restoration, it underwent various administrative reorganizations. In 1939, it was incorporated into the city of Yokohama as part of Totsuka-ku.
Rapid urbanization and population growth in the latter half of the 20th century led to the need for administrative division. On November 3, 1986, Izumi-ku was officially established by splitting off from Totsuka-ku, reflecting its distinct development trajectory and growing population. The development of railway lines in the area significantly contributed to its transformation into a suburban hub.
Demographics
Like many suburban wards in Japan, Izumi-ku has a relatively stable population composition. The population density is moderate, typical for areas that balance residential development with some open space. The ward is home to a mix of families, commuters, and a smaller elderly population.
Economy
The economy of Izumi-ku is predominantly residential and service-oriented. There are numerous retail establishments, supermarkets, and local businesses catering to the daily needs of its residents. While largely a bedroom community, it retains some historical agricultural activity, particularly in its western and southern areas, where small farms produce vegetables and other crops. There is limited heavy industry within the ward.
Education
Izumi-ku is served by a comprehensive network of public elementary and junior high schools. There are also several public high schools located within or immediately adjacent to the ward, such as Yokohama Izumi High School. While no major universities are directly located within Izumi-ku, institutions like Ferris University (in Totsuka-ku) are in close proximity, serving students from the area.

Transportation infrastructure is well-developed, facilitating access to central Yokohama and Tokyo:
- Railways:
