Geography
Geography
Sōka is situated in the southeast corner of Saitama Prefecture approximately 30 kilometers away from downtown Tokyo. It is surrounded to the east by the cities of Yashio, Misato and Yoshikawa, and to the west by Kawaguchi. To the north is Koshigaya and to the south Adachi Ward of Metropolitan Tokyo.The city is in the center of the Kanto Plain and is mostly lowland with an elevation of only three meters above sea level. The Ayase River flows through the city, which was subject to frequent flooding despite various flood control measures taken since the Edo Period. Sōka was once a peaceful agricultural area surrounded by water and greenery, but as a result of urbanization, the once abundant greenery and clean water was adversely affected. Now, Sōka is promoting a "town of greenery and water based on history and the natural features of the area". Creation of areas of greenery reflecting the changes of the four seasons, and the restoration of waterways and environs is being advanced.

History
History
The area of Sōka has been settled since at least the late Yayoi to early Kofun period, as evidenced by numerous burial mounds from 250-400 AD found within the city borders. In the Nara period, it became part of Musashi Province. In the Kamakura period, per the Azuma Kagami, large areas were under control of Tsurugaoka Hachiman-gu in Kamakura. The name "Sōka" first appears in historical documents in 1573. During the Edo period, the area was tenryo territory under the direct control of the Tokugawa shogunate and Sōka-shuku developed as a post station on the Nikkō Kaidō highway from 1630. Following the Meiji restoration, the area became part of Kitaadachi District, Saitama and Sōka Town was created with the establishment of the modern municipalities system on April 1, 1889. Sōka annexed the neighboring villages of Yatsuka and Shinden on January 1, 1955, followed by the village of Kawayanagi on August 1, 1955. On November 1, 1955, Sōka was elevated to city status. Following this, rapid population expansion and urbanization took hold due to strong economic growth which was fueled by its proximity to Tokyo. The city was proclaimed a tokureishi on April 1, 2004 with increased local autonomy.
