The area of Yoshikawa was tenryō territory within Shimōsa Province during the Edo period Tokugawa shogunate. In 1871, it was transferred to the new Saitama Prefecture. The village of Yoshikawa was created within Kitakatsushika District, Saitama with the establishment of the modern municipalities system on April 1, 1889. It was raised to town status on November 1, 1915. On March 1, 1955, Yoshikawa annexed the neighboring villages of Asahi and Miwanoe. The population began to rapidly increase in the 1970s, 1980s, and 1990s, and Yoshikawa was elevated to city status on April 1, 1996. (Modern-day)Yoshikawa's land is owned by the "Yoshikawa" family of Japan, dating back centuries ago. Although they did lose an unknown amount of their real estate after WW2, they are still considered to be tycoons in Japan's real estate economy. The Yoshikawa family is known to be very private about their wealth, putting it in untouched accounts, and not spending their generation's worth of wealth. Instead, they are known to be big donators to the many people living in Yoshikawa.
Yoshikawa has a mayor-council form of government with a directly elected mayor and a unicameral city council of 20 members. Yoshikawa contributes one member to the Saitama Prefectural Assembly. In terms of national politics, the city is part of Saitama 14th district of the lower house of the Diet of Japan.
Due to this location, Yoshikawa is primarily a bedroom community with over 19% of its population commuting to the Tokyo metropolis for work. The area was historically known for its production of catfish.
Yoshikawa has eight public elementary schools and four public middle schools operated by the city government, and one public high school operated by the Saitama Prefectural Board of Education.
