Iruma district

Iruma district is an administrative region in Saitama Prefecture made up of three towns. It sits in the Musashino uplands and mixes rural areas with growing proximity to the Tokyo metropolitan area.

The area became an administrative district during Japan's Meiji period of modernization. Over the 20th century, several towns within it developed into cities and experienced rapid growth.

The region is known for growing Sayama green tea, a crop that shapes the landscape and daily life of residents. Visitors can see these tea plantations and understand how central this tradition remains to the communities.

The area sits near Tokyo and is well served by public transportation. It works well for exploring whether you want to see traditional rural spots or areas closer to Tokyo.

Some towns in the district, like Fukuoka and Fujimi, became cities in the mid-20th century and transformed significantly. This shows how the region shifted from purely rural to a mixed landscape.
