The economic development of the Shimōsa Plateau continued after the Meiji restoration of 1868.
An extensive rail network was established and replaced the slower canal routes to the capital.
Some of undeveloped areas in this plateau, including former ranches of shogunate, turned into military facility of Imperial Japanese Army (Narashinohara), imperial farm (Sanrizuka, Narita), or agricultural colonies, the aid for unemployed Shizoku.
Those colonies named after development order, such as: 
Hatsutomi (初富, Kamagaya)
Futawa (二和, Funabashi)
Misaki (三咲, Funabashi)
Toyoshiki (豊四季, Kashiwa)
Gokō (五香, Matsudo)
Mutsumi (六実, Matsudo)
Nanae (七栄, Tomisato)
Yachimata (八街, Yachimata)
Kumiage (九美上, Katori)
Tokura (十倉, Tomisato)
Toyoichi (十余一, Shiroi)
Toyofuta (十余二, Kashiwa)
Toyomi (十余三, Narita, Tako)
During the militarization of northern Chiba Prefecture that began in the early 20th century, the eastern area of the plateau was declared a military zone.
The Shimōsa Plateau was a center of the manufacture of war goods, notably of munitions and military aircraft, and saw the construction of numerous military facilities.
Shimofusa Air Base was constructed in 1945 by the Imperial Japanese Army Air Force on the border of Kashiwa and Kamagaya.
Most of the military facilities and industrial areas on the Shimōsa Plateau were destroyed by Allied bombing during World War II.
