The 4th Division (第4師団, Daiyon shidan^?) was an infantry division in the Imperial Japanese Army. Its call-sign was Yodo Division (淀兵団, Yodo-heidan^?) (from the Yodo River).

The 4th Division was formed in Osaka City in January 1871 as the Osaka Garrison (大阪鎮台, Osaka chindai^?), one of six regional commands created in the fledgling Imperial Japanese Army. The Osaka Garrison had responsibility for central region of Honshū (Kansai district), ranging from Shiga Prefecture to Hyōgo Prefecture. The six regional commands were transformed into divisions under the army reorganization of 14 May 1888.

The 4th regional command have played a vital role in the defeat of the Satsuma Rebellion in 1877.

During the First Sino-Japanese War in 1895, the 4th division has landed on Liaodong Peninsula and performed a security duties as part of army reserve, though its 7th Mixed Brigade was sent to northern Formosa in September 1895 during the Japanese invasion of Taiwan, and helped to pacify the Kapsulan (Yilan) district.
