The 4th Tank Regiment was created in 1934 by an upgrade of the 4th Tank Battalion. The 4th Tank Regiment participated in the Battles of Khalkhin Gol against the Soviet Union in 1939. The commander was Tamado Yoshio, and the 4th Tank Regiment was brigaded into the 1st Tank Corps with the 3rd Tank Regiment, the group under the overall command of Major General Yasuoka. The 4th Tank Regiment at that time was equipped with mostly light tanks, complementing the medium tanks of the 3rd Tank Regiment. The 4th Tank Regiment order of battle at this time was:
