The Imperial Japanese Army initiated the Battle of Pasir Panjang in Kent Ridge Park in Singapore.

The Imperial Japanese Army was the principal ground force of the Empire of Japan from 1871 to 1945. It played a central role in Japan’s rapid modernization during the Meiji period, fought in numerous conflicts including the First Sino-Japanese War, the Russo-Japanese War, World War I, the Second Sino-Japanese War, and World War II, and became a dominant force in Japanese politics. Initially formed from domain armies after the Meiji Restoration, it evolved into a powerful modern military influenced by French and German models. The IJA was responsible for several overseas military campaigns, including the invasion of Manchuria, involvement in the Boxer Rebellion, and fighting across the Asia-Pacific during the Pacific War. Notorious for committing widespread war crimes, the army was dissolved after Japan's surrender in 1945, and its functions were succeeded by the Japan Ground Self-Defense Force.

The Battle of Pasir Panjang, which took place between 13 and 15 February 1942, was part of the final stage of the Empire of Japan's invasion of Singapore during World War II. The battle was initiated upon the advancement of elite Imperial Japanese Army forces towards Pasir Panjang Ridge on 13 February.
