Operational history[edit | edit source]
The Philippines[edit | edit source]
These plans called for air attacks against the Philippines, beginning on X-Day, by the 5th Army Air Force Division and the 11th Naval Air Fleet. At this time, Imperial Japanese Army and Imperial Japanese Navy units were to land on Batan Island, Luzon (at Aparri, Cagayan, Vigan, and Legazpi City), and at Davao, Mindanao, and to seize airfields. Following the elimination of American air support, the main body of the IJA 14th Army was to land at Lingayen Gulf, while another force landed at Lamon Bay. These forces were then to attack Manila in a pincer attack. After this, the islands of Manila Bay were to be taken. In the resulting Battle of the Philippines (1942), Japanese forces accomplished their primary objectives.
French Indochina[edit | edit source]
On July 22, 1941, Japanese forces invaded Vichy French Indochina and occupied its naval and air bases.
Netherlands East Indies[edit | edit source]
On January 18, 1942, the commander of 16th Army Lt. General Hitoshi Imamura arrived at Takao, Taiwan from his base at Saigon. He received an order to hasten the invasion preparation toward Java. But due to shipping shortages, he had to adjust the plans. On January 21, he arrived at Manila to inspect the IJA 48th Division and to have discussion with the commander of the IJN 3rd Fleet. The Netherlands East Indies was invaded in a three-prong attack by using 3 groups: western, center and eastern group.

The IJA 2nd Division of the IJA 16th Army, which was assembled in Taiwan, was ordered on January 25 to move in to Cam Ranh Bay and became the main force of western invasion group. At Cam Ranh Bay, the troops were trained for the tropical jungle warfare. On the 30th, the attack order was announced. The western group was carried aboard 56 transport ships and left for Java on February 18. By midnight on February 28, the ships landed at Merak and Bantam Bay on Java island.
Following the surrender of Hong Kong, the 228th, 229th and 230th Infantry Regiments from the IJA 38th Division were also deployed to Netherlands East Indies separately. On February 13, the 229th and 230th assaulted Palembang on Sumatra and then joined the main force. On February 28 midnight the 230th Infantry Regiment landed on Eretan Wetan on Java.
Center invasion group[edit | edit source]
The center group was composed of IJA 48th Division, left for Java on February 8, 1942 from Lingayen Gulf, in the Philippines. On February 25, the convoy arrived at Balikpapan and the Sakaguchi detachment (56th Regiment Group) joined the force. They landed at Kragan on Java by midnight February 28.
