A report on Imperial Japanese Army, Empire of Japan, Imperial Japanese Navy and Militarism

The Imperial Japanese Army (大日本帝国陸軍) was the official ground-based armed force of the Empire of Japan from 1868 to 1945.

The Imperial Japanese Navy (IJN; Kyūjitai: 大日本帝國海軍 Shinjitai: 大日本帝国海軍 'Navy of the Greater Japanese Empire', or 日本海軍 Nippon Kaigun, 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II.

It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy.

Some notable cases include the Ancient Assyrian Empire, the Greek city state of Sparta, the Roman Empire, the Aztec nation, the Mongol Empire, the Zulu Kingdom, the Kingdom of Prussia, the Habsburg/Habsburg-Lorraine Monarchies, the Ottoman Empire, the Empire of Japan, the Russian Empire, Soviet Union, North Korea, the United States of America, Nazi Germany, the Italian Empire during the rule of Benito Mussolini, the German Empire, the British Empire, and the First French Empire under Napoleon.

In 1947, with American involvement, a new constitution was enacted, officially bringing the Empire of Japan to an end, and Japan's Imperial Army was replaced with the Japan Self-Defense Forces.

One was the "Military Ministers to be Active-Duty Officers Law", which required the Imperial Japanese Army (IJA) and Imperial Japanese Navy (IJN) to agree to the Ministry of Army position in the Cabinet.

In 1874, the Taiwan expedition was the first foray abroad of the new Imperial Japanese Navy and Army after the Mudan Incident of 1871, however the navy served largely as a transport force.

Of the total, 20,300 were Imperial Japanese Army troops of the 5th Infantry Division under Lt. General Yamaguchi Motoomi; the remainder were 540 naval rikusentai (marines) from the Imperial Japanese Navy.

This was enacted by the Japanese in order to prevent militarism, which had led to conflict.

Totalitarianism, militarism, and expansionism were to become the rule, with fewer voices able to speak against it.

A long stretch of militaristic expansion and the start of the Second Sino-Japanese War in 1937 had exacerbated tensions with the United States, which was seen as a rival of Japan.
