Imperial Conference (御前会議 Gozen Kaigi) (literally, a conference before [the emperor]) was an extraconstitutional conference on foreign matters of grave national importance that was convened by the government of the Empire of Japan in the presence of the Emperor.
After the implementation of the Meiji Constitution, day-to-day affairs in the Meiji government were managed by a cabinet system arranged around the emperor as the head of state and the prime minister as the aide of the emperor.
However, on critical matters, extraconstitutional conferences were called to obtain final imperial approval for specific courses of action, which had already been previously decided upon by the civilian government, elder statesmen (genro) and/or the military authorities at Liaison Conferences (Renraku kaigi). As a ruler, the emperor listened to discussions, but remained silent through the proceedings. That the emperor would ever disagree, let alone veto, the prearranged decisions presented at the Gozen Kaigi was unthinkable.
Typically attending the Gozen Kaigi were (in addition to the Emperor himself):
Press announcements were typically issued immediately after each Gozen Kaigi, listing attendees, what each person wore, and stressing the unanimity of any decision.
The first Gozen Kaigi was convened just before the First Sino-Japanese War. Others were held just before the Russo-Japanese War, entry into World War I, the signing of the Tripartite Pact, and various times during the Second Sino-Japanese War, and notably on 6 September, 5 November, and on 1 December 1941, just before the attack on Pearl Harbor.
