Records of heads of state
Officially, the current Emperor of Japan, Akihito is the 125th in line from the first emperor Jimmu, who is variously believed to have reigned in the 1st or 7th century BC. The earliest documentary evidence is only for the 29th emperor, Kinmei (AD 509–571); however, this is sufficient such that even the most conservative of estimates still places the Japanese imperial family as among the oldest lines in the world today.
Fourth Abe Cabinet
The Fourth Abe Cabinet was formed in November 2017 by Prime Minister Shinzō Abe and is the current government of Japan. The government is a coalition between the Liberal Democratic Party and the Komeito (which had changed its name from "New Komeito" in the 2012–2014 term) and controls both the upper and lower houses of the National Diet.
