SHOWA PERIOD: AD 1926-1989
Sh?wa period, corresponds to the reign of the emperor Hirohito. "The two Chinese characters (kanji) in the name Sh?wa translate as Bright Peace in Japanese. However, a more nuanced interpretation is Enlightened Harmony—with the added significance that the second character (wa) is commonly used in words that describe Japan or things Japanese.
The first part of the Sh?wa, from Hirohitos enthronement in 1926 to the end of World War II in 1945, is known as the early Sh?wa period. It is noted principally for the rise of militarism in Japan, Japanese aggression in China and elsewhere in East and Southeast Asia, and the countrys wartime defeat. The postwar Sh?wa decades were marked by Japans spectacular recovery and its rise as a global economic powerhouse second only to the United States, its former enemy and subsequent closest ally.
Unlike the Meiji Restoration (18681912)—corresponding to the rule of the Meiji emperor and synonymous among historians with Japans emergence as a modern country—none of the three succeeding ruling periods is widely used to designate the 20th-century history of Japan. The term Sh?wa literature, however, does denote a distinct phase in Japanese literature from about 1924 until the outbreak of World War II in 1939, and the Great Depression of the 1930s, which was particularly severe in Japan, is referred to as the Sh?wa Depression there"
