Timeline

The Heian period is the last division of classical Japanese history, running from 794 to 1185. It followed the Nara period, beginning when the 50th emperor, Emperor Kammu, moved the capital of Japan to Heian-kyō. Heian (平安) means 'peace' in Japanese. It is a period in Japanese history when the Chinese influences were in decline and the national culture matured. The Heian period is also considered the peak of the Japanese imperial court, noted for its art, especially poetry and literature. Two syllabaries unique to Japan, katakana and hiragana, emerged during this time. This gave rise to Japan's famous vernacular literature, with many of its texts written by court ladies who were not as educated in Chinese as their male counterparts.

The Sengoku period was the period in Japanese history in which civil wars and social upheavals took place almost continuously in the 15th and 16th centuries. The Kyōtoku incident (1454), Ōnin War (1467), or Meiō incident (1493) are generally chosen as the period's start date, but there are many competing historiographies for its end date, ranging from 1568, the date of Oda Nobunaga's march on Kyoto, to the suppression of the Shimabara Rebellion in 1638, deep into what was traditionally considered the Edo period. Regardless of the dates chosen, the Sengoku period overlaps substantially with the Muromachi period (1336–1573).

Hiroshima (広島市, Hiroshima-shi; English: , also UK: , US: , Japanese: [çiɾoɕima] ) is the capital of Hiroshima Prefecture in Japan. As of June 1, 2019, the city had an estimated population of 1,199,391. The gross domestic product (GDP) in Greater Hiroshima, Hiroshima Urban Employment Area, was US$61.3 billion as of 2010. Kazumi Matsui has been the city's mayor since April 2011. The Hiroshima metropolitan area is the second largest urban area in the Chugoku Region of Japan, following the Okayama metropolitan area. Hiroshima was founded in 1589 as a castle town on the Ōta River delta. Following the Meiji Restoration in 1868, Hiroshima rapidly transformed into a major urban center and industrial hub. In 1889, Hiroshima officially gained city status. The city was a center of military activities during the imperial era, playing significant roles such as in the First Sino-Japanese War, the Russo-Japanese War, and the two world wars. Hiroshima was the first military target of a nuclear weapon in history. This occurred on August 6, 1945, in the Pacific theatre of World War II, at 8:15 a.m., when the United States Army Air Forces dropped the atomic bomb "Little Boy" on the city. Most of Hiroshima was destroyed, and by the end of the year between 90,000 and 166,000 had died as a result of the blast and its effects. The Hiroshima Peace Memorial (a UNESCO World Heritage Site) serves as a memorial of the bombing. Since being rebuilt after the war, Hiroshima has become the largest city in t

The Edo period, also known as the Tokugawa period, is the period between 1600 or 1603 and 1868 in the history of Japan, when the country was under the rule of the Tokugawa shogunate and some 300 regional daimyo, or feudal lords. Emerging from the chaos of the Sengoku period, the Edo period was characterized by prolonged peace and stability, urbanization and economic growth, strict social order, isolationist foreign policies, and popular enjoyment of arts and culture.

Bushidō (武士道; Japanese pronunciation: [bɯ.ɕiꜜ.doː]) is a samurai moral code concerning samurai attitudes, behavior, and lifestyle. Its origins date back to the Kamakura period, but the code was formalized in the Edo period (1603–1868). There are multiple types of bushido, which evolved significantly through history. Contemporary forms of bushido are still used in the social and economic organization of Japan. Bushido is also used as an overarching term for all the codes, practices, philosophies, and principles of samurai culture. It is loosely analogous to the European concept of chivalry, but with some major differences.

The Tokugawa shogunate, also known as the Edo shogunate, was the military government of Japan during the Edo period from 1603 to 1868.

Mount Fuji is an active stratovolcano located on the Japanese island of Honshu, with a summit elevation of 3,776.24 m. It is the highest mountain in Japan, the second-highest volcano on any Asian island, and the seventh-highest peak of an island on Earth. Mount Fuji last erupted from 1707 to 1708.

The Meiji Restoration (明治維新, Meiji Ishin; Japanese pronunciation: [mei.(d)ʑi iꜜ.ɕiɴ, meː-]), referred to at the time as the Honorable Restoration (御維新／御一新, Goi(s)shin), also known as the Meiji Renovation, Meiji Revolution, Meiji Regeneration, Meiji Reform, or Meiji Renewal, was a political event that restored imperial rule to Japan in 1868 under Emperor Meiji and led to the westernisation of Japan. Although there were ruling emperors before the Meiji Restoration, the events restored practical power to, and consolidated the political system under, the Emperor of Japan. The Restoration led to enormous changes in Japan's political and social structure and spanned both the late Edo period (often called the Bakumatsu) and the beginning of the Meiji era, during which time Japan rapidly industrialised and adopted Western ideas, production methods and technology. The origins of the Restoration lay in economic and political difficulties faced by the Tokugawa shogunate.

Tokugawa Ieyasu was a Japanese samurai, daimyo and the founder and first shogun of the Tokugawa shogunate of Japan, which ruled from 1603 until the Meiji Restoration in 1868. He was the third of the three "Great Unifiers" of Japan, along with his former lord Oda Nobunaga and fellow Oda subordinate Toyotomi Hideyoshi. The son of a minor daimyo, Ieyasu once lived as a hostage under daimyo Imagawa Yoshimoto on behalf of his father. He later succeeded as daimyo after his father's death, serving as ally, vassal, and general of the Oda clan, and building up his strength under Oda Nobunaga.

Kyoto ( or ; Japanese: 京都, Kyōto [kʲoꜜː.to] ), officially Kyoto City (京都市, Kyōto-shi; [kʲoː.toꜜ.ɕi] ), is the capital city of Kyoto Prefecture in the Kansai region of Japan's largest and most populous island of Honshu. As of 2020, the city had a population of 1.46 million, making it the ninth-most populous city in Japan. More than half (56.8%) of Kyoto Prefecture's population resides in the city. The city is the cultural anchor of the substantially larger Greater Kyoto, a metropolitan statistical area (MSA) home to a census-estimated 3.8 million people. It is also part of the even larger Keihanshin metropolitan area, along with Osaka and Kobe. Kyoto is one of the oldest municipalities in Japan, having been chosen in 794 as the new seat of Japan's imperial court by Emperor Kanmu. The original city, named Heian-kyō, was arranged in accordance with traditional Chinese feng shui following the model of the ancient Chinese capitals of Chang'an and Luoyang. The emperors of Japan ruled from Kyoto in the following eleven centuries until 1869. It was the scene of several key events of the Muromachi period, Sengoku period, and the Boshin War, such as the Ōnin War, the Honnō-ji Incident, the Kinmon incident, and the Battle of Toba–Fushimi. The capital was relocated from Kyoto to Tokyo after the Meiji Restoration. The modern municipality of Kyoto was established in 1889. The city was spared from large-scale destruction during World War II and, as a result, its prewar cultural heritage has
