Information:  - Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people.  - Japan ("Nippon" or "Nihon" ; formally "" or "Nihon-koku", means "State of Japan") is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, It is lying off the eastern coast of the Asia Mainland (east of China, Korea, Russia) and stretching from the Sea of Okhotsk in the north to the East China Sea and near Taiwan in the southwest.   - Etymology. Rishiri derives its name from the Ainu language, and means "high island", or "island with a high peak", a reference to the altitude of Mount Rishiri above sea level.  - China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia. With a population of over 1.381 billion, it is the world's most populous country. The state is governed by the Communist Party of China, and its capital is Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau), and claims sovereignty over Taiwan. The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower.  - The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east.  - History. Hokkaido () was settled by the Ainu, Nivkh, and Orok before recorded history. The "Nihon Shoki", finished in 720 AD, is often said to be the first mention of Hokkaido in recorded history. According to the text, Abe no Hirafu led a large navy and army to northern areas from 658 to 660 and came into contact with the Mishihase and Emishi. One of the places Hirafu went to was called , which is often believed to be present-day Hokkaido. However, many theories exist in relation to the details of this event, including the location of Watarishima and the common belief that the Emishi in Watarishima were the ancestors of the present-day Ainu people.  - The Sea of Okhotsk is a marginal sea of the western Pacific Ocean, lying between the Kamchatka Peninsula on the east, the Kuril Islands on the southeast, the island of Hokkaido to the south, the island of Sakhalin along the west, and a long stretch of eastern Siberian coast (the Shantar Sea) along the west and north. The northeast corner is the Shelikhov Gulf. The sea is named after Okhotsk, the first Russian settlement in the Far East.  - The Ainu or the Aynu (Ainu  "Aynu"; Japanese: "Ainu"; Russian: "Ajny"), in the historical Japanese texts Ezo/Emishi/Ebisu or Ainu, are an indigenous people of Japan (Hokkaido, and formerly northeastern Honshu) and Russia (Sakhalin, the Kuril Islands and formerly the Kamchatka Peninsula).  - Rebun Island (, "Rebun-t") is an island in the Sea of Japan off the northwestern tip of Hokkaid, Japan. The island sits off the coast of Hokkaid. Rebun stretches from north to south and from east to west. The island covers approximately . Rebun Island is located northwest of Rishiri Island, and the two islands are separated by the Rebun Channel.  - The , also read as Ashihase and Shukushin, were a people of ancient Japan, believed to have lived along the northern portion of the coast of the Sea of Japan. The term Sushen, rendered , is found in Chinese records, but is annotated as Mishihase or Ashihase in Japanese language documents, which should have developed into *"Mishiwase" or *"Ashiwase" in Modern Japanese if the word had survived in colloquial speech.  - The Sea of Japan (see below for other names) is a marginal sea between the Japanese archipelago, Sakhalin, and the Asian mainland. The Japanese archipelago separates the sea from the Pacific Ocean. It is bordered by Japan, North Korea, Russia and South Korea. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also reflects in the fauna species and in the water salinity, which is lower than in the ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%.  - Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016.

Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara.  - Taiwan, officially the Republic of China (ROC), is a state in East Asia.

Taiwan is the most populous state that is not a member of the United Nations, and the one with the largest economy.  - The , sometimes translated as The Chronicles of Japan, is the second oldest book of classical Japanese history. The book is also called the . It is more elaborate and detailed than the "Kojiki", the oldest, and has proven to be an important tool for historians and archaeologists as it includes the most complete extant historical record of ancient Japan. The "Nihon Shoki" was finished in 720 under the editorial supervision of Prince Toneri and with the assistance of  no Yasumaro dedicated to Empress Gensh.  - Recorded history or written history is a historical narrative based on a written record or other documented communication.

Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm.
