Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asian mainland, it is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea in the south. The Japanese archipelago consists of four major islands—Hokkaido, Honshu, Shikoku, and Kyushu—and thousands of smaller islands, covering 377,975 square kilometers (145,937 sq mi). Japan has a population of over 123 million as of 2025, making it the eleventh-most populous country.

The capital of Japan and its largest city is Tokyo; the Greater Tokyo Area is the largest metropolitan area in the world, with more than 37 million inhabitants as of 2024. Japan is divided into 47 administrative prefectures and eight traditional regions. About three-quarters of the country's terrain is mountainous and heavily forested, concentrating its agriculture and highly urbanized population along its eastern coastal plains. The country sits on the Pacific Ring of Fire, making its islands prone to destructive earthquakes and tsunamis.

The first known habitation of the archipelago dates to the Upper Paleolithic, with the beginning Japanese Paleolithic dating to c. 36,000 BC. Between the fourth and sixth centuries, its kingdoms were united under an emperor in Nara, and later Heian-kyō. From the 12th century, actual power was held by military dictators (shōgun) and feudal lords (daimyō), and enforced by warrior nobility (samurai). After rule by the Kamakura and Ashikaga shogunates and a century of warring states, Japan was unified in 1600 by the Tokugawa shogunate, which implemented an isolationist foreign policy. In 1853, a United States fleet forced Japan to open trade to the West, which led to the end of the shogunate and the restoration of imperial power in 1868. In the Meiji period, Japan pursued rapid industrialization and modernization, as well as militarism and overseas colonization. In 1937, Japan invaded China, and in 1941 attacked the United States and European colonial powers, entering World War II as an Axis power. After suffering defeat in the Pacific War and two atomic bombings, Japan surrendered in 1945 and came under Allied occupation. Afterwards, the country underwent rapid economic growth and became one of the five earliest major non-NATO allies of the United States.

Japan is a constitutional monarchy with a bicameral legislature, the National Diet. A great power and the only Asian member of the G7, Japan has constitutionally renounced its right to declare war, but maintains one of the world's strongest militaries. A developed country with one of the world's largest economies by nominal GDP, Japan is a global leader in the automotive, robotics, and electronics industries, and has made significant contributions to science and technology. It has one of the world's highest life expectancies, though it is undergoing a population decline. Japan's culture is well known around the world, including its art, cuisine, film, music, and popular culture, which includes prominent animation, comics, and video game industries. (Full article...)

Japanese battleship Yamato under attack
Japanese battleship Yamato under attack
Operation Ten-Go was the last major Japanese naval operation in the Pacific Theater of World War II. Other renderings of this operation's title in English include Operation Heaven One and Ten-ichi-gō. In April 1945, the Japanese battleship Yamato, the largest battleship in the world, along with nine other Japanese warships, embarked from Japan on a deliberate suicide attack upon Allied forces engaged in the Battle of Okinawa. The Japanese force was attacked, stopped, and almost completely destroyed by United States (U.S.) carrier-borne aircraft before reaching Okinawa. Yamato and five other Japanese warships were sunk. The battle demonstrated U.S. air supremacy in the Pacific theater by this stage in the war and the vulnerability of surface ships without air cover to aerial attack. The battle also exhibited Japan's willingness to sacrifice large numbers of its people in desperate attempts (see kamikaze) to slow the Allied advance on the Japanese home islands. By early 1945, following the Solomon Islands campaign, the Battle of the Philippine Sea and the Battle of Leyte Gulf, the once formidable Imperial Japanese Navy's Combined Fleet was reduced to just a handful of operational warships and a few remaining aircraft and aircrew. Most of the remaining Japanese warships in the Combined Fleet were stationed at ports in Japan, with most of the large ships at Kure, Hiroshima. With the invasions of Saipan and Iwo Jima, Allied forces began their campaign against the Japanese homeland. As the next step before a planned invasion of the Japanese mainland, Allied forces invaded Okinawa on April 1, 1945. (Full article...)

Kusumoto Ine (楠本 イネ, 31 May 1827 – 27 August 1903; born Shiimoto Ine 失本 稲) was a Japanese physician. She was the first female doctor of Western medicine in Japan.

Flag of Fukui Prefecture
Fukui Prefecture is a prefecture of Japan located in the Chūbu region on Honshū island. The capital is the city of Fukui. Fukui originally consisted of the old provinces of Wakasa and Echizen, before the prefecture was formed in 1871. During the Edo period, the daimyō of the region was surnamed Matsudaira, and was a descendant of Tokugawa Ieyasu. The province faces the Sea of Japan, and has a western part (formerly Wakasa) which is a narrow plain between the mountains and the sea, and a larger eastern part (formerly Echizen) with wider plains including the capital and most of the population. The mountain side of the eastern part has much snow in winter. Fukui Prefecture is home to Maruoka-jō, the second oldest standing castle in Japan, after Inuyama Castle. It was built in 1576.
