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 of the 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...)

A Japanese western-style toilet with bidet
A Japanese western-style toilet with bidet
There are two styles of toilets commonly found in Japan. The oldest type is a simple squat toilet, which is still common in public conveniences. After World War II, modern Western-type flush toilets and urinals became common. The current state of the art for Western-style toilets are the bidet toilets, which, as of 2004, are installed in more than half of Japanese households. In Japan, these bidets are commonly called Washlets, a brand name of Toto Ltd., and include many advanced features rarely seen outside of Asia. Depending on the exact model, these bidets are designed to open the lid when they sense a user nearby, wash the anus or vulva of the user (including a number of pulsating and massaging functions), dry afterwards with warm air, flush automatically and close the lid after use. During the Jōmon period, settlements were built in a horseshoe shape, with a central plaza in the middle and garbage heaps around the settlement. In these garbage heaps, calcified fecal remains of humans or dogs, so called coprolites, were found, indicating that these garbage dumps were also used as toilets. The earliest sewer systems are from the Yayoi period (300 BC to A.D. 250). These systems were used in larger settlements, probably in combination with toilets. A possible ritual site, that may also have been a toilet using flowing water, dating back to the early 3rd century was found in Sakurai, Nara. Another cesspit analyzed by archaeologists in detail was found at the site of the Fujiwara Palace in Kashihara, Nara, the first location of the imperial city from 694 to 710. This toilet was constructed over an open pit similar to an outhouse. (Full article...)

Masako Katsura (桂 マサ子, Katsura Masako, listen; 7 March 1913 – 20 December 1995), nicknamed "Katsy" and sometimes called the "First Lady of Billiards", was a Japanese carom billiards player who was most active in the 1950s. She was the first woman to compete and place among the best in the male-dominated world of professional billiards. First learning the game from her brother-in-law and then under the tutelage of Japanese champion Kinrey Matsuyama, Katsura became Japan's only female professional player. In competition in Japan, she took second place in the country's national three-cushion billiards championship three times. In exhibition she was noted for running 10,000 points at the game of straight rail.

After marrying a U.S. Army non-commissioned officer in 1950, Katsura emigrated to the United States in 1951. There she was invited to play in the 1952 U.S.-sponsored World Three-Cushion Championship, ultimately taking seventh place at that competition. Katsura was the first woman ever to be included in any world billiards tournament. Her fame cemented, Katsura went on an exhibition tour of the United States with eight-time world champion Welker Cochran, and later with 51-time world champion Willie Hoppe. In 1953 and 1954, she again competed for the world three-cushion crown, taking fifth and fourth places respectively. (Full article...)

Flag of Kumamoto Prefecture
Kumamoto Prefecture is a prefecture of Japan located on Kyūshū Island. The capital is the city of Kumamoto. Historically the area was called Higo province and was renamed to Kumamoto prefecture during the Meiji Restoration as part of the abolition of the feudal system. The current Japanese orthography for Kumamoto literally means "bear root/origin", or "origin of the bear". Kumamoto Prefecture is located in the center of Kyūshū, the southernmost of the four major Japanese islands. It is bordered by the Ariake inland sea and the Amakusa archipelago to the west, Fukuoka Prefecture and Ōita Prefecture to the north, Miyazaki Prefecture to the east, and Kagoshima Prefecture to the south. Mt. Aso (1592 m), an extensive active volcano, is in the east of Kumamoto Prefecture. This volcano is located at the center of the Aso caldera, the most famous caldera in Japan. Fourteen cities are located in Kumamoto Prefecture. Kumamoto hosts a large Honda automobile plant. In 2007, a Honda factory on the site began to produce non-silicon solar cells for homes and businesses, with a projected capacity roughly equivalent to 8,000 households/year.
