Japan is an island nation in East Asia, an archipelago of nearly 7,000 islands strung along the Pacific edge of the continent. Four large islands (Honshu, Hokkaido, Kyushu, and Shikoku) hold most of its people and cities, with mountainous, forested interiors pushing the population onto narrow coastal plains. It is one of the world's most technologically advanced societies, famous for weaving deep tradition together with relentless innovation.
For long stretches of its history Japan was governed not by its emperors but by military rulers, the shoguns, who commanded a warrior aristocracy of samurai. From the early 1600s the Tokugawa shogunate sealed the country off from most foreign contact, a self-imposed isolation that lasted more than two centuries. That ended in 1853 when American warships forced Japan open to trade. The shock triggered the Meiji Restoration of 1868, which abolished feudal rule, restored the emperor as a symbol of unity, and launched a furious drive to modernise. Within decades Japan became an industrial and military power.
By tradition Japan was founded in 660 BC by Emperor Jimmu, said to descend from the sun goddess Amaterasu, beginning an imperial line claimed to be unbroken ever since. This origin story shaped Japanese identity for centuries, but historians treat the early emperors and the precise founding date as legend rather than documented fact, since they predate any written record. The historicity of these first rulers is disputed, even as the symbolic continuity of the throne remains culturally central.
Japan sits on the Pacific Ring of Fire, a zone of intense seismic and volcanic activity, which makes earthquakes and the threat of tsunamis a constant feature of life and a powerful influence on its engineering and culture. Mountains and forests cover roughly three-quarters of the land, leaving little flat ground, so cities crowd onto the coastal plains. The most famous peak, Mount Fuji, is an active volcano and a national icon.
The national flag, the Hinomaru (meaning "circle of the sun"), is among the simplest and most recognisable in the world: a single crimson disc centred on a white field. The red circle represents the sun, fitting for a country whose name means "origin of the sun" and which is often called the Land of the Rising Sun. Versions of the sun-disc banner were flown for centuries before it became the formal national flag, by law, in 1999.
Japanese spiritual life blends two traditions that most people follow side by side. Shinto, the indigenous faith, venerates kami, spirits present in nature, ancestors, and sacred places, and is woven into festivals, shrines, and rites of passage. Buddhism, which arrived from the Asian mainland in the sixth century, coexists with it and shapes funerary customs and temple life. Most Japanese do not see these as exclusive memberships but as complementary practices, and formal religious affiliation is famously fluid.
Japanese cooking, or washoku, is built on rice, seafood, soy, and seasonal vegetables, prized for freshness, balance, and careful presentation. Sushi and sashimi showcase raw fish at its purest, while dishes like tempura, ramen, udon, and grilled yakitori fill everyday tables. Fermented staples such as miso and soy sauce give the food its savoury depth, the quality often called umami. The tradition is distinctive enough that washoku is recognised by UNESCO as intangible cultural heritage.
Mountains cover most of Japan, so only a small share of the land can be farmed, and holdings tend to be tiny and intensively worked. Rice is the central crop, woven into both diet and ritual, and the country aims for self-sufficiency in it even as overall food imports run high. Farmers also grow vegetables, fruit, and tea, while the surrounding seas make Japan one of the largest harvesters and consumers of fish on Earth. An ageing rural workforce is a pressing long-term concern.
Japan's modern history turned on the twentieth century. Its imperial expansion across Asia and the Pacific drew it into the Second World War, which ended after the atomic bombings of Hiroshima and Nagasaki and the country's surrender in 1945. From the ruins Japan rebuilt with extraordinary speed into a peaceful democracy and the second largest economy in the world, an era remembered as the postwar economic miracle.
Japan is home to roughly 124 million people, most of them packed into dense urban regions, above all the Greater Tokyo Area, the largest metropolitan region in the world. Japanese society enjoys some of the highest life expectancies anywhere, but it now faces a steep demographic challenge: a low birth rate and an ageing population mean the total number of people has begun to decline, a trend reshaping its economy and public life.
