Frequently asked questions

What is the official name of Japan?

Japan — Nihon or Nippon, 日本, "the origin of the sun," the name the country took for itself in the 7th century when it wrote to the Chinese court as the land where the sun rises; the constitution of 1947 calls the state Nihon-koku, the State of Japan, with no republic or empire in it, though the Emperor remains. "Japan" is the Malay and Portuguese rendering of the Chinese pronunciation, Cipangu in Marco Polo. The state counts its founding from the accession of the legendary Emperor Jimmu on 11 February 660 BC, kept as National Foundation Day.

What is the capital of Japan?

Tokyo — the "eastern capital," the fishing village of Edo that the Tokugawa shoguns made their seat in 1603 and the Emperor his in 1868, when it took its name from Kyoto, the capital of a thousand years before it; about 14 million people in the Tokyo Metropolis and about 37 million in the Greater Tokyo Area, the largest metropolitan area in the world for half a century until the UN's recount of 2025 placed Jakarta and Dhaka ahead of it. Yokohama, Osaka, the merchants' capital, Nagoya of Toyota, Sapporo, Fukuoka, Kobe and Kyoto are the other great cities.

How big is Japan, and how many people live there?

About 377,975 km² (145,937 sq mi) — a little smaller than California, larger than Germany — an archipelago of 14,125 islands by the recount of 2023, four of them holding nearly all the land: Honshu, Hokkaido, Kyushu and Shikoku, with Okinawa far to the south, strung 3,000 km along the Pacific edge of Asia. The census of 2020 counted 126,146,099 people; the Statistics Bureau estimates about 123 million for 2026, falling by about 900,000 a year since the peak of 128 million in 2008, the fastest decline of any large country, with three in ten over 65.

What are the highest and lowest points of Japan?

Mount Fuji — Fujisan — 3,776 m (12,388 ft), the dormant volcano 100 km southwest of Tokyo, last erupted in 1707, the sacred mountain of the prints and the pilgrims, a World Heritage site since 2013; and Hachirōgata, 4 m (13 ft) below sea level, the reclaimed lake bed of Akita. The islands sit on four tectonic plates on the Ring of Fire, with 111 active volcanoes, a tenth of the world's, and a fifth of the world's earthquakes above magnitude 6.

What currency does Japan use?

The yen (ISO code JPY, ¥ or 円), issued by the Bank of Japan since 1882 and the currency since the Meiji reform of 1871 — the third most traded in the world, at about 150 to the U.S. dollar, weakened through the 2020s; no subdivision in use, the sen and rin abolished in 1953. Clocks keep Japan Standard Time, UTC+9, all year, summer time never adopted; the years are counted by the imperial era as well as the Gregorian, 2026 being Reiwa 8.

Who governs Japan?

Prime Minister Sanae Takaichi of the Liberal Democratic Party, head of government since 21 October 2025 — the first woman in the office in the country's history, a conservative of the Abe school from Nara — who, four months into a minority government, called a snap election for 8 February 2026 and won the largest majority the party has taken in its seventy years: 316 of the 465 seats of the House of Representatives, a two-thirds supermajority with her partner Ishin's 36, over an opposition regrouped as the Centrist Reform Alliance of the Constitutional Democrats and Komeito. She was reappointed on 18 February 2026 with 354 votes. Emperor Naruhito, the 126th of a line the state counts from 660 BC, has reigned since 1 May 2019 as the symbol of the state without political power. The next election is due by February 2030.
