Japan

Japan is an island country in East Asia, set in the Pacific Ocean east of the Asian mainland. The Japanese archipelago holds four main islands and more than 14,000 smaller ones; there are 14,125 islands in all. The country is divided into 47 prefectures and eight traditional regions. Roughly 75% of the terrain is mountains and forest, so people and farmland gather on the eastern coastal plains. The land area is 377,975 square kilometers. A population estimate for 1 January 2026 stands at 122,950,000, while a separate census figure cites 126,146,099.

Tokyo is the capital and the country’s largest city, yet a trip rarely stays in one place. Honshu, the central island, carries Tokyo, Kyoto, and Osaka, and Mount Fuji at 3,776 meters — Japan’s highest peak. To the north lies Hokkaido, a broad island with a humid continental climate and snowy winters. Toward the southwest stretch the Ryukyu Islands, including subtropical Okinawa. That north–south reach can change the scenery in a few days by train or plane.

Most visits begin in Tokyo: broadcast towers and busy waterfronts. Kyoto follows, with wooden buildings and temples on the World Heritage list. Osaka is castle city and food city. Around Fuji, lakes and hot-spring resorts meet in Hakone. Hokkaido offers blue ponds, lavender fields, and snow-covered mountains. Okinawa means beaches and remote islands such as Ishigaki. Hiroshima opens onto Miyajima and its wooden gate standing in the water. This is not a copy of another country: city, mountain, and island take turns in quick succession.

Climate brings four clear seasons on Honshu, Shikoku, and Kyushu, while Hokkaido runs colder and Okinawa warmer. The national tourism site publishes separate guides for spring, summer, autumn, and winter. Japan holds 27 World Heritage sites — 22 cultural and 5 natural. Japanese is everyday language, the yen is the currency, and the clocks stay on Japan Standard Time with no daylight saving.

The clearest airports for travelers are Haneda and Narita for Tokyo, Kansai for Osaka and Kyoto, New Chitose for Hokkaido, and Naha for Okinawa. High-speed rail links the major cities on Honshu. The explore journey goes deeper, place by place.

UNESCO lists 27 sites for Japan. Mount Fuji joined the list in 2013, Kyoto’s historic monuments in 1994, and Itsukushima in 1996. Those dates help you shape a visit: the modern capital, then the former capital, then the peak, then a southern or northern island — according to the season you choose from the tourism board’s guides.[1,2,5,3,36,30,31,32,33,34,35]Source1.
