Japan has close economic and military relations with the United States, with which it maintains a security alliance. It is the world’s fifth-largest donor of official development assistance, donating US$9.2 billion in 2014. Since the late 19th century, the judicial system has been largely based on the civil law of Europe, notably Germany. Historically influenced by Chinese law, the Japanese legal system developed independently during the Edo period through texts such as Kujikata Osadamegaki. It consists of a lower House of Representatives with 465 seats, elected by popular vote every four years or when dissolved, and an upper House of Councillors with 248 seats, whose popularly-elected members serve six-year terms.

As a growing number of younger Japanese are not marrying or remaining childless, Japan’s population is expected to drop to around 88 million by 2065. As of 2025update, over 29.3% of the population is over 65, or more than one in four out of the Japanese population. The country has therefore aimed to diversify its sources and maintain high levels of energy efficiency. The Sendai Nuclear Power Plant restarted in 2015, and since then several other nuclear power plants have been restarted.

Murasaki Shikibu’s The Tale of Genji and the lyrics of Japan’s national anthem “Kimigayo” were written during this time. This marked the beginning of the Heian period (794–1185), during which a distinctly indigenous Japanese culture emerged.

The Ryukyu Islands, which include Okinawa, are a chain to the south of Kyushu.
