Tokyo is the capital of Japan and the largest city in the world by population, with over 37 million people in the greater Tokyo area.

The 16th century saw the rise of Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu, who were instrumental in unifying Japan under a centralized government.

Japan is home to many natural hot springs, known as onsen, which are popular destinations for relaxation and rejuvenation.
