"Web Japan was launched with the aim of helping people around the world get to know more about Japan and the Japanese. With more than about 300 million hits per year from around the world, it has become one of Japan’s leading websites for information on the country.
The site provides highly reliable information on Japan across many different genres including culture, sightseeing, society, history and nature. The content is provided primarily in English, but a portion of the site is multilingual."
Personal Note: The "mother site" for Kids Web Japan. The two together make a fantastic resource for learning.
