Japan (日本, Nihon or Nippon^?, officially 日本国 Nippon-koku or Nihon-koku) is an island country in East Asia. Located in the Pacific Ocean, it lies to the east of the Sea of Japan, China, North Korea, South Korea and Russia, stretching from the Sea of Okhotsk in the north to the East China Sea and Taiwan in the south. The characters which make up Japan's name mean "sun-origin", which is why Japan is sometimes identified as the "Land of the Rising Sun".

Japan is an archipelago of 6,852 islands. The four largest islands are Honshū, Hokkaidō, Kyūshū and Shikoku, together accounting for 97% of Japan's land area. Most of the islands are mountainous, many volcanic; for example, Japan’s highest peak, Mount Fuji, is a volcano. Japan has the world's tenth-largest population, with about 128 million people. The Greater Tokyo Area, which includes the de facto capital city of Tokyo and several surrounding prefectures, is the largest metropolitan area in the world, with over 30 million residents.

Nikkō (日光市, Nikkō-shi^?, literally "sunlight" or "sunshine") is a city located in the mountains of Tochigi Prefecture, Japan. Located approximately 140 km north of Tokyo and approximately 35 km west of Utsunomiya, the capital of Tochigi, it is a popular destination for Japanese and international tourists, housing the mausoleum of shogun Tokugawa Ieyasu (Nikkō Tōshō-gū) and that of his grandson Iemitsu (Iemitsu-byō Taiyū-in), as well as the Futarasan Shrine, which dates to the year 767. There are also many famous hot springs (onsen) in the area. Elevations range from 200 to 2,000 m. The mountains west of the main city are part of Nikkō National Park and contain some of the country's most spectacular waterfalls and scenic trails.

As of January 1, 2008, the city has an estimated population of 92,181.

Nikkō Tōshō-gū (日光東照宮^?) is a Shinto shrine located in Nikkō, Tochigi Prefecture, Japan. It is part of the "Shrines and Temples of Nikkō", a UNESCO World Heritage Site.

Tōshō-gū is dedicated to Tokugawa Ieyasu, the founder of the Tokugawa shogunate. Initially built in 1617, during the Edo period, while Ieyasu's son Hidetada was shogun, it was enlarged during the time of the third shogun, Iemitsu. Ieyasu is enshrined here, and his remains are entombed here.

During the Edo period, the Tokugawa shogunate carried out stately processions from Edo to the Nikkō Tōshō-gū along the Nikkō Kaidō. The shrine's annual spring and autumn festivals reenact these occasions, and are known as "processions of a thousand warriors."

Five structures at Nikkō Tōshō-gū are categorized as National Treasures of Japan, and three more as Important Cultural Properties. Additionally, two swords in the possession of the shrine are National Treasures, and numerous other objects are Important Cultural Properties. Famous buildings at the Tōshō-gū include the richly decorated Yōmeimon, a gate that is also known as "higurashi-no-mon." The latter name means that one could look at it until sundown, and not tire of seeing it. Carvings in deep relief, painted in rich colors, decorate the surface of the structure. The next gate is the karamon decorated with white ornaments. Nearby, a carving of the sleepy cat, "Nemuri-neko", is attributed to Hidari Jingorō.

A Tōshō-gū (東照宮) is any Shinto shrine in which Tokugawa Ieyasu is enshrined with the name Tōshō Daigongen (東照大権現). Ieyasu was the founder of the Tokugawa shogunate (1603-1868), which is the third and last of the shogunal governments in Japanese history.

Tōshō-gū shrines are found throughout Japan. The most famous Tōshō-gū is located in Nikkō in Tochigi Prefecture. It is one of Japan's most popular destinations for tourists.

Ieyasu's son, the second shogun Hidetada, ordered the construction of the Nikkō Tōshō-gū. Later, the third shogun Iemitsu had the shrine greatly enlarged and lavishly decorated.

The Tōshō-gū at Ueno Park in Tokyo is also widely known. Another, at Kunōzan in Shizuoka prefecture, rivals Nikkō's for decorative splendor. A Tōshō-gū can also be found at Miyanochō, in Sendai.

During the Edo period, these shrines reached 500 in number. After the Meiji Restoration, many were abandoned, and others united with shrines in the area. Presently, there are about 130 Tōshō-gū.

The Kantō region (関東地方, Kantō-chihō^?) is a geographical area of Honshū, the largest island of Japan. The region encompasses seven prefectures which overlaps the Greater Tokyo Area: Gunma, Tochigi, Ibaraki, Saitama, Tokyo, Chiba, and Kanagawa. Within its boundaries, slightly more than 40 percent of the land area is the Kantō Plain. The rest consists of the hills and mountains that form the land borders.

The UNESCO World Heritage Site Shrines and Temples of Nikkō encompasses 103 buildings or structures and the natural setting around them. It is located in Nikkō, Tochigi Prefecture, Japan. The buildings belong to two Shinto shrines (Futarasan Shrine and Tōshō-gū) and one Buddhist temple (Rinnō-ji). Nine of the structures are designated National Treasures of Japan while the remaining 94 are Important Cultural Properties. UNESCO listed the site as World Heritage in 1999.
