University of Guam (Chamorro: Unibetsedåt Guåhan) (U.O.G.) is a public land-grant university in Mangilao, Guam. It is accredited by the Western Association of Schools and Colleges and offers thirty-four degree programs at the undergraduate level and eleven at the master's level. Of the university's 3,387 students, 94% are of Asian-Pacific Islander ethnicity and nearly 72% are full-time (fall 2012 figures). A full-time faculty of about 180 work at the university.

The Japanese School of Guam (グアム日本人学校, Guamu Nihonjin Gakkō) is a Japanese international school in Mangilao, Guam. It includes both day school and weekend supplementary school divisions, and the school also holds Japanese language classes. As of April 2013 Toyohito Yoneyama is the chairperson of the school.

Mangilao is a village on the eastern shore of the United States territory of Guam. The village's population has decreased slightly since the island's 2010 census. Cliffs lie along much of the village's shoreline provide dramatic views, including of Pago Bay along Mangilao's southern coastline, but few of Mangilao's beaches are available for recreational uses. The island's main prison is in Mangilao.

The area code 671 is the local telephone area code of the United States territory of Guam. It was created with the beginning of permissive dialing on July 1, 1997, replacing Guam's previous International Telecommunication Union country code 671 at the end of permissive dialing on July 1, 1998.

Pago Bay is the largest bay on the U.S. territory of Guam, located at the mouth of Pago River on the island's eastern coast. There is extensive evidence of CHamoru settlement before Spanish colonization during the late seventeenth century. During the Spanish-Chamorro Wars, the Spanish transferred the populations of Tinian and Aguigan to the village of Pago (Pågu). However, a smallpox epidemic in 1856 killed much of the village's population and the Spanish moved survivors to other villages, leaving the bay shoreline largely uninhabited. The bay is popular with fishermen and recreationalists, and was the site of new housing development in the 2000s.

The Pago Bay Japanese pillboxes are a pair of World War II-era coastal defense pillboxes located on the shore of Pago Bay, located on the central east coast of Guam. Built out of steel-reinforced concrete mixed with coral stone, these two structures were built by Japanese defenders during their occupation of the island between 1941 and 1944. They were listed on the National Register of Historic Places in 1991 as Pagu' Pillbox I and Pagu' Pillbox II. Neither of these would have seen substantial action during the 1944 liberation of Guam, whose military activities were focused on the western, central, and northern parts of the island.

Guam is a U.S. territory in the western Pacific Ocean, at the boundary of the Philippine Sea. It is the southernmost and largest member of the Mariana Islands archipelago, which is itself the northernmost group of islands in Micronesia. The closest political entity is the Commonwealth of the Northern Mariana Islands (CNMI), another U.S. territory. Guam shares maritime boundaries with CNMI to the north and the Federated States of Micronesia to the south. It is located approximately one quarter of the way from the Philippines to Hawaii. Its location and size make it strategically important. It is the only island with both a protected harbor and land for multiple airports between Asia and Hawaii, on an east–west axis, and between Papua New Guinea and Japan, on a north–south axis. The island is a result of the volcanic activity created by subduction of the Pacific Plate under the Philippine Sea Plate at the nearby Mariana Trench, which runs from the east of Guam to the southwest. Volcanic eruptions established the base of the island in the Eocene, roughly 56 to 33.9 million years ago (mya). The north of Guam is a result of this base being covered with layers of coral reef, turning into limestone, and then being thrust by tectonic activity to create a plateau. The rugged south of the island is a result of more recent volcanic activity. Cocos Island off the southern tip of Guam is the largest of the many small islets along the coastline. Politically, Guam is divided into 19 villages. The majority of the population lives on the coralline limestone plateaus of the north, with political and economic activity centered in the central and northern regions. The rugged geography of the south largely limits settlement to rural coastal areas. The western coast is leeward of the trade winds and is the location of Apra Harbor, the capitol Hagåtña, and the tourist center of Tumon. The U.S. Defense Department owns about 29% of the island, under the management of Joint Region Marianas.

The Pago River is one of the longest rivers in the United States territory of Guam. It is fed by two inland rivers, Lonfit River and Sigua River. Rising close to the west coast, it traverses the island, flowing into the sea at Pago Bay in the central east coast. The village of Yona lies just to the south of the river's mouth.

The Guzman Water Catchment is a historic private water supply structure in the rural Nalao area of the village of Barrigada in the United States territory of Guam. It is a roughly rectangular structure, measuring 4.4 by 2.84 by 1.52 metres (14.4 ft × 9.3 ft × 5.0 ft), with an open top. It is fashioned out of locally gathered stone joined with lime-cement mortar. It was built in 1910 by Baldobino Charfauros on family-owned land, and is one of the oldest surviving rural catchment basins on the island. It is further distinguished from other catchment basins in that it has a substantial floor. These types of structures made it possible for Guamanian families to live on rural holdings where water access was otherwise a significant problem. The structure was listed on the National Register of Historic Places in 1994.

Barrigada (Chamorro: Barigåda) is a village in the United States territory of Guam. A largely residential municipality, its main village is located south of the Antonio B. Won Pat International Airport near the intersections of Routes 8, 10, and 16. The community east of the airport known as Barrigada Heights is considered an affluent neighborhood on the island, where homes have excellent views overlooking much of Guam including the island's airport and hotels along Tumon Bay. Another significant location is Mount Barrigada, nearly 200 meters above sea level. Its location in the center of the island means it houses most of the island's radio masts and towers; the position and height make it easier for radio signals to reach the entire island.

The Canada Water Wells, near jct. of Canada-Toto Rd.& Canada -Toto Loop Barrigada-Mangilao, GU, are water works that were built in 1937. They have also been known as Kanada, as Chochugu' and as To'tu. The structures were listed on the National Register of Historic Places in 2008; the listing included two contributing structures. A U.S. Geological Survey report in 2003 described the water of Guam, including identifying that there are approximately 180 water wells serving the needs of Guam, drawing on a lens-shaped aquifer.
