Poluwat

Poluwat is a coral atoll located in the Federated States of Micronesia. It serves as a municipality within the state of Chuuk. Specifically, the atoll sits in the northwestern region known as Oksoritod. It is also part of the western area called Pattiw. An atoll is a ring-shaped coral reef that surrounds a central lagoon.

The physical structure of the atoll consists of five distinct islets. These islands lie along the rim of the coral reef. The total land area of these islands is 3.4 square kilometers. Because the lagoon is quite small, the entire atoll covers 7 square kilometers. The islets are arranged in a specific order starting from the southeast. Polowat sits in the southeast of the ring. Moving counterclockwise, you find Alengelap and To on the northern rim. Alei is located on the western side. Finally, Haw Islet marks the southern corner.

Each islet has its own unique physical characteristics. Alei and Polowat are the two largest islands in the atoll. These larger islands feature breadfruit trees in their centers. Coconut palms grow along their shores. The smaller islets, such as Alengelap, To, and Haw, are different. Haw is the smallest islet at only 0.02 square kilometers. These smaller islands are rocky and wooded. They contain very few coconut palms compared to the larger ones. Alei and Polowat represent the westernmost land features of Chuuk state.

The geography of the region extends far beyond the visible islands. The Uranie Bank is a large feature that extends 26 kilometers southeast from Poluwat. This bank has water depths ranging from 11 to 61 meters. Scientists might consider Poluwat and the Uranie Bank as one large structure. This submerged atoll structure would have a total size of 332 square kilometers. Additionally, the Enderby Bank lies about 5 kilometers west-northwest of Alei Island. This bank is composed of coral and has a depth of 16 meters.

Human history on the atoll includes early exploration and modern conflict. A Spanish naval officer named Juan Antonio de Ibargoitia discovered the atoll. He was commanding a vessel named the Filipino. This discovery took place on April 7, 1801. Later, the islands became part of the Pacific theater during World War II. A Japanese garrison was stationed there during the conflict. This group included 2,769 men from the 11th Independent Mixed Regiment. They were led by Colonel Tatsuo Yasui. The garrison also included 243 men from the Imperial Japanese Navy (IJN).

World War II left a heavy impact on the local population and landscape. The Japanese army faced severe food shortages during the war. Because of this, two of the three army battalions moved to Truk. Despite this move, many people still suffered. Specifically, 335 soldiers from the Imperial Japanese Army and 211 from the IJN died. These deaths were caused by hunger and illness. Today, the islands hold many relics from this era. On Alei, you can find Japanese defense bunkers. There is also a beached ship that was attacked by American aircraft. An American plane from the war rests at the bottom of the lagoon.

Many historical sites on the atoll are still preserved today. One notable landmark is a white concrete lighthouse tower on the northwest end of Alei. This tower stands 40 meters high. The Japanese Lighthouse is officially listed on the U.S. National Register of Historic Places. On the island of Polowat, people live in three villages on the west side. These villages face the lagoon. According to the 2000 census, the total population was 1,015 people. The villages are named Relong, Lukaf, and Rewow. The atoll also maintains modern connections through a local radio station.
