Nanpō Islands

The Nanpō Islands (南方諸島 Nanpō Shotō) is a collective term for the groups of islands that are located to the south of the main islands of the Japanese archipelago. They extend from the Izu Peninsula west of Tokyo Bay southward for about 1,200 km (750 mi), to within 500 km (310 mi) of the Mariana Islands. The Nanpō Islands are all administered by Tokyo Metropolis.

The Hydrographic and Oceanographic Department of the Japan Coast Guard defines the Nanpō Shotō as follows:[1][2]

The Geospatial Information Authority of Japan, a government agency that is responsible for standardization of place names, does not use the term Nanpō Shotō, although it has agreed with the Japan Coast Guard over the names and extents of the subgroups of the Nanpō Shotō.[1]

Bonin Islands

The Bonin Islands, also known as the Ogasawara Islands (小笠原群島, Ogasawara Guntō), or, Yslas del Arzobispo, are an archipelago of over 30 subtropical and tropical islands, some 1,000 kilometres (540 nmi; 620 mi) directly south of Tokyo, Japan. The name "Bonin Islands" comes from the Japanese word bunin (an archaic reading of 無人 mujin), meaning "no people" or "uninhabited". The only inhabited islands of the group are Chichijima (父島), the seat of the municipal government, and Hahajima (母島).

Ogasawara Municipality (mura) and Ogasawara Subprefecture take their names from the Ogasawara Group. Ogasawara Archipelago (小笠原諸島, Ogasawara shotō) is also used as a wider collective term that includes other islands in Ogasawara Municipality, such as the Volcano Islands, along with three other remote islands (Nishinoshima, Minami-Tori-shima and Okinotorishima). Geographically speaking, all of these islands are part of the Nanpō Islands.

A total population of 2,440 (2015), 2,000 on Chichijima and 440 on Hahajima, lives in the Ogasawara Group, which has a total area of 84 square kilometres (32 sq mi).

Because the Ogasawara Islands have never been connected to a continent, many of their animals and plants have undergone unique evolutionary processes. This has led to the islands' nickname of "The Galápagos of the Orient", and their nomination as a natural World Heritage Site on June 24, 2011. The giant squid (genus Architeuthis) was photographed off the Ogasawara Islands for the first time in the wild on 30 September 2004, and was filmed alive in December 2006.A 25-meter-diameter radio telescope is located in Chichijima, one of the stations of the very-long-baseline interferometry (VLBI) Exploration of Radio Astrometry (VERA) project, and is operated by the National Astronomical Observatory of Japan.

Chichijima Airfield

Chichijima Airfield (父島飛行場, Chichijima Hikōjō) (ICAO: RJAO) is an airfield on the island of Chichi-jima in Japan. It has a landing slope facility for flying boats (e.g. Shin Meiwa US-1A/US-2) and a heliport for the Japan Maritime Self-Defense Force (JMSDF) Chichijima Naval Base.

Both bases were under the control of the United States Navy from shortly after Japan's surrender in 1945 up to 1968. During that time the naval base was known as

Chichi Jima Naval Base.

Geography of Japan

Japan is an island country comprising a stratovolcanic archipelago over 3,000 km (1,900 mi) along East Asia's Pacific coast. It consists of 6,852 islands. The 5 main islands are Hokkaido, Honshu, Kyushu, Shikoku and Okinawa. There are 6,847 'remote islands'. The Ryukyu Islands and Nanpō Islands are south and east of the main islands.

The territory extends 377,973.89 km2 (145,936.53 sq mi). It is the 4th largest island country in the world and the largest island country in East Asia. Japan has the sixth longest coastline 29,751 km (18,486 mi) and the eighth largest Exclusive Economic Zone of 4,470,000 km2 (1,730,000 sq mi) in the world.The terrain is mostly rugged and mountainous with 66% forest. The population is clustered in urban areas on the coast, plains and valleys. Japan is located in the northwestern Ring of Fire on multiple tectonic plates. East of the Japanese archipelago are three oceanic trenches. The Japan Trench is created as the oceanic Pacific Plate subducts beneath the continental Okhotsk Plate. The continuous subduction process causes frequent earthquakes, tsunami and stratovolcanoes. The islands are also affected by typhoons. The subduction plates have pulled the Japanese archipelago eastward, created the Sea of Japan and separated it from the Asian continent by back-arc spreading 15 million years ago.The climate of the Japanese archipelago varies from humid continental in the north (Hokkaido) to humid subtropical and tropical rainforest in the south (Okinawa Prefecture). These differences in climate and landscape have allowed the development of a diverse flora and fauna, with some rare endemic species, especially in the Ogasawara Islands.

Japan extends from 20° to 45° north latitude (Okinotorishima to Benten-jima) and from 122° to 153° east longitude (Yonaguni to Minami Torishima). Japan is surrounded by seas. To the north the Sea of Okhotsk separates it from the Russian Far East, to the west the Sea of Japan separates it from the Korean Peninsula, to the southwest the East China Sea separates the Ryukyu Islands from China and Taiwan, to the east is the Pacific Ocean.


Hahajima (母島, meaning Mother Island) is the second-largest island of the Ogasawara Islands (informally Bonin Islands) south of the Japanese main island chain. It is about 21 km2 (8 sq mi) in area with a population of 440.

The highest points are Chibusayama, (literally Breast Mountain), approximately 462 metres (1,516 ft), and Sakaigatake, 443 metres (1,453 ft). The largest island of the group, Chichijima is located approximately 50 km (31 mi) to the north. Together with nearby smaller islands like Anejima and Imōtojima and Mukōjima, Hahajima forms the Hahajima Rettō (母島列島), or in former times, the "Baily Group".

The island is within the political boundaries of Ogasawara Village, Ogasawara Subprefecture, Tokyo, Japan.

Japanese archipelago

The Japanese archipelago (日本列島, Nihon Rettō) is a group of 6,852 islands that form the country of Japan. It extends over 3,000 km (1,900 mi) from the Sea of Okhotsk northeast to the Philippine Sea south along the northeastern coast of the Eurasia continent. It consists of islands from the Sakhalin Island Arc, the Northeastern Japan Arc to the Ryukyu Islands and the Nanpō Islands. Japan is the largest island country in East Asia and the 4th largest island country in the world with 377,973.89 km2 (145,936.53 sq mi). It has the 8th largest exclusive economic zone of 4,470,000 km2 (1,730,000 sq mi).

Japanese colonial empire

The Japanese colonial empire constituted the overseas colonies established by Imperial Japan in the Western Pacific and East Asia region from 1895. Victories over China and Russia expanded the Japanese sphere of influence, notably in Taiwan and Korea, and southern Sakhalin became a colony of Japan as the Karafuto Prefecture in 1905.

Following seizures of German territories in 1914, the League of Nations granted Japan mandates over some former German possessions in the Western Pacific after World War I. With the Japanese expansion into Manchuria in the early 1930s, Japan adopted a policy of setting up and/or supporting puppet states in conquered regions. In this less obviously imperialist form Japan controlled many of the states of what it referred to as the Greater East Asia Co-Prosperity Sphere, a concept which gradually formed under Japanese influence from 1930 to 1945. Colonial control over the far-flung territories from Tokyo ended after the Allies defeated Japan in 1945: the extent of Japanese governance reverted to the four home islands, the Nanpō Islands, and the Ryukyu Islands.

Jōshin'etsu region

The Jōshin'etsu region (上信越地方, Jōshin'etsu chihō) is a region on the main Japanese island of Honshu, comprising parts of Gunma, Nagano, and Niigata Prefectures. It is a mountainous area with a large national park and numerous hot springs and ski resorts. It has long been a transportation corridor between the Kantō plain and coastal areas on the Japan Sea side of the island.

List of islands of Japan

Japan has 6,852 islands. Approximately 430 are inhabited. Japan is the largest island country in East Asia and the fourth largest island country in the world. Here's a list of islands of Japan.

List of regions of Japan

The regions of Japan are not official administrative units, but have been traditionally used as the regional division of Japan in a number of contexts. For instance, maps and geography textbooks divide Japan into the eight regions, weather reports usually give the weather by region, and many businesses and institutions use their home region as part of their name (Kinki Nippon Railway, Chūgoku Bank, Tōhoku University, etc.). While Japan has eight High Courts, their jurisdictions do not correspond to the eight regions below.

Mount Suribachi

Mount Suribachi (JPN.: 摺鉢山, Suribachiyama) is a 554 ft high mountain at the southwest end of the island Iwo Jima (now officially Iō-tō) in the northwest Pacific Ocean, under the administration of Ogasawara Subprefecture, Tokyo Metropolis, Japan.

The mountain's name derives from its shape, resembling a suribachi or "grinding bowl." It is also known as "Mount Pipe" (JPN: パイプ山, paipu-yama), since the sulfur gas and water vapor that rolls in from the summit, alongside the rest of the island, give the appearance of a smoking pipe when viewed from the sea.

Joe Rosenthal's famous photograph Raising the Flag on Iwo Jima was taken at the mountain's peak.

USS Devilfish (SS-292)

USS Devilfish (SS/AGSS-292), a Balao-class submarine, was a ship of the United States Navy named for the devil fish.

Devilfish was launched on 30 May 1943 by Cramp Shipbuilding Co., Philadelphia; sponsored by Mrs. Frank W. Fenno Jr.; and commissioned on 1 September 1944, Commander Edward Clark Stephen in command.

USS Pipefish (SS-388)

USS Pipefish (SS-388/AGSS-388), a Balao-class submarine, was the only ship of the United States Navy to be named for the pipefish.

Pipefish was laid down on 31 May 1943 by the Portsmouth Navy Yard. She was launched on 12 October 1943 sponsored by Mrs. George J. Bates, and commissioned on 22 January 1944, Lieutenant Commander William Nolin Deragon in command. "No No" Deragon graduated from the U.S. Naval Academy, class of 1934 and had received a Silver Star Medal for his performance as the Assistant Approach Officer aboard his previous boat, USS Seawolf (SS-197).

USS Pollack (SS-180), a Porpoise-class submarine, was the first ship of the United States Navy to be named for the pollack, a food fish resembling the true cod, but with the lower jaw projecting and without the barbel.

The first Pollack was laid down 1 October 1935 by the Portsmouth Navy Yard, in Kittery, Maine; launched 15 September 1936; sponsored by Miss Anne Carter Lauman; and commissioned 15 January 1937, Lt. Clarence E. Aldrich in command.

USS Steamer Bay

USS Steamer Bay (CVE-87) was a Casablanca class escort carrier of the United States Navy. She was laid down on 4 December 1943 at Vancouver, Washington, by the Kaiser Shipbuilding Company; launched on 26 February 1944; sponsored by Mrs. Henry S. Kendall; and commissioned on 4 April 1944, Captain Steadman Teller in command.

Steamer Bay held sea trials in Puget Sound and sailed for San Diego on 2 May. On the 14th, she headed for the New Hebrides, carrying the men and aircraft of Marine Air Group (MAG) 61. She arrived at Espiritu Santo on the 30th, unloaded, and began her return voyage to San Diego on 2 June. The carrier was on the west coast from 20 June to 19 July when she again steamed west, with 298 marines and 72 aircraft, bound for the Marshall Islands.

Steamer Bay arrived at Majuro on 1 August to discharge her cargo and passengers. She was routed back to Pearl Harbor and attached to the 3d Fleet as a carrier of replacement aircraft. Seventy-two planes were loaded on board; and the ship steamed for Seeadler Harbor, Manus Island, on 21 August. During the next two and one-half months, the carrier supplied replacement aircraft and pilots to Task Force (TF) 38 which was supporting the operations in the Palau and Philippine Islands. She spent the period from 15 November to 5 December at Pearl Harbor undergoing repairs and training. The ship returned to Seeadler Harbor on 17 December 1944 and was assigned to Task Group (TG) 77.4, the San Fabian Carrier Group, which sortied on 1 January 1945.

The group (Taffy 2), consisting of six escort carriers under the command of Rear Admiral Felix Stump, supported the Lingayen landings. While steaming through the Sulu and South China seas toward the Lingayen beaches, during the first week of January 1945, the group was the target of numerous enemy air attacks. Of the six carriers, Ommaney Bay (CVE-79) was sunk on 4 January by a kamikaze plane; and Manila Bay (CVE-61) and Savo Island (CVE-78) were damaged the next day. During the landings, the CVE's launched over 1,400 aircraft sorties in support of ground forces. Steamer Bay remained in the Philippine Islands with the 7th Fleet until she got underway on 31 January for Ulithi.

Steamer Bay anchored there from 5 February to 10 February, when she departed with units of the 5th Fleet for the invasion of Iwo Jima. She was with four other escort carriers which arrived at their assigned area of operations, 50 miles west of Iwo Jima, on 16 February. Their mission was to neutralize Japanese bases in the Nanpō Islands until 19 February (D-Day) and then provide air cover and direct support for the marines during the landings and the struggle for the strategic island.

Steamer Bay was relieved on 7 March and arrived at San Pedro Bay, Leyte, on the 12th. She sailed for the Ryukyus on 27 March and arrived in the operating area south of Okinawa on the morning of 1 April. She remained off Okinawa until 26 May when she sailed to Apra Harbor, Guam, for repairs. On 10 June, the carrier was ordered to join the 3d Fleet east of Miyako Jima and assist in neutralizing Japanese airfields in Sakishima Gunto. She conducted air strikes against the fields from 14 June to 22 June, when she sailed for Ulithi.

Steamer Bay stood out of Ulithi, on 3 July, with the Logistics Support Group resupplying the fast carrier forces during operations against the Japanese mainland. On the 20th, she was detached and sailed, via Guam and Pearl Harbor, for the west coast, arriving at San Diego on 10 August.

Steamer Bay was in drydock when hostilities with Japan ended, and she was given additional bunks to accommodate veterans returning from overseas. She sailed for Pearl Harbor, on 28 September, on her first “Magic Carpet” assignment.

Steamer Bay was assigned to the Pacific Reserve Fleet on 4 February 1946 and berthed at Tacoma, Washington. In January 1947, she was placed in reserve, out of commission. Her designation was changed from CVE-87 to CVHE-87 on 12 June 1955. The carrier was struck from the Navy list on 1 March 1959 and sold to Hyman-Michaels Co., Chicago, Illinois, on 29 August 1959 for scrap.

Steamer Bay received six battle stars for World War II service.
