Chibu is located on Chiburi Island (知夫里島 Chiburi-jima ), the smallest of the Douzen group of islands. These islands were formed from a single ancient volcanic island. The caldera of the volcano collapsed, leaving three islands in a ring formation.[5]
Chiburi Island is generally mountainous, but the south central area is somewhat flat. There are a number of sea cliffs, particularly on the western side of the island which faces the open expanse of the Sea of Japan. The elevation of Chiburi Island ranges from 0m (at sea-level) to 325m. The island has a land-area of approximately 13.7 km2. This includes 18 smaller uninhabited islands located near Chiburi Island.[1] The island's two most well-known natural features are Mount Akahage (アカハゲ山 Akahage-yama ) and Akakabe (赤壁 Akakabe , Sekiheki is an alternative reading). Akakabe is a unique sea-cliff in Oki composed of red rock.
The Village of Chibu is composed of 7 smaller neighborhoods, called chiku (地区 ) in Japanese. These neighborhoods are Kōri (郡 ), Nibu (仁夫 ), Ōe (大江 ), Tataku (多沢 ), Usuge (薄毛 ), Kurii (来居 ), and Urumi (古海 ). The village is served by a sea port located in Kurii which provides ship transportation among the 3 islands of Douzen, to Okinoshima, and to the mainland. There is also a heliport for medical emergencies.

As an island located in the Sea of Japan, Chibu is within the Sea of Japan climate zone. Summers temperatures, though usually mild, are exacerbated by high humidity. Winter temperatures are also generally mild, though exacerbated by strong wind. The surrounding ocean has a warming effect, making winters milder than the mainland. Consequently, there is very little snow on Chibu, and what snow does fall usually melts quickly.
The nearest weather station is located on the nearby island of Ama. Chibu's average annual high and low temperatures are 17.6°C (64°F) and 10.5°C (51°F), with yearly mean of 14.4°C (58°F). The record high and low temperatures are 34.9°C (95°F) and -2.9°C (27°F) respectively. The average yearly humidity is 76%. Chibu receives an average of 1,662 mm (65.43 in) of precipitation a year.

The earliest evidence of human habitation of Chibu is the tomb called Himemiya Shrine Ruins (姫宮神社遺跡 Himemiya-jinja iseki ) located in Urumi. The tomb is dated to the Jōmon period, 4000 years before present. Other ancient tombs built in the Yayoi (2300 BP) and Kofun (1700 BP) periods were also found. Also, the Oki Islands, including Chiburi Island, are mentioned in Japan's two most ancient texts, Kojiki and Nihon Shoki. In the Asuka period, the area became incorporated into the "Chibu district" (知夫郡 Chibu-gun ) encompassing both Chiburi Island and Nishinoshima.[1]
Over time, Chibu and Chiburi Island (知夫里島 Chiburi-jima ) have been written with various different kanji. These include the following, all of which are read "Chiburi": 知夫里, 知夫, 知夫利, 智夫, 道触 (see below), 知振, 千振, and 千波. There are two different theories regarding the name "Chiburi Island".[8]
The first and most likely is that the name came from the name of a Shinto god enshrined on Chiburi Island's Watatsu Island (渡津島 Watatsu-jima ). The god, called Chiburi no kami (道触の神 ), is a god protecting ships.[9] Since Chiburi Island is the closest to the mainland of the Oki Islands, ships coming to and departing from Oki would stop on Chiburi Island and ask the god for a safe voyage. Over time, the name "Chiburi" stuck and the island became known as "Chiburi Island" from whence the name "Chibu Village" was derived.[8][10]
The second theory is that the name came from the use of smoke signals sent between Chiburi Island and the mainland for communication. Since Chiburi Island is the closest, it was the easiest to see between the Oki Islands and the mainland.
The government of Chibu is organized with the mayor at the top, followed by the vice-mayor, treasurer, and 4 department chiefs, in that order. There is also a village board of 8 members elected for 4-year terms. The mayor of Chibu is elected for a 4-year term. The vice-mayor is appointed by the mayor and approved by the village board. The mayor and vice-mayor, as of November 2008, are Mr. Tatsuo Yada and Mr. Nobuyuki Watanabe, respectively. The board of education operates independently of the normal village office structure. The chief of the board of education is also appointed by the mayor and approved by the village board.
