Chibu is located on Chiburijima (知夫里島), the smallest of the Dōzen group of islands, and includes 18 smaller uninhabited islands located nearby waters. The Dōzen islands were formed from a single ancient volcanic island. The caldera of the volcano collapsed, leaving three main islands in a ring formation.[4]
Located on an island located in the Sea of Japan, Chibu is within the Sea of Japan climate zone. Summer 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 in Chibu, and what snow does fall usually melts quickly.
The nearest weather station is located in Ama on the nearby island of Nakanoshima. 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.
Chibujima was composed of 7 hamlets: Kōri (郡), Nibu (仁夫), Ōe (大江), Tataku (多沢), Usuge (薄毛), Kurii (来居), and Urumi (古海), which were united to form Chibu Village in 1909. The village is served by a sea port located in Kurii which provides ship transportation among the three islands of the Dozen group, to Okinoshima, and to the mainland. There is also a heliport for medical emergencies.
