Kitaarima (北有馬町, Kita-Arima-chō) was a town located in Minamitakaki District, Nagasaki Prefecture, Japan.
On March 31, 2006, Kitaarima, along with the towns of Arie, Fukae, Futsu, Kazusa, Kuchinotsu, Minami-Arima and Nishi-Arie (all from Minamitakaki District), was merged to create the city of Minamishimabara.
[2][3] Both Kita-Arima and Minami-Arima were part of what was known as Arima County in the south-eastern portion of the Shimabara Peninsula until they were split into two separate towns in 1889 during the Meiji Era.
Kita-Arima town is further split into smaller hamlets; Tanigawa, Sakaueshita, Tabira, Saishoji, Oriki.
Kitaarima was a stop on the now defunct Shimatetsu train line which connected all of the towns from Kazusa to Isahaya.
The most important is Festivitus Natalis, the town's Christmas festival held at the elementary school sports field.
Other sights of interest include Sunset Hill at the highest point in Kita-Arima-chō that overlooks Obama-chō to the northeast.
