Sungai Tujoh, also abbreviated as Sg. Tujoh, is the westernmost point of Brunei. It is located in the Belait district. The name of the area is derived from two Bruneian Malay words - Sungai, which means river or stream, and Tujoh or the number seven. Literally, Sungai Tujoh is translated as the Seventh River or Seventh Stream in English.
Although it is sometimes referred to as Kampong Sungai Tujoh, there is no permanent settlement in the area. There is a custom and excise and immigration post at Sungai Tujoh, staffed by 46 immigration officers, as well as a police control post whose function is to monitor the country's border, to safeguard the security of the country, and to prevent crime.
