[1] History of Myinmu is closely linked to the World War II against the Japanese Army when British General Sir Douglas Gracey occupied the town after crossing the Irrawaddy River.

Other settlements of note in the township are Allagappa to the west, Tizaung to the northeast and Ngaizun several miles away on the opposite side of the river from the main town.

[5][6] Myingu township was occupied by Portuguese missionaries in the late 19th century who established Roman Catholic mission stations at Nabet and Chaungu.

Jowar (locally in Burmese language “pyaung”), called the great millet was grown in the dry zones of Singiang District, which was the staple food of people in Myinmu and Myotha towns.

[11] The agricultural economy of the township got a boost with assistance provided by the Japan International Cooperation Agency (JICA) to rear pigs and grow mushrooms under a cooperative pilot project launched by the Ministry of Livestock and Fisheries, the Ministry of Cooperatives and the Ministry of Agriculture and Irrigation, as a poverty alleviation programme in the dry zone under a development study on sustainable agriculture and rural development.
