History
The name "Ryūgasaki" can be traced back to 1182 when the samurai clan ruling the territory adopted "Ryūgasaki" as their family name. The northern half of the city was an exclave of Sendai Domain during the Edo period, the region joined Miyazaku Prefecture in 1869 before merging with Ibaraki Prefecture in 1875. The southern portion of the city was part of Kitasōma District in Shimōsa Province, as the boundary between Shimōsa and Hitachi Province had been established in the Nara period as the Tone River. However, by the Meiji period, the course of the river had shifted, leaving the area of present-day southern Ryūgasaki on the northern bank of the river. This area was transferred to Ibaraki Prefecture in 1875
The town of Ryūgasaki was created with the establishment of the modern municipalities system on April 1, 1889.
The city was formed on March 20, 1954, when the aforementioned town merged with: Nareshiba, Ōmiya, Yabara, Nagato, Kawarashiro and Kitamonma. In February 1955, the city grew to its present size when a proportion of Takasu merged with the city.[5]
In 1974, the city adopted the Swan, the Pinus, and Platycodon grandiflorus as its city symbols for bird, tree and flower respectively.[6]
