"Shiogama" means "salt furnace" and refers to a local Shinto ritual involving the making of salt from sea water, still performed every July. The name is sometimes written using the kanji å¡©é rather than å¡©ç« and both spellings are officially permitted. Both é and ç« are pronounced gama in compounds, but as lone words they are pronounced kama and kamado, respectively. A ' (ç«Â, "furnace") is what a ' (éÂÂ, "kettle") is placed upon, and so the two are not completely interchangeable. å¡©ç« is the form officially used by the city, but for ease of writing, the 10-stroke é is often used in place of the 21-stroke ç«Â, such as in Shiogama Station.
Shiogama Jinja uses the rendering é¹½ç«Â, with an archaic character for salt. This third form is rarely seen outside of this context.
The area of present-day Shiogama was part of ancient Mutsu Province, and has been settled since at least the Jà Âmon period by the Emishi people. During the Nara period, the area came under the control of colonists from the imperial dynasty based at nearby Tagajà  and was the most important seaport in Mutsu. The ruins of the provincial capital of Mutsu Province have been found within the city borders. During later portion of the Heian period, the area was ruled by the Northern Fujiwara. During the Sengoku period, the area was contested by various samurai clans before the area came under the control of the Date clan of Sendai Domain during the Edo period, under the Tokugawa shogunate.
