Shiogama's name means "salt cauldron", and this refers to an ancient Shinto ritual involving the making of salt from sea water that is still performed every July at the Okama Jinja Shrine.
Accordingly, Shiogama is also famous for its seafood, especially its sushi - the city boasts the most sushi restaurants per square kilometer of any city in the country.
The city is also home to one of the most important Shinto shrines in Tohoku, Shiogama Jinja, which is accessible up a rather tiring flight of 201 steps and has an interesting museum on the feudal and economic history of the city, including some fascinating exhibits relating to whaling.
