Kameido, in Northern Koto-ku, was the name of Edo's northeasternmost district. The other were Nihombashi, Kyobashi (including Ginza and Tsukiji), Kanda and Fukagawa.
Notwithstanding its not so central location, Kameido is still shitamachi, and as such is endowed with plenty of temples and shrines.
Kameido Tenjin Shrine 亀戸天神社
The area's main sight is the Kameido Tenjinsha Shrine, famous for its arched "drum bridge" and wisteria. The shrine was established in 1662 in honour to the politician, scholar and poet Sugawara no Michizane. The legend has it that when Michizane was exiled to Kyūshū and died soon afterwards, some natural disasters struck Kyoto and were believed to be his vengeful spririt. Michizane was later associated with the Thunder God, then the God of Literature and Learning.
