Welcome to Hikawa-jinja, written 氷川神社 in Japanese, in the Akasaka district of Minato City, Tokyo. This is the Akasaka Hikawa shrine, one of the 10 shrines of Tokyo. The name is shared by several shrines around Minato City, so it helps to know you are standing at the Akasaka one. This guide stays with the essentials: when the shrine was founded, who ordered the present building, and why that building is so unusual in a city that has been rebuilt so many times. At the end we will step briefly into the neighborhood to meet two other Hikawa shrines nearby in Minato City, so you can tell them apart. Take a slow breath before you go further. You are in the middle of a modern capital, standing at a place with roots reaching back more than a thousand years.
