Yoroi-jinja, Shinto shrine in Japan
Yoroi-jinja is a small Shinto shrine in Shinjuku with a simple wooden structure and traditional roof. The well-kept grounds contain stone lanterns, small statues, and several subsidiary shrines, including Tenjin-sha dedicated to the god of learning.
This shrine was founded over a thousand years ago during Emperor Daigo's reign when the monk Jōsū built it to protect the nearby Enshō-ji Temple. Its history is linked to the warrior Taira no Masakado, whose armor is said by legend to be buried here.
The name Yoroi refers to armor and connects this place to legends of the samurai Taira no Masakado. Visitors come here to offer prayers for protection and to pay respect, showing how local traditions and ancient warrior stories remain alive in daily life today.
The shrine is easily accessible on foot from nearby train stations and sits in a lively area with shops close by. The compact grounds are easy to navigate, allowing for a quick visit, especially on weekdays when it is quieter.
An old tree called the Helmet Tree marks the spot where the helmet of Taira no Masakado is said by legend to be buried. After World War II, this warrior's spirit was moved back to the main hall at the request of local residents.
