Asakusa Shrine (浅草神社, Asakusa-jinja^?), also known as Sanja-sama ("Shrine of the Three Gods"), is one of the most famous Shinto shrines in Tokyo, Japan. Located in Asakusa, the shrine honors the three men who founded the Sensō-ji. Asakusa Shrine is part of a larger grouping of sacred buildings in the area. It can be found on the east side of the Sensō-ji down a street marked by a large stone torii.

An example of the gongen-zukuri style of architecture, Asakusa Shrine was commissioned by Tokugawa Iemitsu and constructed in 1649 during Japan's Edo Period. It was constructed in order to honor the three men who established and constructed the Sensō-ji. The legend states that two brothers, fishermen named Hinokuma Hamanari and Hinokuma Takenari, found a bosatsu Kannon statuette caught in a fishing-net in the Sumida River on May 17, 628.

The third man, a wealthy landlord named Hajino Nakatomo, heard about the discovery and approached the brothers to whom he delivered an impassioned sermon about the Buddha. The brothers were very impressed and subsequently converted to the Buddhist religion. The Kannon statue was consecrated in a small temple by the landlord and the brothers who thereafter devoted their lives to preaching the way of Buddhism. This temple is now known as the Sensō-ji. Asakusa Shrine was built in order to worship these men as deities. The shrine and its surrounding area and buildings have also been the site of many Shinto and Buddhist festivals for centuries. The most important and famous of these festivals is Sanja Matsuri, held in late May.

Asakusa (浅草^?) is a district in Taitō, Tokyo, Japan, most famous for the Sensō-ji, a Buddhist temple dedicated to the bodhisattva Kannon. There are several other temples in Asakusa, as well as various festivals.

For most of the twentieth century, Asakusa was the major entertainment district in Tokyo. The Rokku or "Sixth District" was in particular famous as a theater district, featuring famous cinemas such as the Denkikan. The golden years of Asakusa are vividly portrayed in Yasunari Kawabata's novel The Scarlet Gang of Asakusa (1930; English translation, 2005). The area was heavily damaged by US bombing raids during World War II, particularly the March 1945 firebombing of Tokyo. The area was rebuilt after the war, but has now been surpassed by Shinjuku and other colorful areas in the city, in its role as a pleasure district.

Asakusa is on the north-east fringe of central Tokyo, at the eastern end of the Ginza subway line, approximately one mile east of the major Ueno railway/subway interchange. It is central to the area colloquially referred to as Shitamachi, which literally means "low city," referring to the low elevation of this old part of Tokyo, on the banks of the Sumida River. As the name suggests, the area has a more traditionally Japanese atmosphere than some other neighborhoods in Tokyo do.
