Shide (紙垂, 四手) are zigzag-shaped paper streamers, often seen attached to shimenawa or tamagushi to demarcate holy spaces, and used in Shinto rituals in Japan.^[1][2] They are usually found adorning doorways, shrine buildings, and kamidana.

The origins of shide are traced to the yūshide, a thread made from the bark of Broussonetia x kazinoki mentioned in the Kojiki. There are different styles of folding shide. One method requires placing the paper zigzags in a cut slit on a stick, creating a ritual object known as a gohei or heihaku.^[3] A gohei is an offering to kami that can be seen on kamidana altars and inside the main building of a Shinto shrine.^[4]

A common purification ritual uses a haraegushi, a wooden stick with linen or paper shide attached at the top.^[5] A Shinto priest waves the haraigushi over a person, item, or newly bought property, such as a building or a car. The wand is waved at a slow and rhythmic pace, but with a little force so that the shide strips make a rustling noise on each pass of the wand. For new properties, a similar ritual known as jichiin sai (lit. "calming the land") is performed with a haraigushi within an enclosed part of the land (enclosed by shimenawa).
