Joan Jett has said she has eight tattoos, with pieces on her neck, hip, lower back, arms and ankle. Photographs clearly show the sternum V, forearm spiral, upper-arm band, lower-back labrys and Om at her nape; the smaller pieces in her count are less consistently pictured.
Jett has explained the meaning of several designs herself. She connects the V with divinity, the spiral with consciousness and possibility, and describes the upper-arm piece as a figure-eight band with a triangle and loops. The photographs show their placement and shape, while her comments add context.
Joan Jett’s sternum V symbol

The small grey-black design sits along the centre of her chest. Its pointed V opens into curling lines at the top, with a diamond-like detail inside. Jett said she chose it as a reminder that divinity exists in everyone, describing the shape as an old sign associated with figures representing the divine.
Joan Jett’s left forearm spiral

A spiral or oval sits at the centre of the left forearm design, ringed by short rays. Jett described the spiral as “un-manifest consciousness,” or consciousness at rest, and said the rays stand for possibilities. The abstract mark is visible in performance photos when she turns her arm toward the guitar.
Joan Jett’s looping upper-arm armband

Jett has described this band around her left upper arm as a figure eight with a triangle and more loops above it. In photographs, the open loops wrap around the bicep; they narrow and overlap as the arm turns, rather than forming a solid black strip.
Joan Jett’s lower-back labrys design

The symmetrical lower-back emblem shows two crossed, double-edged blades surrounded by flame-like lines. Steal Her Style identifies them as Greek labryses and notes that the crosses at the handles and surrounding outline echo female symbols. The photo makes the crossed blades and balanced layout clear, even where no single caption settles the design’s full meaning.
Joan Jett’s chest symbol in an older portrait

An older portrait shows the same V between Jett’s jewellery and neckline. The point faces down, and the upper curls remain visible above the clothing. It offers a second view of the sternum tattoo, not a separate design.
Joan Jett’s neck Om tattoo

The small Om mark sits at the nape just below the hairline. Hair or a high collar can hide it, so it is less visible in many concert photographs. Its placement adds a compact symbol to the better-documented chest, arm and back tattoos.
Several pieces share one visual rhythm
Curves link the sternum V, forearm spiral, armband and Om, while the labrys adds the sharper lines of crossed blades. Shape and placement make each piece legible; the designs remain separate rather than forming a single sleeve or panel.
Jett’s own count leaves part of the record private
Jett has referred to eight tattoos and mentioned her neck, hip, lower back, arms and ankle. The photographs here show the sternum, arm, lower-back and nape designs, but not an equally clear close-up of every piece in that count. Clothing, hair and camera angles limit what can be confirmed from photos.
