Hashira

Hashira (柱) is the Japanese word for a pillar. The dictionary Daijisen defines it as a member set upright on the ground, a foundation stone or a sill, which carries the load of the roof, beams and floors above. Shibari Study notes that the word refers to the vertical wooden beams of a traditional Japanese house and carries no bondage meaning by itself; Rope365 lists hashira as the pillar tie, tying someone to a vertical post.

What it is

Kinbakuwiki, a German-language community wiki, treats hashira shibari (柱縛り) as a whole group of rope patterns made on an upright pillar or beam rather than a single tie. Most combine an upper-body tie with a hip or thigh harness, and many poses become possible once the anchoring on the post is solid; its gallery includes both upright hashira tsuri and inverted forms. The aim, according to the wiki, is to evoke a traditional farmhouse (minka) with its exposed timber frame.

Variations by teacher and school

Osada-ryū: Kinbakuwiki says the school often combines a simple thigh or hip harness with upper-body ties such as takate kote or kamakiri shibari, and that all the common schools practise hashira in a similar sequence.
ShibariClasses, taught by Bruce Esinem and Nina Russ: Part VII of its suspension series builds on Nina’s hip harness and a gote, and adds a simple variation of the harness that the teachers say makes it more comfortable and lowers the load on the gote. The course lists a partial suspension, a running man or postman version and an agura suspension among its variations.
The January 2026 weekend listed by Discover Kinbaku presents hashira as a way to work beyond bamboo with beams and poles. Its content list includes upright positions, tying with the arms around the pole and adapting the gote, and it names exposure, objectification and predicaments among the themes.
Andy Buru writes that a hashira or bamboo allows the body to spread in more directions, which can reduce the load on individual body parts compared with a single suspension point. Buru also writes that force concentrates on a vertical post, hard wood does not adapt to the body, and entering and leaving the tie is slow.
Red Sabbath, in a 2015 Kinbaku Today article, writes that on a hashira the post limits movement and reduces rib-cage expansion in a way a beam or bamboo does not, and describes this as the main difference from other suspensions.

History and lineages

ShibariClasses, whose main teachers are Bruce Esinem and Nina Russ, calls tying on a post a classic method, especially among people who tie in an old-school style, because the wooden beams of old Japanese houses were always at hand. A listing for a January 2026 hashira weekend presents the upright pole as kinbaku at its oldest and most elemental, a setting for ties meant to leave the person feeling exposed and vulnerable. Kinbakuwiki says the major schools all practice it in a similar sequence; in Osada-ryū it is taught only in the second third of the curriculum, often as a simple thigh or hip harness combined with an upper-body tie such as the takate kote.

ShibariClasses names Yukimura Haruki, Nureki Chimuo and Marai Masato as examples of people who tie in the old-school style that uses the post. Red Sabbath, in a 2015 Kinbaku Today article, describes hashira shibari as especially typical in Japan and says it was experienced in lessons with Naka Akira at Studio6. Andy Buru writes that learning to tie from a single point later led to using a horizontal beam, and interprets bondage photographs from the 1940s and 1950s as showing the hashira as the standard suspension setting. Buru guesses that old Japanese houses had few ceiling suspension points and many supporting pillars; ShibariClasses likewise points to the ready availability of wooden beams.

Difficulty and risk

Sources agree that the suspended form is advanced. ShibariClasses ties that rating to the challenge of making secure anchors on a vertical post, and Kinbakuwiki places hashira patterns in the advanced range. The wiki also says that the technical demands make it hard to keep up communication with the partner, that coming down takes longer because the ropes have to be removed first, and that sensations for the person tied can be very intense. Kinbaku World describes these forms for understanding only.
