Shinju

Shinju (from the Japanese (真珠) meaning pearl) is a word used euphemistically in Japanese to refer to the female breast. It is also popularly used as the name of a type of female halter top in the clothing industry.

It has been popularly claimed that "shinju" is an authentic Japanese term for a breast bondage tie. The tie is usually shown to be something similar to what in the west bondage is called a "bikini harness". There is however, no such tie called a "shinju" found in historic or present "Kinbaku" (Japanese Bondage). The word was erroneously applied to Japanese Rope Bondage in Europe in the mid-1990s by commercial websites.

The basic or foundational Kinbaku form of binding the arms and breasts is known as the "Ushiro Takate-kote"; which is to bind the arms behind (ushiro) the back in a box arm position (takate-kote). This basic box arm tie originally found in the samurai martial art of Hojōjutsu (捕縄術) or Nawajutsu, (縄術) evolved into its erotic usage at the end of the 19th century and early 20th century and is foundational to most other Kinbaku ties.

Technique

In shibari, a shinju is a basic chest harness. It will support the breasts and can be used as a harness which can be used as anchor points for any number of other restraints.

  1. Using a forty-foot piece of rope, fold it in half. This center point is referred to as the "bight". Place the bight near the center of the back and wrap it horizontally around the body, across the bottom of the breasts, and back around to the bight in the back. Pull the ends of the rope through the bight to create a larks head, making the bottom of the bottom band
  2. Pull the rope snugly and make sure is up against the bottom of the chest, and wrap the rope around right above the last band of rope back around to the larks head just created. This will be the top of the bottom and will push up and lift the chest a little. Pull the ends through the last lark's head you made to create a 2nd larks head.
  3. Pull the rope snug and wrap around the body in the opposite directions, this time on the time of the chest, back around to the lark's heads (this will make the top of the top band.
  4. Pull the ends snugly through the 3rd larks head you created, to make the last of the bands. Fold the rope and go back around, to make the bottom of the top band. And end up at all the series of larks heads on the back.
  5. You can create a half hitch or square knot here to tie off the banding part of the shin-ju. For more advanced you can just pull the ends through one of the lark's heads, which I usually pick the lowest one, to help support the chest harness up higher, and pull the tails through snugly.
  6. Take the tails up and over one shoulder, and down between the breasts to make a strap. Pull the ends under both the upper and lower bands of rope. If the tails are not long enough to complete this, see Alternative 1 below.
  7. Take the ends up the front of the lower band, and twist the rope 1 or 2 times around the strap coming down and up on the outside of the upper band and up and over the opposite shoulder.
  8. Bring the ends down to the series of larks heads and loop the tails through one of the lark's heads and you can create a half hitch or larks head here to tie it off. Personally, I like to fold the rope back up, and create a bar wrap by just twisting the rope around both bra straps till out of rope, and finish it off with a square knot.

Alternate ideas

  1. If you do not have enough rope to go down and back up to make the bra straps, you can spilt the two pieces of folded rope, and put on over each shoulder, down between the breasts, under both fold and then up and bring the ends behind the straps you just made and tie a square knot to finish it off.
  2. If doing a bar wrap up the back to finish it off. If a girl has long hair, down to her mid-back or butt. You can do the bar wrap around the strap and the hair all at once to create a hair bondage scenario all at the same time.
  3. Apply the bands of rope so that they push up from the bottom and down from the top. This pressure on the top and bottom of the chest makes the nipples more sensitive, all the better for sensation and torture play.
  4. After you learn the basic concepts down for the chest harness, you can be creative and artistic.

There are so many, many knots available to us all. There are three specific knots that I will talk about here.


This knot can tie two ropes or two ends of a rope together.

The name of the game is "Bondage and Discipline", not "Cuffs and Discipline". Bondage is an elemental part of B&D sessions. If you are insecure about your knot-tying abilities, your client will definitely notice it.

These three knots above should be considered 'bare minimum requirements' for anyone wishing to do sessions. For safety reasons, you should also be able to tie and untie them in the dark.
