修行会

Musubi—often translated as “binding” or “creative joining”—is a core Shintō idea that first appears in Japan’s earliest chronicles, the Kojiki (712) and Nihon Shoki (720), where deities named for musubi help bring the world into being. In everyday religious life, that invisible power is made visible through two simple materials: the straw rope called shimenawa, which marks off sacred ground, and the white zig‑zag paper strips called shide, which signal purity and flutter on shrine gates, sacred trees, and ritual wands. Together they show where the sacred begins, guide people across thresholds, and remind communities that creation and care are ongoing acts—something you can see, touch, and even hear rustle in the breeze. We‘ll go over the meanings specifically, where the ideas come from, what these do, review a timeline from ancient times to date, and mix in a little Morihei Ueshiba, who composed Classical Japanese poetry (waka) reinvigorating musubi etc., then a review, and close.

What do these words mean?

Musubi (むすび). “Tying” or “bringing together.” In Shinto thought, it’s the creative force that connects heaven, earth, nature, and people. Some early kami even have musubi in their names, like Takamimusubi and Kamimusubi (Breen & Teeuwen, 2010; Hardacre, 2017; Kokugakuin University, n.d.).

Shimenawa (しめなわ). A thick straw rope you see at shrines, around sacred trees, or across gates. It marks a boundary so you know, “This space is special.”

Shide (しで). White zig‑zag paper (sometimes cloth) hung from the rope or a wooden wand. When a priest waves a wand with shide, it’s used for purification.

Think of shimenawa as a visible “do not cross” line for everyday dirt and bad luck, and shide as the “cleaning motion” that helps restore purity.

Where do these ideas come from?

The Kojiki (compiled 712 CE) and the Nihon Shoki/Nihongi (720 CE) name musubi deities who help the world come into being (Philippi, 1968/2015; Aston, 1896/2010).

A famous myth tells how the Sun Goddess hides in a cave, making the world dark. People lure her back out with dance (think festival [matsuri]). Many later stories connect shimenawa to this scene to keep the cave from being closed again—symbolizing that ropes can “hold” the world open to light (Bocking, 2005; Kokugakuin University, n.d.).

What do shimenawa and shide actually do?

Mark sacred space. Hanging a rope across a gate or around a tree says, “The kami (divine presence) can be here.” It’s like building a mini‑shrine without walls (Kokugakuin University, n.d.).

Create a clean boundary. In Shinto, purity matters. The rope shows where special care begins and helps separate everyday mess from ritual space.

Support purification. Priests use shide on a wand (called gohei) to sweep away defilement (harae). The crisp motion and rustle make the action feel real (Kokugakuin University, n.d.).

Travel beyond shrines. The grand champion in sumo (the yokozuna) wears a belt styled like shimenawa with shide, turning his body into a moving sign of strength and sacred order (Kokugakuin University, n.d.).

From ancient times to today, a timeline

Ancient (700s). Kojiki and Nihon Shoki describe a world shaped by musubi. Ritual spaces, cords, and wands express this idea in practice (Philippi, 1968/2015; Aston, 1896/2010).

Medieval. Shrines and Buddhist temples often worked together. Ropes, banners, and sacred objects crossed those boundaries, showing a mixed religious world (Breen & Teeuwen, 2010).

Early modern (Edo). Thinkers re-read the classics and highlighted “native” ideas, giving musubi fresh attention (Breen & Teeuwen, 2010; Bocking, 2005).

Modern (Meiji to now). The government reorganized religion and shrines. After World War II, many practices continued in everyday culture and as heritage. Japan’s Agency for Cultural Affairs helps protect crafts, buildings, and traditions related to shrines (Agency for Cultural Affairs, 2022; Hardacre, 2017).

Aikido and O‑Sensei’s poems: a modern voice for musubi

Morihei Ueshiba (founder of Aikido) wrote short poems (dōka) that talk about musubi in simple, powerful images. Here are four common themes—paraphrased instead of quoted:

“Musubi Bound Accord” (No. 149). Heaven, earth, kami, and people are tied into harmony—our job is to protect that bond (cf. Ueshiba, 1977/2025d).

“Pine, Bamboo, & Plum” (No. 134). These “three friends of winter” symbolize toughness and renewal; training joins “fire” and “water” inside us—another kind of musubi (cf. Ueshiba, 1977/2025b).

“The Rock‑Door Again Opened” (No. 132). Awakening means reopening the door from darkness to light—like the myth, but inside the heart (cf. Ueshiba, 1977/2025a).

“Takemusu’s Fire–Water Springs” (No. 142). True martial creativity (takemusu) rises from orthogonal awareness with inhalation-exhalation (i.e., breathing; cf. Ueshiba, 1977/2025c).

Why it matters

Big idea, small tools. A thick straw rope and a paper zig‑zag make an invisible idea—musubi—easy to see and feel.

Belief you can touch. Crossing under a rope, seeing shide flutter, or hearing them rustle turns belief into experience.

Living tradition. From classic books to modern festivals (and even sumo), these items keep reminding people where the sacred begins and how to care for it.

Mini-glossary

Kami. Divine beings or sacred presence in Shinto.

Harae / Misogi. Purification rites; misogi often involves water.

Gohei. A wooden wand with shide attached, used in rites.

Himorogi. A simple, temporary sacred space—often four posts and a shimenawa.

Discussion

Across history, shimenawa and shide have served as tools for drawing boundaries and restoring balance. Hung across torii gates or around old trees, a rope says, “treat this carefully”; attached to a gohei wand, shide help priests enact purification through a sweeping motion. The same vocabulary shows up in festivals that string temporary sacred spaces (himorogi), in the yokozuna’s braided belt that turns the sumō champion into a moving threshold, and in modern cultural‑heritage work that preserves shrine crafts and techniques. Read alongside the classics, these practices suggest that musubi is not just a belief about how the cosmos began—it’s a habit of tying things together now: people to place, communities to seasons, and intention to action.

Coda

Musubi is the knot you can actually tie. Morihei Ueshiba’s poems commonly linked to this theme (e.g., the “rock‑door” opening, the balance of fire and water, the accord of heaven–earth–human, and the wellspring of takemusu creativity) point to practice: breathe, align, and bind yourself to what should endure. The next time you pass under a rope or notice shide move, treat it as a reminder to reopen the “door” to clarity, to keep your promises, and to guard the accord you share with others.
