The jo and hanbo

The jo (杖) and hanbo (半棒) are the close-range members of the Japanese stave family. Where the bo is six feet long and works at long range, the jo at four feet works at the medium range that brings the user inside sword-distance, and the hanbo at three feet works at the short range that overlaps with empty-hand grappling. Both staves are predominantly white oak (kashi), both are produced to formal specifications, and both sit within a substantial body of surviving classical Japanese martial-arts practice.

This reference page covers them together because their craft and material context is shared, and because the two are often taught together in classical lineages. The jo gets the larger share of the page — there is more documented surviving practice — but the hanbo is treated thoroughly enough that a reader can place it in the broader Japanese stave world.

The jo

Origin

The jo’s origin is unusually well-documented in Japanese martial-arts history. The classical lineage descends from Musō Gonnosuke Katsukichi, a samurai of the early Edo period (early 1600s), who is reported to have developed the jo as a counter-weapon to the sword after losing a duel to Miyamoto Musashi. The story is partly legendary and partly historical; what is confidently documented is that Musō Gonnosuke established the Shintō Musō-ryū lineage, which has preserved the original jo curriculum continuously to the present day.

The Shintō Musō-ryū jo curriculum is, in its surviving form, a system of 64 paired kata (training patterns) executed by two practitioners — one with a sword (the uchidachi, the “striking sword”), the other with a jo (the shidachi, the “executing stick”). The jo’s technical advantages over the sword are its two-ended use (the sword has an edge only on one side; the jo strikes with both ends), its superior reach in some applications (the four-foot jo is longer than a katana), and its versatility in striking, thrusting, and locking techniques.

Formal dimensions

The standard jo specification is 4 shaku, 2 sun, 1 bu — about 1.28 metres or 50.5 inches. The diameter is approximately 8 bu (~24 mm) at the centre, slightly tapered toward the ends. Some lineages outside the Shintō Musō-ryū main line use slightly different specifications; the All Japan Kendo Federation’s Jodo division (the modern competitive jodo organisation) has standardised dimensions for tournament use.

A working jo from a Miyakonojō white-oak workshop conforms to within a few millimetres of these specifications. The piece is straight, balanced at the centre, and uniform in cross-section; quality control at the workshop level enforces the conformance.

The modern practice

Jodo today exists in three overlapping streams:

The classical Shintō Musō-ryū lineage, with surviving teaching lines descended from Shimizu Takaji (the early-twentieth-century master who brought the art into modern public teaching) and now spread across Japan and internationally. Practising students are typically members of formal koryu lineages with their own grading systems and lineage politics.

The Seitei Jodo (制定杖道) curriculum — the standardised modern jodo developed by the All Japan Kendo Federation, drawing on Shintō Musō-ryū kata in modified form. Seitei Jodo is more accessible to ordinary practitioners (typically taught in kendo dojos that offer jodo as a sister art), is graded through the same kyu/dan system as kendo, and is the form in which most non-Japanese students first encounter jodo.

The aikido jo — the jo work taught in aikido as part of the broader weapons curriculum (alongside bokken, tanto, and the empty-hand throwing art). Aikido jo is shorter and more focused than classical jodo, but uses the same physical equipment and shares some technical principles. Major aikido organisations (Aikikai, Iwama Ryu, Yoshinkan) each have their own jo curricula.

A new student approaching the jo in 2026 most commonly encounters Seitei Jodo first (through a kendo dojo) or aikido jo (through an aikido dojo). Classical Shintō Musō-ryū requires more deliberate seeking-out and admission to a recognised lineage, but is genuinely accessible to committed students.

The hanbo

Origin and use

The hanbo (半棒, “half-staff”) is the three-foot stave — half the length of a bo, somewhat shorter than a standard walking stick. Its origin is less centralised than the jo’s; the form appears in several classical Japanese martial-arts lineages without a single Musō Gonnosuke equivalent.

The hanbo’s working role is close-range combat — distances at which the longer jo and bo become unwieldy. The form is held in one or two hands depending on technique; it serves both as a striking weapon (with both ends used) and as a leverage tool for joint locks and throws.

Where the hanbo appears

In classical jujutsu lineages, the hanbo appears as a weapons element alongside swords, daggers, and other weapons. The Yagyū Shingan-ryū and several other surviving koryu schools include hanbo curricula.

In aikido — particularly the Iwama Ryu and some other lineages — the hanbo is taught as a sister weapon to the jo, with techniques that emphasise the close-range applications.

In ninjutsu — particularly the Bujinkan organisation founded by Masaaki Hatsumi — the hanbo is a central weapon in the Hanbojutsu curriculum. The Bujinkan tradition places more emphasis on the hanbo specifically than most other Japanese martial-arts organisations.

In some modern police and security training contexts, particularly in Japan, hanbo techniques are taught as a non-lethal subduing-and-control method. The form is short enough to be carried discreetly and useful enough at close range to provide a real defensive option.

Material and dimensions

The hanbo is, in materials and construction, identical to the jo at smaller scale. White oak is the dominant material; American hickory is the Western alternative; bamboo is occasionally used for partner practice. The standard length is 3 shaku (about 91 cm / 36”), with diameter approximately 22–24 mm.

Working hanbo from major Japanese workshops are typically lower-priced than jo from the same workshop simply because there is less material involved — typically ¥4,000–¥10,000 for a working-grade Miyakonojō piece (~$30–$70 USD).

How the two staves are made

The production process for jo and hanbo follows the same workflow as for the bo, scaled down for the shorter pieces:

Selection of the billet — straight-grained, knot-free white-oak (or alternative) billets, kiln-dried to working moisture content, of cross-section appropriate to the finished diameter.

Turning — the billet is mounted in a wood-turning lathe and shaped to a cylinder of the final diameter, with slight tapering at the ends.

Smoothing and finishing — the shaped cylinder is sanded through several grit stages and finished with linseed oil or similar penetrating oil. Burnt finish (yakikomi) is occasionally applied to jo and hanbo as well as to bo.

Quality control — straightness, balance, weight, and dimensional conformance are checked. Pieces that fail are downgraded.

Marking and packaging — the maker’s mark is applied; the piece is packaged for shipping.

The whole process per piece runs a few hours of bench-time at a working workshop volume; a Miyakonojō workshop produces many hundreds of jo and hanbo per month for the global martial-arts equipment market.

Buying a jo or hanbo

The same supply-chain considerations apply as for the bo. Working-grade pieces are widely available; Miyakonojō white-oak pieces are the recognised gold standard; American hickory alternatives are less expensive and broadly comparable in working performance.

For a Seitei Jodo student or aikido student, a working-grade white-oak or hickory jo from a reputable martial-arts supplier is appropriate; expect to spend $50–$150 for a quality working piece.

For a Shintō Musō-ryū student or a serious classical practitioner, the dojo or sensei will typically have specific recommendations on the equipment grade and supplier; expect to be guided to higher-grade pieces ($150–$300+).

For a hanbo specifically — used in fewer contexts than the jo — the supply is thinner but several major suppliers carry working-grade pieces. Expect $40–$100 for working-grade white-oak or hickory.

The journal does not currently maintain a recommended-suppliers list for Japanese martial-arts equipment; reader contributions on reliable workshops are particularly welcome.

The relationship to the bo

The bo, jo, and hanbo form a recognisable family of Japanese training weapons sized for different ranges:

• Bo (6 feet) — long range, two-handed grip, broadly equivalent to a polearm
• Jo (4 feet) — medium range, two-handed grip, broadly equivalent to a quarterstaff
• Hanbo (3 feet) — close range, one or two-handed grip, broadly equivalent to a fighting stick

The three are typically taught in different martial-arts contexts and by different lineages. A student of bojutsu is not automatically a student of jodo or hanbojutsu; conversely, a student of one of the shorter staves is not necessarily a bo student. The cross-traffic exists — particularly in aikido, where all three weapons appear in some curricula — but the deeper traditions tend to specialise.

The full side-by-side, with technical comparisons and lineage notes, is at Bo vs jo vs hanbo.

Pascal Krieger and the documentation question

The single most useful English-language reference on the jo is Pascal Krieger’s Jodo: The Way of the Stick (1989) — Krieger is a senior Shintō Musō-ryū practitioner based in Switzerland whose book documents the classical curriculum, the historical lineage, and the technical principles in considerably more detail than any other English-language source. The book is out of print but available through second-hand specialist booksellers and through some martial-arts library systems.

For the hanbo, English-language documentation is thinner. Donn F. Draeger’s broader survey works on classical Japanese martial arts (the Martial Arts and Ways of Japan series) cover the hanbo in passing; specific hanbo curricula are typically transmitted through dojo-based teaching rather than through published references.

A reader who wants to study these weapons seriously is best served by finding a working dojo with a recognised lineage; written references are useful as supplements but are not substitutes for direct teaching.
