Krav Maga vs. Ninjutsu
Quick answer
Krav Maga and Ninjutsu have no common root. Krav Maga is an Israeli self-defence system with strikes, kicks and stress drills, while ninjutsu is taught by the Japanese organizations Bujinkan, Genbukan and Jinenkan through paired kata, controlled randori and work with weapons. Neither has a sport competition, and the documentation of the ninjutsu lineage back to the historical shinobi is disputed.

History and relationship
Krav Maga and Ninjutsu have no common root, and we did not find a source that would compare them directly. Krav Maga was put together by Imi Lichtenfeld from European boxing, wrestling and street fighting, and from 1944 he taught it in the Hagana. Present-day ninjutsu is taught by the Japanese organizations Bujinkan, Genbukan and Jinenkan, which claim descent from the historical shinobi of the Iga and Koga (Koka) regions.
The documentation of the ninjutsu lineage is disputed. The historian Stephen Turnbull (2014) writes that Iga “created a tradition” for itself, and the dictionary Bugei Ryuha Daijiten describes the Togakure-ryu genealogy as embellished. Hatsumi’s certificate from 1958 for the title of 34th grandmaster of Togakure-ryu is not supported by records of earlier holders. The Iga-ryu Ninja Museum regards Jinichi Kawakami as the legitimate heir, which contradicts Hatsumi’s position.
- 1574 and 1581: Oda Nobunaga subdued Koga and the province of Iga.
- 1655 to 1681: the shinobi writings Ninpiden, Bansenshukai (sources give 1675 or 1676) and Shoninki.
- 1948: Imi Lichtenfeld becomes chief instructor of physical training and Krav Maga in the new Israeli army.
- Around 1972: Masaaki Hatsumi founded the Bujinkan, Shoto Tanemura the Genbukan in 1984 and Fumio Manaka the Jinenkan in 1996.
- 1995 or 1996: the IKMF comes into being, and after Lichtenfeld’s death in 1998 several of his students claimed the succession.
Technique
- Punches, forearm and hammer strikes, elbows, knees and kicks.
- Targets such as the eyes, throat, groin, ribs, knee and liver.
- 360-degree defence and defence against a knife, a stick and a firearm.
- Locks and ground fighting, the share of time on the ground is not stated in the sources.
- The Bujinkan brings together nine ryuha, three based on the tactics of the ninja and six on the tactics of the samurai.
- In taijutsu the defender intervenes, locks, chokes and throws.
- Weapons in the curriculum: swords, staffs, spears and naginata, each year a different theme.
- The Genbukan teaches, among other things, bojutsu, kusarigama and shuriken.
Krav Maga rests on principles instead of fixed techniques, on simple repeatable strikes and improvised objects, and it attacks until the opponent is unable to fight. Ninjutsu is learned ryuha by ryuha, for example Gyokko-ryu, Koto-ryu or Takagi Yoshin-ryu, and work with weapons belongs to regular training.
Training
| Krav Maga | Ninjutsu | |
|---|---|---|
| Pillars of teaching | stress drills, scenario training, sparring and slow-fight, ambush training in a protective suit | kata with the roles of tori and uke, henka variations, controlled randori |
| Partner’s resistance | in some organizations up to grade G2 slow and light sparring, then simulated fighting with protective gear | testing against full resistance depends on the instructor |
| Rules | self-defence without sporting rules, the limit is the law and proportionality (IKMF) | there is no official set of rules |
| Weapons | defence against a knife, a stick and a firearm | swords, staffs, spears and naginata according to the yearly theme |
In the Bujinkan, teaching moves from fixed kata through variations to free controlled work. We were not able to document the ratio of drilling to free work in a lesson for either of them.
Progression and ranks
| Krav Maga | Ninjutsu | |
|---|---|---|
| Ranks | IKMF: patches P1–P5, G1–G5, E1–E6 and Master, elsewhere judo-style belts and 1st to 9th dan | Bujinkan: 10th to 1st kyu, 1st to 10th dan, menkyo kaiden from 11th to 15th dan |
| Marking | IKMF has no belts, a patch on the trousers | in kyu a green belt for men and a red one for women |
| Special examination | transition from G5 to E1 only with the CIC instructor course | sakki test before the soke before 5th dan |
| Minimum times | IKMF Netherlands: at least 45 lessons to P1 and 65 to each further P grade | apart from the godan test there are no fixed criteria, the dojo determines progress |
In the Bujinkan the title of shidoshi is awarded from 5th dan, with which one may open a dojo and examine up to 4th dan. In the IKMF, P1, P3 and P5 are examined by one’s own instructor and the other grades centrally. The Genbukan and Jinenkan are separate organizations, and we did not find mutual recognition of ranks between the IKMF, KMG and IKMA.
Physical load and risks
- 946 training injuries of IDF soldiers (Farkash et al., Military Medicine 2017): mostly mild, most often fingers, hands and wrists (31%) and the shoulder (16%).
- A questionnaire of 109 practitioners (Yaacobi et al., Cureus 2024): most often the lower limbs, sprains and ligament tears 32.1%, fractures 22%, the data partly contradict each other.
- We did not find an injury study for ninjutsu, the Bujinkan or budo taijutsu.
- Bujinkan training is described as carrying a small risk of permanent injury, without figures.
Who it suits
| Krav Maga | Ninjutsu | |
|---|---|---|
| Professional groups | army and police alongside civilians, each group with a different focus | we were not able to document it |
| Women | IKMF Netherlands: the Stay Away course | we did not find a separate program, the Bujinkan distinguishes belt color in kyu |
| Older age | we did not find a program for seniors | we were not able to document it |
Children
| Krav Maga | Ninjutsu | |
|---|---|---|
| Age of programs | IKMF Netherlands: Kiddies ages 5–7, Kids 8–11, juniors 12–15 | we did not find children’s programs |
| Children’s training | the youngest play games without examinations, Kids have a partial examination every 2 months and K levels | we were not able to document it |
| Children’s competition | none | none |
| Studies | we did not find a study in children | we did not find a study in children |
Self-defence
- Verbal and physical de-escalation, attack only as a last resort.
- Defence against a knife, a stick, a firearm and multiple attackers.
- Stress drills and ambush training in a protective suit.
- Kata with fixed roles, then variations and controlled randori.
- The partner’s resistance depends on the instructor, there are no rules.
- The defender intervenes, locks, chokes and throws.
Krav Maga arose as a self-defence system for the army, and later Lichtenfeld adapted it for the police and civilians. Ninjutsu reaches defence through paired kata and randori. We did not find an independent source on effectiveness against a real attack for either of them.
Practical use
| Krav Maga | Ninjutsu | |
|---|---|---|
| Motor learning | 16 female university students (Di Bacco et al., PeerJ 2020): 15 minutes of instruction improved the straight punch and the defensive kick | we did not find a study with figures |
| Fitness | one lesson from a DVD with 16 people (University of Wisconsin-La Crosse for ACE): 78% of maximum heart rate, 8.8 MET | we did not find a study |
| Professional use | the Israeli army and police, since 2008 IKMF instructors at the German paratrooper school | we were not able to document it |
The Krav Maga studies work with small groups and a single lesson or short instruction. Nothing about ninjutsu can be inferred from them.
Competition
| Krav Maga | Ninjutsu | |
|---|---|---|
| Sport competition | none | none, the Bujinkan has no competitions or bouts |
| Other forms | the IDF has held an annual competition since 2013, rules not documented | we were not able to document it |
| Professional fights | Moti Horenstein lost at UFC 10 and UFC 14 | we were not able to document it |
Gear and costs
| Krav Maga | Ninjutsu | |
|---|---|---|
| Clothing | IKMF: grey T-shirt and black trousers with a patch, combat trousers not permitted | Bujinkan: black ninjutsugi, green or red belt |
| Footwear | indoor shoes | tabi in the dojo, jika-tabi outdoors |
| Equipment | mouthguard, shin guards, boxing or MMA gloves, groin protector | weapons according to the yearly theme, for example swords, staffs and spears |
| Relative cost | medium | medium |
Availability and organisations
| Krav Maga | Ninjutsu | |
|---|---|---|
| Organizations | IKMF, KMG, Krav Maga Worldwide, IKMA | Bujinkan, Genbukan, Jinenkan |
| Origin of the organizations | disputes over the succession after Lichtenfeld’s death in 1998 | Tanemura left Hatsumi after a disagreement, Manaka is cited as Hatsumi’s first student |
| Entry conditions | IKMF Netherlands: adults from age 16, elsewhere it states from age 18 | we did not find a source |
| Recognition of ranks | between organizations we were not able to document it | valid within the organization |
Philosophy
- Motto according to the IKMF: So that one may walk in peace.
- Avoiding violence, attack only as a last resort.
- Sakki test before 5th dan: sensing danger and avoiding it.
- We were not able to document a written philosophy of the modern organizations.
Forms and terminology
Krav Maga has no stylized forms, and techniques and scenarios are examined according to grade. Ninjutsu in the Bujinkan is based on kata with the fixed roles of tori and uke, and we did not find a list of named forms.
Training culture
- In the IKMF a rank patch on the trousers, elsewhere judo-style belts.
- A military and police branch alongside the civilian one.
- We were not able to document the salute and the form of addressing the instructor.
- The word ninja spread only in the mid-20th century, earlier shinobi, rappa or kusa were used.
- Mie University has had the International Ninja Research Center in Iga since 2017 and a master’s program since 2018 that, according to Professor Yuji Yamada, teaches about ninja but does not train ninja.
- In 2019 NHK reconstructed some of the kayakujutsu weapons from surviving manuals.
Common misconceptions
- The black clothing of the ninja: there is no hard evidence for it, it may have been an artistic convention, possibly borrowed from bunraku puppeteers.
- The human glider on a kite is called a fantasy by the historian Turnbull.
- According to the MythBusters test, the water shoes mizugumo are not suited to walking on water.
- The image of the silent killer dressed in black is mythologized, the word ninja spread only in the mid-20th century.
Which to choose
Frequently asked questions
Do Krav Maga and ninjutsu share a common origin?
No. Krav Maga comes from Lichtenfeld’s boxing and wrestling and from teaching in the Hagana and the Israeli army, while present-day ninjutsu is taught by Japanese organizations founded from 1972 onward. We did not find a source that would compare the two arts directly.
Is the ninjutsu lineage documented all the way back to the historical shinobi?
Sources differ. The Bujinkan lists Hatsumi as the 34th soke of Togakure-ryu, but according to the historian Turnbull, Iga “created a tradition” for itself, and the dictionary Bugei Ryuha Daijiten describes the genealogy of the school as embellished.
Is there competition in Krav Maga or in ninjutsu?
Neither has a sport competition. The IDF has held an annual Krav Maga competition since 2013, and we did not find its rules.
