Yakuza Vocabulary Explained: Japanese Gangster Words and Slang

Hello, I’m Kodak.

Yakuza movies, anime, manga, and video games are filled with words such as oyabun, kobun, aniki, wakagashira, sakazuki, gokudō, and katagi.

Before You Begin: “Yakuza Slang” Is Not One Standard Dictionary

There is no single vocabulary system shared identically by every organization, period, region, and fictional work.

For example, official titles may include 組長, 会長, 若頭, 理事長, 本部長, and other labels, but their exact authority is not automatically identical in every group.

Quick Yakuza Vocabulary List

1. やくざ / ヤクザ (Yakuza)

やくざ is the best-known everyday term. It may refer to a gangster, a member of a Japanese organized-crime group, or the underworld collectively.

彼はやくざではない。
Kare wa yakuza de wa nai.
He is not a yakuza member.

あんなやくざな商売には関わるな。
Anna yakuza na shōbai ni wa kakawaru na.
Do not get involved in such a disreputable business.

2. 暴力団 (Bōryokudan)

暴力団 literally combines violence and group. It is the formal term used in Japanese law, policing, government documents, and news reporting.

警察は暴力団の事務所を捜索した。
Keisatsu wa bōryokudan no jimusho o sōsaku shita.
The police searched the organized-crime group’s office.

暴力団 names the group. To describe an individual member, use 暴力団員 (bōryokudan-in).

3. 組 (Kumi)

組 is an ordinary Japanese word meaning a group, class, team, set, or association.

In an organized-crime context, it may mean a syndicate, family, group, or subgroup.

4. 組長 (Kumichō)

組長 literally means the head of a group.

彼はその組の組長だ。
Kare wa sono kumi no kumichō da.
He is the head of that group.

The term emphasizes a formal position. 親分, by contrast, emphasizes the personal relationship between a leader and followers.

5. 組員 (Kumiin)

組員 means a member of a 組. In news and crime contexts, it often means an organized-crime member.

複数の組員が逮捕された。
Fukusū no kumiin ga taiho sareta.
Several group members were arrested.

Because 組 can describe many kinds of groups, 組員 is not inherently criminal in every possible sentence. Modern news context, however, frequently uses it for a yakuza member.

6. 親分 (Oyabun)

親分 means boss, leader, protector, or a person treated as occupying a symbolic parent role.

The idealized relationship says that the oyabun protects and guides the followers, while the followers give loyalty and service.

親分は子分たちの面倒を見た。
Oyabun wa kobun-tachi no mendō o mita.
The oyabun looked after his followers.

7. 子分 (Kobun)

子分 means follower, underling, subordinate, or a person occupying the symbolic child role.

子分は親分の命令に従った。
Kobun wa oyabun no meirei ni shitagatta.
The kobun obeyed the oyabun’s order.

Henchman can work in a crime story, but it is not always the best translation. Depending on context, follower, underling, subordinate, or dependent may be more accurate.

8. 若頭 (Wakagashira)

若頭 is a senior rank commonly described as the position immediately below the group head.

English subtitles may use underboss, second-in-command, lieutenant, or senior executive. None is a perfect universal translation because real structures vary.

若頭が組員を集めた。
Wakagashira ga kumiin o atsumeta.
The wakagashira gathered the members.

9. 兄貴 and 兄貴分 (Aniki / Aniki-bun)

兄貴 literally means an older brother, said with respect, affection, or toughness.

Among craftspeople, young men, delinquents, and yakuza characters, it may address a respected senior male.

兄貴、どうしますか。
Aniki, dō shimasu ka?
What should we do, bro/boss?

10. 舎弟 (Shatei)

舎弟 can mean one’s younger brother, another person’s younger brother, or a junior brother-like subordinate.

In underworld fiction and organizational vocabulary, it often suggests a junior member placed in a younger-brother position.

彼は親分の舎弟だ。
Kare wa oyabun no shatei da.
He is a junior brother-like associate of the boss.

Do not assume that every occurrence is criminal. In formal or older Japanese, 舎弟 may simply mean “my younger brother.”

11. 兄弟分 (Kyōdaibun)

兄弟分 describes unrelated people who form or are treated as having a brother-like bond.

二人は兄弟分の杯を交わした。
Futari wa kyōdaibun no sakazuki o kawashita.
The two exchanged cups to establish a sworn-brother relationship.

The term is not exclusive to organized crime. Similar symbolic brother relationships have existed in folk custom, work communities, sports, and entertainment.

12. 盃 / 杯事 (Sakazuki / Sakazukigoto)

盃 / 杯 (sakazuki) means a sake cup. 杯事 / 盃事 (sakazukigoto) means a ritual exchange of sake cups used to confirm a bond or promise.

13. 代紋 (Daimon)

代紋 means an emblem or crest representing a yakuza family or organization.

The emblem represents collective identity and reputation. In fiction, harming the emblem or using it without permission may symbolize insulting the entire group.

14. 仁義 (Jingi)

仁義 has several meanings.

仁義を切る (Jingi o Kiru)

仁義を切る can mean to give a formal, formulaic greeting or pay one’s respects in a traditional underworld style.

旅人は土地の親分に仁義を切った。
Tabibito wa tochi no oyabun ni jingi o kitta.
The traveler formally paid his respects to the local boss.

In modern ordinary Japanese, the phrase can also be used jokingly or figuratively for properly introducing oneself and observing protocol.

15. 任侠 (Ninkyō)

任侠 describes an ideal of helping the weak, resisting the strong, valuing duty, and risking oneself for what is considered right.

The word expresses an ideal, not an objective description of organized crime.

16. 極道 (Gokudō)

極道 originally describes extreme bad conduct, dissipation, or a person whose behavior is morally uncontrolled.

In modern entertainment, it is often used dramatically for the yakuza world, a gangster, or “the way of the underworld.”

彼は極道の世界から足を洗った。
Kare wa gokudō no sekai kara ashi o aratta.
He left the criminal underworld.

The phrase 足を洗う literally means “wash one’s feet” and figuratively means to leave a disreputable occupation or way of life.

17. 堅気 (Katagi)

堅気 means respectable, honest, steady, law-abiding, or belonging to an ordinary legitimate occupation.

In underworld language, it contrasts ordinary civilians with people in criminal or disreputable occupations.

堅気の人には迷惑をかけるな。
Katagi no hito ni wa meiwaku o kakeru na.
Do not cause trouble for ordinary civilians.

18. 博徒 (Bakuto)

博徒 means a professional gambler or person who makes a living through gambling.

Historical police and encyclopedia accounts describe bakuto groups as one of the major lineages from which modern organized-crime structures developed.

Bakuto culture is associated in historical descriptions with gambling territories, parent–child hierarchy, ritual cups, and the 8-9-3 origin traditionally linked to the word yakuza.

19. 的屋 and 香具師 (Tekiya / Yashi)

的屋 and 香具師 refer historically to itinerant traders, street vendors, festival-stall merchants, and people connected with outdoor entertainment and sales.

Like bakuto groups, tekiya organizations developed family names, territories, parent–child relationships, and strict internal ranks. Police histories identify bakuto and tekiya customs as important roots of later yakuza organization.

20. ちんぴら (Chinpira)

ちんぴら is a strongly negative word for a small-time hoodlum, immature tough, delinquent, or low-ranking underworld figure.

あんなちんぴらを相手にするな。
Anna chinpira o aite ni suru na.
Do not get involved with a small-time thug like that.

The word is insulting. Do not use it casually to describe someone who merely looks rough.

21. シマ and 縄張り (Shima / Nawabari)

縄張り means territory, turf, sphere of influence, or jurisdiction. It is also an ordinary word used for animals, government departments, sales territories, and organizations.

シマ / 島 can mean a limited area or sphere of influence, especially in entertainment and underworld contexts.

そこは別の組のシマだ。
Soko wa betsu no kumi no shima da.
That is another group’s territory.

22. みかじめ料 (Mikajime-ryō)

みかじめ料 refers to money illegally demanded from businesses in a claimed territory in exchange for “permission,” noninterference, or supposed protection.

店はみかじめ料の支払いを拒否した。
Mise wa mikajime-ryō no shiharai o kyohi shita.
The business refused to pay protection money.

23. 指詰め and 指を詰める (Yubitsume / Yubi o Tsumeru)

指を詰める literally means to shorten or cut off a finger. In yakuza-related usage, it refers to cutting part of one’s finger as an apology or act of responsibility-taking.

This is a harmful act, not an ordinary or admirable method of apologizing. Fiction may use it as a dramatic symbol of responsibility and submission.

24. 破門 (Hamon)

破門 literally means expulsion from a school, tradition, organization, or master–disciple relationship.

In organized-crime reporting, it describes an internal expulsion. News terminology often explains that some uses of 破門 leave open the possibility of later return.

彼は組から破門された。
Kare wa kumi kara hamon sareta.
He was expelled from the group.

The word is not exclusive to organized crime. A traditional teacher can also expel a disciple from an artistic or martial lineage.

25. 絶縁 (Zetsuen)

絶縁 means cutting off relations or severing a connection.

In organized-crime news terminology, it is normally described as a more final and severe exclusion than 破門.

26. 事務所 (Jimusho)

事務所 simply means an office. In news or crime drama, 組事務所 or 暴力団事務所 means an office used by an organized-crime group.

The word itself is completely ordinary. Do not translate every 事務所 as “gang headquarters.”

27. 一家 (Ikka)

一家 normally means one household or one family.

In historical and underworld organization names, it can mean a family-like group centered on a leader.

The word reflects the fictive-kinship structure: a leader as parent, followers as children, and senior or equal members as brothers.

28. 跡目 (Atome)

跡目 means succession to a house, family line, name, property, office, or leadership position.

In a yakuza story, 跡目争い refers to a succession dispute over who will inherit leadership.

次の跡目を誰が継ぐのか。
Tsugi no atome o dare ga tsugu no ka?
Who will succeed to the leadership?

This is not exclusively a crime word. Historically, it can describe succession within houses, businesses, crafts, and hereditary positions.

29. 手打ち (Teuchi)

手打ち has several meanings, including handmade noodles and concluding an agreement.

In a conflict context, 手打ち means settlement, reconciliation, or bringing a dispute to an agreed end.

Common Mistakes When Learning Yakuza Words

Mistake 1: Treating Every Word as Secret Slang

Words such as 組, 事務所, 一家, 兄貴, 兄弟, and 絶縁 are ordinary Japanese words whose meaning changes with context.

Mistake 2: Treating Fictional Rank Charts as Universal

Organizations can use different titles and authority structures. A subtitle’s “captain,” “lieutenant,” or “underboss” is a translation choice.

Mistake 3: Confusing a Relationship Term with an Office

Mistake 4: Assuming Ninkyō Describes Reality Objectively

任侠 presents an ideal of chivalry. It does not erase the real violence, coercion, intimidation, and illegal profit associated with organized crime.

Mistake 5: Calling a Rough-Looking Person Yakuza or Chinpira

Appearance, tattoos, accent, clothing, or occupation do not prove criminal membership. Such labels can be insulting and defamatory.

Mistake 6: Using Aniki with Strangers

兄貴 can sound rough, overly familiar, theatrical, or subcultural. It is not a general polite form of address.

Mistake 7: Assuming Tattoos or Missing Fingers Prove Membership

Neither physical feature is reliable evidence of identity or affiliation.

Mistake 8: Romanticizing Harmful Customs

Practices such as finger-cutting and coercive internal discipline are harmful, not admirable cultural techniques.

Mistake 9: Confusing Historical Traders with Modern Criminal Membership

Bakuto and tekiya are important historical lineages, but a modern festival vendor or person who gambles is not automatically connected with organized crime.

Mistake 10: Learning Criminal Terms Without Learning Ordinary Meanings

Understanding the ordinary meanings of 組, 家, 兄弟, 親, 子, 縁, and 事務所 makes the underworld metaphors much easier to understand.
