寄生虫
When we talk about living things, some of them need to live off others to survive. In Japanese, we call such a creature 寄生虫 (kiseichū).
Think of it like a tiny guest that never leaves and needs its host for food and shelter. It's often used in a biological context, like a tick on a dog.
While it technically means a parasite, it can also sometimes be used to describe a person who relies heavily on others without contributing much themselves, though that's a less common and more informal usage.
When discussing biological parasites, 寄生虫 (kiseichū) is the standard and most direct term. It refers to an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense. While it primarily refers to living organisms, in a figurative sense, you might hear it used to describe someone who is dependent on others, similar to the English 'parasite' for a person. However, its most common and primary usage remains in a biological context. Understanding this term is crucial for topics related to biology, health, and even some discussions of social dynamics.
Alright, let's talk about how to use the word 寄生虫 (kiseichū) in Japanese. It means 'parasite,' and while it sounds a bit technical, it's used pretty straightforwardly in sentences. You'll mainly see it as a noun, and it works just like other nouns when you're forming sentences.
§ Basic Usage with Particles
Like most Japanese nouns, 寄生虫 (kiseichū) pairs up with particles to show its role in a sentence. Here are some common ways you'll use it.
As the subject of a sentence (with が ga): When 寄生虫 is the one doing the action, you'll use が (ga) after it.
この魚には寄生虫がいます。
This fish has parasites.
As the object of a sentence (with を o): If something is acting upon 寄生虫, you'll use を (o).
寄生虫を駆除する薬が必要です。
We need medicine to exterminate parasites.
Showing possession or modification (with の no): You can use の (no) to link 寄生虫 to another noun, indicating possession or description.
寄生虫の問題は深刻です。
The parasite problem is serious.
§ Common Phrases and Contexts
While 'parasite' often has a biological meaning, 寄生虫 can also be used metaphorically, just like in English, to describe someone who lives off others. However, be careful with this; it's quite strong and negative.
§ Examples in Different Scenarios
Let's look at a few more examples to solidify your understanding.
彼らは体の内部に寄生虫がいると診断された。
They were diagnosed with parasites inside their bodies.
不衛生な環境では寄生虫が繁殖しやすい。
Parasites tend to breed easily in unsanitary environments.
この野菜は寄生虫から守られている。
These vegetables are protected from parasites.
§ Formal vs. Informal
寄生虫 (kiseichū) itself is a neutral noun. Its formality depends more on the surrounding sentence structure and the context of the conversation. In a medical or scientific context, it's perfectly normal and formal. In casual conversation, it would be used if the topic of parasites came up naturally.

§ Don't Confuse with General 'Pest' Terms
Many learners mistakenly use 寄生虫 (kiseichū) for any kind of pest or nuisance. While a parasite is definitely a pest, 寄生虫 specifically refers to a biological organism living on or in another organism. It's not a general word for something annoying or bothersome. If you want to talk about pests like insects in your house, or even just a general nuisance, other words are more appropriate.
§ Using it Figuratively Too Broadly
While 寄生虫 can sometimes be used metaphorically to describe someone who lives off others without contributing (a 'freeloader'), this usage is quite strong and often carries a negative connotation. Be careful not to overuse it or apply it to situations where a milder term would be better. For example, simply calling someone a 'stay-at-home child' isn't usually a reason to label them a 寄生虫.
彼はいつも人のお金で生活している寄生虫だ。
He's always living off other people's money, he's a parasite.
This example shows the figurative use. However, consider if a milder term like 居候 (isōrō - sponger, freeloader) might be more appropriate depending on the situation and your intention.
- DEFINITION
- 居候 (isōrō): A person who lives in another's house without paying rent, a sponger or freeloader.
§ Pronunciation Pitfalls
The pronunciation of 寄生虫 (kiseichū) can be tricky for some. Pay attention to the long 'ei' sound and the 'chū' at the end. Mispronouncing it might lead to confusion or simply make it harder for native speakers to understand you.
き (ki)
せい (sei) - often mispronounced as a short 'e'
ちゅう (chū) - a common difficulty is getting the 'ch' sound right
§ Overlooking Context
Like many words, the meaning and nuance of 寄生虫 depend heavily on context. In a biology textbook, it's a neutral scientific term. In a casual conversation, if someone calls another person a 寄生虫, it's an insult. Always consider who you're talking to and the situation.
この湖には様々な種類の寄生虫が生息している。
Various kinds of parasites inhabit this lake.
Here, it's a scientific context, so the term is neutral. Be aware of the difference.

Cómo usarlo
寄生虫 (kiseichū) is the Japanese word for 'parasite'. It can refer to both biological parasites (like intestinal worms or ticks) and, metaphorically, to a person who lives off others without contributing, often in a derogatory sense. When used metaphorically, it implies that the person is a burden.
The term is quite direct and is commonly used in both scientific/medical contexts and in casual conversation when describing someone who is seen as freeloading.
A common mistake might be to use 寄生虫 too broadly for any dependent relationship. While it can be metaphorical, it often carries a negative connotation of exploitation or being a burden. For simply depending on someone in a non-negative way, other phrases like '世話になる' (to be taken care of/to be indebted to) or '人に頼る' (to rely on someone) might be more appropriate depending on the context. For example, a child is dependent on their parents, but they are not typically called a 寄生虫 unless their dependency is seen as excessive or burdensome in a negative way.

Preguntas frecuentes
10 preguntasThe kanji for 寄生虫 literally mean 'guest' (寄), 'life' (生), and 'insect' (虫). So, it's like a 'guest life insect,' which pretty directly translates to parasite.
Yes, you can! While its primary meaning is a biological parasite, 寄生虫 can also be used metaphorically to describe someone who lives off others without contributing, like a 'social parasite.' For example:
- 彼は家族の寄生虫だ。(Kare wa kazoku no kiseichū da.) - He is a parasite to his family.
Yes, just like in English, there are many types of 寄生虫, referring to different organisms. You might hear specific terms like:
- 腸内寄生虫 (chōnai kiseichū) - intestinal parasite
- 外部寄生虫 (gaibu kiseichū) - external parasite
You'll most often encounter 寄生虫 in scientific or medical contexts, or when discussing health and biology. In casual conversation, the metaphorical use is less common but definitely understood.
It's a neutral, descriptive term when referring to biological parasites. However, when used metaphorically to describe a person, it's quite derogatory and offensive. Use with caution in that context.
You might hear or read phrases like:
- 寄生虫に感染する (kiseichū ni kansen suru) - to be infected with a parasite
- 寄生虫を駆除する (kiseichū o kujo suru) - to eliminate parasites
Biologically, 寄生虫 implies a negative relationship where one organism benefits at the expense of another. Metaphorically, it's always used negatively to describe someone exploitative.
寄生虫 specifically refers to organisms that live off another host. Other words like 虫 (mushi - insect/bug) or 害虫 (gaichū - harmful insect/pest) are broader and don't necessarily imply a parasitic relationship.
Not directly. You would typically use it with する (suru) to describe the act of parasitism, or with の (no) to modify a noun, like 寄生虫の病気 (kiseichū no byōki - parasitic disease).
For biological contexts, 寄生虫 is the standard term. If you're talking about someone living off others, you might use more general phrases like 人の金で暮らす人 (hito no kane de kurasu hito - a person living off others' money) or simply call them 怠け者 (namakemono - lazy person), though these aren't exact synonyms for parasite.
