心臓

§ What 心臓 means

The Japanese word for 'heart' as in the organ that pumps blood, is 心臓 (shinzou). This is a very direct and practical word. You'll hear it in medical contexts, when talking about health, or simply describing the physical heart.

Japanese Word

心臓 (しんぞう)

Meaning

Heart (organ)

CEFR Level

A2

§ When to use 心臓

You use 心臓 specifically when you are talking about the physical organ. It's not used for emotional 'heart' or the 'heart of a matter' – those have different Japanese words. Think of it strictly as the biological pump in your chest.

Hint

The doctor examined my heart.

Here's another example showing its direct use:

Hint

My heart was pounding (thumping).

You'll often encounter 心臓 when talking about:

• Medical conditions (e.g., 心臓病 - heart disease)
• Anatomy classes
• Talking about your pulse or heartbeat
• Any situation where the physical organ is the topic

For example, if you want to say 'He has a kind heart,' you would not use 心臓. You would likely use 心 (kokoro), which refers more to the spirit, mind, or emotional heart. It's a common mistake for English speakers to translate 'heart' directly, so be mindful of this distinction.

Hint

His heart is strong (physically).

This sentence directly refers to the physical strength of the heart as an organ, perhaps in a health context. If you said, 'His 心 is strong,' it would imply mental or emotional fortitude. This subtle difference is important for natural communication.

So, in summary, when you're talking about the pump in your chest, the organ that keeps you alive, reach for 心臓. It's straightforward and correct.

So, you've learned that 心臓 (shinzou) means 'heart' as in the organ. That's a great start! But how do people actually use this word in daily life? Let's dive into some common scenarios where you might hear or use 心臓.

§ In Medical and Health Contexts

Naturally, when talking about health, 心臓 comes up a lot. You'll hear it in hospitals, at the doctor's office, or even when discussing general health issues with friends or family.

Definition

Heart (organ)

Kare wa shinzou no byouki de nyuuinchimashita. (He was hospitalized due to a heart illness.)

Shinzou no kenkou ni wa undou ga taisetsu desu. (Exercise is important for heart health.)

§ In Everyday Conversation (Figurative Use)

Just like in English, 'heart' can be used figuratively in Japanese, though 心臓 is *less* common for emotions. For emotions, you'd usually use 心 (kokoro). However, 心臓 can describe a physical reaction to strong emotions.

Bikkuri shite shinzou ga tobidesou ni natta. (I was so surprised my heart almost jumped out.)

Kare no kotoba de shinzou ga dokidoki shita. (My heart pounded from his words.)

§ In News and Media

You'll often encounter 心臓 in news reports, especially those covering health topics, medical advancements, or public health campaigns.

• Medical Breakthroughs: News about new treatments for 心臓病 (shinzou-byou - heart disease) or 心臓移植 (shinzou-ishoku - heart transplant).

• Public Health Warnings: Campaigns advising people on how to protect their 心臓 from lifestyle diseases.

• Human Interest Stories: Sometimes, stories about people overcoming 心臓-related challenges.

Saishin no kenkyuu de, shinzou-byou no risuku o herasu houhou ga hakken saremashita. (In the latest research, a method to reduce the risk of heart disease was discovered.)

§ In Specific Phrases

There are a few fixed phrases where 心臓 is used. Knowing these will make your Japanese sound more natural.

• 心臓が強い (shinzou ga tsuyoi): Literally 'strong heart,' meaning someone is bold, fearless, or has strong nerves. It's about mental fortitude.

  彼は心臓が強いから、どんな困難にも立ち向かえる。

  Kare wa shinzou ga tsuyoi kara, donna konnan ni mo tachimukaeru. (He's got a strong heart, so he can face any difficulty.)

• 心臓が弱い (shinzou ga yowai): Literally 'weak heart,' meaning someone is timid, easily scared, or has weak nerves. Not necessarily about physical health.

  私は心臓が弱いので、ホラー映画は見られません。

  Watashi wa shinzou ga yowai node, horā eiga wa miraremasen. (I have a weak heart, so I can't watch horror movies.)

By understanding these contexts, you can confidently use 心臓 in your conversations and comprehend it when you hear it. Keep practicing, and your Japanese will get stronger!

§ Don't confuse 心臓 (shinzou) with other words for heart

When you're learning Japanese, it's really common to encounter several words that can be translated as 'heart' in English. This can lead to some confusion, especially with words like 心臓 (shinzou), 心 (kokoro), and ハート (haato). Let's clear this up.

The main difference

心臓 (shinzou) specifically refers to the physical organ that pumps blood. It's medical or biological. Think of it as the 'cardiac heart'.

On the other hand, 心 (kokoro) is much broader. It refers to your mind, spirit, emotions, and even your 'heart' in a metaphorical sense (like having a kind heart). It's rarely used for the physical organ.

When to use which

Use 心臓 (shinzou) when you're talking about the actual organ. For example, if someone has a heart condition, or if you're discussing anatomy.

Use 心 (kokoro) for feelings, intentions, and the non-physical 'heart'.

And then there's ハート (haato). This is a loanword from English 'heart'. It's usually used for the heart shape (♥) or in more casual, romantic contexts, especially amongst younger people. It's very informal and you wouldn't use it for medical or deep emotional situations.

Key takeaway

Always go with 心臓 (shinzou) when you mean the literal, pumping organ.

§ Don't use 心臓 for figurative expressions

In English, we use 'heart' in many idioms and figurative expressions. For example, 'to have a change of heart' or 'to wear your heart on your sleeve'. You cannot directly translate these using 心臓 (shinzou).

Why it doesn't work

Because 心臓 (shinzou) is strictly the physical organ, using it in a figurative sense would sound extremely odd, or even comical, to a native Japanese speaker.

For these kinds of expressions, you'll almost always use 心 (kokoro) or completely different Japanese phrases. For instance:

• 'To have a change of heart' in Japanese is often expressed with 気 (ki), like 気が変わる (ki ga kawaru).
• 'To wear your heart on your sleeve' might be similar to 感情が顔に出やすい (kanjou ga kao ni deyasui - emotions show easily on one's face) or 隠し事をしない (kakushigoto o shinai - doesn't hide things).
