설명 記憶力 in your Level:

At the A1 level, you are just starting to learn about basic human attributes. While 'kiokuryoku' is a complex word, you can think of it as 'the power to remember.' At this stage, you don't need to use it in long sentences. Just focus on the idea that 'kioku' means memory and 'ryoku' means power. You might hear someone say 'kiokuryoku ga ii' (memory is good) or 'kiokuryoku ga warui' (memory is bad). It is like saying 'I have a good brain for remembering.' You can use it to talk about yourself when you forget a new Japanese word. For example, 'Watashi wa kiokuryoku ga warui desu' (I have a bad memory). This is a simple way to excuse yourself if you forget something. Remember that in Japanese, we don't say 'I have a memory,' we say 'Memory capacity exists' using the particle 'ga'. This is a very important grammar point for beginners. Even though this word has three kanji, the 'ryoku' part is very common in other words like 'benkyō-ryoku' (study power) or 'tairyoku' (physical strength). Learning 'kiokuryoku' helps you see how Japanese builds big words from smaller, simple ideas. Just try to remember the sound 'ki-o-ku-ryo-ku' and associate it with the 'power' of your mind. It is a useful word to know when you are in a classroom setting where everyone is trying to remember many new things every day. Don't worry about the difficult kanji yet; just focus on the meaning and the simple 'ga ii / ga warui' pattern.

At the A2 level, you can begin to use 'kiokuryoku' in slightly more descriptive ways. You are learning how to connect ideas and express opinions. You might talk about why your memory is good or bad. For example, 'Kinō nemurenakatta kara, kyō wa kiokuryoku ga yowai desu' (Because I couldn't sleep yesterday, my memory capacity is weak today). At this level, you can also start using the word with verbs like 'kitaeru' (to train) in simple sentences. You might say, 'Kiokuryoku o kitaeru tame ni, kanji o renshū shimasu' (To train my memory capacity, I practice kanji). This shows you are moving beyond just describing a state to describing an action. You will also notice this word in simple health tips or brain games. The word is very common in Japan because people value the ability to remember things well. You can use it to compliment others too: 'Tanaka-san wa kiokuryoku ga takai desu ne!' (Mr. Tanaka, your memory capacity is high, isn't it!). Using 'takai' (high) instead of just 'ii' (good) makes you sound a bit more advanced. You should also be aware that 'kioku' is the thing you remember, and 'kiokuryoku' is the skill. If you forget a name, you might say 'kiokuryoku ga...' and trail off, and people will understand you are having trouble remembering. This word is a great way to talk about your learning process as you study more complex Japanese grammar and vocabulary.

As a B1 learner, you should be comfortable using 'kiokuryoku' in various contexts, including professional and academic discussions. This is the level where you start to understand the nuance between 'kiokuryoku' and 'ankiryoku' (rote memorization). You can explain your study methods using this word. For example, 'Kiokuryoku o takameru ni wa, kurikaeshi fukushū suru koto ga taisetsu desu' (To heighten memory capacity, it is important to review repeatedly). You will encounter this word in news articles about health, aging, and technology. It is often used with the noun 'teika' (decline). You might read a sentence like 'Karei ni yoru kiokuryoku no teika' (The decline of memory capacity due to aging). This is a very common phrase in Japan's aging society. You should also be able to use it with more complex particles and connectors. For instance, 'Kiokuryoku ni jishin ga arimasen' (I have no confidence in my memory capacity). At this level, you are expected to understand that memory is treated as a measurable faculty. You might discuss how stress or diet affects your 'kiokuryoku'. You are also moving into the territory where you can understand 'kiokuryoku' in literature or dramas, where a character's incredible memory might be a key plot point. Focus on expanding your collocations: 'kiokuryoku o iji suru' (maintain), 'kiokuryoku o katsuyō suru' (utilize), and 'kiokuryoku ga otoroeru' (worsen/decline). This will make your Japanese sound more natural and sophisticated.

At the B2 level, you are expected to use 'kiokuryoku' with precision and understand its place in more formal or scientific discourse. You can discuss the mechanics of memory, such as the difference between short-term and long-term memory capacity. For example, 'Tanki-kiokuryoku wa kagirarete iru ga, chōki-kiokuryoku wa bōdai na jōhō o hoji dekiru' (Short-term memory capacity is limited, but long-term memory capacity can retain vast amounts of information). You will see this word in psychological journals, educational white papers, and business strategy documents. It's often used to describe the human element in an increasingly digital world—how we must still rely on our 'kiokuryoku' despite having smartphones. You can also use it in abstract or metaphorical ways. For instance, in a debate about history education, you might argue that 'kiokuryoku' is less important than 'shikōryoku' (thinking power) or 'hihanteki shikō' (critical thinking). You should be familiar with related terms like 'shashinteki kiokuryoku' (photographic memory) and how they are used in media. Your grammar should be flawless when using this word, correctly identifying when it is a subject, object, or part of a compound noun. You might also explore the etymology of the kanji '憶' and how the 'heart' radical implies a deeper, more emotional connection to memory than just data storage. This level of understanding allows you to engage in deep conversations about the nature of the mind and the future of human intelligence in the age of AI.

At the C1 level, you have a near-native grasp of 'kiokuryoku' and can use it in highly specialized contexts. You can discuss the neurobiological aspects of memory capacity, using terms like 'shinkei-kaizōsei' (neuroplasticity) in conjunction with 'kiokuryoku'. You might analyze how 'kiokuryoku' is portrayed in Japanese literature, perhaps comparing the clinical use of the term in modern novels to the more evocative 'omoidasu' (to recall) in classical works. You are capable of writing essays on the impact of digital amnesia on the 'kiokuryoku' of the younger generation. Your vocabulary should include very formal synonyms like 'hojiryoku' (retention power) or 'meiki' (engraving in mind). You can participate in academic seminars or professional conferences where the 'decline of kiokuryoku' is discussed as a socio-economic challenge for Japan. You understand the subtle social cues when someone uses this word—for example, if a politician uses it to dodge a question ('I have no kioku/kiokuryoku regarding that matter'), you recognize the legal and social implications. You can also use the word in creative writing to describe a character's mental state with great detail. Your ability to switch between the technical 'kiokuryoku' and the colloquial 'oboe' depending on the audience is a hallmark of this level. You are not just using the word; you are manipulating it to convey specific tones, from the coldness of a medical report to the warmth of a personal memoir.

At the C2 level, you possess a masterly command of 'kiokuryoku' and its entire linguistic ecosystem. You can synthesize information from various fields—neuroscience, philosophy, and history—to discuss the concept of memory capacity in Japan. You might provide a critique of the Japanese 'shiken-jigoku' (examination hell) and its over-reliance on 'ankiryoku' versus the broader 'kiokuryoku'. You can interpret the most complex legal or medical documents where 'kiokuryoku' is a pivotal factor in determining mental competence or witness credibility. Your use of the word is indistinguishable from a highly educated native speaker. You might even use it in philosophical inquiries into the nature of the self: 'If our kiokuryoku were to vanish, what would remain of our identity?' You are comfortable with the most obscure kanji compounds involving 'kioku', and you can explain the historical evolution of the term from the Meiji era to the present. You can lead discussions on the ethics of 'kiokuryoku-zōkyaku' (memory enhancement) through technology or drugs. At this stage, the word is a tool that you use with total fluidity and nuance, capable of expressing the most minute differences in meaning and tone. You understand not just what the word means, but the entire cultural and historical weight it carries within the Japanese psyche, from the importance of 'remembering one's roots' to the modern obsession with 'brain health'.

연습하기 예시 노트와 팁

記憶力 30초 만에

Kiokuryoku means 'memory capacity' or 'the power to remember.' It is a noun used to describe an individual's mental ability to store and recall data.
It is commonly paired with adjectives like 'good' (ii) or 'bad' (warui) and verbs like 'train' (kitaeru) or 'improve' (takameru) in various contexts.
The word is essential in discussions about education, aging, and health in Japan, often appearing in news, TV quiz shows, and medical reports.
It differs from 'kioku' (the memory itself) by focusing on the 'power' or 'faculty' behind the act of remembering, making it a more technical term.

The Japanese word 記憶力 (きおくりょく - kiokuryoku) is a compound noun that translates most accurately to "memory capacity" or "the power of memory." To understand this word deeply, one must look at its constituent parts: ki (記 - to record), oku (憶 - to remember/think), and ryoku (力 - power or strength). Unlike the simple word kioku (memory), which refers to the memory itself or the act of remembering, kiokuryoku specifically targets the ability or capacity of an individual to retain and recall information. It is a measurable trait, often discussed in educational, medical, and self-improvement contexts.

Cognitive Ability: In Japanese society, high memory capacity is often equated with academic success, as the entrance examination system historically relied heavily on rote memorization of kanji, history, and formulas.
Daily Life Nuance: When someone says their 'kiokuryoku' is declining, they are usually referring to the biological aging process or the feeling of being overwhelmed by modern information overload.

彼は一度見たものを忘れない、驚異的な記憶力の持ち主だ。(He is the possessor of an incredible memory capacity; he never forgets anything he sees once.)

The term is frequently used when comparing individuals or discussing the effects of lifestyle choices on the brain. For instance, you will hear it in commercials for supplements (DHA/EPA), in brain-training game descriptions (like those popular on Nintendo consoles), and in pedagogical discussions about how to help students study more effectively. It carries a slightly more technical or objective tone than the colloquial 'oboe' (learning/memory), making it suitable for both professional reports and serious personal conversations.

In the context of the CEFR B1 level, learners should recognize that kiokuryoku is often paired with adjectives like yoi (good), warui (bad), sugureta (excellent), or otoroeta (declined). It is not just about having a memory, but about the quality and strength of that memory system within the brain. Understanding this word allows you to participate in conversations about aging, education, and self-improvement, which are common topics in Japanese media and social interactions.

最近、記憶力が落ちてきたような気がする。(I feel like my memory capacity has been dropping lately.)

Professional Context: In medical settings, doctors might assess a patient's memory capacity using specific tests (like the Hasegawa scale) to check for early signs of cognitive impairment.

Historically, the concept of memory in Japan was tied to the 'heart' (kokoro), as seen in the radical of the second kanji 憶. This suggests that memory was not just a cold, mechanical storage of data, but something that involved the essence of the person. However, in modern usage, kiokuryoku has taken on a more scientific and functional meaning, aligning with global psychological terms. It covers both short-term memory (tanki-kioku) and long-term memory (chōki-kioku) abilities.

このサプリメントは、中高年の記憶力を維持する助けになります。(This supplement helps maintain the memory capacity of middle-aged and elderly people.)

To summarize, kiokuryoku is the functional power of the mind to store and retrieve. It is an essential noun for anyone discussing human potential, health, or learning strategies in Japanese. By mastering this word, you move beyond simple verbs like 'oboyeru' (to remember) and begin to describe the underlying mental faculty that makes remembering possible.

試験に合格するためには、単なる記憶力だけでなく、理解力も必要だ。(To pass the exam, you need not just memory capacity, but also the power of understanding.)

Educational Philosophy: Modern Japanese education is shifting toward 'thinking power' (shikōryoku), but 'kiokuryoku' remains the bedrock of foundational knowledge acquisition.

Using 記憶力 (kiokuryoku) correctly involves understanding its role as a noun and the specific verbs and adjectives it typically pairs with. Since it describes a personal attribute or a biological function, it often appears as the subject of a sentence using the particle ga, or as the object of an action using the particle o. Let's break down the most common grammatical patterns.

Subject with Adjectives: [Person] wa kiokuryoku ga [Adjective] desu.
Example: 祖父は80歳ですが、記憶力が非常に良いです。(My grandfather is 80, but his memory capacity is very good.)
Action with Verbs: Kiokuryoku o [Verb].
Example: 毎日読書をして、記憶力を鍛えています。(I read every day to train my memory capacity.)

睡眠不足は記憶力の低下を招く。(Lack of sleep leads to a decline in memory capacity.)

One interesting aspect of kiokuryoku is how it interacts with the word teika (decline) or genshō (decrease). In formal or medical contexts, you will see phrases like kiokuryoku no teika (decline in memory capacity). This is a very common way to describe the symptoms of aging or stress. Conversely, to improve memory, verbs like takameru (to heighten/improve) or kitaeru (to forge/train) are used. These verbs imply that memory is like a muscle that can be developed through effort.

When describing someone who can memorize things quickly, the adjective sugureta (excellent) or the phrase takai kiokuryoku (high memory capacity) is often used. In casual settings, people might say kiokuryoku ga yabai (my memory is crazy/bad), depending on the context. It is also common to see it used in the negative: kiokuryoku ni jishin ga nai (I have no confidence in my memory capacity).

彼女の並外れた記憶力には、いつも驚かされる。(I am always surprised by her extraordinary memory capacity.)

Compound Usage: Kiokuryoku + Test/Game/Training.
Example: 記憶力テストを受ける (to take a memory capacity test).

In more advanced Japanese, you might encounter kiokuryoku being used to describe non-human entities, such as computer systems or AI models, although 'memory' in computing is usually memori. Using kiokuryoku for a machine gives it a personified, almost biological nuance. However, 99% of the time, it refers to the human brain.

ストレスが溜まると、記憶力が鈍くなることがある。(When stress builds up, your memory capacity can become dull.)

Finally, let's look at the usage with iji suru (to maintain). As Japan's population ages, the phrase kiokuryoku o iji suru has become a staple of marketing for healthy foods and exercises. It implies a proactive stance against the natural decline of cognitive functions. Understanding these collocations helps you sound more natural and precise in your speech.

どうすれば記憶力をアップさせることができますか？(How can I increase my memory capacity?)

Formal Writing: Kiokuryoku wa kojinsa ga ookii. (Memory capacity has large individual differences.)

You will encounter 記憶力 (kiokuryoku) in a wide variety of real-world scenarios in Japan. One of the most common places is on television, specifically during 'variety shows' or quiz programs. Japan has a long-running fascination with 'brain power' (nōryoku), and many shows feature celebrities or 'genius' students competing in memory challenges. In these shows, announcers often shout about the odorokubeki kiokuryoku (surprising memory capacity) of the contestants.

TV Quiz Shows: Hosts often highlight a guest's ability to memorize hundreds of digits or the names of every station on a train line as a 'monster-level kiokuryoku'.
The Pharmacy: Look at the labels of 'Kinōsei Hyōji Shokuhin' (Foods with Function Claims). Many supplements for the elderly claim to 'support the maintenance of kiokuryoku'.

テレビ番組で、彼の天才的な記憶力が披露された。(His genius-level memory capacity was showcased on a TV program.)

In the workplace, kiokuryoku is discussed during performance reviews or when assigning tasks. A manager might say, "I'm relying on your kiokuryoku for this project," implying that the employee is expected to keep track of many complex details without constant documentation. Conversely, colleagues might joke about their kiokuryoku no genkai (the limit of their memory capacity) when they are overwhelmed with work.

Another frequent setting is the doctor's office or health clinics. As Japan is a super-aging society, cognitive health is a national priority. News segments and health magazines (like 'Tarzan' or 'Croissant') frequently feature articles titled "How to Prevent the Decline of Kiokuryoku." These articles often suggest eating blue-backed fish (rich in DHA) or doing 'fingertip exercises' to stimulate the brain.

健康診断で、記憶力に関するアンケートに答えた。(At the health checkup, I answered a questionnaire regarding my memory capacity.)

News Media: Scientific breakthroughs in Alzheimer's research are often reported with headlines about 'restoring kiokuryoku'.

In detective novels and anime (like 'Detective Conan'), characters often have 'photographic memories' described as shashinteki-kiokuryoku. This is a common trope where a character's high kiokuryoku allows them to solve a crime by remembering a minute detail from a crime scene. You'll hear this term in the dialogue of police procedurals and mystery dramas constantly.

彼は写真のような記憶力を持っていて、一度見た犯人の顔を忘れない。(He has a photographic memory capacity and never forgets the face of a criminal he has seen once.)

Finally, you will hear it in the context of sports and arts. A professional shogi player or a pianist is often praised for their kiokuryoku. In shogi, players must remember thousands of historical board positions. In music, pianists must memorize hours of complex scores. In both cases, kiokuryoku is seen as the foundational skill that allows for higher-level artistic expression.

将棋のプロ棋士は、並外れた記憶力を駆使して対局する。(Professional shogi players utilize their extraordinary memory capacity during their matches.)

Artistic Mastery: Actors are often asked in interviews how they manage their 'kiokuryoku' to learn long scripts for stage plays.

One of the most frequent mistakes English speakers make when using 記憶力 (kiokuryoku) is confusing it with the simpler word kioku (memory). While they are related, they are not interchangeable. Kioku refers to the mental record itself—the "data" in your brain. Kiokuryoku refers to the "hardware capability" or the processing power of the brain to handle that data. For example, you have a kioku of your childhood (a specific memory), but you have the kiokuryoku to remember your childhood (the ability).

Confusion with 'Kioku': Mistake: 'Kiokuryoku ga arimasu' (I have a memory of...).
Correct: 'Kioku ga arimasu' (I have a memory of...).
Explanation: Use 'kioku' for specific events and 'kiokuryoku' for the general skill.
Incorrect Verbs: Mistake: 'Kiokuryoku o oboyeru'.
Correct: 'Kiokuryoku o kitaeru'.
Explanation: You don't 'remember' your memory capacity; you 'train' or 'improve' it.

❌ 私は子供の頃の記憶力があります。(Incorrect: I have a memory capacity of my childhood.)

Another common error is using kiokuryoku when you actually mean ankiryoku (rote memorization power). While kiokuryoku is broad, ankiryoku is the specific ability to memorize things like vocabulary lists, numbers, or facts through repetition. If you are talking specifically about studying for a test, ankiryoku might be the more precise word, though kiokuryoku is never technically wrong in that context.

Learners also struggle with the particles. Because kiokuryoku is a quality, it is usually described with the particle ga followed by an adjective. Using o with an adjective (like 'kiokuryoku o ii') is a major grammatical error. You must use ga with stative descriptions and o with transitive actions (like 'kiokuryoku o takameru').

❌ 彼は記憶力をいいです。(Incorrect: He is memory capacity good.)

Overusing the Word: In casual conversation, Japanese people often say 'wasurechatta' (I forgot) or 'oboetenai' (I don't remember) rather than using the formal 'kiokuryoku'. Using 'kiokuryoku' in every sentence can make you sound like a textbook or a doctor.

Finally, watch out for the difference between kiokuryoku and shūchūryoku (concentration power). Often, when people think they have a bad memory, they actually have poor concentration. In Japanese, these are distinct 'powers' (-ryoku). If you can't remember where you put your keys because you weren't paying attention, that's a lack of shūchūryoku, not necessarily a failure of kiokuryoku.

❌ 記憶力がなくて、鍵の場所を忘れました。(Incorrect: I have no memory capacity, so I forgot the key's location.)

In summary, treat kiokuryoku as a technical term for the 'power of the brain' and use it with appropriate adjectives (ii/warui) and particles (ga/o). Avoid using it for specific memories or as a simple synonym for 'remembering'.

✅ 記憶力を高めるトレーニングをしています。(Correct: I am doing training to improve my memory capacity.)

Misspelling Kanji: Be careful with '憶' (Oku). It has the 'heart' radical on the left. Don't confuse it with '意' (I - meaning/mind), which lacks the vertical heart stroke.

To enrich your Japanese vocabulary, it's important to know the synonyms and related terms for 記憶力 (kiokuryoku). While kiokuryoku is the standard term, other words offer different nuances depending on whether you are talking about rote learning, deep recollection, or the act of not forgetting.

暗記力 (Ankiryoku): This refers specifically to 'rote memorization power.' It is used for things like memorizing vocabulary, digits of pi, or historical dates. It is more mechanical than 'kiokuryoku'.
覚え (Oboe): A more colloquial and versatile term. 'Oboe ga ii' means someone learns things quickly. It's less technical than 'kiokuryoku' and very common in daily life.
保持力 (Hojiryoku): Literally 'retention power.' This is used in psychology or technical contexts to describe how long information stays in the mind after being learned.

彼は暗記力がすごくて、英単語を一日で100個覚えた。(His rote memorization power is amazing; he memorized 100 English words in one day.)

When comparing kiokuryoku to oboe, think of the former as the 'hard drive capacity' and the latter as the 'ease of saving a file.' If someone is 'oboe ga hayai', they grasp things quickly. If someone has 'kiokuryoku ga ii', they can keep those things in their head for a long time. In professional settings, kiokuryoku is preferred for its objective tone.

Another related term is meiki (銘記), which means to 'engrave in one's mind' or 'remember clearly.' This is a very formal, literary term used when someone wants to emphasize that they will never forget a kindness or a lesson. It is much more emotional than the clinical kiokuryoku.

ご恩は一生、心に銘記いたします。(I will engrave your kindness in my heart for a lifetime.)

回想 (Kaisō): This means 'reminiscence' or 'reflection.' It refers to the act of looking back on the past, whereas 'kiokuryoku' is the ability to do so.

For those interested in the 'loss' side of things, bōkyaku (忘却) is the formal word for 'forgetting.' While wasureru is the common verb, bōkyaku is used in phrases like 'bōkyaku no kanata' (beyond the veil of forgetfulness). It provides a poetic contrast to the functional nature of kiokuryoku.

人間の記憶力には限界があり、忘却は避けられない。(Human memory capacity has limits, and forgetting is unavoidable.)

By understanding these alternatives, you can tailor your Japanese to the specific situation. Whether you are writing a medical report, studying for the JLPT, or reminiscing with a friend, you now have a range of words to describe the fascinating power of the human mind.

彼は単なる暗記力だけでなく、物事の本質を見抜く洞察力も持っている。(He has not just rote memorization power, but also the insight to see the essence of things.)

Conclusion: Mastering 'kiokuryoku' and its synonyms allows for a more nuanced discussion of human intelligence and cognitive health.

How Formal Is It?

Ishiki is consciousness or awareness. Sometimes confused because both relate to the mind, but they are completely different functions.

Kirokuryoku is the ability to keep records/logs (like a clerk), while Kiokuryoku is the mental ability to remember.

彼は記録力が高い。(He is good at keeping logs/records.)

사용법

frequency

High in educational, medical, and self-help contexts. Moderate in casual daily life.

자주 하는 실수

Using 'kiokuryoku' for a specific memory. → Use 'kioku'.
You don't say 'I have a memory capacity of meeting you.' You say 'I have a memory of meeting you.'
Saying 'Watashi wa kiokuryoku desu'. → Watashi wa kiokuryoku ga ii desu.
You are not the memory capacity itself; you possess it. Use the 'ga' pattern.
Confusing 'kiokuryoku' with 'kirokuryoku'. → Kiokuryoku (Memory) vs Kirokuryoku (Recording).
One is mental, the other is about keeping physical or digital logs.
Using 'tsuyoi' instead of 'ii' or 'takai'. → Kiokuryoku ga ii.
While 'tsuyoi' is occasionally used, 'ii' and 'takai' are the standard collocations.
Miswriting the kanji '憶'. → Check the heart radical.
Learners often forget the heart radical or mix up the right-side components.

팁

Use 'ga' not 'o'

When describing your memory, always use the particle 'ga'. 'Kiokuryoku ga ii' is correct. 'Kiokuryoku o ii' is a common mistake for English speakers.

Learn the '-ryoku' family

Learning 'kiokuryoku' helps you learn other words like 'shūchūryoku' (focus) and 'sōzōryoku' (imagination). They all follow the same patterns.

Complimenting seniors

Telling an older person 'Kiokuryoku ga ii desu ne' is a very polite and appreciated compliment in Japan.

Mnemonics

Use mnemonics to remember the kanji '憶'. The heart radical on the left tells you it's a mental/emotional state.

Softening the tone

If you want to sound less clinical, use 'oboe' instead of 'kiokuryoku' in casual settings.

Kanji Stroke Order

Pay attention to the stroke order of '憶'. It has 16 strokes and is often written incorrectly by learners.

Contextual Clues

In medical contexts, 'kiokuryoku' is often paired with 'teika' (decline) or 'iji' (maintenance).

Pitch Accent

Listen for the flat pitch of 'kiokuryoku'. It doesn't have a strong 'jump' in pitch like some other words.

Don't pluralize

Remember that Japanese nouns don't have plurals. One person's memory or a whole group's memory is still just 'kiokuryoku'.

Self-Deprecation

Using 'kiokuryoku ga warui' is a common way to be humble when someone praises your knowledge.

암기하기

기억법

Think of 'K-O-K-R' (Key Of Knowledge Retention). 'Ki-Oku' is the Key, and 'Ryoku' is the Power. You need the Key and the Power to have a high Kiokuryoku.

시각적 연상

Imagine a brain lifting heavy weights. Each weight is a book or a fact. The stronger the brain (ryoku), the more facts (kioku) it can lift and hold.

Word Web

Brain Study Aging Kanji Hippocampus Recall Storage Ability

챌린지

Write down five things you did yesterday. Then, translate that sentence into Japanese using 'kiokuryoku' to describe how hard or easy it was to remember those things.

어원

The word is a Sino-Japanese (Kango) compound. 'Ki' (記) comes from the idea of making a mark or record. 'Oku' (憶) combines the heart radical with a sound element meaning 'thought' or 'recollection'. 'Ryoku' (力) is the character for a plow, symbolizing physical strength or power. Together, they form a modern term for cognitive capacity.

원래 의미: The ability to record and hold thoughts in the heart/mind.

Japonic (Sino-Japanese vocabulary)

문화적 맥락

Be careful when discussing 'kiokuryoku' with the elderly in Japan, as a decline in memory is a sensitive topic related to the fear of dementia (ninshishō).

In the West, 'memory' is often seen as a static thing you 'have'. In Japan, 'kiokuryoku' emphasizes that it is a 'power' that can be trained, like a muscle.

Detective Conan: Often features characters with exceptional kiokuryoku. The Memory Police (Yōko Ogawa): A novel exploring the loss of memory and objects. Nintendo Brain Age: A game series that popularized the term 'kiokuryoku' among the general public.
