At the A1 level, you don't need to use '意志' (ishi) often. You usually use simpler words like 'たい' (want to) or 'つもり' (plan to). However, you might hear it in very simple phrases like '意志が強い' (strong-willed) to describe a character in a story. Think of it as a very strong 'I will' instead of just 'I want'. It's about having a strong heart that doesn't give up. For now, just remember that 'ishi' means a strong mind or will.
At the A2 level, you can start using '意志' to describe people's personalities. For example, '田中さんは意志が強い人です' (Mr. Tanaka is a strong-willed person). You might also see it in simple compound words like '意志力' (willpower). It's helpful for talking about habits, like trying to wake up early or studying every day. It's a noun, so you use it with particles like 'が' or 'の'.
At the B1 level, you should understand the difference between '意志' (willpower) and '意思' (intention). You will use '意志' in more complex sentences to discuss goals and determination. For example, '自分の意志で決める' (to decide by one's own will). You'll also encounter it in formal contexts like school or work when discussing '意志の疎通' (communication/mutual understanding). It's a key word for expressing personal agency and resolve.
At the B2 level, you are expected to use '意志' in abstract discussions about society, philosophy, or literature. You should be familiar with collocations like '意志を貫く' (to carry out one's will) and '意志を固める' (to firm up resolve). You will see it in news reports about the 'will of the people' (国民の意志) or in psychological texts about 'free will' (自由意志). You should be able to distinguish it clearly from synonyms like '意欲' or '決意'.
At the C1 level, you should master the nuanced use of '意志' in professional and academic writing. This includes understanding its role in legal and philosophical discourse. You'll use it to describe complex human motivations and the structural 'will' of organizations. You should be able to discuss the nuances of '意志薄弱' (weak-willed/infirmity of purpose) and how it differs from simple laziness. Your usage should reflect a deep understanding of the word's weight and formal tone.
At the C2 level, '意志' is a tool for precise expression in high-level rhetoric. You can use it to discuss the 'Will to Power' (権力への意志) in Nietzschean philosophy or the 'General Will' (一般意志) in political science. You understand its etymological roots and can use it to articulate subtle distinctions in human agency, fate, and determination. You are comfortable using it in any register, from poetic literature to dense legal contracts, recognizing the historical and cultural weight the word carries.

意志 در ۳۰ ثانیه

  • 意志 (Ishi) refers to human will and determination, emphasizing the mental strength to follow through on decisions.
  • It is commonly used with adjectives like 'strong' (強い) or 'weak' (弱い) to describe a person's character.
  • Unlike 'intent' (意思), '意志' specifically highlights the 'willpower' aspect of the mind's desire.
  • In Japanese culture, having a 'strong 意志' is a highly respected trait associated with success and resilience.

The Japanese word 意志 (いし - ishi) is a foundational noun that encapsulates the concept of human will, volition, and the mental power to carry out a decision. Unlike simple desires (wanting something), 意志 represents a structured, determined mental state directed toward a specific goal. It is the 'engine' of human action, often described in psychological and philosophical contexts as the faculty by which a person decides on and initiates a course of action.

Core Essence
The internal drive or 'backbone' that supports long-term commitment and decision-making.
Grammatical Role
Primarily used as a noun, often paired with verbs like 'to have' (がある), 'to strengthen' (を固める), or 'to respect' (を尊重する).

「彼は強い意志を持って、その難関に立ち向かった。」

— Translation: He faced that difficult barrier with a strong will.

In a broader sense, 意志 is what differentiates a reactive response from a proactive choice. When you use this word, you are highlighting the agency of the individual. It is frequently used in discussions about self-improvement, leadership, and overcoming adversity. The nuance is one of 'resolve'—a firm determination that is not easily swayed by external circumstances or internal fluctuations in mood.

「自分の意志で道を選ぶことが大切だ。」

— Translation: It is important to choose your path by your own will.

Furthermore, 意志 is often associated with the concept of 'free will' (自由意志 - jiyū ishi) in philosophy. It suggests a level of consciousness where one is fully aware of their choices and the consequences thereof. In literature and media, a character with 'strong 意志' is usually the protagonist who refuses to give up despite overwhelming odds, making it a highly positive attribute in Japanese culture.

Visualizing the Kanji
意 (I) means mind/thought, and 志 (Shi) means aspiration/ambition. Together, they represent a mind directed toward a high purpose.

Using 意志 correctly requires understanding its common collocations. It is rarely used in isolation; instead, it functions as the subject or object of specific action-oriented verbs. The most common way to describe someone's character is by using the adjectives 'strong' (強い) or 'weak' (弱い).

  • 意志が強い (Ishi ga tsuyoi): Strong-willed; determined.
  • 意志が弱い (Ishi ga yowai): Weak-willed; easily influenced.
  • 意志を固める (Ishi o katameru): To make up one's mind; to firm up one's resolve.
  • 意志を貫く (Ishi o tsuranuku): To carry out one's will to the end.

「ダイエットを最後まで続けるには、固い意志が必要だ。」

— Translation: To stick to a diet until the end, a firm will is necessary.

In formal writing or business, 意志 is used to express organizational or personal commitment. For example, '意志の疎通' (ishi no sotsū) refers to the mutual understanding or communication of intentions between two parties. However, note that in legal contexts, 意思 is often preferred for 'intent'.

When describing a group, you might say '意志決定' (ishi kettei), which means 'decision-making'. This is a standard term in corporate environments. The process involves gathering '意志' from various stakeholders to reach a consensus.

「リーダーには、迅速な意志決定能力が求められる。」

— Translation: A leader is required to have the ability to make quick decisions (will-based decisions).

You will encounter 意志 in a variety of settings, ranging from daily conversations about personal goals to high-level philosophical debates. In anime and manga, it is a staple word used by protagonists to declare their resolve to protect their friends or achieve their dreams.

In Sports
Coaches often talk about the '意志' of the players to win, emphasizing mental toughness over physical skill.
In Business
Used in '意志決定' (decision making) and when discussing a company's vision or '意志' to expand into new markets.

「国民の意志を政治に反映させるべきだ。」

— Translation: The will of the people should be reflected in politics.

In psychological contexts, 意志 is discussed in relation to self-control and 'willpower' (意志力 - ishiryoku). You might hear it in self-help seminars or read it in books about habit formation. It is also a key term in legal discussions regarding 'testamentary will' (though often written as 遺言, the underlying concept is the deceased's 意志).

「彼は最後まで戦うという強い意志を見せた。」

— Translation: He showed a strong will to fight until the very end.

The most frequent mistake learners (and even native speakers) make is confusing the three homophones: 意志, 意思, and 遺志. While they all sound like 'ishi', their meanings and kanji are distinct.

意志 (Ishi)
Focuses on determination and willpower. Use this for personal goals and inner strength.
意思 (Ishi)
Focuses on intent and communication. Use this for 'intention to buy', 'mutual understanding', or legal 'intent'.
遺志 (Ishi)
Specifically refers to a dying wish or the will of someone who has passed away.

❌ 「意思が強い」 (Incorrect for 'strong-willed')
✅ 「意志が強い」 (Correct)

Another mistake is using 意志 when you simply mean 'plan' (予定 - yotei) or 'hope' (希望 - kibō). 意志 is much heavier and implies a moral or mental commitment. If you just plan to go to the store, don't use 意志.

Several words share a semantic field with 意志, but they differ in intensity and context. Understanding these nuances will help you sound more natural.

決意 (Ketsui)
Determination/Resolution. This is the act of making a firm decision. 意志 is the state of having that will.
意欲 (Iyoku)
Will/Eagerness/Motivation. This is more about the 'desire' or 'drive' to do something, often used in work or learning contexts (e.g., 学習意欲).
志 (Kokorozashi)
Ambition/Aspiration. This is a long-term, high-level goal or mission in life.

「彼は医者になるという高いを持っている。」

— Translation: He has a high ambition to become a doctor.

While 意志 is the internal power, 覚悟 (Kakugo) is the 'readiness' or 'resolution' to face negative consequences. If you are 'prepared for the worst', you use 覚悟, not 意志.
