Using 〜にくい & 〜やすい in Japanese

Have you ever struggled to say that something is easy or difficult to do in Japanese? Whether you want to describe how simple a task is or express frustration over something challenging, 〜にくい (nikui) and 〜やすい (yasui) are essential grammar patterns that make your Japanese sound more natural.

In Japanese, we often use these structures to talk about actions and experiences:

Usage: When to Use 〜にくい and 〜やすい in Sentences

Now that we’ve seen some common expressions, let’s dive into when and how to use 〜にくい and 〜やすい in different situations. These grammar patterns help describe the ease or difficulty of performing an action, and they are frequently used in everyday Japanese.

1. Describing How Easy or Difficult an Action Is

One of the most common uses of 〜にくい and 〜やすい is to describe how easy or difficult it is to perform an action. This structure is often used with verbs.

✅ やすい Example:

この本は読（よ）みやすいです。
Kono hon wa yomi yasui desu.
→ This book is easy to read.

❌ にくい Example:

この漢字は書（か）きにくいです。
Kono kanji wa kaki nikui desu.
→ This kanji is difficult to write.

2. Talking About Physical Ease or Difficulty

These patterns can also be used to describe how physically easy or hard something is to handle or use.

✅ やすい Example:

Kono pasokon wa mochi yasui desu.
→ This laptop is easy to carry.

❌ にくい Example:

このドアは開（あ）けにくいです。
Kono doa wa ake nikui desu.
→ This door is hard to open.

3. Expressing Emotional or Psychological Difficulty

Sometimes, 〜にくい is used for things that are emotionally difficult to do, such as asking a sensitive question or speaking in an unfamiliar language. 〜やすい, on the other hand, can describe situations that feel comfortable or natural.

✅ やすい Example:

彼（かれ）は話（はな）しやすい人（ひと）です。
Kare wa hanashi yasui hito desu.
→ He is an easy person to talk to.

❌ にくい Example:

この話題（わだい）は言（い）いにくいです。
Kono wadai wa ii nikui desu.
→ This topic is hard to talk about.

4. Referring to Visibility or Legibility

Both 〜にくい and 〜やすい can describe how easy or hard something is to see, read, or understand.

✅ やすい Example:

このフォントは読（よ）みやすいです。
Kono fonto wa yomi yasui desu.
→ This font is easy to read.

❌ にくい Example:

この地図（ちず）は見（み）にくいです。
Kono chizu wa mi nikui desu.
→ This map is hard to see.

These are some of the most common situations where 〜にくい and 〜やすい are used in Japanese. In the next section, we’ll break down the conjugation rules so you can start forming your own sentences correctly.

Conjugation: How to Attach 〜にくい and 〜やすい to Different Words

Now that we’ve covered the usage, let’s learn how to correctly attach 〜にくい and 〜やすい to different types of words. These patterns are typically used with verbs, but they can also modify nouns and adjectives in some cases.

1. Verbs: How to Attach 〜にくい and 〜やすい

〜にくい and 〜やすい attach to the ます-stem (also known as the verb stem).

How to find the verb stem:

Take the dictionary form of a verb (e.g., 食べる, 飲む, 書く).
Remove the ます from the polite ます-form (e.g., 食べます → 食べ, 飲みます → 飲み).
Attach 〜にくい or 〜やすい to the remaining stem.

Conjugation Examples for Different Verb Types:

Verb Type	Dictionary Form	ます-Form	Stem	+ にくい (Hard to…)	+ やすい (Easy to…)
Ichidan (る-verbs)	食べる (taberu)	食べます (tabemasu)	食べ (tabe)	食べにくい (tabe nikui) → Hard to eat	食べやすい (tabe yasui) → Easy to eat
Godan (う-verbs)	飲む (nomu)	飲みます (nomimasu)	飲み (nomi)	飲みにくい (nomi nikui) → Hard to drink	飲みやすい (nomi yasui) → Easy to drink
Godan (う-verbs)	書く (kaku)	書きます (kakimasu)	書き (kaki)	書きにくい (kaki nikui) → Hard to write	書きやすい (kaki yasui) → Easy to write
Irregular Verbs	する (suru)	します (shimasu)	し (shi)	しにくい (shi nikui) → Hard to do	しやすい (shi yasui) → Easy to do
Irregular Verbs	来る (kuru)	来ます (kimasu)	来 (ki)	来にくい (ki nikui) → Hard to come	来やすい (ki yasui) → Easy to come

2. Can 〜にくい and 〜やすい Be Used with Adjectives?

No, 〜にくい and 〜やすい cannot attach to adjectives directly. However, to describe the ease or difficulty of an adjective, you can use 〜そう (sou) or 〜すぎる (sugiru) instead.

✅ Alternative Example with Adjective:

暑（あつ）すぎて眠（ねむ）りにくいです。
Atsu sugite nemuri nikui desu.
→ It’s too hot, so it’s hard to sleep.

If you want to say something looks easy or difficult, use 〜そう (sou) instead.

✅ Example:

この問題（もんだい）は難（むずか）しそうです。
Kono mondai wa muzukashi sou desu.
→ This question looks difficult.

3. Can 〜にくい and 〜やすい Be Used with Nouns?

Technically, 〜にくい and 〜やすい do not attach directly to nouns. However, you can use them indirectly by turning the noun into a verb using する (suru).

✅ Example:

このサイトは利用（りよう）しやすいです。
Kono saito wa riyou shi yasui desu.
→ This website is easy to use.

4. Can 〜にくい and 〜やすい Be Used in Negative Sentences?

Yes, they can! Simply conjugate the 〜にくい and 〜やすい as い-adjectives:

Tense	Example with 〜やすい (Easy to Do)	Example with 〜にくい (Hard to Do)
Present Positive	食べやすい (tabe yasui) → Easy to eat	食べにくい (tabe nikui) → Hard to eat
Present Negative	食べやすくない (tabe yasuku nai) → Not easy to eat	食べにくくない (tabe nikuku nai) → Not hard to eat
Past Positive	食べやすかった (tabe yasukatta) → Was easy to eat	食べにくかった (tabe nikukatta) → Was hard to eat
Past Negative	食べやすくなかった (tabe yasuku nakatta) → Was not easy to eat	食べにくくなかった (tabe nikuku nakatta) → Was not hard to eat

By following these conjugation rules, you can confidently use 〜にくい and 〜やすい in various sentence structures.

In the next section, we’ll explore the grammar rules in more detail to ensure you fully grasp these concepts.

Grammar Rules: Understanding 〜にくい and 〜やすい

Now that we’ve covered usage and conjugation, let’s take a deeper look at the grammar rules behind 〜にくい and 〜やすい. Understanding these rules will help you form correct and natural sentences in Japanese.

1. 〜にくい and 〜やすい Always Modify Verbs

As mentioned earlier, 〜にくい and 〜やすい attach to the verb stem. They cannot be directly attached to adjectives or nouns.

✅ Correct Usage (with Verbs):

漢字（かんじ）は書（か）きにくいです。
Kanji wa kaki nikui desu.
→ Kanji is hard to write.

❌ Incorrect Usage (with Adjectives/Nouns):

この部屋（へや）は寒（さむ）にくいです。 (Incorrect!)
この仕事（しごと）はやすいです。 (Incorrect!)

✅ Correct Alternative:

この部屋（へや）は寒（さむ）すぎて、寝（ね）にくいです。
Kono heya wa samu sugite, ne nikui desu.
→ This room is too cold, so it’s hard to sleep.
この仕事（しごと）は簡単（かんたん）でやりやすいです。
Kono shigoto wa kantan de yari yasui desu.
→ This job is simple, so it’s easy to do.

2. 〜にくい and 〜やすい Are Treated as い-Adjectives

Both 〜にくい and 〜やすい act like regular い-adjectives. This means they can be conjugated just like adjectives.

✅ Example Conjugation with 〜やすい (Easy to Do)

Tense	Sentence Example	Translation
Present Positive	この靴（くつ）は履（は）きやすいです。	These shoes are easy to wear.
Present Negative	この靴（くつ）は履（は）きやすくないです。	These shoes are not easy to wear.
Past Positive	この靴（くつ）は履（は）きやすかったです。	These shoes were easy to wear.
Past Negative	この靴（くつ）は履（は）きやすくなかったです。	These shoes were not easy to wear.

✅ Example Conjugation with 〜にくい (Hard to Do)

Tense	Sentence Example	Translation
Present Positive	このペンは書（か）きにくいです。	This pen is hard to write with.
Present Negative	このペンは書（か）きにくくないです。	This pen is not hard to write with.
Past Positive	このペンは書（か）きにくかったです。	This pen was hard to write with.
Past Negative	このペンは書（か）きにくくなかったです。	This pen was not hard to write with.

3. 〜にくい Does NOT Mean “Impossible”

〜にくい does not mean something is completely impossible to do; it just means that it’s difficult or inconvenient. If you want to express something that is completely impossible, use 〜できない (dekinai) instead.

✅ Example:

この字（じ）は読（よ）みにくいです。
Kono ji wa yomi nikui desu.
→ This character is hard to read. (But still possible!)

❌ Incorrect Usage:

この字（じ）は読（よ）めにくいです。 (Wrong! “Yomeru” means “can read”, so “yome nikui” is incorrect!)

✅ Alternative for “Impossible”:

この字（じ）は読（よ）めません。
Kono ji wa yomemasen.
→ I cannot read this character. (Completely impossible!)

4. 〜にくい vs. 〜づらい: What’s the Difference?

Another similar structure in Japanese is 〜づらい (zurai), which also means “hard to do.” While 〜にくい is more about physical difficulty, 〜づらい is used more for psychological or emotional difficulty.

✅ Example Using 〜にくい (Physical Difficulty):

この薬（くすり）は飲（の）みにくいです。
Kono kusuri wa nomi nikui desu.
→ This medicine is hard to swallow. (Because of taste, texture, etc.)

✅ Example Using 〜づらい (Emotional Difficulty):

彼（かれ）に本当（ほんとう）のことを言（い）いづらいです。
Kare ni hontou no koto o ii zurai desu.
→ It’s hard to tell him the truth. (Because of emotions or sensitivity)

💡 Rule of Thumb:

〜にくい = Physically difficult, inconvenient
〜づらい = Emotionally difficult, uncomfortable

5. 〜やすい Is NOT the Same as 〜がち or 〜やすい (Cheap/Easy)

Be careful not to confuse やすい (yasui = easy to do) with other やすい words in Japanese.

✅ Example Using 〜やすい (Easy to Do):

このボールペンは書（か）きやすいです。
Kono boorupen wa kaki yasui desu.
→ This ballpoint pen is easy to write with.

❌ Confusing Similar Word:

このシャツは安（やす）いです。
Kono shatsu wa yasui desu.
→ This shirt is cheap. (Completely different meaning!)

6. Can 〜にくい and 〜やすい Be Used in Formal Writing?

Yes! Both forms can be used in formal writing, but they are more common in spoken Japanese or casual writing. In business or academic writing, you might see more neutral alternatives like 難（むずか）しい (muzukashii, difficult) or 簡単（かんたん） (kantan, easy).

✅ Example in a Formal Setting:

この手順（てじゅん）は理解（りかい）しやすいです。
Kono tejun wa rikai shi yasui desu.
→ This procedure is easy to understand.

These grammar rules will help you use 〜にくい and 〜やすい correctly in different contexts.

In the next section, we’ll discuss tricky points and exceptions that you need to keep in mind when using these patterns.

Things to Keep in Mind: Tricky Points, Exceptions, and Important Details

Now that you understand the grammar rules for 〜にくい and 〜やすい, let’s look at some tricky points, exceptions, and details that often confuse learners. Paying attention to these will help you use these patterns correctly and sound more natural in Japanese.

1. Some Verbs Change Meaning with 〜にくい and 〜やすい

In some cases, attaching 〜にくい or 〜やすい slightly changes the meaning of the original verb. Instead of simply indicating difficulty or ease, the phrase might imply something unexpected.

✅ Example: 聞（き）く (to listen / to ask)

聞（き）きにくい → Hard to ask (someone something)
- 先生（せんせい）に質問（しつもん）を聞（き）きにくいです。
  Sensei ni shitsumon o kiki nikui desu.
  → It’s hard to ask the teacher a question. (Because of nervousness, shyness, etc.)
聞（き）きやすい → Easy to listen to / easy to hear
- この先生（せんせい）は話（はな）し方（かた）が聞（き）きやすいです。
  Kono sensei wa hanashikata ga kiki yasui desu.
  → This teacher’s way of speaking is easy to listen to.

💡 Notice the difference?

聞きにくい relates to asking questions (psychological difficulty).
聞きやすい relates to listening (ease of hearing).

2. Some Verbs Use 〜づらい Instead of 〜にくい

As mentioned earlier, 〜づらい is often used instead of 〜にくい for psychological or emotional difficulty. While 〜にくい is grammatically correct in most cases, native speakers often prefer 〜づらい for things related to feelings or social interactions.

✅ More Natural Sentences Using 〜づらい:

上司（じょうし）に意見（いけん）を言（い）いづらいです。
Joushi ni iken o ii zurai desu.
→ It’s hard to express my opinion to my boss. (Social/emotional difficulty)
この話（はなし）はしづらいです。
Kono hanashi wa shi zurai desu.
→ This topic is hard to talk about. (Sensitive topic)

💡 When to Use Which?

〜にくい → Physical difficulty (writing, reading, eating, etc.)
〜づらい → Emotional/social difficulty (talking, asking, expressing emotions, etc.)

3. 〜やすい Does Not Mean “Cheap”

One common mistake learners make is confusing 〜やすい (easy to do) with 安（やす）い (cheap). Though they sound the same, their meanings are completely different.

❌ Incorrect:

このレストランは食（た）べやすいです。 (This restaurant is easy to eat?)

✅ Correct:

このレストランの料理（りょうり）は食（た）べやすいです。
Kono resutoran no ryouri wa tabe yasui desu.
→ The food at this restaurant is easy to eat.

If you want to say something is cheap, use 安（やす）い (yasui) instead.

このレストランは安（やす）いです。 (This restaurant is cheap.)

4. Some Expressions Don’t Work Well with 〜にくい or 〜やすい

While 〜にくい and 〜やすい work for most action verbs, they don’t always sound natural for certain abstract or stative verbs.

❌ Unnatural Sentences:

愛（あい）しにくい (Hard to love?)
怒（おこ）りやすい (Easy to get angry?)

✅ Natural Alternatives:

この人（ひと）は理解（りかい）しにくいです。
Kono hito wa rikai shi nikui desu.
→ This person is hard to understand. (Instead of “hard to love”)
彼（かれ）はすぐ怒（おこ）ります。
Kare wa sugu okorimasu.
→ He gets angry easily. (Instead of “easy to get angry”)

5. 〜にくい and 〜やすい Can Be Used with Potential Verbs, But It’s Rare

Although 〜にくい and 〜やすい are usually attached to the stem of a verb, they can be used with potential form verbs, but it’s uncommon.

✅ Rare, But Possible:

この問題（もんだい）は解（と）けやすいです。
Kono mondai wa toke yasui desu.
→ This problem is easy to solve.
彼（かれ）の話（はなし）は信（しん）じにくいです。
Kare no hanashi wa shinji nikui desu.
→ His story is hard to believe.

💡 However, it’s more common to just use the verb in its normal form!

6. When to Use Katakana vs. Hiragana for 〜にくい and 〜やすい

Both 〜にくい and 〜やすい are typically written in hiragana, but you may occasionally see them in katakana (ニクイ / ヤスイ) for emphasis. This is common in advertisements, signs, or marketing materials to make the words stand out.

✅ Example in Advertising:

スープがノミニクイ？ (Is the soup hard to drink?)
切（き）りヤスイ包丁（ほうちょう）！ (An easy-to-cut-with knife!)

However, in normal writing, it’s best to stick with hiragana (にくい / やすい).

These are some of the key tricky points and exceptions to keep in mind when using 〜にくい and 〜やすい. Mastering these details will help you avoid common mistakes and sound more natural in Japanese.

In the next section, we’ll go over common mistakes and how to avoid them.

Common Mistakes and How to Avoid Them

Even though 〜にくい and 〜やすい are straightforward to use, learners often make common mistakes when forming sentences. Let’s look at these errors and learn how to avoid them!

1. Using 〜にくい Instead of 〜づらい for Emotional or Social Difficulty

❌ Incorrect:

先生（せんせい）に「いいえ」と言（い）いにくいです。
Sensei ni “iie” to ii nikui desu.
→ It’s hard to say “no” to my teacher. (Technically correct but sounds unnatural.)

✅ Correct:

先生（せんせい）に「いいえ」と言（い）いづらいです。
Sensei ni “iie” to ii zurai desu.
→ It’s hard to say “no” to my teacher. (More natural because it expresses social/emotional difficulty.)

💡 Tip: Use 〜づらい instead of 〜にくい when talking about psychological or emotional difficulty.

2. Confusing 〜やすい with 安（やす）い (cheap)

❌ Incorrect:

この服（ふく）は着（き）やすいですから、買（か）いました。
Kono fuku wa ki yasui desu kara, kaimashita.
→ (This clothing is easy to wear, so I bought it.) (Sounds okay, but could be misunderstood as “cheap.”)

✅ Correct:

この服（ふく）は着（き）やすいので、買（か）いました。
Kono fuku wa ki yasui node, kaimashita.
→ I bought this clothing because it’s easy to wear. (Using “ので” makes it sound smoother.)

💡 Tip: If you mean cheap, use 安（やす）い, not 〜やすい!

3. Using 〜にくい and 〜やすい with the Wrong Type of Verbs

Since 〜にくい and 〜やすい describe actions, they cannot be used with adjectives or non-action verbs.

❌ Incorrect:

この部屋（へや）は広（ひろ）やすいです。
(Kono heya wa hiro yasui desu.) → (This room is easy to be spacious?)
彼（かれ）は悲（かな）しにくいです。
(Kare wa kanashi nikui desu.) → (He is hard to be sad?)

✅ Correct:

この部屋（へや）は広（ひろ）くて使（つか）いやすいです。
Kono heya wa hirokute tsukai yasui desu.
→ This room is spacious and easy to use.
彼（かれ）は悲（かな）しみを表（あらわ）しにくいです。
Kare wa kanashimi o arawashi nikui desu.
→ He finds it difficult to express sadness.

💡 Tip: Use 〜にくい and 〜やすい with action verbs only!

4. Forgetting to Change Group 1 Verbs to the い-Stem

Since Group 1 verbs (Godan verbs) change their ending vowel before attaching 〜にくい or 〜やすい, forgetting this rule leads to incorrect conjugation.

❌ Incorrect:

この本（ほん）は読（よ）むやすいです。
(Kono hon wa yomu yasui desu.) → (This book is easy to read?)

✅ Correct:

この本（ほん）は読（よ）みやすいです。
Kono hon wa yomi yasui desu.
→ This book is easy to read.

💡 Tip: For Group 1 verbs, change the final う sound to い before attaching 〜にくい or 〜やすい!

5. Forgetting That 〜にくい Does Not Mean “Impossible”

Some learners misunderstand 〜にくい as meaning “impossible”, but it only means “difficult”.

❌ Incorrect:

漢字（かんじ）は読（よ）みにくいから、全然（ぜんぜん）読（よ）めません。
(Kanji wa yomi nikui kara, zenzen yomemasen.)
→ (Kanji is hard to read, so I can’t read it at all.)

✅ Correct:

漢字（かんじ）は読（よ）みにくいけど、練習（れんしゅう）すれば読（よ）めます。
Kanji wa yomi nikui kedo, renshuu sureba yomemasu.
→ Kanji is hard to read, but I can read it if I practice.

💡 Tip: 〜にくい means “difficult,” not “impossible”—don’t overuse it!

6. Using 〜やすい for Something That is “Convenient” Instead of “Easy”

Learners sometimes use 〜やすい to mean “convenient”, but that’s not always correct.

❌ Incorrect:

このコンビニは行（い）きやすいです。
(Kono konbini wa iki yasui desu.) → (This convenience store is easy to go?)

✅ Correct:

このコンビニは近（ちか）くて便利（べんり）です。
Kono konbini wa chikakute benri desu.
→ This convenience store is close and convenient.

💡 Tip: 〜やすい means “easy to do”, not “convenient”—use 便利（べんり） (benri) instead!

7. Using 〜にくい and 〜やすい in Formal Writing

While 〜にくい and 〜やすい are commonly used in spoken and casual written Japanese, they may sound too informal for academic or business writing.

✅ More Formal Alternatives:

〜しにくい → 難（むずか）しい (muzukashii) / 困難（こんなん）な (konnan na)
〜しやすい → 簡単（かんたん）な (kantan na) / 容易（ようい）な (youi na)

💡 Tip: If writing a business email or essay, consider using 難しい / 簡単な instead!

These are some of the most common mistakes learners make with 〜にくい and 〜やすい. By avoiding these errors, you’ll sound more natural and confident in Japanese.

Next, we’ll practice with example sentences to reinforce what you’ve learned!

Summary: Key Takeaways

Here’s a quick recap of everything you learned about 〜にくい and 〜やすい:

✅ Meaning & Function:

〜にくい: Indicates something is difficult or hard to do.
〜やすい: Indicates something is easy or likely to happen.

✅ Usage Situations:

〜にくい is used when an action is physically, mentally, or emotionally difficult.
〜やすい is used when an action is effortless, convenient, or happens often.

✅ Conjugation Rules:

Attach to the stem of a verb:
- 食べにくい (hard to eat), 食べやすい (easy to eat).
Works with all three verb groups in Japanese.

✅ Grammar Rules & Exceptions:

Does NOT describe a person’s ability (use 〜づらい instead).
Can be used for emotions, like 忘れにくい (hard to forget).
Sometimes interchangeable with 〜づらい, but 〜づらい has a stronger nuance of emotional difficulty.

✅ Common Mistakes to Avoid:
❌ Using 〜にくい for likelihood (use 〜やすい instead).
❌ Using 〜やすい for subjective difficulty (use 〜づらい if it’s emotional).
❌ Forgetting that these forms do NOT conjugate like regular adjectives.
