When learning Japanese, many people first learn the word:

• 匂い（におい / nioi） = smell

But Japanese actually has several words related to smell, and each one carries a different nuance.

Let’s explore some common ones!

---

1. 匂い（におい） — General “Smell”

匂におい is the most neutral and common word.

It can refer to:

• good smells
• bad smells
• or just “a smell” in general

Examples:

• いい匂においがする。
  “It smells good.”
• なんか変へんな匂においがする。
  “Something smells strange.”
• カレーの匂におい！
  “The smell of curry!”

Originally, 匂におい had a more positive nuance long ago, but nowadays it’s fairly neutral.

2. 香り（かおり） — Pleasant Fragrance / Aroma

香かおり sounds softer, elegant, and pleasant.

It’s usually used for:

• flowers
• coffee
• tea
• perfume
• shampoo
• incense

Examples:

• コーヒーの香かおりが好すきです。
  “I like the aroma of coffee.”
• 花はなの香かおり。
  “The fragrance of flowers.”
• この香水こうすいは上品じょうひんな香かおりですね。
  “This perfume has an elegant fragrance.”

Compared to 匂におい, 香かおり feels more refined and beautiful.

3. 臭い（におい / くさい） — Bad Smell

Here’s where learners get confused!

臭い can be read:

• におい
• or くさい

When used as a noun:

• 臭い（におい） = odor / stink

When used as an adjective:

• 臭い（くさい） = smelly / stinky

Examples:

• 靴くつが臭くさい。
  “My shoes stink.”
• いやな臭においがする。
  “There’s a nasty smell.”

This word almost always has a negative nuance.

4. Aroma-Like Expressions Japanese People Use

Japanese also uses many expressions connected to smell.

香ばしい（こうばしい）

A roasted, savory smell.

• パンの香こうばしい香かおり
  “The delicious roasted aroma of bread”

---

生臭い（なまぐさい）

A raw fishy smell.

• 魚さかなが生臭なまぐさい。
  “The fish smells fishy.”

---

汗臭い（あせくさい）

Smelling like sweat.

• 汗臭あせくさいシャツ
  “A sweaty-smelling shirt”

---

香水くさい（こうすいくさい）

“Too much perfume smell.”

Sometimes Japanese adds:

• 〜くさい

to mean:

• “smells strongly like ~”
• “has the vibe of ~”

Not always literally about smell either!

5. “Smells Like…” Can Also Mean “Seems Suspicious”

Japanese often uses smell words metaphorically.

Example:

• なんかあやしい匂においがする。
  “Something feels suspicious.”

Nobody is literally smelling danger 😆
It means:

“I have a bad feeling about this.”

Another common one:

• 犯罪はんざいの匂においがする。
  “It smells like a crime.”

Very dramatic detective-movie energy.

6. Fun Cultural Note 🌸

Japan has a strong culture around seasonal and subtle scents.

People appreciate:

• the smell of rain
• tatami mats
• incense
• seasonal flowers
• fresh rice
• even the scent of different seasons

That’s why words like:

• 香かおり
• 香こうばしい
• 木きの香かおり (smell of wood)

appear often in advertisements and daily life.

Smell is deeply connected to atmosphere in Japanese culture.
