What Does 高い (Takai) Mean in Japanese?
Hiragana: たかい
Romaji: takai
Word type: い-adjective (i-adjective)
Main meanings: high, tall, expensive
Japanese dictionaries use 高い broadly for things that are physically, numerically, socially, or abstractly above a reference point.
高い山 — a high/tall mountain
Human height
背が高い — tall
Price
値段が高い — expensive / high-priced
Number or degree
気温が高い — the temperature is high
Abstract level
能力が高い — highly capable / have strong ability
English chooses high, tall, or expensive according to the noun. Japanese often keeps 高い and lets the surrounding word show the intended meaning.
The Core Image of 高い: “Above a Standard”
The original and most concrete use of 高い concerns spatial height: something is above a reference surface or extends far upward.
From that physical image, the meaning expands to prices, numbers, levels, ranks, ability, and other measurable or imaginable scales.
A point is above a physical standard
↓
A number is above the usual level
↓
A price, temperature, pitch, ability, or probability is high
Core image: above a reference point
A cheap price is low on the scale. A large price is high on the scale.
That is why 値段が高い literally means “the price is high” and naturally translates as “expensive.”
高い Meaning 1: “High”
Use 高い when something is located high, reaches high, or has a high numerical or abstract level.
Physical Position or Height
山が高い。
Yama ga takai.
The mountain is high.
このビルはとても高いです。
Kono biru wa totemo takai desu.
This building is very tall.
棚が高すぎます。
Tana ga takasugimasu.
The shelf is too high.
The Japanese adjective remains 高い. The English translation changes to fit the noun.
High Numbers or Levels
今日は気温が高いです。
Kyō wa kion ga takai desu.
The temperature is high today.
この仕事は難易度が高い。
Kono shigoto wa nan’ido ga takai.
This task has a high level of difficulty.
成功する可能性が高いです。
Seikō suru kanōsei ga takai desu.
There is a high possibility of success.
彼女は能力が高い。
Kanojo wa nōryoku ga takai.
She is highly capable.
高い Meaning 2: “Tall”
When talking about a person, Japanese normally says:
Hiragana: せがたかい
Romaji: se ga takai
Meaning: tall; to be tall
背 (se) refers to a person’s stature, back, or height. The expression therefore says that the person’s stature is high.
兄は背が高いです。
Ani wa se ga takai desu.
My older brother is tall.
あの背が高い人は誰ですか？
Ano se ga takai hito wa dare desu ka?
Who is that tall person?
For a person’s height, include 背が:
田中さんは背が高いです。
Without it, 田中さんは高い sounds incomplete or may invite a different interpretation depending on context.
Why Does Japanese Say 背が高い?
Japanese often describes a person by making a body part or attribute the grammatical subject.
As for Mr. Tanaka, his stature is high.
⇒ Mr. Tanaka is tall.
田中さんは目が大きい。
As for Mr. Tanaka, his eyes are big.
⇒ Mr. Tanaka has big eyes.
田中さんは髪が長い。
As for Mr. Tanaka, his hair is long.
⇒ Mr. Tanaka has long hair.
背が高い人
背の高い人
Both mean “a tall person.”
高い Meaning 3: “Expensive”
When 高い describes a product, service, fee, or price, it usually means expensive or high-priced.
この時計は高いです。
Kono tokei wa takai desu.
This watch is expensive.
ホテル代が高かったです。
Hoteru-dai ga takakatta desu.
The hotel charge was expensive.
この店は少し高いです。
Kono mise wa sukoshi takai desu.
This restaurant/store is a little expensive.
In an ordinary conversation about shopping or restaurants, it usually means “This place is expensive.”
To focus on the building’s height, say something clearer such as この建物は高い or このビルは高い.
Do You Need to Say 値段が高い?
値段が高い literally means “the price is high” and makes the price meaning completely explicit.
This bag is expensive.
このかばんは値段が高い。
The price of this bag is high.
このかばんは高すぎる。
This bag is too expensive.
Use 値段が高い when you want to explicitly discuss the price itself.
Is 高い Rude When Talking About a Price?
高い is not a rude word. However, saying it loudly in front of a seller can sound blunt, just as saying “That’s expensive!” can in English.
高い！
Expensive!
Softer:
ちょっと高いですね。
It is a little expensive, isn’t it?
Polite refusal:
少し予算を超えています。
It is a little over my budget.
Polite decision:
少し考えます。
I will think about it.
For a softer response, use 私には少し高いです—“It is a little expensive for me.”
How to Pronounce 高い (Takai)
Hiragana: たかい
Romaji: takai
Morae: た・か・い
Pronounce each mora clearly:
A short “ta” sound.
か (ka)
A short “ka” sound.
い (i)
A clear “ee” vowel, but not excessively long.
The final い belongs to the adjective ending and should remain audible.
How to Write Takai in Kanji, Hiragana, and Katakana
Hiragana: たかい
Katakana: タカイ
Kanji reading: 高 = たか in 高い
On-reading in compounds: こう (kō)
高い is the standard spelling. The kanji carries the lexical meaning, while the hiragana い is the adjective ending.
たかい is also correct and appears in children’s materials or text written for beginners.
タカイ may appear for emphasis in manga, advertising, or informal visual design, but it is not the normal spelling.
The stem is 高-, and the ending changes when the adjective conjugates: 高い, 高く, 高かった, 高くない.
How to Conjugate 高い
高い is an い-adjective, so its final い changes according to tense and polarity.
高い — is high/tall/expensive
Present negative
