Formal Ways to Say Brightness
When it comes to formal situations or interactions, the following terms are commonly used to express brightness in Japanese:
1. 明るさ (akarusa)
明るさ refers to the brightness of light or the overall level of brightness in a place or object. It can also describe the cheerfulness or liveliness of a person’s character. For instance:
彼女の部屋の明るさは心地よい。
(Kanojo no heya no akarusa wa kokochiyoi.)
The brightness in her room is pleasant.
In this example, 明るさ describes the level of brightness in someone’s room, conveying a positive atmosphere.
2. 輝度 (kidou)
輝度 is commonly used to denote the brightness or luminance of a light source or object. It is often employed in scientific or technical contexts. Here’s an example:
その輝度計は光源の明るさを正確に測定する。
(Sono kidoukei wa kougen no akarusa o seikaku ni sokutei suru.)
That photometer accurately measures the brightness of the light source.
In this case, 輝度 specifically refers to the measurement of brightness using a photometer.
3. 光度 (koudo)
光度 is another formal term used to indicate the brightness or luminous intensity of light. It is often employed in technical discussions, such as in physics or engineering. Consider the following example:
このソーラーパネルの光度は非常に高い。
(Kono so-rapanel no koudo wa hijou ni takai.)
The brightness of this solar panel is exceptionally high.
Here, 光度 describes the luminous intensity of the solar panel, emphasizing its high brightness level.
Informal Ways to Say Brightness
In casual conversations or informal situations, people often use the following terms to express brightness in Japanese:
1. 明るさ (akarusa)
Just like in formal settings, 明るさ can be used informally to describe brightness in everyday conversations. Here’s an example:
この部屋は明るすぎて目が痛いよ。
(Kono heya wa akarusa sugite me ga itai yo.)
This room is too bright; it hurts my eyes.
In this case, 明るさ refers to the excessive brightness causing discomfort to one’s eyes.
2. 光 (hikari)
光 is a simple and commonly used Japanese term that means “light.” It can be employed to express brightness casually. For example:
あの星の光がとても明るいね。
(Ano hoshi no hikari ga totemo akarui ne.)
The light from that star is very bright.
Here, 光 is used informally to describe the brightness of a star.
Tips for Using Brightness-related Terms
Now that you know the various ways to express brightness in Japanese, here are some additional tips to help you use these terms effectively and naturally:

For formal settings or when communicating with someone unfamiliar, it is advisable to use the more formal terms, such as 明るさ, 輝度, or 光度. In informal conversations with friends or peers, the informal terms like 明るさ or 光 can be used more freely.
