The two commonly used words to say sun in Japanese are “taiyou” (太陽) and “hi” (日). When referring to the sun as a body of our solar system the word “taiyou” (太陽) is more appropriate. “Hi” (日), on the other hand, is used when the sun affects daily life and in words like “sunrise” and “sunset”.

1. Taiyou – More Scientific Word for “Sun” in Japanese

The word taiyou (太陽) translates as “sun” and is one of the two most commonly used words to say sun in Japanese. It comes from the Chinese language and should be used when you want to refer to the sun as a body of our solar system or in a more scientific way.


Most of the time when you use the word “solar” in English it is translated as taiyou (太陽) in Japanese. “Solar system“, for example, is taiyou kei (太陽系), and the word for “solar cell” is taiyou denchi (太陽電池) in Japanese. The list goes on and on and on.

However, the Japanese word taiyou (太陽) can also be used when talking about the sun in normal daily life expressions and sentences like “the shining sun“, “the sun is shining“, “the sun is bright“, etc.

2. Hi – Japanese Word Meaning “Sun”, “Sunshine”, or “Day”

Hi (日) is the original Japanese word for sun but has a couple of translations: sun, sunshine, sunlight, day, days, daytime, etc. It is also one of the most common kanji and used in many other words like nihon (日本, Japan) and nichiyoubi (日曜日, Sunday).


day, days

Whenever you want to talk about the sun in relation to daily life and especially in situations when the sun impacts human lives and activities, this is the word you should use. Since it is a little difficult to explain I recommend you try memorizing the following words and expressions.



Hi ga nobotta.
The sun is up.

Hi ga shizundeita.
The sun has set.

Koori wa hi ni ataru to tokeru.
Ice melts in the sun.

There is another Japanese kanji that you can use for the sun which is 陽 (hi). In contrast to the more commonly used kanji 日 (hi), it is less often used, though, and only translates as “sun“, “sunshine“, and “sunlight“.



3. San – English Loanword Mening “Sun”

Similar to the English loanwordsukai” that you can use to say sky in Japanese, there is also one that you can use for the sun. The word san (サン) is pronounced exactly the same as the English word “sun” and therefore very easy to remember.


However, the loanword san (サン) is usually only found in names for characters or names for places like Nakano Sanplaza (中野サンプラザ), which is a rather big and famous concert hall in Tokyo. Also, since it is an English loanword it is written in katakana only and there is no kanji.

4. Ohisama – Honorific Way to Say “the Sun” in Japanese

Ohisama means “the Sun” or “Honorable Mr. Sun” and can be written in kanji as お日様, 御日様, or お日さま. This term is commonly used by children to refer to the sun in an honorific and respectful way.

5. Otentousama – Even More Honorific Word for “the Sun”

Otentousama, which can also be written as Otentosama or O’tento sama, is another even more honorific word for “the Sun”. In kanji, it is either written as お天道様, 御天道様, or お天道さま. To be honest, I have never heard the word before, so I assume it might only be used in a religious context.
