What is the difference between the words sora (空) and ten (天) – sky?

In Japanese, there is the word sora (空) which can be literally translated as sky or void, and there is also the word ten (天) which can be translated as sky, but what is the difference between the two? In this article, we will try to understand the differences and meanings of each of these words.

If you are an English student, you might think that the difference is the same as the word sky and heaven, where one is the literal sky and the other is the spiritual sky. But in Japanese? Is it the same? We can say yes and no.

What does SORA 空 mean?

The kanji sora or kuu (空) has several meanings beyond sky; it can also mean void, vacuum, air, etc. With this kanji, we form words such as:

• 空気 – kouki – Air, atmosphere
• 空港 – kuukou – Airport
• 空間 – kuukan – Space, airspace
• 空軍 – kuugun – Air force, aviation

We can see that the word sora leans more towards the side of space, of emptiness. The sky is a large empty space, and that makes a lot of sense.

What does TEN 天 mean?

The ten or ama (天) can be used to write several words related to the spiritual sky, paradise, or symbolic, see some examples below:

• 天国 – tengoku – This word literally means paradise, kingdom of heaven;
• 天使 – tenshi – Means angel

But the kanji 天 is also used to write words such as:

• 天皇 – tennou – Emperor
• 天気 – tenki – Weather
• 天文 – tenmon – Astronomy

We can note that the kanji 天 is used to refer to grand and sovereign things like sky, weather, or emperor. It even has a relation to the ideogram dai 大 which means big.

What is the difference between 空 and 天?

So the differences between these 2 kanji are that sora (空) gives the idea of space, void while ten (天) gives the idea of greatness, vastness, power, etc.

So it is not easy to state a significant difference between these two words. Not to mention that there are many other words using different ideograms with the same meanings of skies, paradises, angels, etc. You will only know the right moment to use each word when you understand the whole context or have more familiarity with the language.

The Japanese language is a quite complex and simple language at the same time; some things can really confuse our minds, but it has interesting and significant origins and differences.
