I know that a lot of Japanese learners understand “tadaima” as a Japanese phrase for ‘I’m home’. This understanding is correct. Native speakers often say “tadaima” to mean ‘I’m home’ in Japanese. Interestingly, however, it literally means ‘just now’ and doesn’t even contain any word meaning ‘I’, ‘am’, or ‘home’. In this blog post, therefore, I will explain this phrase in detail based on its original expression. My explanations would help Japanese learners to understand this phrase more clearly. Then, let’s get started!

Definition and meaning of “tadaima”

Let me start with the definition and meaning of “tadaima”.

• tadaima – ただいま : a Japanese phrase for ‘I’m home’.

Japanese people use this phrase to announce their arrivals at their homes. So, this phrase can work in the same way as the English phrase, “I’m home”, does.

In addition to this usage, native speakers often use this phrase to say “just now” in Japanese. And interestingly, this is the original usage of this phrase. To understand this point more clearly, let me explain the components of “tadaima” in detail, one by one.

Components of “tadaima”

“Tadaima” consists of the following two words:

• tada – ただ : an adverb used to emphasize the meaning of its following word.
• ima – いま : a noun meaning ‘now’ in Japanese. This can also be written in kanji as “今”, but normally written in hiragana in the phrase.

From these two words, we can understand that “tadaima” literally means ‘just now’ or such in Japanese. So, there is no wonder native speakers use it to say “just now” in Japanese.

When we meet new Japanese phrases, we should check their components in detail to understand their meanings clearly and deeply. In many cases, components tell us a lot about meanings of phrases they form. Actually, here, we could get the better understanding of “tadaima” through the detailed check above.

Then, the question naturally arises: how can “just now” be “I’m home” in Japanese? Let me answer this question by explaining the full version of the phrase.

How can “just now” be “I’m home” in Japanese?

To tell the truth, “tadaima” which announces one’s arrival at home is the shortened version of “tadaima kaerimashita”. Japanese people are very lazy, so often make abbreviations or shortened versions of phrases. “Tadaima” is one invention. Its official version is “tadaima kaerimashita”. Then, the next question arises: what does its second part – “kaerimashita” – mean in Japanese? It can be broken down into the following three words:

• kaeri – 帰り (かえり) : one conjugation of the verb, “kaeru”, which means ‘to come back’, ‘to come home’, or such in Japanese. It has been conjugated for the better connection with its following word.
• mashi – まし : one conjugation of the auxiliary verb, “masu”, which is used after a verb to make it polite. Probably, this is well known as a part of Japanese masu form.
• ta – た : an auxiliary verb used after a verb, adjective, or auxiliary verb to make its past tense form.

From the two words explained already and these three new words, we can understand that “tadaima kaerimashita” literally means ‘just now came home’ politely in Japanese. Again, but Japanese people are very lazy. So, they don’t want to use this long version to announce their arrivals at their homes. They only use the first two words, instead. This is how the phrase, “tadaima”, was invented and how “just now” can be “I’m home’ in Japanese.

Then, let me explain how to use “tadaima” through the example sentence below.

Example: how to say “I’m home” in Japanese

Below are the new words used in the example sentence.

• kyou – 今日 (きょう) : a noun meaning ‘today’ in Japanese. This can also work as an adverb. In the example, this works as a noun.
• wa – は : a binding particle working as a case marker or topic marker. In the example, this works after “kyou” to make the subject word in the sentence.
• isogashikat – 忙しかっ (いそがしかっ) : one conjugation of the i-adjective, “isogashii“, which means ‘busy’ in Japanese. In the example, it has been conjugated for the better connection with the following word.
• ta – た : the same as explained already. This is an auxiliary verb used after a verb, adjective, or auxiliary verb to make its past tense form. In the example, this is used after “isogashikat” to make its past tense form, “isogashikat ta”, which means ‘was busy’ in Japanese.

This is a typical usage of “tadaima”. When we want to say “I’m home” in Japanese, this phrase is the best choice.

Summary

In this blog post, I’ve explained the definition and meaning of “tadaima” and its original expression. And in addition, I’ve explained how to use it through the example sentence. Let me summarize them as follows.

• tadaima – ただいま : a Japanese phrase for ‘I’m home’. Native speakers often use this to announce their arrivals at their homes. So, this can work in the same way as the English phrase, “I’m home”, does. Literally, however, this phrase means ‘just now’ in Japanese.
• tadaima kaerimashita – ただいま帰りました (ただいまかえりました) : the original expression of “tadaima” which is used to announce one’s arrival at home. This literally means ‘just now came home’ politely in Japanese.
