Definition and meanings of “kochira koso”

Let me start with the definition and meanings of “kochira koso”.

• kochira koso – こちらこそ : a Japanese phrase meaning ‘thank you, too’, ‘you, too’, ‘me, too’, ‘my pleasure, too’, or such in Japanese.

Japanese native speakers use this phrase as a very useful response. They use this when they want to mean the same thing as someone has just said but in the opposite (or different) direction. So, this is very similar to the English phrases like ‘you, too’, ‘me, too’, and so on. Of course, this can also mean ‘thank you, too’, ‘my pleasure, too’, or such depending on the context and situation.

The definition and meanings are not that difficult, I think. To understand this phrase more clearly, however, let me explain its grammatical components in detail, one by one.

What does “kochira koso” literally mean in Japanese?

Grammatically, “kochira koso” consists of the following two components:

• kochira – こちら : a demonstrative pronoun used to politely refer to something close to the speaker. In the phrase, this is used to politely refer to the speaker’s side.
• koso – こそ : a binding particle used to strongly emphasize the preceding word.

These two components tell us that “kochira koso” is literally a strongly emphasized expression for ‘my side’. This literal interpretation is not completely in line with the actual meanings, but still very understandable, I think. Japanese native speakers use this phrase as a response to say, for example, “what you said now should’ve come from my side.”
