How do you say "I see" in Japanese?

Quick use

Use そうなんですね (sou nan desu ne) when you want to show that you understood or are following what the other person said.

It is useful as a soft response when you do not have a full reply yet.

Chunk or pattern

• This is a fixed phrase.
• Learn the whole line first.
• It works mainly as a conversation response, not as a sentence you need to analyze deeply.

Practical note

This does not strongly mean “I agree.” It is closer to “Oh, I see” or “I didn’t know that.”
