Have you ever felt like someone was exaggerating a little, or that a situation wasn’t as extreme as they made it sound?
Or maybe you’ve been surprised by how strongly someone reacted to something?

In Japanese, one very natural way to express this sense of degree, “that much,” “so much,” or “like that”, is with そんなに (sonna ni).
It’s an N4-level adverb that lets you talk about how big, intense, strong, or surprising something is.

You’ll hear it constantly in everyday conversations, especially when you want to say that something is “not that big of a deal,” when you’re surprised by someone’s reaction, or when you want to confirm how strong or intense something really is.

Let’s explore そんなに together!

💡 Common Usage Patterns:

It can be used in both positive and negative sentences, but it appears especially often with negatives.

💡 こんなに (konna ni) vs そんなに (sonna ni) vs あんなに (anna ni)

When talking about degree in Japanese, そんなに (sonna ni) often appears together with こんなに (konna ni) and あんなに (anna ni). They all mean “this much / that much,” but the nuance depends on distance, physical, emotional, or conversational.

こんなに (konna ni) - “this much,” close to the speaker
Used when talking about something the speaker personally feels, experiences, or is physically near.

こんなに暑いの？
konna ni atsui no?
It’s THIS hot? (I feel it right now.) 

そんなに - “that much,” related to the listener or the topic
Used when referring to the listener’s situation, or something already mentioned in the conversation.

そんなに心配しなくてもいいよ。
sonna ni shinpai shinaku temo ii yo.
You don’t have to worry that much.

あんなに (anna ni) - “that much (over there),” distant or extreme
Used for things far from both people, or situations that feel very intense or surprising.

あんなに人が並んでいるなんてびっくり！
anna ni hito ga narande iru nante bikkuri!
I can’t believe there are THAT many people in line!

💡 Quick Tip

こんなに(konna ni) - close to me (the speaker)
そんなに(sonna ni) - close to you (the listener) or the topic
あんなに(anna ni) - far from both / surprising / extreme

The distance rules for こんなに(konna ni) / そんなに(sonna ni) / あんなに(anna ni) are the same as これ(kore) / それ(sore) / あれ(are).
