Hello! I’m Miyabi from Japan Phrase Adventure, a Japanese learning site.
Today, we’ll explore a Japanese expression that many learners find tricky: 「〇〇そう」. I’ll explain it with clear examples so you can really feel how it works.

The Three Stages: Expectation vs. Reality vs. Memory
In Japanese, we change the ending of an adjective depending on whether we are guessing based on appearance, experiencing it right now, or remembering it later.
The structure looks like this
[Adjective Stem] + Sou → [Standard Adjective] → [Past Tense]
Let’s look at some “I-adjectives”
• 寒そう Samu-sou (Looks cold) → 寒い Samui (It is cold) → 寒かった Samukatta (It was cold)
• 怖そう Kowa-sou (Looks scary) → 怖い Kowai (It is scary) → 怖かった Kowakatta (It was scary)
When do we use “~Sou”?
We use “~Sou” when we haven’t experienced something yet but are making a guess or prediction based on what we see. It’s like saying “It looks…” or “It seems…” in English.
Example: At a Restaurant
Before eating
You see a beautiful dish. You haven’t tasted it yet, but it looks delicious. You say: “おいしそう!Oishisou!” (It looks delicious!)
While eating
You are tasting the food right now. You say: “おいしい!Oishii!” (It is delicious!)
After eating
You’ve finished the meal and are looking back on it. You use the past tense: “おいしかった!Oishikatta!” (It was delicious!)
This applies to both I-adjectives and Na-adjectives.
Using I-Adjectives Example: A Public Restroom
Outside
You see an old, run-down building and guess the inside isn’t great: “汚そう Kitanasou” (It looks dirty).
Inside
You step in and confirm your suspicion: “Kitanai” (It is dirty!).
After leaving
You tell your friend: “汚かった Kitanakatta” (It was dirty).
Using Na-Adjectives
The same rule applies to Na-adjectives. Let’s look at two examples:
1.Genki (Healthy/Energetic)
Expectation
You meet a friend after a long time. Based on their bright smile, you think: “元気そう Genki-sou” (They look well).
Experience
You talk to them and confirm they are doing great: “元気だ Genki da!” (They are well!).
Memory
On your way home, you think: “元気だったGenki datta” (They were doing well).
2. Majime (Serious/Diligent)
Expectation
You see a new recruit at work. Based on their appearance, you think: “真面目そう Majime-sou” (They look hardworking).
Experience
You work together and realize they truly are diligent: “真面目だ Majime da!” (They are hardworking!).
Memory
Later, you reflect: “真面目だった Majime datta” (They were hardworking).
The “Kawaii” Trap: One Important Exception!
There is one specific adjective you must be careful with: “可愛い Kawaii” (Cute).
If we followed the grammar rules we just learned, you would say “可愛そう Kawaisou” to mean “looks cute.” However, Japanese people do NOT use “Kawaisou” this way.
Why?
Because there is a completely different word in Japanese: “Kawaisou” (可哀想).
This word means “pitiful,” “poor thing,” or “pathetic.” It has nothing to do with being “cute.”
Imagine you have a cool friend, and you want to guess that his new girlfriend is probably cute. If you say:
“Kimi no kanojo wa kawaisou da ne!”
You are trying to say “Your girlfriend must be cute,” but your friend will hear: “Your girlfriend is so pitiful/pathetic.” That could lead to a big misunderstanding!
What should you say instead?
To avoid this confusion, Japanese people use other expressions to predict “cuteness,” such as
• “Kawaii darou ne” (She’s probably cute, right?)
• “Zettai kawaii!” (I bet she’s definitely cute!)
• “Kawaii to omou” (I think she’s cute.)
Summary
Did today’s lesson help you understand the “~Sou” form a bit better?
Remember
1. ~Sou = Looking/Guessing
2. Standard = Present Experience
3. ~Katta / ~Datta = Past Reflection
4. Avoid “Kawaisou” unless you want to express pity!

That’s all for today. See you next time!
