Hello, I’m Kodak.
Someone gives you an instruction in Japanese. You understand it and want to answer:
“Okay.”
“I understand.”
“Got it.”
Should you say わかった (wakatta) or わかりました (wakarimashita)?
わかった = casual “Got it.”
わかりました = polite “I understand.”
わかった (wakatta) is the casual past form of わかる (wakaru: to understand). Use it with friends, family members, and people you speak casually with.
わかりました (wakarimashita) is the polite past form. Use it with teachers, unfamiliar people, coworkers in polite conversation, and in many everyday service or workplace situations.
Both can mean “I understand,” “I got it,” “Okay,” or “All right.”

What Does Wakatta Mean in Japanese?

Romaji: wakatta
Meaning: I understand; I got it; okay; all right; I found out
わかった is the casual past form of わかる (wakaru), meaning “to understand,” “to become clear,” or “to find out.”
As a response, it often works like the English expressions:
“Okay.”
“I understand.”
“All right.”
あとで電話してね。
Ato de denwa shite ne.
Call me later, okay?わかった。
Wakatta.
Okay. / Got it.
“Your message has now become clear to me.”
↓
“I understand.” / “Got it.”
What Does Wakarimashita Mean in Japanese?
Hiragana: わかりました
Kanji: 分かりました
Romaji: wakarimashita
Meaning: I understand; understood; okay; certainly
わかりました is the polite past form of わかる. The ending ～ました makes the sentence polite.
明日は9時に来てください。
Ashita wa ku-ji ni kite kudasai.
Please come at nine tomorrow.はい、わかりました。
Hai, wakarimashita.
Yes, understood. / Okay.
The Japan Foundation’s beginner materials introduce わかりました as a practical response meaning “I understand”, including situations where a learner confirms that they understood information or instructions.
It is a normal everyday expression you can use with a teacher, a stranger, a coworker, or someone you do not speak casually with.

Why Are Wakatta and Wakarimashita in the Past Tense?
The dictionary form is わかる. Its past forms are:
わかった ⇒ understood / became clear — casual
わかりました ⇒ understood / became clear — polite
When someone explains something, your state changes:
I do not understand.
↓
The information becomes clear.
↓
わかった／わかりました
“I now understand.” / “Got it.”
わかる！ can mean “I know what you mean!” or “I can relate!”
But after receiving an instruction, Japanese speakers more often say わかった or わかりました to show that the message has been received.
The Core Image and Origin of Wakaru
The modern verb わかる means that a meaning, fact, difference, or situation becomes clear.
Historically, わかる also had the sense of things becoming divided or separated. This is connected to 分かれる (wakareru), “to divide” or “to separate.”
↓
They become separated and distinguishable
↓
Their meaning or difference becomes clear
↓
わかる = to understand / to become clear
When the parts of a confusing situation become clear and distinguishable, you can say わかる.
How to Pronounce Wakatta and Wakarimashita
Romaji: wakatta
Morae: 4
わかりました: わ・か・り・ま・し・た
Romaji: wakarimashita
Morae: 6
The Small っ in Wakatta
The small っ creates a brief pause before た.
wa-ka-(pause)-ta
Do not pronounce it as:
わかた (wakata)
However, the Japanese spelling remains わかりました, and beginners should practice all six morae.
Kanji, Hiragana, and Katakana
わかった
わかりました
Common kanji and kana:

Both the hiragana and 分 spellings are common. In casual messages, manga, subtitles, and beginner materials, you will often see わかった written entirely in hiragana.

Best with friends and close people.
わかりました
Polite “I understand.”
A safe everyday polite response.
了解／了解しました
“Roger,” “understood,” or “noted.”
Common among teammates and coworkers, but the appropriate level depends on the relationship and workplace culture.
承知しました
“Understood” or “I acknowledge your request.”
More formal and professional than わかりました.
かしこまりました
“Certainly.” / “Of course.”
Highly polite and deferential; especially common in customer service.

When serving a customer, かしこまりました is the most deferential choice.
Is Wakarimashita Polite Enough?
Yes, in many ordinary situations. It is a standard polite expression, and official Japanese-language materials use it as a beginner-level response to information and instructions.
It is important not to memorize the oversimplified rule that わかりました is always rude to a superior. The relationship, setting, workplace culture, and degree of formality all matter.

Can be natural and appropriate.

Common Beginner Mistakes
Mistake 1: Using Wakatta with Everyone
わかった is casual. Use わかりました when the rest of your conversation uses polite です／ます forms.
Mistake 2: Translating Every English “OK” as Wakatta
Use わかった when “OK” acknowledges information or an instruction. Use expressions such as 大丈夫 or いい when something is acceptable or permitted.
Mistake 3: Saying Wakarimasu After an Explanation
I understand / I can understand — possible in some contexts, but not the usual acknowledgment after receiving a new instruction.
○ わかりました。
I understand now. / Got it.
Mistake 4: Assuming Past Tense Always Means Past Time
わかりました often describes a change that has just happened: the information has become clear, so the speaker now understands.
Mistake 5: Saying Wakatta Too Sharply
A short わかった with a flat or irritated voice can sound like “I heard you—stop telling me.” Adding うん, よ, or a friendly tone can soften it.
Yeah, got it.
わかったよ。
Okay, I understand.
はい、わかりました。
Yes, understood.
