解析 解凍する in your Level:

At the A1 level, you only need to know that 解凍 (kaitō) is a word you see on buttons and food packages. Think of it as the 'defrost' button on a microwave. You don't need to worry about complex grammar yet. Just remember that if you see this word on a microwave or a frozen meal, it means you need to wait for it to stop being frozen. It is often paired with 'suru' to make the verb 'to defrost.' For example, 'Niku o kaitō suru' means 'I defrost the meat.' You might see it in a supermarket on labels for fish. If you see '解凍' on a fish label, it means the fish was previously frozen and is now ready to eat. At this stage, focus on recognizing the kanji and knowing it relates to 'frozen things.' It's a very practical word for living in Japan because you will use it every time you cook frozen food. Just think of the '解' as 'opening up' and '凍' as 'ice.' Together, you are opening up the ice to get the food inside!

At the A2 level, you should start using 解凍する (kaitō suru) in simple sentences. You should understand that it is a 'suru' verb and can be used with the '~te kudasai' form to give instructions. For example, 'Kore o kaitō shite kudasai' (Please defrost this). You should also learn the basic compound '自然解凍' (shizen kaitō), which means letting food thaw naturally on the counter. This is common in recipes. You might also encounter it when using a computer in Japanese. If you download a file that ends in .zip, the computer might ask if you want to 'kaitō' (unzip) it. At A2, you are moving from just seeing the word to actually using it to describe your daily routine, like 'I thawed the bread for breakfast.' You should also be able to distinguish it from 'atatameryu' (to warm up). Defrosting is the first step, and warming up is the second step. Learning to say 'Kaitō shite kara, atatamete kudasai' (After defrosting, please warm it up) is a great A2 milestone.

At the B1 level, you should be comfortable using 解凍する (kaitō suru) in both culinary and technical contexts. You should understand the nuance that kaitō is a deliberate action, unlike the natural melting of 'tokeru.' You can now use more complex grammar patterns, such as '~te oku' (to do in advance). For example, 'Ashita no tame ni, niku o kaitō shite okimasu' (I will thaw the meat in advance for tomorrow). You should also be aware of the passive form 'kaitō sareru' and how it appears on food labels in supermarkets to indicate that a product was previously frozen. In an office setting, you should be able to tell a colleague that a file won't unzip: 'Fairu ga kaitō dekimasen.' You are also expected to know related terms like 'reitō' (freezing) and 'asshuku' (compression). At this level, you start to see the word as part of a larger system of vocabulary related to food preservation and data management. You can explain the difference between 'shizen kaitō' and 'renji kaitō' to someone else, showing a deeper understanding of the word's practical applications.

At the B2 level, you should have a firm grasp of the kanji and the more technical nuances of 解凍する (kaitō suru). You should be able to discuss the quality of food after thawing, using terms like 'umami' or 'shokkan' (texture). For instance, you might explain that 'Kaitō no shikata ni yotte, aji ga kawarimasu' (The taste changes depending on the thawing method). In a professional IT environment, you should understand the difference between kaitō and tenkai (expansion/deployment), and be able to read technical manuals that use these terms. You might also encounter the word in more metaphorical or formal contexts, such as 'shisan no kaitō' (thawing of frozen assets) in a news report about economics or international sanctions, although this is less common than the literal meanings. You should be able to use the word fluently in conversation without pausing to think about the difference between it and 'tokeru.' Your ability to use kaitō correctly in a business email—perhaps explaining that a password is required to unzip a sensitive document—is a hallmark of B2 proficiency.

At the C1 level, your understanding of 解凍する (kaitō suru) should extend to its most formal and specialized uses. You can appreciate the nuances in culinary literature where different types of 'kaitō' (like 'teion kaitō' - low-temperature thawing) are debated for high-end ingredients like bluefin tuna. You should be able to read and discuss economic or legal articles where 'kaitō' refers to the lifting of a freeze on bank accounts or diplomatic relations, understanding the gravity of the term in those contexts. In the digital realm, you might understand the underlying algorithms of 'asshuku' and 'kaitō' and be able to discuss them using technical Japanese. You can also use the word with sophisticated grammar structures to express subtle meanings, such as 'Kaitō sareta to wa ie...' (Even though it was thawed...). Your vocabulary is rich enough to choose between kaitō, yūkai, and tenkai with perfect precision based on the register and subject matter. You are not just using the word; you are mastering its place within the complex web of Japanese technical and formal language.

At the C2 level, you possess a native-like intuition for 解凍する (kaitō suru). You can use it in creative writing or high-level oratory, perhaps using it metaphorically to describe the 'thawing' of a long-standing emotional distance between characters or nations. You understand the historical development of the word, from its roots in physical thawing to its modern adaptation for computer science. You can effortlessly switch between extremely casual kitchen talk and high-level technical or economic discourse. You might even be able to discuss the etymology of the kanji characters '解' and '凍' and how their combination reflects a broader East Asian linguistic approach to describing state changes. There is no context—whether it's a complex software installation error, a legal battle over frozen assets, or a delicate culinary process—where you would be unsure of how to use or interpret this word. You have reached a level where the word is no longer a 'vocabulary item' but a versatile tool for precise and nuanced communication in any field of human endeavor.

解凍する 30秒了解

Used for defrosting frozen food in the kitchen.
Used for unzipping/extracting compressed computer files.
It is a transitive 'suru' verb (Object + を + 解凍する).
Different from 'tokeru' (natural melting like ice or snow).

The Japanese verb 解凍する (kaitō suru) is a compound verb consisting of two kanji characters: 解 (kai), meaning to untie, solve, or unravel, and 凍 (tō), meaning to freeze or ice. When combined, they literally translate to 'unraveling the freeze' or 'solving the frozen state.' In practical, everyday Japanese, this word is primarily used in two distinct contexts: the culinary world and the digital world. In the kitchen, it refers to the process of defrosting or thawing frozen food. Whether you are taking a piece of steak out of the freezer or heating up a frozen bento meal, you are performing the act of kaitō. In the digital realm, however, the word takes on a technical meaning: to decompress or 'unzip' a compressed file (such as a .zip or .lzh file). This dual usage makes it an essential word for both domestic life and office environments in Japan.

Culinary Context: Used when moving food from a frozen state to a usable room-temperature or chilled state. It is a transitive verb, meaning you usually 'thaw something.'

冷凍の鶏肉を冷蔵庫でゆっくり解凍するのが一番美味しいです。 (Thawing frozen chicken slowly in the refrigerator is the most delicious way.)

Japan has a highly developed 'Reishoku' (frozen food) culture. From high-quality frozen ramen to intricate bento side dishes, the instruction 解凍してお召し上がりください (please thaw and enjoy) is seen on countless packages. There are several ways to thaw food in Japan: 自然解凍 (shizen kaitō - natural thawing at room temperature), 流水解凍 (ryūsui kaitō - thawing under running water), and レンジ解凍 (renji kaitō - microwave thawing). Each method is chosen based on the type of food and the time available. For instance, sashimi is often thawed slowly in the fridge to maintain its texture, while a quick lunch might require the microwave's defrost setting.

Digital Context: In IT and office work, this refers to extracting files from a compressed archive. The opposite action, compressing a file, is called 'asshuku' (圧縮).

送られてきたZIPファイルを解凍するためのパスワードを教えてください。 (Please tell me the password to unzip the ZIP file you sent.)

The word is extremely common in professional emails. If you receive a large set of documents, they will likely be compressed to save space. Knowing how to use kaitō suru in this context is vital for working in any Japanese-speaking office. It is worth noting that while English users might say 'unzip' or 'extract,' Japanese users almost exclusively use kaitō or sometimes tenkai (展開 - to expand/deploy), though kaitō remains the most colloquial standard for compressed archives.

Kanji Breakdown: 解 (Kai): To untie, solve, or explain. 凍 (Tō): To freeze. Together, they imply the systematic removal of a frozen state to return something to its original, usable form.

この肉は、まだ完全に解凍されていません。 (This meat hasn't been completely defrosted yet.)

Using 解凍する (kaitō suru) correctly requires understanding its role as a transitive verb. In most cases, you are the agent performing the action on an object (the food or the file). The grammatical structure usually follows: [Object] + を + 解凍する. However, in passive contexts, such as describing the state of something, you might use 解凍される (to be thawed) or 解凍されている (is thawed/in a thawed state). Because it is a 'suru' verb, it is highly flexible and can be used in polite form (解凍します), negative form (解凍しない), or potential form (解凍できる).

Everyday Cooking: When talking about meal prep, the timing of the thawing is crucial. You will often hear sentences that combine 'kaitō' with time-related adverbs.

夕食のために、朝から冷凍の魚を解凍しておきました。 (I thawed the frozen fish since this morning for dinner.)

In this sentence, kaitō shite okimashita uses the ~te oku grammar point, which means to do something in advance. This is a very common way to use the word, as thawing is almost always a preparatory step. You might also see it used with conditions: 解凍しすぎると、肉の旨味が逃げてしまいます (If you thaw it too much/too aggressively, the flavor of the meat will escape). This highlights the nuance that kaitō is a process that requires care to maintain quality.

Instructions and Commands: Recipes and food packaging use the imperative or instructional forms. 'Kaitō shite kudasai' is the standard polite request.

電子レンジの解凍モードを使って、2分間加熱してください。 (Please heat it for 2 minutes using the microwave's defrost mode.)

Notice here that 解凍 is used as a noun modifying 'mode' (解凍モード). This is a very common compound noun. Other compounds include 解凍方法 (kaitō hōhō - thawing method) and 解凍時間 (kaitō jikan - thawing time). If you are looking at a Japanese microwave, the button for defrosting will simply say 解凍. Understanding this noun usage is just as important as the verb usage.

IT and Workplace Communication: In the office, you might need to explain that you cannot open a file or ask someone to unzip one for you.

このソフトをインストールする前に、まずフォルダを解凍する必要があります。 (Before installing this software, you first need to unzip the folder.)

In a technical context, kaitō is often paired with hitsuyō ga aru (there is a necessity) or shite kudasai. If a file is corrupted and won't unzip, you might say 解凍できません (cannot unzip/thaw). Using the word in this way shows a high level of functional Japanese, as it bridges the gap between daily life and professional skills. Remember, whether it's frozen shrimp or a compressed database, the action of 'opening it up for use' is kaitō.

You will encounter 解凍する (kaitō suru) in several key environments in Japan. The most frequent place is undoubtedly the kitchen. Japanese households rely heavily on frozen ingredients due to the high frequency of grocery shopping and the small size of many refrigerators. Consequently, daily conversations often revolve around dinner preparation. You might hear a family member ask, 'Did you thaw the meat?' (Niku, kaitō shite oite kureta?). It is also a staple word in TV cooking shows and YouTube recipe videos, where chefs explain the best way to maintain the 'umami' of frozen ingredients during the thawing process.

Supermarkets and Convenience Stores: Labels on food packaging are the most common written form you will see. Look for '解凍' on labels for frozen seafood or pre-made meals.

ラベルに「解凍」と書いてある魚は、一度冷凍されたものです。 (Fish with 'thawed' written on the label are those that were frozen once.)

In Japanese supermarkets, fish that was previously frozen and then thawed for sale must be labeled as 解凍 (kaitō). This is an important distinction for consumers who may want to avoid refreezing the item at home. Seeing this word on a price tag or label tells you about the history and freshness of the product. Similarly, convenience store staff might use the word when heating up a frozen item for you, though they usually use the more general atatamemasu ka? (shall I warm it up?).

The Modern Office: Whenever data is shared, 'kaitō' is likely to be mentioned. It is the standard term for handling compressed attachments in emails.

添付ファイルを解凍したら、中身を確認してください。 (Once you have unzipped the attached file, please check the contents.)

In a professional setting, you will hear this during meetings or see it in Slack/Teams messages. If a colleague sends a 'LZH' or 'ZIP' file, they might follow up with, 'Did you manage to unzip it?' (Kaitō dekimashita ka?). This usage is so ingrained that many Japanese speakers don't even think of the 'ice' connection when unzipping a file; it has become a pure technical term. For IT support staff, kaitō is a daily-use word when troubleshooting software installations or data transfers.

Home Appliances: The interface of Japanese electronics. Microwave ovens, refrigerators with 'thaw' compartments, and specialized kitchen gadgets.

最新の冷蔵庫には、肉を美味しく解凍する専用のスペースがあります。 (The latest refrigerators have a dedicated space for deliciously thawing meat.)

When shopping at an electronics store like Yodobashi Camera or Bic Camera, you will see kaitō all over the signage for kitchen appliances. Salespeople will explain the 'thawing performance' (kaitō seinō) of different microwave models. They might demonstrate how a specific 'steam defrost' function works. For anyone living in Japan, the word is literally written on the buttons of the machines they use every single day to prepare food.

One of the most common mistakes for English speakers learning Japanese is confusing 解凍する (kaitō suru) with other verbs that mean 'to melt' or 'to dissolve.' While English often uses 'melt' for many different scenarios, Japanese is much more specific. The most frequent confusion is with 溶ける (tokeru). While both involve a transition from solid to liquid (or semi-solid), they are used in very different contexts and have different grammatical properties.

Kaitō vs. Tokeru: 'Kaitō suru' is a deliberate process of thawing something for use. 'Tokeru' is the natural process of melting (like ice in the sun or salt in water).

❌ 氷を解凍してください。 (Please 'thaw' the ice.)
✅ 氷を溶かしてください。 (Please melt the ice.)

In the example above, using kaitō for plain ice sounds very strange. You 'thaw' food to prepare it, but you 'melt' (tokasu - transitive version of tokeru) ice to turn it into water. Another common error is using kaitō for things that aren't frozen to begin with. For example, if you are dissolving sugar in tea, you must use tokasu (溶かす), never kaitō. Kaitō strictly requires the object to have been intentionally frozen (reitō) beforehand.

The Transitive Trap: Students often forget that 'kaitō suru' is transitive. If the meat is thawing on its own, you should use 'kaitō sarete iru' or 'tokete iru' depending on the focus.

❌ 肉が解凍しました。 (The meat 'thawed' - sounds like the meat performed the action.)
✅ 肉が解凍されました。 (The meat was thawed.)

While in English we can say 'The meat is thawing,' in Japanese, kaitō suru feels very much like an action someone does. If you want to describe the state of the meat being ready, kaitō ga owatta (thawing has finished) or mō tokete iru (already melted/thawed) are more natural. This distinction between 'action' and 'state' is a hurdle for many B1-level learners.

IT Vocabulary Confusion: Sometimes learners use 'hiraku' (to open) when they should use 'kaitō suru' for zip files.

ファイルを開く前に、まず解凍しなければなりません。 (Before 'opening' the file, you must first 'unzip' it.)

While you 'open' (hiraku) a folder or a document, you 'thaw/unzip' (kaitō) the compressed archive. If you tell a Japanese colleague 'I can't open the file' (fairu ga hirakemasen), they might think there's a permission issue. If you say 'I can't unzip it' (kaitō dekimasen), they will know exactly what the technical problem is. Being precise with kaitō avoids confusion in a professional setting.

To truly master 解凍する (kaitō suru), it is helpful to look at its synonyms and related terms. Depending on the level of formality or the specific context (scientific, culinary, or technical), other words might be more appropriate. Understanding these nuances will help you sound more like a native speaker and allow you to understand more complex texts.

融解する (Yūkai suru): This is a scientific and highly formal term for melting or fusion. You will see this in physics or chemistry textbooks rather than the kitchen.

氷の融解熱を測定する。 (Measure the heat of fusion of ice.)

While kaitō is about making food ready to eat, yūkai is about the physical change of state from solid to liquid. You would never use yūkai for a ZIP file or a frozen steak in a casual conversation. However, if you are reading a report about global warming and the 'melting' of polar ice caps, yūkai is the word you will encounter.

溶かす (Tokasu) / 溶ける (Tokeru): The most common everyday alternatives. 'Tokeru' is intransitive (it melts), and 'tokasu' is transitive (I melt it).

バターをフライパンで溶かしてください。 (Please melt the butter in the frying pan.)

Wait, can you use tokasu for frozen meat? Yes, in casual speech, people often say niku o tokasu. However, kaitō is more precise and sounds slightly more 'proper.' Tokasu is more about the result (becoming soft or liquid), while kaitō is about the process of reversing the freezing. For chocolate or butter, tokasu is the only choice, as they aren't 'frozen' in the culinary sense of long-term storage.

展開する (Tenkai suru): In IT, this means 'to expand' or 'to deploy.' It is often used for extracting software packages or expanding data structures.

圧縮されたデータをメモリ上に展開する。 (Expand the compressed data into the memory.)

While kaitō is the common word for a user unzipping a file, tenkai is more technical and refers to the system's action of expanding data. If you are writing code or technical documentation, tenkai might be more appropriate. For a general user interface, kaitō is friendlier. Understanding this distinction helps in navigating Japanese software and technical manuals.

How Formal Is It?

趣味小知识

The use of 'kaitō' for computer files only started in the late 1980s when compression software became popular in Japan. It was a perfect metaphor for 'unfreezing' a packed file.

Common in daily life (cooking) and work (IT).

常见错误

Using 'kaitō' for melting sugar. → 砂糖を溶かす (satō o tokasu)
Sugar is not 'frozen', so it cannot be 'thawed'. Use 'tokasu' for dissolving or melting.
Saying 'Niku ga kaitō shita'. → 肉が解凍された (Niku ga kaitō sareta)
Kaitō is transitive. The meat doesn't thaw itself; it 'is thawed' by someone or something.
Confusing 'kaitō' (thaw) with 'kaitō' (answer). → Use context and kanji.
While they sound similar, you 'thaw' meat but 'answer' a question. The kanji are completely different.
Using 'kaitō' for ice cream melting on a hot day. → アイスが溶ける (Aisu ga tokeru)
Natural melting of something that shouldn't be melted is 'tokeru'. 'Kaitō' is a deliberate process.
Writing '凍' with three dots on the left. → 凍 (Two dots for ice)
The 'ice' radical (冫) has two strokes. The 'water' radical (氵) has three. Ice is frozen water, so it has fewer 'drops'!

小贴士

Transitive Usage

Always remember that 'kaitō suru' takes an object with 'o'. You are the one doing the thawing!

The 'Ice' Radical

Notice the two strokes on the left of '凍'. This is the 'ice' radical. Don't add a third stroke or it becomes the 'water' radical!

IT Context

If you work in a Japanese office, 'kaitō' is one of the top 10 technical words you will use every week for email attachments.

Semi-Thawing

Learn 'han-kaitō' (half-thawing). It's the secret to slicing meat perfectly thin for dishes like Sukiyaki!

Read the Labels

Look for the characters '解凍' in the fish section. It helps you know if the fish is fresh or previously frozen.

Defrost Button

Locate the '解凍' button on your Japanese microwave as soon as you move in. It's usually near the start button.

Warm Relationships

You can use 'kaitō' poetically to describe a cold relationship becoming warm again. It's a very beautiful usage.

Don't say 'melt' for files

In English, we say 'unzip'. In Japanese, never say 'tokasu' for files. Only 'kaitō' or 'tenkai'.

Long Vowels

The 'ō' in 'tō' is long. Practice saying 'ka-i-to-o' to get the timing right before speeding it up.

Legal/Economic Use

When reading news about sanctions, 'shisan kaitō' means unfreezing assets. It's high-level but useful for JLPT N1.

记住它

记忆技巧

Think of 'Kai' as 'Key' and 'Tō' as 'Toe'. You need a key to unlock your frozen toes! Or, 'Kai' (solve) the 'Tō' (frozen) mystery.

视觉联想

Imagine a block of ice with a zipper on it. When you unzip it, the ice disappears and food comes out. That is 'kaitō'.

Word Web

冷凍 (reitō) 解凍 (kaitō) 圧縮 (asshuku) 電子レンジ (microwave) 自然 (nature) ファイル (file) 肉 (meat) ZIP

挑战

Go to your kitchen and find one item in the freezer. Say out loud in Japanese: 'Kore o kaitō shimasu' (I will thaw this). Then, unzip a file on your computer and say 'Fairu o kaitō shimasu'.

词源

Composed of Middle Chinese-derived kanji. 'Kai' (解) originally depicted hands taking apart an ox's horns, meaning 'to divide' or 'to solve'. 'Tō' (凍) depicts ice (冫) and the phonetic 'east' (東).

原始含义： To melt ice or release something from a frozen state.

Sino-Japanese (Kango).

文化背景

No specific sensitivities, but be careful not to use it for 'melting' people's bodies in a macabre sense; stick to 'tokeru' for natural processes.

English speakers often use 'thaw' and 'melt' interchangeably for food, but Japanese speakers are much more likely to use 'kaitō' specifically for anything previously 'reitō' (frozen).

Generally, no. For ice cream, use 'tokeru' (it's melting) or 'tokasu' (I'm melting it). 'Kaitō' implies you are restoring something to a usable state from storage, whereas melting ice cream is usually seen as a negative or natural change.

No, it is used for any compressed archive format, including .lzh, .rar, .7z, and .tar.gz. It is the generic Japanese term for 'decompressing' or 'unextracting' files.

In the kitchen, it is 'reitō' (冷凍 - freezing). In IT, it is 'asshuku' (圧縮 - compression). Both are essential partner words to learn alongside 'kaitō'.

No, 'kaitō' only means the ice has been removed. You usually need to 'kanetsu' (heat) or 'ryōri' (cook) the food afterward, unless it's something like sashimi.

It's a metaphor. A compressed file is 'frozen' (packed tightly and unusable), and you need to 'thaw' it (unravel the compression) to access the contents inside.

It means 'natural thawing'. You leave the frozen item at room temperature or in the fridge to let it thaw on its own without using a microwave or water.

It is a standard word used in both formal (IT/Business) and informal (Home/Kitchen) settings. It is neither particularly slangy nor overly stiff.

You can say 'Kono fairu o kaitō dekimasen' or 'Kaitō ni shippai shimashita' (I failed at unzipping).

In casual talk, you might hear 'niku o tokasu', but 'kaitō' is more precise and common in recipes and professional contexts.

It means 'thawed product'. This tells the customer that the fish or meat was previously frozen and should probably not be refrozen at home.
