火傷

The Japanese word 火傷 (yakedo) is a noun that specifically refers to a burn or a scald. In the Japanese linguistic landscape, this term is the primary way to describe skin damage caused by heat, whether that heat comes from a dry source like a hot stove or a wet source like boiling water. Unlike English, which often distinguishes between a 'burn' (dry heat) and a 'scald' (moist heat), Japanese uses yakedo as an umbrella term for both, making it an essential part of daily vocabulary for safety, cooking, and medical contexts. When you touch a hot frying pan, you get a yakedo. When you accidentally spill hot tea on your lap, you also get a yakedo.

Literal Meaning

The kanji are composed of 'Fire' (火) and 'Injury/Wound' (傷). Together, they literally translate to 'fire injury.'

Beyond the literal physical injury, yakedo is frequently used in metaphorical contexts to describe 'getting burned' in a non-physical sense. For example, if someone takes a risky gamble in business or a precarious romantic endeavor and ends up suffering a significant loss or emotional pain, Japanese speakers will say they 'suffered a burn.' This versatility makes the word a B1-level staple because it bridges the gap between basic physical descriptions and more nuanced, figurative language. It is a word that carries a sense of warning and caution, often appearing in safety manuals, kitchen instructions, and medical advice columns.

In a professional medical setting, you might hear the term kashou, which uses the same kanji but the On-yomi (Chinese-derived) reading. However, in 99% of daily interactions—whether talking to a doctor, a friend, or a pharmacist—yakedo is the standard choice. It is also important to note the distinction between yakedo and hiyake (sunburn). While both involve heat damage to the skin, hiyake is specifically reserved for UV radiation from the sun, whereas yakedo covers thermal, chemical, or electrical burns. If you tell someone you have a yakedo on your shoulders after a day at the beach, they might think you actually touched a hot grill rather than just staying out too long in the sun.

Register Note

Neutral to Informal: yakedo suru. Formal/Medical: yakedo wo ou.

The word is also deeply embedded in Japanese idioms. One common saying is 'yakedo wo suru mae ni te wo hiku,' which means to withdraw before getting burned (getting out of a dangerous situation early). Understanding this word requires more than just knowing it means 'burn'; it requires understanding the cultural emphasis on safety and the specific ways Japanese people categorize injuries. In a country where hot tea and communal baths (onsen) are ubiquitous, the risk of a yakedo is a common topic of conversation, making this word highly frequent in domestic life.

Grammatical Category

Noun, Suru-verb (when followed by 'suru').

Using 火傷 (yakedo) correctly involves understanding its role as a noun and its transformation into a verb. The most common construction is [Part of Body] ni yakedo wo suru. This directly translates to 'to do a burn on [body part],' which effectively means 'to burn [body part].' For example, if you burn your finger, you would say 'Yubi ni yakedo wo shimashita.' It is less common to use 'yakedo' as a direct object without the particle 'ni' specifying the location, although 'yakedo wo suru' on its own is perfectly fine to mean 'to get a burn' in a general sense.

Common Verb Pairings

Suru (to do/get), Ou (to sustain - formal), Naoru (to heal), Hiyasu (to cool down).

Another important aspect is the degree of the burn. In English, we say 'first-degree burn,' 'second-degree burn,' etc. Japanese follows a similar logic using the counter do (degree). A first-degree burn is dai-ichido yakedo. However, in casual conversation, people usually just describe the severity with adverbs like hidoi (terrible) or karui (light). If you have a minor scald from steam, you might say 'Karui yakedo deshita' (It was a light burn). If it's a serious injury requiring a hospital visit, 'Hidoi yakedo wo oimashita' (I sustained a severe burn) would be appropriate.

When warning others, the phrase yakedo ni chuui (caution: burns) is ubiquitous on product packaging, heat-generating appliances, and in commercial kitchens. This is a noun-based warning. If you want to tell a child to be careful, you would say 'Yakedo suru yo!' (You'll get burned!). The grammatical flexibility of yakedo allows it to function as a warning, a diagnosis, and a description of an accident all with very slight modifications to the surrounding particles and verbs.

In the realm of figurative language, yakedo is used to describe the consequences of risky behavior. If a friend is about to invest all their money in a suspicious cryptocurrency, you might warn them, 'Sonna koto wo shitara yakedo suru zo' (If you do something like that, you'll get burned). This usage mirrors the English metaphorical 'get burned,' making it intuitive for English speakers to adopt, provided they remember that the Japanese version remains a noun + verb construction.

Negative Form

Yakedo shinai (don't get burned). Example: 'Yakedo shinai you ni, tebukuro wo hamete.' (Wear gloves so you don't get burned.)

Finally, let's look at the passive and causative forms. While you can say 'yakedo saseru' (to cause someone a burn), it is much more common to use the active 'yakedo wo saseru' or describe the action specifically (e.g., 'atsui mono wo hippari-dashite yakedo saseta'). In medical reports, you will see 'yakedo' used as a standalone noun to categorize the injury type in lists of symptoms. This comprehensive range of usage—from the kitchen to the stock market to the hospital—illustrates why mastering yakedo is a milestone in Japanese proficiency.

One of the most common places you will encounter 火傷 (yakedo) is in the Japanese kitchen. Whether you are watching a cooking show like 'Today's Menu' (Kyou no Ryouri) or reading a recipe on Cookpad, the risk of yakedo is a constant theme. Chefs often warn viewers about 'abura-hane' (oil splashing) which causes yakedo. In a Japanese household, parents will constantly tell children 'Atsui kara yakedo suru yo!' (It's hot, so you'll get burned!) when approaching the stove or a hot pot of miso soup. This domestic frequency makes the word part of the 'living vocabulary' of any Japanese speaker.

Public Safety

Vending machines for hot coffee often have a small sticker that says 'Yakedo ni chuui' (Beware of burns) near the dispensing slot.

In public spaces, particularly at onsen (hot springs) or sento (public baths), you might see signs warning about the temperature of the water. While onsen water is meant to be hot, some 'kansen' (source springs) can be scalding. Signs will read 'Kouon ni tsuki yakedo no osore ari' (Due to high temperature, there is a fear/risk of burns). Similarly, in the winter, the use of kairo (disposable heat packs) and yutambo (hot water bottles) leads to a specific type of injury called teion yakedo (low-temperature burns). This happens when a relatively mild heat source is left against the skin for a long time, and it is a very common topic on news programs during the colder months.

In the workplace, particularly in manufacturing or construction, yakedo is a key term in 'Anzen Eisei' (Safety and Health) training. Workers are taught how to handle chemicals or hot machinery to prevent yakedo. If an accident occurs, the worker must report the 'yakedo no teido' (the degree of the burn) to their supervisor. You will also hear this word in pharmacies. When you walk in with a red mark on your skin, the pharmacist might ask, 'Yakedo desu ka? Sore tomo mushi-sare desu ka?' (Is it a burn? Or an insect bite?).

Common Audio Cues

'Atsu-tsu!' (Ouch, hot!) followed immediately by 'Yakedo shita kamo!' (I might have burned myself!).

Lastly, in the context of beauty and grooming, yakedo is mentioned regarding hair irons and curling tongs. Tutorials on YouTube often include tips on how to avoid yakedo on the forehead or ears while styling hair. This broad spectrum of situational usage—from the industrial floor to the beauty salon—demonstrates that yakedo is not just a medical term, but a fundamental word for navigating daily life safely in Japan.

The most frequent mistake English speakers make with 火傷 (yakedo) is confusing it with hiyake (sunburn). In English, 'burn' covers both fire and sun. In Japanese, they are strictly separated. If you say 'Umi de yakedo shimashita' (I got a burn at the sea), people will assume you touched a hot boat engine or a grill, not that you forgot your sunscreen. Always use hiyake for the sun and yakedo for heat sources. This is a classic 'false friend' in terms of conceptual categorization.

Mistake #1: Sunburn vs. Heat Burn

Using 'yakedo' for sun damage. Correct: 'Hiyake' (sun-tan/sun-burn).

Another common error involves particle usage. Many learners try to use 'yakedo' as a direct verb like 'burn' in English (e.g., 'I burned the meat'). In Japanese, yakedo is an injury to living tissue. If you overcook a steak or toast, you don't 'yakedo' it; you kogasu (to scorch/burn food). Saying 'Niku wo yakedo saseta' sounds like you are anthropomorphizing the meat and saying it suffered a medical injury. For food, always use kogeru (to get burnt) or kogasu (to burn something).

A third mistake is using the wrong verb with the body part. In English, we say 'I burned my hand.' In Japanese, the most natural way is 'Te ni yakedo wo shita' (I did a burn on my hand). Using 'Te wo yakedo shita' is also used, but 'ni' is very common when focusing on the location of the injury. Furthermore, learners often forget that yakedo is a noun. You cannot say 'Te wo yakedo-ta.' You must say 'yakedo shita.'

Mistake #2: Object vs. Person

Using 'yakedo' for a house fire or a burnt piece of paper. Use 'moeru' (to burn/glow) or 'kaji' (fire accident) instead.

Finally, watch out for the reading. While the kanji are 火 (ka) and 傷 (shou), the common reading is the irregular yakedo. Many advanced learners who rely on On-yomi rules might accidentally say 'kashou' in a casual conversation. While technically correct in a medical sense, it sounds overly clinical and slightly strange in a normal chat. Stick to yakedo for everyday life to sound more natural and approachable.

To truly master 火傷 (yakedo), you must understand how it fits into the broader family of words related to 'burning' and 'injuries.' Japanese is very precise about the source and result of heat damage. The most important distinction is between yakedo and hiyake (sunburn), which we've discussed. But there are others, like kashou (the medical term for burn) and shoushou (an even more formal term for thermal injury).

Comparison: Yakedo vs. Hiyake

Yakedo: Caused by hot objects/liquids. Hiyake: Caused by the sun. Both involve skin redness, but the source changes the word.

Then there is the verb kogeru (to be scorched/charred). This is what happens to your toast or the bottom of a pot of rice. While yakedo focuses on the pain and injury to a person, kogeru focuses on the physical transformation of an object due to heat. If you are cooking and say 'Niku ga yakedo shiteiru,' it sounds like the meat is in pain. You should say 'Niku ga kogeteiru' (The meat is charring).

Another related word is funshou (frostbite), which is essentially a 'cold burn.' While not using the 'fire' kanji, it occupies the same mental category of 'skin damage from temperature extremes.' In terms of general injuries, yakedo is a type of kizu (wound/cut/injury). If you aren't sure what kind of injury someone has, you can ask 'Kizu wa daijoubu?' (Is the wound okay?), but if you see it's from heat, yakedo is the specific term to use.

Comparison: Yakedo vs. Moeru

Yakedo: The injury to the skin. Moeru: The act of something being on fire. You get a 'yakedo' because something is 'moeteiru'.

Lastly, consider tadare (inflammation/soreness). A severe yakedo can lead to tadare. While yakedo is the event and the initial injury, tadare describes the raw, inflamed state of the skin afterwards. Understanding these nuances helps you describe your physical state accurately to a doctor or pharmacist, ensuring you get the right treatment, like yakedo-gusuri (burn ointment).
