生ゴミ

Practice it Examples Notes & Tips 生ゴミ in 30 Seconds

Explanation 生ゴミ in your Level:

At the A1 level, you just need to know that 'namagomi' means the food trash you have in your kitchen. You should learn it alongside basic verbs like 'suteru' (throw away). In Japan, trash is very important. You will see signs with this word. If you see '生', it means raw. If you see 'ゴミ', it means trash. Think of it as 'wet trash' from food. You don't need to worry about complex grammar, just remember that food scraps = namagomi.

At the A2 level, you should be able to understand instructions about when to put out your 'namagomi'. You will often see it paired with days of the week, like 'Kayōbi wa namagomi no hi desu' (Tuesday is kitchen waste day). You should also learn the word 'bukuro' (bag) to make 'namagomi-bukuro'. At this level, you are starting to manage your own household in Japanese, so knowing that 'namagomi' needs to be separated from 'purasuchikku' (plastic) is a vital practical skill.

At the B1 level, you can discuss the problems associated with 'namagomi', such as the smell (nioi) or the weight (omosa). You should understand the cultural expectation of 'mizukiri' (draining water) before disposal. You can explain to a neighbor that you missed the collection day or ask for clarification on local rules. You are moving beyond simple identification to describing the process of waste management and the responsibilities of a resident in a Japanese community.

At the B2 level, you can engage in more detailed discussions about environmental issues related to 'namagomi'. This includes 'shokuhin rosu' (food loss) and the efficiency of 'shoriki' (disposal machines). You can understand more technical explanations from the city office about why 'namagomi' must be separated and how it affects the incineration temperature. You should be comfortable using the word in both casual domestic settings and slightly more formal community meetings.

At the C1 level, you have a nuanced understanding of 'namagomi' within the context of Japanese 'mottainai' culture and circular economy initiatives. You can debate the merits of different municipal waste strategies and understand the sociological implications of trash disposal rules on community harmony (wa). You recognize the word in literature or news reports where it might be used metaphorically or as a symbol of domestic reality and urban life challenges.

At the C2 level, you command the full range of vocabulary related to 'namagomi', from the most informal household slang to highly technical environmental engineering terms. You can navigate complex legal documents regarding waste management and contribute to policy discussions. You understand the historical evolution of the word and its kanji/katakana usage, and you can use the term with perfect native-level prosody and cultural appropriateness in any given social or professional context.

Practice it Examples Notes & Tips

生ゴミ in 30 Seconds

生ゴミ (namagomi) specifically refers to organic kitchen waste like food scraps and leftovers, distinct from general trash like paper or plastic.
It is a crucial term for living in Japan because of the country's strict waste separation rules and specific collection days for food waste.
The word emphasizes the 'raw' (nama) nature of the waste, which often involves handling moisture and managing odors in the kitchen.
Commonly paired with verbs like 'suteru' (throw away) and 'dasu' (put out), and often categorized under 'combustible' waste in many cities.

The Japanese term 生ゴミ (pronounced namagomi) is an essential noun for anyone living or traveling in Japan. It literally translates to 'raw trash' or 'fresh garbage,' but its practical application is specifically focused on organic waste originating from the kitchen. This includes food scraps, vegetable peelings, leftover meals, eggshells, and coffee grounds. Understanding this word is crucial because Japan has one of the most rigorous waste disposal systems in the world, and separating your namagomi from other types of waste like plastics or paper is not just a suggestion—it is a social obligation and often a legal requirement enforced by local municipalities.

Literal Composition: The word consists of 'Nama' (生), meaning raw, fresh, or live, and 'Gomi' (ゴミ), the standard word for trash. Together, they describe waste that is biologically active and prone to decomposition.
Everyday Necessity: You will encounter this word daily in household chores, when reading apartment rules, or when looking at the collection schedule (gomi-shushu-bi) posted in your neighborhood. It is the primary concern for odor control in Japanese kitchens.

台所の生ゴミを捨ててください。(Please throw away the kitchen waste in the kitchen.)

A common household request in Japan.

In a broader context, 生ゴミ represents the intersection of Japanese culture and environmental consciousness. Because Japan is a small island nation with limited landfill space, incineration is the primary method of disposal. Since namagomi has a high water content, it requires more energy to burn. Consequently, many modern Japanese households use 'namagomi shoriki' (garbage disposals or composters) to reduce the weight and volume of this waste before it even leaves the home. When you use this word, you aren't just talking about 'trash'; you are talking about a specific category of material that requires careful handling due to its potential to smell and its impact on the waste management cycle.

夏は生ゴミの臭いが気になります。(The smell of kitchen waste is a concern in the summer.)

The word is predominantly used in domestic settings. You won't typically find namagomi bins in public parks or train stations, as those bins are usually for 'combustibles,' 'bottles,' and 'cans.' If you are at a restaurant, the staff handles the namagomi in the back. Therefore, the term carries a domestic, 'behind-the-scenes' nuance. It is the grit of daily life—the remnants of a meal that must be managed to maintain a clean and harmonious living space. Mastering this word means you are ready to participate in the local community as a responsible resident.

Using 生ゴミ correctly involves pairing it with specific verbs that describe the lifecycle of waste management. In English, we might just say 'take out the trash,' but in Japanese, the specificity of the waste type often dictates the verb or the surrounding context. Because namagomi is organic, it is almost always associated with verbs of disposal, cleaning, and odor management.

Common Verb Pairings

Dasu (出す): To put out (for collection). Namagomi o dasu is the standard way to say you are taking the food waste to the designated collection point.
Suteru (捨てる): To throw away. Used when putting scraps into the bin inside the house.
Shori suru (処理する): To process or dispose of. Used when talking about using a machine or a composting system.

生ゴミは火曜日と金曜日に出してください。(Please put out the kitchen waste on Tuesdays and Fridays.)

Typical instruction found in apartment guides.

When describing the physical state of namagomi, adjectives related to smell and moisture are frequent. Words like kusai (stinky), nama-atatakai (lukewarm/unpleasant), or jimejime shita (damp) often accompany discussions about waste, especially during the humid Japanese rainy season (tsuyu). In a sentence, namagomi usually functions as the direct object (followed by the particle 'o') or the subject (followed by 'ga' or 'wa').

この袋に生ゴミをまとめてください。(Please gather the kitchen waste into this bag.)

Advanced learners should note that in technical or environmental discussions, namagomi might be replaced by the more formal shokuhin haikibutsu (food waste). However, in 99% of daily interactions—with neighbors, landlords, or family—生ゴミ is the only word you need. It is polite enough for all standard social situations but informal enough for the home. Using it shows a practical grasp of Japanese life.

If you live in Japan, you will hear 生ゴミ in several specific environments. The most common is the household, where family members coordinate chores. You will also hear it in local community announcements, often broadcast through loudspeakers in rural areas or via posters in urban apartment complexes. These announcements typically remind residents of the rules for 'combustible waste' (moeru gomi), of which namagomi is a major sub-category.

TV and Media: On morning variety shows (wide shō), you will often see segments on 'Life Hacks' (raifu hakku) for dealing with namagomi. These might include using baking soda to neutralize smells or reviews of the latest high-tech 'namagomi shoriki' (garbage processing machines) that dehydrate food scraps to prevent odors.
Supermarkets and Stores: In the cleaning supply aisle, you will see products specifically labeled for namagomi. This includes specialized small bins for the sink (sankaku kōnā) and deodorizing sprays. The word is printed in bold on packaging to indicate that the product is designed to handle the unique challenges of organic waste.

自治会のニュースに、生ゴミの出し方の変更が書いてあります。(The neighborhood association news has a change in how to put out kitchen waste written on it.)

Another place you'll hear it is in discussions about sustainability and 'SDGs' (Sustainable Development Goals), which are very popular in Japan right now. Schools and local governments talk about reducing namagomi to lower the carbon footprint of incinerators. In this context, the word takes on a slightly more serious, civic tone. You might hear a teacher telling students not to leave leftovers (zanpan) because they become namagomi, which is wasteful.

Lastly, you might hear it in complaints. If a neighbor's trash is smelling or attracting crows (a major problem in cities like Tokyo), the word namagomi will be at the center of the grievance. 'Namagomi no kanri' (management of kitchen waste) is a key part of being a 'good neighbor' in Japanese society.

While 生ゴミ seems straightforward, English speakers often make mistakes by either being too broad or too narrow with its application. The most common error is confusing namagomi with the general word for trash, gomi, or with other specific categories like 'combustibles' (moeru gomi).

Mistake 1: Using it for non-organic items: Don't use namagomi for tissues, plastic wrappers, or paper, even if they are 'dirty.' If it didn't come from a plant or animal as food, it's generally not namagomi. Tissues are 'moeru gomi' (burnable trash), but not 'namagomi.'
Mistake 2: Forgetting the 'Raw' nuance: Some learners think namagomi only refers to 'raw' food like uncooked vegetable peels. In reality, it includes cooked leftovers as well. If it's food waste, it's namagomi.

❌ 鼻をかんだティッシュは生ゴミです。
✅ 鼻をかんだティッシュは燃えるゴミです。

Tissues are burnable, but not kitchen waste.

Another mistake involves the 'Sankaku Corner' (the triangular mesh bin in the sink). Some people call the bin itself namagomi, but it is actually the container for it. You should say 'Namagomi o sankaku kōnā ni suteru' (Throw the kitchen waste into the triangular corner bin).

Finally, be careful with the pronunciation of 'Gomi.' It is a low-high-low pitch in some dialects, but generally flat in standard Japanese. If you emphasize the 'Go' too much, it might sound like the number five (Go). Keep it natural and integrated into the phrase.

To truly master the vocabulary of waste, you need to know how 生ゴミ compares to its synonyms and related terms. While namagomi is the king of the kitchen, other words provide specific nuances depending on the context of the food waste.

生ゴミ vs. 残飯 (Zanpan): Zanpan refers specifically to 'leftover food' that was served but not eaten. It has a slightly more negative connotation of wastefulness. Namagomi is a broader category that includes zanpan plus all the inedible parts like onion skins and bones.
生ゴミ vs. 燃えるゴミ (Moeru Gomi): In almost all Japanese cities, namagomi is a type of Moeru Gomi (combustible waste). When you look at a trash schedule, you might not see the word namagomi; instead, it will say 'Moeru Gomi,' and the fine print will explain that this includes food waste.
生ゴミ vs. 食品ロス (Shokuhin Rosu): Shokuhin Rosu (Food Loss) is a modern, academic, and social term. It refers to the systemic issue of edible food being thrown away. While namagomi is the physical stuff in your bin, shokuhin rosu is the societal problem being discussed in the news.

レストランの残飯は、家では生ゴミとして処理されます。(Restaurant leftovers are processed as kitchen waste at home.)

There is also the term Kitchin Gomi (Kitchen Trash), but this is less common and usually refers to the non-organic trash generated in the kitchen, like plastic wrap or empty bottles. Stick to namagomi for anything that used to be alive and on your plate. Understanding these distinctions helps you navigate conversations about housework and environmentalism with precision.

How Formal Is It?

Fun Fact

The word 'Gomi' is said to have come from 'Gomi' (塵), meaning 'dust'. In the past, people didn't have as much 'namagomi' because they used every bit of food or fed it to livestock.

How to Use It

frequency

Extremely frequent in daily domestic life.

Common Mistakes

Calling a plastic bottle 'namagomi'. → Peto-botoru (PET bottle).
Namagomi is only for organic, rotting food waste.
Forgetting to drain the water. → Mizukiri o suru.
Leaving water makes the bag heavy and smelly, which is considered bad manners.
Putting namagomi out on the wrong day. → Check the 'Gomi-karendā'.
Trash is only collected on specific days. Putting it out early is a social faux pas.
Using 'namagomi' for non-food biological waste like grass. → Kusa (grass) or 'moeru gomi'.
While organic, garden waste is often handled differently than kitchen waste.
Pronouncing it as 'na-MA-go-mi'. → na-ma-go-mi (flat).
Putting strong stress on the second syllable sounds unnatural.

Tips

Use Baking Soda

Sprinkling baking soda (juuso) in your namagomi bag can help neutralize acidic odors from rotting food scraps.

Freeze It!

Some people in Japan keep their namagomi in a bag in the freezer until collection day to prevent any smell or bugs in the kitchen.

Mizukiri is Key

The lighter the bag, the easier it is for you and the trash collectors. Always drain the liquid.

Yellow Nets

If you put your trash outside, always use the provided yellow net to cover it, or crows will make a mess.

Watch the Neighbors

If you aren't sure where the namagomi goes, watch where your neighbors put theirs on collection day.

Learn the Kanji

Recognizing 生 (raw) and ゴミ (trash) will help you read any trash schedule in Japan instantly.

Small Bags

Use small bags for namagomi and tie them tightly. Don't wait for a big bag to fill up, or it will smell.

Start a Compost

If you have a garden, look into 'bokashi' composting for your namagomi.

Special Bags

Check if your city requires 'shitei-bukuro' (designated bags). Using the wrong bag means your namagomi won't be collected.

Morning Only

Never put out namagomi the night before. Crows and cats will get into it. Put it out on the morning of collection.

Memorize It

Mnemonic

Think of 'Nama' as 'Nama-beer' (Raw/Draft beer). 'Gomi' sounds like 'Go-Me'. So, 'Raw-Go-Me' is what the food scraps say when they want to be thrown out!

Visual Association

Imagine a triangular mesh basket in a Japanese sink filled with green vegetable peels. That image is the essence of 'namagomi'.

Word Web

Kitchen Smell Trash Leftovers Japan Recycle Water Crows

Challenge

Go to your kitchen and identify three things that would be classified as 'namagomi' in Japan. Say 'Kore wa namagomi desu' for each one.

Word Origin

Derived from the combination of the Japanese word 'Nama' (生 - raw, fresh) and 'Gomi' (ゴミ - trash). 'Gomi' originally referred to dust or dirt and was written with various kanji like 塵 or 芥 before katakana became standard.

Original meaning: Raw or wet waste material from food preparation.

Japonic

Cultural Context

Be careful when discussing trash with neighbors; it is a sensitive topic that can lead to local disputes if rules aren't followed.

In the US or UK, 'kitchen waste' is often just 'trash' or 'rubbish'. We don't distinguish 'raw' waste as much unless we are composting.

Featured in many Japanese 'slice of life' anime where characters argue about whose turn it is to take out the namagomi. Mentioned in the 'Mottainai' environmental movement.

Frequently Asked Questions

Generally, no. Paper should go in the 'combustible' (moeru gomi) or 'recyclable paper' (koshi) bin. Namagomi is for organic food waste only. However, if a small piece of paper is stuck to food, it's usually okay in the combustible bin.

In most Japanese cities, yes. Because food waste can be burned, it is categorized as combustible. However, some cities have separate organic collection for composting.

Mizukiri means draining the water. Since namagomi is wet, you should squeeze the water out or let it drain in a mesh bag before putting it in the trash bag to reduce weight and smell.

Crows are very smart and look for food scraps inside the bags. They can see through clear or white bags, which is why some cities use yellow bags or nets to deter them.

Most older Japanese apartments do not have them, and some municipalities discourage or ban them because the sewage system isn't designed for it. Always check your building rules.

Cooking oil is NOT namagomi. You should solidify it with a powder (kata-meru-ten) or soak it into paper and put it in 'moeru gomi'.

You can say 'namagomibako' (生ゴミ箱) or simply 'gomibako'.

Yes, fish and chicken bones are considered namagomi/combustible waste in most areas.

It is a triangular-shaped mesh basket that sits in the corner of the kitchen sink to collect namagomi while you cook.

Usually twice a week in most Japanese cities, as part of the 'combustible waste' schedule.
