Japan's garbage sorting system separates household waste into five core categories: burnable waste （燃えるごみ）, non-burnable waste （不燃ごみ）, recyclable resources （資源ごみ）, bulky waste （粗大ごみ）, and hazardous waste （有害ごみ）. Collection days, designated bag requirements, and sub-categories vary by municipality across Japan's 1,741 cities and wards. Incorrect sorting results in uncollected garbage tagged with a rejection sticker.

The 5 Core Waste Categories in Japan
Every Japanese municipality uses a variation of these five categories. Sub-categories and exact sorting rules differ by location — use GomiMate to see the exact rules for your ward.
What goes in
- Food scraps and kitchen waste (生ごみ)
- Dirty or used paper that cannot be recycled
- Cloth, clothing, rubber, leather
- Small wooden pieces, chopsticks
- Disposable diapers (sealed in a bag)
- Plastic film (by ward — check locally)
This is the highest-volume category for most households. Bags must be semi-transparent designated bags in many municipalities. Items must be drained of excess moisture. Do not include recyclable clean paper.
What goes in
- Small metal items: pots, pans, cutlery, wire
- Glass: cups, plates, mirrors, light bulbs (non-fluorescent)
- Ceramics and porcelain
- Small appliances under 30cm (fans, clocks, irons)
- Lighters (fully emptied), umbrellas
- Hard plastics (in wards that do not recycle them)
Items should be under 30cm in any direction — larger items are bulky waste (粗大ごみ). Wrap sharp items such as broken glass or blades in newspaper and label them as 危険 (dangerous). Collected far less frequently than burnable waste.
What goes in
- PET bottles (remove cap and label, crush flat)
- Aluminum and steel cans (rinsed, crushed)
- Glass bottles — brown, white, and coloured (rinsed)
- Cardboard — flattened and tied with string
- Newspapers, magazines — bundled with string
- Plastic packaging with the ♻ プラ mark
- Milk cartons — rinsed, dried, cut open flat
Items must be clean and rinsed. Contaminated recyclables are rejected. Sub-categories often have separate collection days in the same municipality — e.g. cans on Tuesday, PET bottles on Thursday. Caps and labels from PET bottles typically go in non-burnable or plastic packaging waste.
What goes in
- Furniture: sofas, tables, bookshelves, chairs
- Bicycles and motorcycles (not motorised)
- Futons, mattresses, large bedding
- Appliances not covered by the Appliance Recycling Law
- Items generally larger than 30cm in any direction
Bulky waste requires advance reservation — call or register online with your ward office. You receive a 粗大ごみ処理券 (disposal sticker, ¥400–¥2,400 fee depending on item size). Affix the sticker to the item and set it out on your scheduled day. Note: the 4 major home appliances (ACs, TVs, refrigerators, washing machines) are governed by the 家電リサイクル法 and must be returned to a retailer or manufacturer — they are NOT collected as sodai gomi.
What goes in
- Dry-cell batteries (乾電池) — also accepted at convenience stores
- Fluorescent tubes (蛍光管) — wrap carefully
- Button batteries (ボタン電池) — electronics stores, or ward collection
- Spray cans (スプレー缶) — fully empty and pierce (or ward-specific day)
- Fire extinguishers — specialist disposal required
- Mercury thermometers and sphygmomanometers
Hazardous items cannot go in regular burnable or non-burnable waste due to fire, chemical, or toxicity hazards. Many of these items have convenient drop-off points: dry-cell batteries at convenience stores and post offices, ink cartridges at electronics retailers. Check your ward's specific collection day or nearest drop-off location. GomiMate's sort guide shows drop-off options by item.
Universal Collection Rules Across Japan
These rules apply in virtually every Japanese municipality, even where other details differ.
Morning of collection day only — before 8:00 AM
Put garbage out on the morning of the collection day, not the night before. Most municipalities prohibit leaving garbage out overnight as it attracts crows and disturbs neighbours. The standard cut-off is 8:00 AM, though some areas set earlier times. GomiMate's night-before reminder helps you prepare without putting bags out too early.
Use your designated collection point
Each residential block has a specific garbage collection spot (ゴミ集積所). You must use the collection point assigned to your address. Leaving garbage at an incorrect station will result in it being left uncollected. New residents can find their assigned collection point by asking their landlord, building manager, or ward office.
Rinse recyclables before putting them out
Contaminated recyclables — food residue in cans, drinks remaining in PET bottles — are classified as non-recyclable and will be rejected. Rinse containers briefly under water and allow to air-dry. This is one of the most common reasons garbage is left uncollected in Japan.
Use designated bags where required
Many municipalities require 指定ごみ袋 (designated garbage bags) bearing the ward or city name. These are available at convenience stores, supermarkets, and home centres typically for ¥100–¥300 per pack of 10. Using a non-designated or opaque bag where transparent bags are required can result in uncollected garbage.
Flatten and tie recyclable paper and cardboard
Cardboard boxes must be broken down flat and tied with string (紐) or an elastic band, not placed in a bag. Newspapers and magazines should be bundled by type. Loose cardboard stacked without binding may be left uncollected.
Why Garbage Rules Vary Between Japanese Cities
Under Japan's 廃棄物の処理及び清掃に関する法律 (Waste Management and Public Cleansing Law, enacted 1970), each of Japan's 1,741 municipalities is independently responsible for managing its own waste collection. The national government sets minimum standards and recycling targets, but municipalities determine their own categories, collection frequencies, bag requirements, and fees.
As a result, the same item can be classified differently across cities. A hard plastic cutting board is 不燃ごみ in Shibuya-ku, プラスチックごみ in Minato-ku (a recyclable), and 燃えるごみ in some other wards. Yokohama's system divides household waste into 10 categories, while some rural municipalities use just 3.
Nagoya became a landmark case in the early 2000s when a waste crisis — with only 3 years of landfill capacity remaining — spurred the city to implement one of Japan's strictest sorting regimes. The result was a dramatic reduction in general waste and significantly extended landfill life. Nagoya's model influenced waste policy across Japan.
Always verify rules for your specific municipality
This guide provides general principles that apply across Japan. Your ward's specific collection days, bag requirements, and sorting rules may differ. Use GomiMate or your ward office website for precise local rules.
Most Common Garbage Sorting Mistakes in Japan
These are the most frequent reasons garbage gets left uncollected with a rejection sticker.
Wrong day
Putting out burnable waste on a recyclables day, or vice versa. The single most common mistake, and the one GomiMate's calendar and reminders directly prevent.
Dirty recyclables
Placing unwashed food containers, cans with liquid, or oily plastic packaging in the recyclables bin. Always rinse before recycling.
PET bottle cap and label left on
Caps and labels must be removed from PET bottles before recycling. The bottle, cap, and label typically go in three different categories.
Putting appliances in non-burnable waste
Small appliances (fans, radios, hair dryers) are non-burnable waste, but the 4 major appliances (ACs, TVs, fridges, washing machines) require separate manufacturer/retailer recycling under the 家電リサイクル法.
Using the wrong collection point
Each address has an assigned collection spot. Using a neighbouring block's station is not permitted and may result in uncollected garbage or complaints from residents.
Mixing batteries with regular garbage
Dry-cell batteries and button batteries must be separated as hazardous waste (有害ごみ) or taken to designated drop-off points, not placed in burnable or non-burnable bags.
Sodai gomi without a sticker
Leaving bulky items without the advance-reservation sticker (粗大ごみ処理券) will result in them being left uncollected indefinitely. Reservation and fee payment are mandatory.
Frequently Asked Questions
What does 燃えるごみ (moeru gomi) mean?
燃えるごみ literally means 'burnable waste' in Japanese. It covers food scraps, dirty paper, cloth, rubber, leather, small wood pieces, disposable diapers, and plastic film (in many wards). It is typically collected twice a week and is the highest-volume waste category for most Japanese households. It is processed at waste-to-energy incineration facilities.
What is the difference between 不燃ごみ and 資源ごみ?
不燃ごみ (funen gomi) is non-burnable waste with no recycling value — small metal items, ceramics, glass cups, small appliances, and lighters. 資源ごみ (shigen gomi) is recyclable material with reuse value — PET bottles, cans, glass bottles, cardboard, and newspapers. Non-burnables go to landfill or special processing; recyclables are sorted and reprocessed into new materials. Never mix the two: a contaminated recyclable stream is treated as non-burnable waste.
What is 粗大ごみ and how do I dispose of it?
粗大ごみ (sodai gomi) is bulky waste — items larger than approximately 30cm in any direction. Examples include furniture, bicycles, and futons. You must reserve a collection day in advance via your ward office (by phone or online), pay a fee of typically ¥400–¥2,400, receive a disposal sticker (粗大ごみ処理券), affix it to the item, and set it out on the scheduled morning. Note: the four major home appliances (ACs, TVs, refrigerators, washing machines) require retailer/manufacturer recycling under the 家電リサイクル法 and cannot be disposed of as sodai gomi.
Do I need to buy special garbage bags in Japan?
It depends on your municipality. Many cities and wards require 指定ごみ袋 (designated bags) printed with the ward or city name, sold at convenience stores and supermarkets for roughly ¥100–¥300 per pack of 10. Some Tokyo wards (including several central wards) do not require designated bags. Check your specific municipality's rules — using a non-designated bag where one is required will result in uncollected garbage.
What time should I put out garbage in Japan?
In most municipalities, garbage must be put out on the morning of the collection day before 8:00 AM. Putting bags out the night before is prohibited in most areas and considered antisocial, as it attracts crows and other animals. Some enclosed collection stations in apartment buildings may allow earlier placement. GomiMate sends you a night-before reminder so you can prepare your bags without putting them out too early.
Why are garbage rules different in every Japanese city?
Japan's 1,741 municipalities each manage their own waste independently under the 1970 廃棄物の処理及び清掃に関する法律. Each ward or city sets its own collection days, categories, bag requirements, and processing contracts. The same item can be classified differently across wards — a hard plastic container might be non-burnable in one ward and recyclable plastic in the next. This local complexity is exactly why GomiMate exists.
How do I find my garbage collection schedule in Japan?
Three options: (1) Request access to the GomiMate beta at gomimate.com — once approved, select your ward and the app imports your official collection calendar automatically. (2) Visit your ward or city office website (区役所/市役所) for a downloadable PDF calendar. (3) Look for the collection schedule slip (ゴミ収集票) posted at your nearest garbage collection point, which GomiMate can also scan and import with your camera.
What happens if I sort garbage incorrectly in Japan?
Collection workers leave incorrectly sorted garbage uncollected and attach a rejection sticker (収集不可) explaining the problem — for example 'wrong day', 'mixed waste types', or 'wrong bag'. You must take the bag back and correct it for the next appropriate collection day. Repeated violations can result in a written warning from your ward office. GomiMate's calendar, reminders, and sort guide are designed to prevent this entirely.
