Rubbish sorting

What the categories actually are

There is no single national rule. Waste management in Japan is governed by the 廃棄物処理法（はいきぶつしょりほう, Waste Management and Public Cleansing Act）, but the concrete sorting categories are set by each 自治体（じちたい, municipality）—city, town, or ward. Two neighbouring wards in Tokyo can have different rules.

Most municipalities use some version of these:

• 燃えるゴミ（もえるゴミ, burnable rubbish）: food scraps, paper that is not recyclable, dirty plastic, rubber, leather, small wooden items.
• 燃えないゴミ（もえないゴミ, non-burnable rubbish）: metal, ceramics, glass that is not a bottle, small appliances, light bulbs.
• 資源ゴミ（しげんゴミ, recyclable resources）: often subdivided into プラ（プラスチック, plastic packaging）, ペットボトル（PET bottles）, ビン（glass bottles）, カン（cans）, 紙（かみ, paper）, and 布（ぬの, cloth）.
• 粗大ゴミ（そだいゴミ, oversized rubbish）: furniture, bicycles, large appliances. These require a paid sticker or a booking, and are not put out with normal collection.
• 有害ゴミ（ゆうがいゴミ, hazardous waste）: batteries, fluorescent tubes, syringes, sometimes spray cans.

Some cities go further. Yokohama uses ten categories; Kamikatsu in Tokushima is known for around forty-five. The number is a local political decision, not a national standard.

Why it is so detailed

Three pressures explain the granularity.

First, land. Japan is mountainous, and suitable landfill sites are scarce and politically difficult to build. Incineration reduces volume sharply, so the system is built around what can be burned safely. Plastics that release toxic gases, batteries that can ignite in a collection truck, and aerosol cans that explode under heat all have to be kept out of the burnable stream.

Second, the recycling laws. The 容器包装リサイクル法（ようきほうそうリサイクルほう, Containers and Packaging Recycling Act）of 1995 made manufacturers and municipalities share the cost of recycling packaging. The 家電リサイクル法（かでんリサイクルほう, Home Appliance Recycling Act）of 1998 covers televisions, refrigerators, washing machines, and air conditioners. These laws created the separate streams that households now have to feed.

Third, collection logistics. A truck that picks up mixed waste has to pay to sort it later, or the whole load may be rejected at the processing facility. Clean separation at the household is cheaper than separation at the plant.

How the rules reach you

Every household receives a ゴミ分別表（ゴミぶんべつひょう, sorting chart）, usually a colour-coded calendar showing which category is collected on which weekday and which weeks. Many wards publish it in English, Chinese, Korean, and Portuguese as well. Buildings often post the chart near the collection point.

The chart is the authority. If you are unsure whether a item is プラ or 燃えるゴミ, the chart usually has an index by item name.

What happens if you get it wrong

In most cases, nothing dramatic. The collection crew will leave the bag at the collection point with a red or yellow sticker explaining the problem. You are expected to take it home, fix it, and put it out on the correct day. This is the normal outcome, and it is not a legal matter.

If a bag is left repeatedly, or if the contents are dangerous, the municipality can escalate. Under local ordinances, some cities impose a fine—commonly in the range of a few thousand yen—for persistent illegal dumping (不法投棄, ふほうとうき). Deliberate dumping of household waste in a public place, or of appliances without the recycling fee, is a more serious matter and can be prosecuted under the Waste Management Act.

Social pressure does most of the work. In apartment buildings, a mis-sorted bag inconveniences neighbours and is visible to them. The 町内会（ちょうないかい, neighbourhood association）and building managers often remind residents directly.

Practical notes for residents and visitors

• Visitors in hotels and rentals are usually covered by the building's own sorting; ask the host or front desk.
• PET bottles: remove the cap and label if your municipality asks; some accept them attached, some do not.
• Spray cans: empty them fully outdoors before disposal, and follow the local rule—often 燃えないゴミ or a separate hazardous day.
• Batteries: almost never in the normal stream. Shops often have collection boxes.
• Oversized items: buy the 処理券（しょりけん, processing sticker）at a convenience store, attach it, and book collection.

Learning the vocabulary around this is useful. Terms like 分別（ぶんべつ, separation）, 収集日（しゅうしゅうび, collection day）, and 資源（しげん, resources）appear constantly on signs and in notices. A dictionary helps, and the vocabulary section covers everyday words of this kind.
