"What kind of garbage day is today?"

After moving to Japan, garbage rules are one of the most confusing parts of daily life. Days, sorting categories, bag types, drop-off times — there's a lot to learn, and mistakes can hurt your relationship with neighbors.

But the basics are manageable. This guide covers Japan's four main garbage categories, the day-and-time rules, special items like PET bottles and oversized waste, and what happens when you get it wrong.

Why is Japanese garbage sorting so complicated?

People are often surprised at how detailed the sorting is. There are two main reasons:

  1. Resource recovery — to recycle paper, glass, cans, PET bottles, and more
  2. Protecting processing facilities — non-burnable items can damage incinerators, and lithium batteries cause fires

Japan is a small country with limited landfill space. The system is designed to prioritize "returning materials as resources" over "throwing away."

The most important rule: every city does it differently

This is the single most important thing to know. There is no national garbage rule in Japan. Sorting rules differ entirely by city / ward (jichitai).

  • Some cities collect PET bottles as a "resource"; others lump them in with plastics
  • Some require clear bags; others require paid bags sold by the city
  • Burnable garbage might be collected twice a week in one neighborhood, three times in another

The first thing to do after moving in is get your city's garbage sorting calendar.

Where to get it

  • Ward office: Distributed at the counter when you file your move-in notice
  • Official website: Search "[city name] gomi bunbetsu"
  • Apps: "San-A-Ru" (さんあ〜る) and "Gomi-Suke" (ごみスケ) are official apps used by many cities, with date-based notifications
  • Multilingual versions: Many cities offer guides in English, Chinese, Vietnamese, and other languages

The four main categories

Detailed rules vary by city, but the broad strokes are the same everywhere.

1. Burnable garbage (moeru gomi / kanen gomi)

  • What it includes: food waste, paper scraps, disposable chopsticks, cloth, leather goods, small wood scraps
  • Frequency: Usually 2–3 times per week
  • Bags: Some cities require paid official bags; others accept any clear or semi-transparent bag

For food waste, drain off the water before bagging. Wet waste is heavy and causes odor.

2. Non-burnable garbage (moenai gomi / funen gomi)

  • What it includes: ceramics, glass, metal, umbrellas, fluorescent bulbs, dry-cell batteries, small appliances
  • Frequency: Usually only 1–2 times per month
  • Notes: Wrap fluorescent bulbs in their original box or in newspaper to prevent breakage. Some cities require dry-cell batteries to be placed in a separate collection box.

Critical: lithium-ion batteries Lithium-ion batteries inside mobile chargers, laptops, e-cigarettes, and wireless earbuds must never be mixed in with regular trash. Fires from these have been rising nationwide. Take them to designated drop-off boxes at electronics retailers or your city office.

3. Recyclable resources (shigen gomi)

  • PET bottles
  • Cans (aluminum, steel)
  • Glass bottles (clear, brown, others)
  • Newspapers, magazines, cardboard, paper cartons
  • Plastic packaging (food trays, snack wrappers, etc.)

In many areas, these have separate collection days by type.

4. Oversized waste (sodai gomi)

Furniture, bicycles, futons, and other large items (typically anything over 30cm on one side) excluding the four major appliances. We'll cover this in detail below.

Items that don't fit the four categories

  • Home Appliance Recycling Law items: Air conditioners, TVs, refrigerators / freezers, washing machines / clothes dryers (the "big four"). These cannot go out as oversized waste — you pay the original retailer or any major appliance store to take them.
  • PCs: Manufacturers or designated collection services (under the Resources Effective Utilization Promotion Act)
  • Motorcycles: The two-wheel recycling system
  • Medications and needles: Take them back to the pharmacy or hospital that issued them
  • Fire extinguishers and gas cylinders: The retailer or a specialty disposal company

How to dispose of PET bottles correctly

A PET bottle is made from three different materials.

Part Material Where it goes (in most cities)
Body (with the PET mark) PET (polyethylene terephthalate) Recyclables (PET bottle)
Cap PP (polypropylene) Plastic packaging
Label PP, PS, PE, etc. Plastic packaging

Step by step

  1. Remove the cap
  2. Peel off the label (most have a perforated tear line)
  3. Rinse the inside briefly with water
  4. Crush the bottle to save space
  5. Put it out on resource collection day

Why separate them? The PET body is melted down into fiber or new bottles. The purer the material, the better the recycled output — which is why mixing in the cap and label (made of different plastics) hurts recycling quality.

If a label genuinely won't come off, some cities accept "as-is." Check your local rule.

How to throw out oversized waste — booking and stickers

Oversized waste won't be picked up if you put it out on a regular garbage day. In most cities, the process looks like this:

1. Make a reservation

  • Call or apply online to your city's "Oversized Waste Reception Center"
  • Tell them the item and size; they'll quote a fee, pickup date, and location
  • During busy seasons (year-end, March–April moving season), pickups can be a month or more out

2. Buy "oversized waste disposal stickers"

  • Sold at convenience stores, ward offices, and select supermarket counters (¥200 to a few thousand yen)
  • Buy stickers totaling the quoted fee, write your reservation number or name, and stick them on the item

3. Put it out on the assigned morning

  • By the morning of the assigned day (usually before 8:30), place it in the designated spot (often in front of your building)
  • You don't need to be present — the collection crew picks it up

Rough fee guide (varies by city)

Item Approximate fee
Futon / carpet ¥300–500
Chair / electric fan ¥300–500
Bicycle ¥500–1,000
Single bed ¥1,000–2,000
2-seater sofa ¥1,500–2,500

Beware of "free pickup" services. Using unlicensed operators can make you complicit in illegal dumping, and there are repeated cases of people being charged exorbitant fees after the items are loaded onto the truck.

Time and location rules

Time

  • Morning rule: Most cities require trash to be out by 8:00 or 8:30 a.m.
  • Don't put it out the night before: Crows and cats will tear it open

Location

  • Apartment buildings: the on-site garbage area
  • Detached houses: a neighborhood collection point set by the local residents' association (often on a corner or beside a utility pole)

Joining the residents' association is voluntary, but you may still be assigned cleanup duty for the collection area on a rotating basis. Ask your landlord or neighbors.

What happens if you get it wrong?

Improperly sorted garbage is usually left behind. In most cases, a warning sticker explains why.

  • First time: a sticker is left and the trash is not collected
  • Repeat offenses: the residents' association or property management may give you a warning
  • Severe cases: people who let trash pile up to the point of harming neighbors have been prosecuted under the Waste Management Act

The bigger issue isn't the violation itself — it's the damage to neighborhood relationships. Garbage disputes consistently rank among the top neighbor complaints in Japanese apartment buildings.

FAQ

Q. I can't read the garbage calendar in Japanese.

A. Many cities provide multilingual versions. Ask at the ward office for a "[your language] garbage calendar." The "San-A-Ru" app supports many languages depending on the city, and Google Translate can read paper calendars through your camera.

Q. What about the massive trash from moving out?

A. Furniture and appliances often can't be reserved for oversized pickup quickly enough — plan a month ahead. Your options:

  • City oversized waste pickup (cheap, slow)
  • Licensed private hauler (fast, expensive)
  • Sell to a recycle shop or give away on Jimoty
  • Your moving company's "unwanted item disposal" option

Q. How do I throw away cardboard?

A. Fold it flat and tie it crosswise with twine (paper twine recommended), then put it out on resource collection day. Most cities don't require you to remove tape or address labels. On rainy days, cardboard becomes harder to recycle, so just keep it indoors until the next collection.

Q. How do I dispose of cooking oil?

A. Don't pour it down the sink (it clogs pipes and pollutes water).

  • Soak it up with newspaper or paper towels and put it in burnable garbage
  • Use a commercial oil solidifier and discard as burnable
  • Drop it at supermarket or city collection boxes (recycled into biofuel)

Q. How do I throw away needles and medication?

A. Never put needles in regular garbage — collection workers can be injured. Take them back to the pharmacy or hospital that issued them. Most pharmacies will also collect unused medication (ask the pharmacist).

Q. What about anything containing a lithium-ion battery?

A. Major electronics retailers (Yodobashi, Bic Camera, Edion) have collection boxes. Removable batteries can be dropped at any "JBRC" partner store for free. More cities are also setting up dedicated collection points.

Q. What do I do with a deceased pet?

A. The three common options: bury on private property (deep), request your city's animal disposal service (paid, communal), or use a private pet cemetery / cremation service. Never put a pet in household garbage.

Q. Where do I buy the city-issued bags?

A. In areas that require them, almost every nearby supermarket, convenience store, and drugstore sells them. Look for a "designated bag retailer" (shitei-bukuro toriatsukai-ten) sticker on the storefront.

Final thoughts

Garbage in Japan isn't about memorizing a giant rulebook — it's mostly about taping one calendar to your fridge and following it.

Three things you can do today:

  1. Download the sorting calendar from your city's official website
  2. Install your city's official garbage app (like San-A-Ru) and turn on notifications
  3. Set up at least four bins at home: burnable / plastics / PET bottles / cans & glass

Just doing these will let you live in peace, without your neighbors getting upset.

At Nihongo-tomo, we offer free vocabulary lists for garbage, recycling, and ward office terms. Learning the kanji for "burnable" (可燃), "non-burnable" (不燃), and "oversized" (粗大) ahead of time makes weekly garbage day far easier.
