Should PET bottle caps be removed and sorted separately from the bottle?

Yes — Yes — the bottle, the cap, and the label all go in different categories. The cap and label typically count as plastic packaging, while the bottle itself is PET — though some municipalities classify caps as burnable, so check your local guide if you're staying long-term.

Is it okay to put all your garbage in one bag in Japan?

No — No. Burnable, non-burnable, PET bottles, cans, glass, and plastic packaging each have separate bags and separate collection days. Mixed bags often get rejected and left at the collection point.

Are garbage collection days the same for all types of garbage in Japan?

No — No — each category has its own day, and the schedule is set by your local municipality. Burnables might be twice a week, PET bottles once a week, non-burnables every other week, and so on.

Japan Garbage Sorting Rules: Burnable vs Non-Burnable

Burnable, non-burnable, PET, plastic packaging, cans, glass — each has its own collection day. Tourists in apartments get this wrong constantly.

One-bag-fits-all

Dumping everything into a single bag

In Japan you genuinely cannot just stuff all your trash into one bag and call it a day. Burnable and non-burnable have to go in separate bags (often specific colors), and PET bottles, cans, glass, and plastic packaging are each their own category. Mix them and your bag may be left uncollected — sometimes literally slapped with a warning sticker and returned to where it came from.

Sort as you go, one small bin per category

The easiest trick is to set up a few small bags from day one — one for burnables (food scraps, tissues, most paper), one for PET bottles, one for cans and glass, and one for plastic packaging. It feels fiddly for about a day, then it becomes automatic. If you're not sure which pile something belongs in, a quick search for your city name plus 'gomi guide' almost always turns up a chart.

Wrong-day drop-off

Putting bags out on the wrong collection day

Each category has its own pickup day — burnables might be Monday and Thursday, PET bottles only Tuesday, non-burnables every other Friday, and so on. Drop a bag at the collection point on the wrong day and it just sits there for days, attracting crows and very unhappy neighbors. In residential Japan this is taken extremely seriously — there are even neighborhood associations that track it.

Your rental host, landlord, or city website will have a collection calendar showing which category goes out on which day. Put bags out the morning of collection, not the night before — this keeps crows and animals away and is the local norm. If you're leaving before the next pickup, ask your host what to do; most short-stay places have a solution for leftover trash.

Unrinsed recyclables

Tossing sticky bottles and cans straight into recycling

A half-finished cola bottle with the label still on, cap still screwed down, tossed in with the PET bottles? That's three sorting mistakes in one. PET bottles and cans need to be empty and rinsed, the plastic label peeled off (it goes with plastic packaging), and the cap removed and sorted separately. Sticky, dirty recyclables can get the whole bag rejected.

Rinse, peel, separate — then recycle

Finish the drink, give the bottle a quick rinse under the tap, peel the plastic label off (you'll see a little perforation line to help), unscrew the cap, and you now have three items in three different bins: the bottle, the cap, and the label. It sounds like a lot, but it takes about ten seconds and it's the single biggest thing that separates 'proper' sorting from a rejected bag.

Konbini bin abuse

Dumping your apartment trash at a convenience store bin

Konbini garbage bins are meant strictly for things you bought at that konbini — an empty coffee cup, an onigiri wrapper, a water bottle. Hauling a bag of apartment or hotel trash over and stuffing it in is a pretty common tourist shortcut, and it's specifically not allowed. Many stores now have signs (in several languages) explicitly banning it, and staff will absolutely call it out.

Deal with rental trash through your rental

If you're staying in an Airbnb or weekly mansion, the host's house rules will tell you exactly where and when to take the trash — follow that, not the konbini shortcut. For a konbini bin, stick to whatever small wrapper or bottle you just bought there. And for hotel guests, you don't need to worry about any of this at all; the hotel handles sorting on your behalf.

Why Japan’s garbage system is like this

If you’ve only ever dealt with Japanese trash through a hotel room bin, it’s easy to miss just how intense the system really is. But the moment you step into an Airbnb, a weekly mansion, or a friend’s apartment, the full thing comes into view: several bins in the kitchen, a laminated calendar on the fridge, color-coded bags under the sink, and a set of rules that feel almost comically specific.

There’s a reason for all of it. Japan is a small, densely populated country with very limited land for landfill, so from early on the national strategy was to incinerate burnable waste and aggressively recycle everything else. That means the whole system is built around sorting at the source — every household becomes the first step in the recycling chain. A major environmental push in the 1990s locked in today’s strict categories, and they’ve only gotten more detailed since.

For residents, sorting isn’t just a suggestion from city hall — it’s a social norm enforced by neighbors. Bags are left at a shared collection point, in the open, where everyone can see whose trash is whose. A bag with the wrong contents, or left out on the wrong day, gets a bright red or yellow sticker and is left behind as a very public “please redo this.”

As a tourist, nobody expects you to memorize every rule on your first day. But if you’re self-catering, the expectation is that you try — and that you check the guide your host gave you rather than winging it.

Short version: sort into burnable, non-burnable, PET bottles, cans, glass, and plastic packaging; rinse recyclables; put each category out only on its designated day; and never dump rental trash in a konbini bin.

A few “nice to know” extras

Hotels handle it for you — If you’re staying in a normal hotel or ryokan, sorting is entirely the staff’s problem. You can toss things in the room bin and forget about it. This whole article is really aimed at Airbnb, weekly mansion, and long-stay guests.
Free multilingual garbage guides — Almost every municipality publishes a sorting guide, and most major cities now have English, Chinese, and Korean versions as free PDFs on the city website. Search “[your city] gomi guide English” and you’ll usually find it in seconds.
Designated bags — Some cities require you to buy specific colored or labeled garbage bags from the supermarket (often called shitei gomi bukuro). Using a random bag from home won’t work in those cities — it’ll be left behind.
Almost no public trash cans — You’ll notice Japan has very few street garbage bins, which is a whole separate quirk (we cover it in the no-trash-cans article). The short version: carry your rubbish with you until you get home.
The red sticker of shame — If your bag is sorted wrong or put out on the wrong day, collectors slap a bright warning sticker on it and leave it at the collection point. It’s not a fine, but it is embarrassing — and it’s how neighbors figure out who the new foreign resident is very quickly.
