Moving to Japan is exciting, but garbage day can feel confusing at first. Different bags, different days, different rules for every city — it is a lot to remember. Don't worry, we'll make it simple. This guide uses plain English and emoji so you can sort your garbage correctly from day one.

日本のゴミ出しルールは、種類が多くて最初は戸惑う方が多いです。この記事では、英語と日本語を併記しながら、絵文字を使ってわかりやすく解説します。日本での新生活を安心してスタートできるよう、基本から丁寧にご案内します。

Why Japan Has 4-7 Garbage Categories

Japan sorts garbage into more categories than many other countries — usually between 4 and 7, depending on the city. This is not random. It comes from national recycling policy: Japan has very limited landfill space, so recycling as much as possible is a priority. Sorting garbage correctly helps turn cans, bottles, and paper back into new products instead of burying them.

Each city (called a jichitai, or local municipality) sets its own detailed rules on top of this national policy. That is why the categories can look different when you move from one city to another.

日本でゴミの分類が多い理由は、国土が狭く埋め立て地が限られているためです。資源を再利用するリサイクル政策が背景にあります。分類ルールは自治体（市区町村）ごとに細かく異なるため、引っ越すたびに確認が必要です。

Basic Categories with Emoji

Here is the simplest way to remember the main categories. Use this chart as your quick reference.

Most cities collect burnable garbage 2 times a week, recyclables and cans/bottles once a week, and bulky waste only by advance reservation.

多くの自治体では、燃えるゴミは週2回、資源ゴミ・缶びんは週1回の収集が一般的です。粗大ゴミは事前予約制で、決まった日にしか出せません。

Plastic — The Most Confusing Part

Plastic is where almost every foreign resident gets confused, so let's slow down here.

In Japan, plastic packaging with the プラ (pura) mark — a small triangle symbol printed on the package — usually goes into recyclable plastic, not burnable garbage. This includes things like snack wrappers, plastic trays, and shampoo bottle caps. However, plastic products (like a plastic toy, a bucket, or a hanger) are often treated as burnable or non-burnable garbage depending on the city, because they are not "packaging."

The other confusing point is dirty plastic. If a plastic container is heavily soiled with food (for example, a curry container that won't rinse clean), most cities ask you to put it in burnable garbage instead of recyclable plastic, because contamination can ruin an entire batch of recycling.

プラスチックの分別は、外国人の方が最も混乱しやすいポイントです。「プラマーク」がある容器包装は資源ゴミ、洗っても汚れが落ちない容器は燃えるゴミへ、という基本ルールを覚えておくと安心です。迷った場合は自治体公式サイトの分別表をご確認ください。

Bag Color & Designated Bags by City

Some cities require you to buy special "designated bags" (指定袋) sold at supermarkets and convenience stores. Others allow any transparent or semi-transparent bag. Here is a quick comparison of 5 major cities as of June 2026.

5都市のうち名古屋市のみ指定袋の購入が必要です。他の4都市は透明・半透明の袋であれば市販のもので構いません。不透明な黒い袋は収集してもらえないことが多いのでご注意ください。詳細は必ずお住まいの自治体公式サイトでご確認ください。

Collection Day — How to Find Yours

Your garbage collection day depends on your exact address, not just your city. Here is how to find it:

1. Check your city's official website — most large cities now have an English-language page, though smaller towns may not.
2. Look for a printed calendar — when you register your address at the ward office (区役所/市役所), you are often given a paper garbage calendar.
3. Ask your landlord or real estate agent — they usually know the local rules and can point you to the right resource.
4. Use Gomi-Q — this site helps you search your area's collection days and sorting rules in one place.

収集日はお住まいの住所によって異なります。自治体公式サイトの検索や、区役所・市役所で配布されるカレンダー、不動産会社への確認がおすすめです。ゴミQでもお住まいの地域の収集日を検索できます。

Sodai-gomi (Bulky Waste) — What to Do

Large items like furniture, mattresses, and bicycles cannot be put out with regular garbage. They require a special process called sodai-gomi (粗大ゴミ).

1. Apply online or by phone to your city's sodai-gomi reception center, and tell them the item and its size.
2. Buy a sticker (処理券) at a nearby convenience store or supermarket — the price depends on the item.
3. Attach the sticker and put the item out on your scheduled collection day, usually in front of your building before 8am.

This process usually takes 1-2 weeks from application to collection, so plan ahead if you are moving out.

粗大ゴミは通常のゴミと違い、事前申込みと処理券の購入が必要です。申込みから収集まで1〜2週間ほどかかることが多いため、引っ越し前は早めの手続きをおすすめします。

Common Mistakes Foreign Residents Make

Here are the 10 most common mistakes — learning these now will save you a lot of confusion later.

1. Throwing plastic packaging into burnable garbage — Look for the プラ mark first. プラマーク付きの容器包装をそのまま燃えるゴミへ出してしまう。
2. Not rinsing containers — Dirty cans, bottles, and plastic trays can be rejected. 容器を洗わずに出してしまう。
3. Missing the collection time — Most areas require garbage out by 8:00-8:30am, not the night before. 朝8時頃までのルールを知らずに前夜に出してしまう。
4. Putting garbage out on the wrong day — Each category has its own fixed day of the week. 曜日ごとに分類が違うことを知らずに出してしまう。
5. Not folding or tying cardboard — Loose cardboard boxes are often refused; tie them with string. 段ボールを紐で縛らずに出してしまう。
6. Batteries in burnable garbage — This is a real fire risk in collection trucks; batteries need separate hazardous disposal. 電池を燃えるゴミに混ぜてしまい、収集車の火災事故につながることがある。
7. Using an opaque or black bag — Many cities reject bags where contents can't be seen. 中身が見えない黒い袋を使ってしまう。
8. Putting out sodai-gomi without a sticker — Furniture and appliances left without the paid sticker will not be collected. 処理券を貼らずに粗大ゴミを出してしまう。
9. Assuming all cities have the same rules — Moving to a new city means checking the rules again from scratch. 前の街のルールがそのまま通用すると思い込んでしまう。
10. Ignoring size limits — Some "non-burnable" categories have size limits before an item becomes sodai-gomi. サイズ制限を知らず、粗大ゴミ扱いのものを普通ゴミとして出してしまう。

外国人の方によくある失敗を10個まとめました。特に「プラの分別」「収集時間」「電池の混入」は要注意ポイントです。最初にこのリストを確認しておくだけで、多くのトラブルを防ぐことができます。
