A Japanese garbage calendar is a reading task with a real decision at the end. You may know that ペットボトル means plastic bottle, yet still need to find the correct collection day, remove the right parts, and identify where to leave it. A translation of one noun will not answer all three questions.
This guide is for learners reading a neighborhood notice, apartment handout, or municipal PDF. It teaches you to extract category, day, preparation, and place from the Japanese before acting. The examples are invented language exercises. Collection rules differ by municipality and sometimes by neighborhood, so use your current local notice or city guide for an actual disposal decision. The Japan Foundation's IRODORI lesson on garbage sorting teaches the same practical reading task: understand when and how to put out an item.
Find the authority and address first
Before reading the colorful category chart, identify who issued it. Look for a city, ward, building manager, or neighborhood association. Then find a publication date or revision label, and confirm that the notice applies to your address. An old poster from another ward can teach vocabulary without telling you what to do at your own collection point.
The Japan Foundation explains that broad labels such as burnable, non-burnable, recyclable, and oversized waste recur, while the details vary by area. Compare the current Yokohama Japanese sorting guide with Shinjuku's resident-facing guide: both are official local resources, but neither is a nationwide schedule.
Write the issuer and your collection location at the top of your notes. If you live in an apartment, check whether the building gives separate instructions for its collection room or pickup point. Keep that building notice beside the municipal page. If the two seem inconsistent, ask the manager or the local collection office rather than guessing which sheet wins.
Read the category words as headings
分別（ぶんべつ） means sorting or separation. 資源（しげん） refers to resources that can be collected for recycling in this context. Find the heading that names the stream before deciding where an object belongs:
- 燃えるごみ / 燃やすごみ / 可燃ごみ: labels for burnable waste.
- 燃えないごみ / 燃やさないごみ / 不燃ごみ: labels for non-burnable waste.
- 資源ごみ / 資源物: recyclable resources, often divided further.
- 粗大ごみ（そだいごみ）: oversized waste, which usually has its own instructions.
The IRODORI cultural note presents these broad categories and warns that the contents of each can vary locally. Learn the alternate labels so you can recognize the heading on a different notice; do not turn that list into a universal item-to-bin rule. In one city, a particular plastic item may be handled differently from how a familiar English word like “recyclable” leads you to expect.
For an unfamiliar object, copy the exact item name and category from the responsible guide. 品目（ひんもく） means item or article in a sorting list. A city's item lookup may be more useful than translating the material by eye. If the guide names exceptions, keep them with the item rather than memorizing only the broad heading.
Separate packaging marks from collection instructions
A package may carry a プラ, 紙, or PET identification mark. Those marks help you recognize what a piece of packaging is. They do not, by themselves, give your address's collection day or tell you how to prepare it. Japan's Ministry of Economy, Trade and Industry explains the scope of identification marks for containers and packaging, including why different parts of one package can carry different marks.
Imagine an invented bottle label that identifies ボトル：PET、キャップ：プラ、ラベル：プラ. Read the component nouns first: bottle, cap, and label. Then read the mark next to each. This is a material-identification exercise, not an instruction to place all three pieces together or apart in a particular city. Look up your local category and preparation rules afterward.
Watch for 容器包装（ようきほうそう）, containers and packaging, versus 製品（せいひん）, the product itself. A plastic wrapper and a plastic household item need not follow the same local route. If a flyer says 対象（たいしょう）, it is defining which items are covered. If it says 対象外（たいしょうがい）, that item is excluded from the rule beside it. The final 外 can reverse a quick guess based on the familiar word 対象.
Decode the day and time without borrowing another district's schedule
Find 収集日（しゅうしゅうび）, collection day, or 収集曜日（しゅうしゅうようび）, collection weekday. Then read the category and its day on the same row. A calendar might distinguish 毎週 (every week) from 第2・第4 (second and fourth occurrences of a weekday). These patterns are easy to confuse if you copy only 木曜日.
Use this invented practice line: 資源物：毎週火曜日、朝8時までに集積所へ出してください。 It says to put the recyclables at the collection point by 8 a.m. every Tuesday *in the exercise*. までに means “by” a deadline; 集積所（しゅうせきじょ） is a collection point; 出してください asks you to put the items out. None of those details establishes your real Tuesday or time.
Yokohama's English resident guidance explicitly tells residents to check the sticker at their collection site or ask locally because days depend on where they live. Shinjuku provides an address-organized collection-day page. Those examples show the question to ask of your own municipality: “Which schedule applies to this address?” They are not interchangeable calendars.
Also read the prohibitions surrounding a time. 前日の夜 means the previous evening; 出さないでください means please do not put it out. If a notice pairs those phrases, the night before is excluded even when you know the collection day. Seasonal or holiday notices can change an ordinary schedule, so check the issue date of a special notice before applying it.
Turn preparation verbs into a sequence
After finding the right category and day, look for verbs that describe what to do to the item. The IRODORI lesson uses bottle caps, labels, and cardboard to practice exactly this kind of instruction. Its Elementary 2 word list groups sorting vocabulary with everyday verbs, which is useful when a notice uses a short command rather than a full explanatory sentence.
- 中身を空にする: empty the contents.
- 軽くすすぐ: rinse lightly.
- キャップを外す / ラベルを外す: remove the cap or label.
- つぶす: flatten or crush, depending on the item.
- ひもでしばる: tie with string.
- 分けて出す: separate and put out.
Read the object and verb together. ラベルを外す concerns the label; ボトルをつぶす concerns the bottle. A sentence with several て-forms can give an order: キャップを外して、軽くすすいで、出してください means remove the cap, rinse lightly, then put the item out. The sentence tells you the order, while the local guide tells you whether those steps apply to that item.
Notice qualifiers. 軽く changes “rinse” to “rinse lightly.” 汚れが落ちない場合 introduces a condition: if the dirt does not come off. Do not discard the rest of that sentence; the condition may redirect the item to a different category. When a picture and a sentence appear together, use the picture to identify the part and the sentence to capture the action.
Recognize exceptions and special disposal
Some items do not fit an ordinary weekly row. 粗大ごみ signals a separate oversized-waste process; 電池（でんち） means battery; スプレー缶 means aerosol can. Learn these as prompts to open the relevant local instructions, not as permission to use a generic bin. The Yokohama guide's contents separate oversized waste, batteries, and spray cans from its ordinary category pages.
Look for 申込み（もうしこみ）, an application or booking, 受付（うけつけ）, reception or acceptance, 手数料（てすうりょう）, a fee, and 指定場所（していばしょ）, a designated place. They are different fields. A list of acceptable items does not mean a pickup has been booked, and a booking screen does not tell you where to leave the item until it confirms a place. Yokohama's oversized-waste page is one official example of how collection details are supplied through a separate process.
If the item is broken glass, a battery, an appliance, or anything whose handling could affect another person, stop at the local source. Keep the Japanese item name visible when you ask the collection office a question. A plausible dictionary gloss is not enough to decide a safety-sensitive exception.
Practice on one notice in four passes
Choose a current notice for your own address, or use the Japan Foundation's sample strictly for study. Keep the complete page, not a cropped category square.
- Orient: record the issuer, date, district, and collection point.
- Classify: select one item and copy its exact Japanese category, including any 対象外 note.
- Schedule: find the matching collection day, deadline time, and any “do not put out” wording.
- Prepare: list the action verbs in order and check whether a special application is required.
Now cover your notes and answer four questions: What is the item? Which local stream accepts it? When and where may it be left? What must happen to it first? If one answer is missing, return to the official guide rather than filling it with a rule from another city. Save one complete phrase, such as キャップとラベルを外して出す, with the notice that made it meaningful. On a second notice, see whether you can recognize the same action even when the category or layout changes.
Kotoru is a local-first language-learning tool for learning from real audio, media, text, captions, photos, PDFs, and documents. Try Kotoru without creating an account with a notice you have the right to study, and keep the useful Japanese attached to its source. Use your municipality's current instructions for the actual disposal decision.
