Root Cause

Japanese garbage sorting is municipality-specific and strict. Tokyo's 23 wards typically have 3-5 categories (burnable / non-burnable / recyclable / oversized). Smaller cities can have 10-30+ categories (Kamikatsu, Tokushima has 45). Wrong-day or wrong-bag trash is left uncollected with a sticker (回収できません), often visible to neighbors. Designated transparent bags (指定袋) required in many cities.

Workarounds

  1. 92% success On move-in: get the local city's garbage calendar (gomi calendar / ゴミカレンダー) — multilingual versions available at most ward offices. Buy designated bags. Memorize sort categories: 燃えるゴミ (burnable, food/paper/wood), 燃えないゴミ (non-burnable, metal/glass/ceramic), 資源ゴミ (recyclable, PET/cans/cardboard), 粗大ゴミ (oversized, paid).

  2. 95% success PET bottle protocol: remove cap (separate plastic), peel label (separate plastic), rinse body, crush optional, place in clear bag, set out on PET day. Same for milk cartons (rinse, dry, flatten, bundle).

  3. 95% success Oversized item: call the local 粗大ごみ受付センター (search ward name + 粗大ゴミ), book pickup, buy the appropriate fee sticker at convenience store, attach to the item, set out on the booked day.

  4. 88% success If unsure: ask the apartment building's manager (管理人), or use the city's multilingual gomi consultation (Tokyo: tokyo-online.metro.tokyo.lg.jp). Most large cities have English/Chinese/Korean/Vietnamese gomi guides as PDF.

Dead Ends

Common approaches that don't work:

  1. Throw a bag mixing food scraps, plastic bottles, paper, and batteries into any street bin 85% fail

    Japanese curbside collection requires sorted bags by category and pickup day. PET bottles need cap removed, label peeled, body rinsed, and placed in PET-specific collection (often weekly, separate day from burnable). Batteries are toxic-waste category, NOT general trash. Non-conforming bags get rejected with a yellow sticker and remain on the street.

  2. Use any plastic bag for trash output 70% fail

    Many municipalities require designated transparent or city-branded bags (指定収集袋), purchased at supermarkets or convenience stores. Black opaque bags are rejected. Bag size also matters — fees are encoded into bag price.

  3. Set out a broken futon, microwave, or large furniture with weekly burnable trash 90% fail

    Oversized waste (粗大ゴミ, sodai gomi) requires advance booking with the city's sodai-gomi center, payment of a fee (300-3000 JPY per item via prepaid sticker), and pickup on a specific scheduled day. Just leaving a microwave at the curb is illegal dumping (不法投棄) — fines up to 10M JPY or 5 years prison under Waste Disposal Act.
