Sodai Gomi: How Bulky Waste Works in Japan

What counts as sodai gomi

Sodai gomi means large household waste that does not fit normal collection rules. The exact size threshold differs by municipality, but many cities use a rough limit around 30 cm to 50 cm in one dimension.

Common examples include futons, mattresses, bicycles, small furniture, shelving, suitcases, and large plastic storage boxes. Some items that look bulky are excluded because a special law applies, especially the four main home appliance categories.

The normal process

The workflow is usually booking first, payment second, pickup third. You apply online or by phone, describe the item, receive a fee or ticket instruction, buy the sticker at a convenience store or other approved seller, write the booking number if required, and attach it visibly.

• Measure the item before booking.
• Check whether the city collects it or whether a retailer must take it.
• Book early before moving season.
• Put it out on the appointed morning, not days before.
• Do not remove other people's stickered items from the collection point.

The mistakes that waste the most time

The biggest mistake is treating bulky waste like normal garbage. A sofa without a booking sticker will usually stay put. Another common mistake is booking too late in March or April, when moving demand fills slots.

For items in usable condition, selling, donating, or retailer pickup may be faster than municipal pickup. For items covered by appliance recycling law, municipal bulky waste is the wrong path entirely.
