I want to throw away a large amount of garbage from moving or organizing artifacts at once.

A large amount of garbage due to moving or organizing relics is not collected at once because it will interfere with normal collection if it is sent to the collection site.
How to dispose of such a large amount of garbage is as follows.

Items that have been separated based on the classification rules of Yokohama City can be brought in by yourself.

burnable garbage can be brought directly to four incineration plants in the city. You need to apply in advance at the Resources and Waste Recycling Bureau office in your ward. In addition, a fee of 13 yen per kilogram will be charged.
For more information, please contact the Resources and Waste Recycling Bureau office in your district.

Recyclables such as recycle paper and plastic containers and packaging (*) can be brought to the Center Recycling, which is carried out by the Resources and Waste Recycling Bureau office in each district.
（※） Plastic resources are available in Asahi Ward, Izumi Ward, Isogo Ward, Kanazawa Ward, Konan Ward, Sakae Ward, Seya Ward, Totsuka Ward and Naka Ward since October 1, 2024.
For more information, please contact the Resources and Waste Recycling Bureau office in your district.

oversized garbage can be brought directly to four self-loading yards in the city. You need to apply in advance at Oversized Garbage Reception Center to bring your own. In addition, the same fee will be charged as the city collects.
For more information, please contact Oversized Garbage Reception Center.

Please contact the general waste collection and transportation business licensed contractor directly and request processing.
Alternatively, please contact the Yokohama City General Waste Permit Business Cooperative (Phone number: 045-662-2563). We will guide you to a licensed supplier. Please note that fees and types of items that can be processed vary depending on the vendor, so please contact each vendor.
