How to Dispose of a Microwave in Japan
How to Dispose of Microwave Oven in Japan
Measure the microwave: width, depth (including handle), and height including any feet/legs.
Check your ward's size threshold (most Tokyo wards: 30 cm on longest side; some use 50 cm — check the ward website).
If under threshold: clean the interior, bag in a large non-burnable garbage bag (or as-is at the collection station).
If over threshold: book as bulky waste through your ward's online portal.
Turntable glass plate: remove it — it counts as non-burnable waste separately (or burnable if it breaks).
General Rules Across Japan
Microwaves are NOT covered by the Home Appliance Recycling Law. Most Japanese municipalities classify them by size: under the ward size threshold → non-burnable waste; over the threshold → bulky waste. Microwaves with built-in convection or steam functions are treated the same way.
Tokyo-Specific Notes
Tokyo ward size thresholds for non-burnable waste vary slightly: Shinjuku, Shibuya, Setagaya: 30 cm rule (longest side under 30 cm = non-burnable). Minato, Chuo: 50 cm rule. Always check your specific ward's website.
✅ Practical Tips
- Measure including the handle (取っ手) — many people forget this and underestimate the total depth.
- Clean the microwave thoroughly before disposal — food residue can attract pests to the collection station.
🔄 Alternatives to Throwing Away
- Working microwaves: Sell on Mercari or donate to local second-hand shops. Under 5 years old with no damage, they are popular on resale platforms.
