Value Village ／ Everyday know-how

Japan is known abroad for two contradictory things: a word, mottainai, that means "what a waste", and packaging so elaborate that a single sweet arrives in three layers. Both are real, and the tension between them is where policy has moved in the last decade.
| Item | Figure | Source |
|---|---|---|
| Plastic waste per person | about 32 kg a year — second highest in the world after the US | UNEP (2018) |
| Plastic bag charge | From 1 July 2020; bag refusal rate rose from ~30% to over 70% | Ministry of the Environment |
| Plastics Resource Circulation Act | April 2022: 12 single-use items (cutlery, straws, hotel amenities, hangers) to be reduced by large providers | same |
| Food loss | 4.64 million tonnes (FY2023), about 38 kg per person | MAFF / MoE |
| PET bottle collection rate | about 95%; recycling rate about 86% | Council for PET Bottle Recycling |
| "Mottainai" | Popularised internationally by Wangari Maathai (2005) after visiting Japan | — |
[Verify] Waste figures with UNEP and the Ministry of the Environment; bag-refusal rates with the MoE's 2020–21 surveys; food loss with MAFF's latest estimate.
It means regret at waste — of food, effort, things. Recycling is one response; not buying, using up, repairing and repurposing are the older ones.
Per-capita plastic waste is among the highest in the world. What Japan does well is sorting and collection (see the waste article); what it did badly was generation, and that is what the 2020–22 laws target.
It grew from courtesy and hygiene; the individually wrapped sweet stays fresh in a humid summer and can be shared at the office. The excess is real; the reasons were not frivolous.
Bag refusal over 70%, cutlery on request, hotel amenities off the room, thinner gift wrapping. The change since 2020 is visible at every till.
Wangari Maathai carried the word to the UN in 2005 as a summary of reduce, reuse, recycle and respect. The household habits it names exist in every frugal culture; Japan simply kept the word.
