Walk down a household aisle here and a large share of the shelf is contents without a container. The numbers behind that are more complicated than they look.
The Japan Soap and Detergent Association reports that a refill pouch uses roughly 70–80% less plastic than the original bottle it replaces.
The same association also tracks total packaging plastic across its member companies. For its five main product groups, plastic use in 2022 was about 606,000 tonnes — roughly flat on the year, but 25.3% higher than in 1995.
Both facts are true. Per-unit packaging fell sharply; total volume rose because consumption grew. Refills are a real saving, not a solved problem.

They are the ordinary way many households buy shampoo, detergent and soap. The bottle is treated as equipment, not packaging.
Less packaging is part of it. So is weight, shelf space at home, and a familiar pump that keeps working. Several small reasons stack up.
Refills are made for particular containers and formulas. Mixing products in one bottle is not advisable — follow what the pack says.
Manufacturers generally advise emptying, washing and drying the container first. Topping up on top of old contents is not what the instructions describe.
Refills exist for cosmetics, seasonings, stationery and more. Once the format exists, it spreads across categories.
