Key takeaways
  • It's not just glyphosate — pesticides that have been banned or restricted overseas, such as chlorpyrifos, are still in use in Japan.
  • Chlorpyrifos is an organophosphate pesticide that affects the nervous system, and it has been banned in the EU and in some U.S. states.
  • There have been reports of it appearing in breast milk and dispersing into the air, raising concerns about possible effects on pregnant women and children.
  • Be mindful of both home-grown produce and commercially available pesticides. Let’s wash thoroughly, peel when appropriate, and consider alternative pest-control methods.

Pesticides Banned Overseas Are Still Used in Japan: The Current Situation and Issues We Need to Address

As we covered earlier with Roundup’s active ingredient glyphosate, regulation is now advancing worldwide for organophosphate insecticides like chlorpyrifos. The European Union has banned chlorpyrifos, and in the United States a number of states have followed with their own bans. In Japan, by contrast, several of these chemicals are not completely prohibited — there are limits such as dilution requirements and restrictions on the number of applications, but no full ban. This isn’t just something to file away as trivia; it’s an issue that directly affects our everyday lives and our health.

Chlorpyrifos — what it is, and other active ingredients to watch out for

Key characteristics of chlorpyrifos

Chlorpyrifos is an organophosphate insecticide that kills insects by disrupting their neural transmission. Because it has been widely used for termite control and crop protection, overall usage has been high, and it is notably toxic. Research has pointed to increased risks of developmental disorders and other neurological conditions, and we are particularly concerned about effects on pregnant women and young children. The epidemiological and toxicological evidence is what underlies regulatory actions in Europe and the United States.

Major organophosphates available for use in Japan (examples)

Examples include acephate — banned in the EU; diazinon — residential use is restricted in some areas; Kazusafos — has been banned in France in certain cases; and profenofos — not approved in the EU. We should also pay close attention to the ingredient labels on over‑the‑counter household insecticides.

Health Risks and Environmental Spread

Effects on the human body

Because organophosphate pesticides act on the nervous system, research suggests they can cause not only acute poisoning but also developmental disorders and declines in cognitive function from chronic low‑dose exposure. In some studies, concentrations exceeding safety limits have even been detected in breast milk, making exposure during pregnancy and infancy particularly serious.

The Reality of Atmospheric and Environmental Dispersion

Because sprayed material can drift and wash into soil and waterways, we've seen residues detected as close as 10 meters and as far as over 100 meters from the treated fields. Since this can affect the air we breathe every day, nearby parks, and our home vegetable gardens, it's sometimes a false sense of security to assume, "the spraying is happening far away."

Preventive Measures and Alternatives You Can Do at Home

Checklist: What to Check Before Buying and While Using

Before buying store-bought pest-control products, check the ingredient list. If the label says “organophosphate” or lists chemical names such as chlorpyrifos, acephate, or diazinon, take extra care. When using these products, pay attention to wind direction and nearby neighbors, ensure good ventilation, and wear gloves and a mask. When our team actually reviewed how we handle commercial products, we found that simply reading the instructions carefully helped reduce the risk.

Practical measures for your home vegetable garden

- Non-chemical pest control: trying companion planting, insect traps, or physical insect netting can be effective. - Washing and peeling: rinsing thoroughly under running water and peeling when possible will reduce residues. In our own kitchen tests, rinsing and scrubbing under running water did remove a portion of residues, but not completely. - Choose organic or reduced-pesticide produce: when you have options, selecting items labeled organic or reduced-pesticide is a good way to lower risk.

Consultations with government agencies and experts

If pesticides are being sprayed in your area, it's a good idea to notify or consult your municipality's agricultural department or the consumer advice/consultation desk. If you're worried about spraying near your home, you can also consider talking with a medical provider or your local public health center.

Summary

After glyphosate, the fact that pesticides such as chlorpyrifos—substances increasingly restricted overseas—continue to be used in Japan is a reality we cannot ignore when it comes to our health and living environment. A complete solution depends on action from government and industry, but at the individual level we can lower our risk by checking product ingredients, using products correctly and ventilating properly, and adopting alternatives in home gardening. We at the geefee team will keep sharing information as we gradually expand the choices we can make in dailylife. Please start by checking the labels on the products you use every day.
