Registration of Plant Protection Products in Japan

Plant protection products in Japan are regulated under the Agricultural Chemicals Regulation Act and approved if deemed safe in line with Good Agriculture Practice (GAP). Agrochemicals and biorationals are authorised strictly in accordance with their intended use, by specifying “application crop”, “application timing” and “application rate”. Farmers are only allowed to use plant protection products under the approved conditions of use.

Re-evaluation programme

Until recently, agrochemicals in Japan were subject to re-registration every three years. With time, the necessity for the regulatory plant protection reform in Japan became pressing,  as the market required more flexibility from the regulatory regime to integrate the latest scientific approaches and common agricultural practices. This was further accelerated by the widening gap between the regulatory requirements in Japan and new harmonised assessment guidelines increasingly applied internationally. Countering this, the Japanese government amended its Agricultural Chemicals Regulation Act on December 1st, 2018 by introducing a re-evaluation programme for active substances in the existing plant protection products.

The re-evaluation programme regulates the revision process by setting out clear timelines:

  • Plant protection products registered after enforcement of the amendment act require re-evaluation approximately every 15 years
  • Existing plant protection products are re-evaluated from 2021 according to a priority order.
