To protect consumers' health, Japan's pesticide residue standards for tea imports are very strict. As of May 2021, Japan's pesticide residue standards for imported tea are as follows:

1. Tea polyphenol compounds: not to exceed 10 mg/kg

2. Herbicides: not to be detected

3. Insecticides: not to be detected or not to exceed 5 mg/kg

4. Fungicides: not to be detected or not to exceed 5 mg/kg

Each batch of tea is subjected to rigorous testing, and only tea that meets these standards can be sold in the Japanese market. Therefore, consumers can purchase and consume imported Japanese tea with confidence.
