We purchase raw materials for our products from manufacturers that have met the standards
set by the Japanese government (Japanese Pharmacopoeia). Additionally, we control the
quality of our products by conducting our verification tests in accordance with the law.
Similarly, for materials used in products, such as bottles and caps, we conduct quality
inspections for confirmation. We perform testing and inspections of ingredients and materials
and conduct final testing of our finished products to ensure that they meet a specific level of
quality.
Furthermore, we ensure that everything related to the products we manufacture meets the
standards, including the management of water used in manufacturing, the management of
testing equipment, and the monitoring of products released to the market to ensure their
stability until their expiration date.
