TRACEABILITY
The cultivation management records of tea growers are checked, with particular emphasis on the section related to pesticides. We have established a system for tracking the date and time of production, raw materials, and even the cultivation status of farmers from the lot number printed on the product that the customer receives. The "Traceability Records" received from the suppliers is checked to verify the cultivation methods, processing methods and management at the tea gardens to ensure that the raw materials used comply with the rules and regulations.

PRESERVATION AND STORAGE
Complete control of temperature and humidity using large freezers
The tea leaves harvested each year are put in the bags filled with nitrogen, and stored in special freezers at 0℃ (±1℃) with humidity less than 50% to maintain the freshness of the new leaves.
Storing in proper temperature in the freezers for a certain period of time matures tea leaves and enhances umami in them, resulting in teas rich and mellow in taste.
