Because We Drink Tea Every Day Quality Control System

ITO EN does not use tea leaves of unknown provenance. ITO EN works with tea farmers to ensure we understand their growing methods. It can do this because ITO EN is all about tea.

Further, with Oi Ocha, ITO EN has established a mechanism for grasping everything from finished product to manufacturing plants, from production date, to raw materiales and to how the tea leaves are cultivated.

This mechanism for tracking production history is called "Traceability".

Oi Ocha produced under this end-to-end management process is tested daily by quality managers using the latest equipment, as well as through sensory testing of qualities such as flavor and aroma that cannot be determined by machine.

Ensuring Safety and Security in Product Manufacture

The ITO EN Group has established polices on procurement and quality management, and is working in collaboration with its stakeholders (including outsourced beverage producers) to establish a supply framework that pays due care and consideration to both environmental and social aspects.

Our procurement policy sets guidelines for the pursuit of quality, safety and peace of mind, fairness in procurement and consideration for human rights, labor and the environment. Our quality management policy dictates rules for the provision of safe and reliable products, compliance with applicable laws and ordinances and for ensuring safety of products utilizing international standards. On the quality management front, we have acquired international certifications such as ISO9001 for quality control and quality assurance and FSSC22000 for food safety at our beverage and leaf manufacturing factories in Japan, and have established and are operating a quality control system in line with relevant laws and guidelines.
