At Ichikawaen, every stage of tea production — from cultivation and harvesting to roasting, blending, and final inspection —
is managed with integrity and precision. Our skilled production team carefully monitors each process without compromise,
preserving the natural aroma, flavor, and safety that define authentic Ichikawaen tea. We believe that true quality is not
something verified at the end, but something built carefully into every step from start to finish.
“Chashi” conducts equipment inspections and checks each step of the production process.
Raw materials (crude tea) are stored in cold storage at −20°C to maintain freshness.
Air showers and adhesive rollers are used to remove contaminants such as dust and hair from clothing.
A metal detector is installed at the final stage of the manufacturing process to eliminate metallic foreign objects.
At delivery entrances and sanitary zones, sheet shutters that block ultraviolet light and have insect-repellent properties are installed.
The delivery entrance is equipped with double shutters featuring an interlock system.
A tea component analyzer is used to check the components of raw materials (crude tea) and finished products.
