Tea farm in producing district KAKEGAWA CITY.
May I start by describing our standpoint of the green tea production process.
Once the tea leaves are picked, they become withered with the lapse of time.
It is the process of oxidization by nature. The leaves gradually change color from green to brown and then to red. The brown color denotes partial oxidation, as produced in China.
The color red denotes full oxidation and is called black tea, mainly produced in India.
- Oxidized tea is called black tea in India.
- Half oxidized tea is called Chinese tea.
- Japanese green tea is made without oxidization which stops enzymatic action.
So green tea can keep own vitamins which is good for health and the color of tealeaf does not lose chlorophyll. The green tea retains its vitamins and color of chlorphyll, which is good for health.

Citzens of Kakegawa have good health. The reason is that people drink several cups of green tea everyday. The catechins (antioxidant,immunity) in green tea are good for health. Catechins and vitamin C are water-soluble. Catechins are polyphenols of the flavonoid family.
After making tea, tea leaves still have βcarotene, Vitamin E, chlorophyll. So it is good to have tea leaves also. The green tea keeps inherent vitamins and catechin by nature and tea leaves produce the unique amino acid theanine from nitrogen fertilizers. Theanine is the source of taste and has a beneficial effect on our peace of mind.
