Kinds of Tea

Even tea is different in production method, areas, timing, varieties, etc. in terms of kind. There are these main types of tea: fully-oxidized tea such as English tea, partially-oxidized such as oolong tea and non-oxidized such as japanese green tea. Since most tea leaves are processed into japanese green tea in Japan, we often call it "Japanese tea".
Shizuoka, Kagoshima and Mie are well-known producers of Japanese tea, and tea leaves grown in our area of production, Mie, are called Ise-cha.
The main types of Ise-cha are "kabusecha (covered tea)", "fukamushi-sencha (deep-steamed japanese green tea)" and "Sencha (steamed japanese green tea)".

Tea made from tea leaves that are grown in the shade by covering the tea plantation from direct sunlight for a certain period of time


Powdered japanese green tea. After grown by blocking sunlight and steamed, matcha is made from tencha, dried tea leaves after veins of leaves are removed. Tencha is ground with millstone into a fine powder. Not only it is used in tea ceremony but also used to make Japanese-style confectionery and Western-style cake and used as an ingredient for various cuisine.


Ohicha is tea whose leaves are grown in the shade by covering before harvesting them. This suppresses the astringent taste and increases umami (flavor) of the tea. Gyokuro is a top quality product; the leaves are covered about twenty days.


Kabusecha is a high-end product almost like gyokuro. The tea leaves are covered for from one to two weeks, and you can enjoy the flavor close to gyokuro. It features the beautiful color of green and mild flavor because the amount of amino acids increases by covering the leaves.


Tea made from tea leaves that are grown without covering


Fukamushicha is almost as same as sencha introduced in the next section but steamed longer. Steaming more deeply makes it powdery and rich in flavor.


This is the most popular japanese green tea. The leaves are picked after grown without covering, thus it has the flavor in bitterness. Historically, sencha was made by boiling, not infused in the teapot we do today.

How to Prepare Japanese Tea(Kabusecha)

Here we introduce how to prepare "kabusecha" as one example. There are other methods of preparation you can enjoy, and it differs depending on the kind. In order to give off a strong flavor and rich aroma, it is popular you take time to make the tea with samashiyu (cooled down boiled water).

Second Brewing

How to Prepare Japanese Tea (Second Brewing)

After you pour back the cooled-down water in the teapot, wait for 30 seconds in Step 4. You can enjoy great flavor of the tea even with the second brewing.

Tea Concentration and Flavor

After poring hot water, tea gets stronger over time as a matter of course. You can draw out clear flavor and aroma of the tea when brewing by taking time with samashiyu as previously introduced.
If you wish to drink lighter tea, you brew it with hotter water in a short time, and if you wish to enjoy some bitterness, you brew it with water somewhat hot and pause a moment.
You can choose however you would like to drink tea, but there is some data below as objective facts.

Umami of tea (amino acids, amide, theanine, etc.) begins to dissolve even at 60 degrees Celsius.
Astringency of tea (tannin, caffeine, etc.) begins to dissolve more at 80 degrees Celsius.

In short, "astringency" (bitterness) increases at a higher temperature, and "umami" increases at a lower temperature. Bancha, hojicha and genmaicha draws faster.

The longer the stronger.
The longer the bitterer. The shorter the milder.

Virtue of Japanese Green Tea

Japanese japanese green tea has a diverse range of effects. Not only does it have major vitamins but also contains valuable components that other foods may not offer.
Especially, catechin, astringency of japanese green tea, has antioxidant effects far stronger than commonly used antioxidant, and it suppresses active oxygen that is said to cause many illnesses.
Japanese japanese green tea is not just delicious; it is a fully nutritious non-calorie drink. Just drinking a cup of tea after meal every day gives you a variety of benefits.

Virtue of Japanese Green Tea
  1. Preventing Cancer - Catechin, which accounts for 10-18% of japanese green tea components, has antioxidant effects far stronger than antioxidant and suppresses active oxygen. Moreover, some reports show it has effects that eliminate cancers, so not only is japanese green tea a healthy drink but also it attracts attention as an anti-cancer agent.
  2. Ameliorating Life-style Related Diseases - Fat intake increase causes various symptoms such as cardiac infarction, stroke and diabetes. Cholesterol is left in the blood when you eat too much food with it. Bancha is said to have effects that reduce a blood glucose level and prevent diabetes. Making bancha with cold water extracts more effective components.
  3. Preventing Cavities and Bad Breath - Catechin in japanese green tea has antioxidant effects that prevent cavities and bad breath. It prevents formation of dental plaque, and minerals and fluorine that unite with enamel make your teeth stronger. It prevents cavities by developing a habit to drink japanese green tea after meal, and it also prevents bad breath by gargling with japanese green tea after tooth-brushing.
  4. Beauty Effect - Your body oxidizes (= gets old) when a large amount of active oxygen is produced; your skin loses moisture that causes wrinkles and sag. Catechin suppresses the production of active oxygen, and vitamin C, one of the components in japanese green tea, prevents pigmentation of melanin which keeps the skin fair. Carotene has the same actions as vitamin A that keeps your skin moisturized.
  5. Diet Effect - Since japanese green tea has components such as dietary fibers that are insoluble in hot water, 70% of the nutrition is discarded by just making regular tea. Thought catechin suppresses blood cholesterol, making tea with powdered tea leaves or using them in cooking makes japanese green tea an ideal non-calorie drink containing dietary fibers.
  6. Relaxation - Theanine, an umami component in japanese green tea, has a relaxation effect that soothes the nerves and revives tiredness of body and mind by directly acting on the brain. At the same time, caffeine in japanese green tea has excitation effect, but theanine has an action that adjusts the effect. Also the aroma of japanese green tea gives us comfort.
