Overview:
Matcha (抹茶) is NOT powdered sencha (steamed green tea). The ingredient of matcha is tencha (碾茶), which is a green tea cultivated and processed by a special method. The tea leaves for tencha are covered by straw mats or black cloth for 3 weeks or more to block the sunlight before plucking. The tencha leaves are steamed, but not rolled like sencha during processing. The leaves keep their bright green color which creates matcha’s distinctive color.

The matcha is single origin and certified as JAS Organic. CHAMART introduces 8 grades of matcha.
The matcha is produced in Kakegawa City, Shizuoka Prefecture.
The tea leaves are cultivated by the Chagusaba farming method which was recognized as a Globally Important Agricultural Heritage System (GIAHS) by the United Nations in 2013.*
This matcha is eco-friendly tea and CHAMART calls the matcha “CHAGUSABA tea”.

CHAMART introduces 8 grades (M1 to M8) of matcha and photos of 6 of the grades can be found on the website. Grades M1 to M4 are of ceremonial grade.
The color of matcha varies slightly with each lot. Thus, the color of the matcha that will be shipped out might be slightly different from that in the photos.

Varieties and times of tea leaf plucking as of April 2025
M2 is the second grade and M3 is the third grade. The variety of M2 and M3 is Saemidori.
M4 is the fourth grade, and its varieties are Yabukita, Sayamamidori and Meiryoku.
M2, M3, and M4 are ceremonial grade.
M5 it the fifth grade and M6 is the sixth grade, and its variety is Yabukita.
M1, M2, M3 and M4 are ceremonial grade.
The tea leaves of M1, M2, M3, M4, M5, and M6 were plucked in spring.
M7 is the seventh grade and M8 is the eighth grade. The variety of M7 and M8 is Yabukita. The tea leaves of M7 and M8 were plucked in autumn.

Yabukita is primarily used for many grades, but each grade has a different variety. The variety may change each year to produce better matcha.​
Yabukita is the most popular variety of tea plant in Japan. Yabukita is a well-balanced variety, with a high yield and has a strong umami flavor. Yabukita is suitable for any kind of green tea.
Saemidori is an excellent quality variety with bright green color, luster, and strong umami, but less astringency. Saemidori is a hybrid of the Yabukita and Asatsuyu varieties.
Sayamamidori is a tea variety with thick, dark green leaves and a unique, mature flavor.
Meiryoku is a variety with dark green leaves, and its brewed tea has a yellow-green color. It has a unique flavor with a hint of astringency.

CHAGUSABA farming method *: ◯
The tea is cultivated using the CHAGUSABA farming method in Globally Important Agricultural Heritage Systems (GIAHS) recognized areas.
*The CHAGUSABA farming method is NOT an organic farming method.

Producers of tea:
A family-run tea garden that manages the production of tea from cultivation through processing. The tea farmer’s teas have received awards at multiple national and international tea contests.
The philosophy of the tea farmers is respect for nature and cultivating tea. They do not want to destroy the ecosystem using agricultural chemicals. Thus, they don’t use any chemicals for their tea cultivation.

They mix Chagusa (grasses around the tea fields) and rice bran with soil and compost them to make nutrient rich soil. Microscopic organisms work in the mixture and it becomes organic compost. The soil is put into their tea fields.

Overall processing:
The tea leaves for tencha, which is the raw material of matcha, are plucked around the beginning of May in Kakegawa City. The tencha tea fields are covered with man-made black mats to block sunlight for around 3 weeks before the tea leaves are plucked (poles are not used to support the mats in the tea fields).
When the sunlight is blocked, catechin (bitterness components) development is suppressed, and amino acid (umami components) development is promoted. Tencha tea leaves are steamed, but unlike sencha (steamed green tea) are not rolled.
The tencha is then ground by a bead or ball mill into a fine powder.
The tencha is produced from leaves picked during the year, and stored in the refrigerator for a while to allow the matcha to ripen and improve the richness and mellowness of its flavor.

Factory processing:
Cooling organic fresh tea leaves in a container → Steaming fresh leaves at around 100℃ by machine → Drying the tea leaves by machine → Sieving the tea leaves by machine → Drying the tea leaves by machine → Measuring and packing the tea leaves (tencha) → Storing the tea leaves in the refrigerator → Grinding the tea leaves (tencha) by a stone mill or bead (ball) mill → Inspecting, measuring, packing and shipping

Production place: Kakegawa City, Shizuoka, Japan
Shizuoka Prefecture is a major tea production area of Japan, located in the center of the main island of Japan. Shizuoka Prefecture has a warm climate with many rivers and is often foggy. These conditions are suitable for tea cultivation.
Kakegawa City is one of the major tea production cities in Shizuoka Prefecture and is especially famous for fukamushicha. There is Mt. Awagatake with Chamonji (茶文字). The letter “茶” (tea) has been created by planting 1,000 Hinoki trees (Japanese cypress) on the slope of Mt. Awagatake. The dimensions of the letter “茶” (TEA) are about 130 x 130 meters. It is a symbol of Kakegawa City. The Chamonji was created with pine trees for advertising tea in 1932 first, but the trees were blighted by pine weevils. Then, the Chamonji was created with 1,000 Hinoki trees again in 1985.
There are many facilities related to tea such as tea museums, a tea-themed hotel, etc. in Shizuoka Prefecture.

How to use matcha:
Matcha can be used for various purposes.

The grasses laid in the furrows are fluffy and look like a Japanese futon (like a duvet). The Chagusa gradually breaks down to become compost. In addition, the laying of Chagusa makes it difficult for weeds to grow, and prevents moisture evaporation and the soil from being displaced by rainwater.

Maintain the environment and biodiversity
Tea farmers cut pampas or bamboo grasses in autumn and winter, dry them and cut them into smaller pieces. During the winter, tea farmers put the Chagusa into the tea fields. By cutting the tall pampas or bamboo grasses around the tea fields, small animals and plants are given access to sunlight, allowing them to thrive.

Drink LEAF TEA and Protect Nature
Grass mulch farming was once conducted all over Japan before. However, it is a burden on tea farmers and the market price of leaf tea isn’t stable today. Thus, the number of tea farmers who conduct grass mulch methods has been decreasing.
You can support the tea farmers by purchasing and drinking the tea cultivated by the Chagusaba farming method. Consequently, you will contribute to maintaining the environment and biodiversity.

*Globally Important Agricultural Heritage Systems (GIAHS)
全球重要农业文化遗产/全球重要農業文化遺產
Systèmes Ingénieux du Patrimoine Agricole Mondial (SIPAM)
GIAHS are traditional agroecosystems made up of communities that have lived in an intricate relationship with their territory across generations while adapting to changes in society and the environment. They are recognized by the Food and Agriculture Organization of the United Nations (FAO). Additionally, the systems are resilient, characterized by remarkable agrobiodiversity, traditional knowledge, invaluable cultures and landscapes, sustainably managed by farmers, herders, fisherfolk, and forest people in ways that contribute to their livelihoods and food security.
FAO has designated a GIAHS related to tea in 3 sites in China, 1 site in Japan and 1 site in South Korea.

*Tea leaves contain caffeine. The diuretic, stimulant and anticancer effects of caffeine intake are clinically recognized. On the other hand, excessive intake of caffeine may have a damaging effect on health. Especially, pregnant or breastfeeding women, and children should be careful with the amount of caffeine they intake.
