Product Information Kakegawa Fukamushicha (deep-steamed green tea)

Fukamushicha (深蒸し茶) is deep-steamed green tea and one type of sencha (煎茶). In Japan, medium-steamed green tea is called sencha (steaming time is 30 to 50 seconds), and deep-steamed green tea (steaming time is 60 to 120 seconds) is called fukamushicha. Fukamushicha has been produced since around 1955 on the Makihohara Plateau in Shizuoka Prefecture. The insoluble components such as vitamin E, β-carotene, chlorophyll, etc. can be consumed more easily from fukamushicha than from medium-steamed green tea. The used tea leaves are very soft and tiny, thus it can be used for cooking.
The story of the beginning of fukamushicha is here.

The fukamushicha which CHAMART introduces is single origin and certified as Organic JAS. The fukamushicha is produced in Kakegawa City, Shizuoka Prefecture. Kakegawa is famous for fukamushicha.
The tea leaves of fukamushicha 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 fukamushicha is eco-friendly tea and CHAMART calls the fukamushicha “CHAGUSABA tea”.

CHAMART introduces 5 grades of fukamushicha.

The fukamushicha is the forth-grade one.

The fukamushicha is the third-grade one.

Variety: Yabukita
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.

Producers of tea:
A family-run tea garden that manages the production of tea from cultivation through processing.  The tea farmer’s teas were awarded 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.

*Shizuoka’s Chagusaba farming method (Traditional Tea-grass Integrated System in Shizuoka)
The Chagusaba farming method is a farming method traditionally practiced in Shizuoka Prefecture using grass mulch.  It is an example of circular agriculture that harmonizes humans’ relationship with nature to preserve the environment and protect biodiversity.
Shizuoka’s Chagusaba farming method, which is conducted in 4 cities and 1 town including Kakegawa City, has been recognized as a Globally Important Agricultural Heritage System (GIAHS) by the Food and Agriculture Organization of the United Nations (FAO) in 2013.*

Cha (茶) means tea, Gusa/Kusa (草) means grass, and Ba (場) means place. Chagusaba (茶草場) refers to the semi-natural grasslands around tea fields. The Chagusaba farming method makes use of natural resources by cutting pampas or bamboo grasses that grow around the tea fields and laying them in the furrows between the tea fields. These grasses used in the tea fields are called Chagusa (茶草).

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.

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.

Grass mulch farming was once conducted all over Japan. However, it is a burden on tea farmers. Thus, the number of tea farmers who conduct grass mulch methods has been decreasing.

*Globally Important Agricultural Heritage Systems (GIAHS)

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 2 sites in China, 1 site in Japan and 1 site in South Korea.

*Organic JAS:
The JAS (Japanese Agricultural Standard) System is based on the Law Concerning Standardization, etc. of Agricultural and Forestry Products (Law No.175, 1950) which governs all the agricultural and forestry products, except for liquors, drugs, quasi-drugs and cosmetics. The Organic JAS system has been further developed with the addition of the JAS Standards for organic livestock products, organic processed foods of animal origin and organic feeds which took effect in November 2005.

Japanese tea certified as Organic JAS is considered to conform to equivalent standards as EU produced organic goods and Japanese tea labeled as Organic can be imported to EU if the product satisfies fixed conditions. However, it does NOT mean that the Japanese tea can be certified as an EU organic food.
