Overview:
Fukamushi-sencha (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 they 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 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 (FL1 to FL5) of fukamushicha and photos of 2 of the grades can be found on the website.

CHAMART will be able to provide 3 grades of fukamushicha Powder too.

FL4 is the 4th grade and the variety is Yabukita. Tea leaves plucked in spring are used.

FL5 is the 5th grade and the variety is Yabukita. Tea leaves plucked in autumn are used.

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 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.

Factory processing:
Cooling organic fresh tea leaves in a container → Steaming fresh leaves at around 100℃ by machine (蒸熱 Jonetsu) → Scattering and drying tea leaves (葉打ち Hauchi) → Primary rolling and drying of tea leaves by machine (粗揉 soju) → Rolling tea leaves by machine (揉捻 Junen) → Secondary rolling and drying of tea leaves (中揉 chujo) → Final rolling of tea leaves by machine (精揉 seiju) → Drying tea leaves by machine (乾燥) → Sieving tea leaves by machine (篩い分け Furuiwake) → Storing tea leaves in the refrigerator → Firing and refining tea leaves by machine (火入れ hiire) → 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 Fukamushicha:
There are various ways of enjoying fukamushicha.
Fukamushicha is good to drink as it can also be enjoyed with dried fruit or mint leaves added too.
Moreover, the used tea leaves of fukamushicha can be used for cooking with eggs, cheese, yogurt, pasta, etc.

*Shizuoka’s Chagusaba farming method (Traditional Tea-grass Integrated System in Shizuoka)
静冈的茶草场农耕法/靜岡的茶草場耕法
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.

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.
