It is deep steamed tea representing tea ceremony, Shizuoka Makinohara.
Since steaming time is longer than usual (2 to 3 times), the tea leaves become uneven by that amount, but the extractability of tea well improves richness and taste.
It is a tasty green tea with no tired everyday being drunk at the tea factory.
It is a popular item sold at supermarket nationwide, 10000 shops.
I use a stand type tea bag with a chuck convenient for storage.
