In Japan, "tea" is commonly green tea.
Unlike black tea, Japanese green tea is made by steaming the picked leaves and blocking the fermentation of the leaves. So the leaf of tea is dark green and drawn tea is green or yellow.
Green tea is slightly bitter, but we never add sugar or milk when we drink it.
At tea break, Japanese people drink not only coffee or black tea but
also green tea, of course.
Additionally Japanese people drink the tea, after meal or during the desk work.
Plastic bottles of green tea are bought very well, and many people satisfy their thirst with green tea whenever and wherever they wanted.
When a guest visit us, we make a cup of tea for the guest first.
It is one of the customs of hospitality.
This custom is done at most Japanese restaurants and ryokans.
When you go into a restaurant, a waiter/waitress brings a cup of tea (or water) for you first.
When you are led to your room in a ryokan, the attendant serves a cup of tea for you first.
Of course, they are free service.
(Some restaurants say "Help yourself to drinks.")
But you shouldn't go into a restaurant only to drink the free tea.
"Sencha" is the classification of common Japanese tea and means brewed
When you travel in Japan, you can taste this at any restaurant, hotel or ryokan. It is commonly drunk at home.
Sencha is made of young tea leaves, but there is cheap "bancha" made of grown tea leaves. It tastes milder than common sencha.
By contralies, there is premium "gyokuro" that the tea leaves are grown carefully.
"Maccha" is powdered tea, and generally it is mainly served at tea
Unlike sencha, it is dissolved in hot water and is frothed with a small whisk made of bamboo.
It is bitter but feels creamy.
"Hojicha" is roasted the leaves of sencha.
Drawn hojicha has red-brown color like black tea. It tastes milder than sencha.
"Mugicha" is the tea made from roasted barley, not tea leaf.
Mugicha is usually served cold in summer. It is caffeine free.
