What we call "Sakura-cha" in Japanese.
Served in some events which people would like to celebrate e.g. someone graduate from or get in school, get a job, marriage etc. Never at a funeral.
Cherry blossom flowers for this tea are pickled in some salt, so this tea tastes salty. We have some other "salty" teas e.g. "Kobu-cha" ( sea weed tea ). I guess perhaps "salty" teas are Japan original? Never heard any "salty" teas abroad or I just don't know any?
