Edwards Tea Co., Ltd., a major Japanese tea brand, has reconstructed a legendary tea recipe said to have been brought to Japan via Nanban trade in the late Edo period, using historical documents and antique coin research. The limited-edition 'Nanban Kocha: Edo no Shizuku' was released in collaboration with three heritage tea merchants, with a collector's set (gift tin + replica antique coin) selling out within 72 hours of pre-order launch.
