Ureshino-cha from Saga Prefecture in Kyushu is a type of tea called tamaryokucha.
Tamaryokucha (literally “ball green tea”) is a type of sencha that skips the very last part of the rolling process that extends the leaves into needles. As a result the leaves as they dry will curl slightly. Traditionally, it was this process that was used when export sencha to Russia during the 1930s. At first, this was done in order to imitate Chinese gunpowder green teas, and was a huge hit in Russia, then Morocco where it was drunk with mint (as is done today primarily with Chinese teas).
