Again this is a time when my lack of language skills are horribly apparent. I really do not know what Uricha is, but from its description it sounds like a compressed Balhyocha, which is a Korean Yellow/oolong tea. Neat little package as you can see above and below its a little ball but surprisingly dense.
This just advances my belief that Korea is a great practically untapped resource for high quality, and incredibly unique teas. For instance, have you ever tasted "salted roasted peanuts" before in a tea? Well through the first two infusions of this tea I could think of little else. If the vendor I received this tea from lists it, I will be sure to let everyone know as it is certainly a peculiar tea.
One thing I will say while it was quite highly compressed, breaking off pieces was not that challenging, and should I have had a tuo pick, it would have been almost childs play. (As close as working with a sizable and quite sharp "needle" can get to childs play.) I just happened to find a slightly looser spot and massaged it with my fingers and leaves started to flake off ever so slowly opening up a larger and larger patch of tea to get more leverage on prying off more leaves.
