Yoku Moku cookies are my favorite. I order them from Neiman Marcus every year for Christmas since the only brick and mortar located in the states is New York. You might be able to find a couple varieties offered at Japanese markets and specialty stores statewide. Cookies are light, buttery not too sweet giving the perfect balance and texture in each bite. Easy to get to and located inside of Tokyo Station along side many other shops, this one is not to miss. A small corner shop offering limited edition Yoku Moku and cakes along side its popular choices. This location also offers a small café with dessert options. Come early as they run out of the best selections early in the day.
