Yamagata Prefecture is known for producing Japan’s best cherries. When the fruit ripens in June, cherry farmers start work at the dark hour of 4 a.m. to bring in their harvest. They carefully hand-pick the cherries one at a time and ever-so-gently, place them in bamboo baskets called biku so as not to harm a single one. One by one, the harvested cherries are then carefully sorted by size and color, taken that same day to markets and shops, and displayed as Asatori Sakuranbo, or Morning-Harvest Cherries. The cherries are exceptionally popular across Japan as a gift of early summer.
