These are sudajii acorns, also known as shiinomi. I picked them up this morning. I've selected the black ones, which have just fallen. I think there are about 600 pieces, weighing 500g. Please roast them in a frying pan until they pop, and then enjoy. They have a simple sweetness. To protect biodiversity, please refrain from planting them in other regions. Please use them for food or crafts. They will be sent via Nekopos.
