Choose Japanese eggplants for harvest when they are at least as large as a finger, shiny and have a rich, deep purple color.
Place a basket or tray within easy reach of the plants. Put on garden gloves to protect your hands.
Cut the stem right above the top of each eggplant with garden shears or a sharp knife to remove the eggplant.
Place the harvested eggplants carefully on the tray or in the basket in a single layer to prevent bruising.
Rinse off the eggplants under cool water, and store them in the refrigerator, in the vegetable crisper.
