Place all vegetables, apples and sea salt in a mixing bowl and gently knead with your hands to mix. Place in a Japanese pickle press, available in many health food stores and press for 2 hours or more. If a pickle press is not available, mound the salted vegetables in the center of the mixing bowl, place a plate upside down on top of the vegetables and set a large glass jar (1/2 to 1 gallon) filled with water on top of the plate to apply pressure. Press for 2 hours or more. With your hands squeeze out liquid from the vegetables. Taste, if the vegetables taste salty rinse under cold water and squeeze again to remove the salty taste. Place in a serving dish, add the vinegar and mirin. Toss to thoroughly mix before serving.
