Place the daikon in a colander/mesh strainer over a bowl or the sink and sprinkle with salt. Mix well. Let sit for 30 minutes. Squeeze out excess water and then rinse well with cold water. Drain.  In a small saucepan, combine the seasoned rice vinegar, sugar and rice wine. Cook over medium heat, stirring constantly, until the sugar dissolves (this will only take a few minutes).  Transfer the daikon to an airtight container and pour the rice vinegar mixture over. Shake or stir well to combine. Chill for 20 minutes before serving.  This can store for up to a few days in the fridge, if it lasts that long. If desired, serve topped with crushed peanuts.
