I want to get return bucket even though the count is 0. How to get daily histogram buckets with 0 count??

My aggregation query is below. I want to every histogram buckets from last Sunday to Saturday.

{
  "size": 0,
  "aggs": {
    "range": {
      "date_range": {
        "time_zone": "Asia/Tokyo",
        "field": "@timestamp",
        "ranges": [
          {
            "from": "now-11d/d",
            "to": "now-4d/d"
          }
        ]
      },
      "aggs": {
        "date": {
          "date_histogram": {
            "field": "@timestamp",
            "calendar_interval": "day",
            "time_zone": "Asia/Tokyo"
          }
        }
      }
    }
  }
}

But I can't get Sunday bucket(31st March) with 0 count.
