This value is equal to the title of the x-axis, so you can use the xAxis.title.text property to set this text, and if you don't want it to be visible in the graph below the axis, you can set xAxis.title.enabled to false:

xAxis: {
  title: {
    text: 'カスタムテキスト',
    enabled: false // to hide on chart
  }
}

Another way for other chart types that don't have axes, such as pie charts, is to use the exporting.csv.columnHeaderFormatter() function:

exporting: {
  csv: {
    columnHeaderFormatter: function(item, key) {
      if (!item || item instanceof Highcharts.Axis) {
        return 'カスタムテキスト'
      } else {
        return item.name;
      }
    }
  }
}
