Disclaimer: If it's actually hardcoded, just change it to '2012/3/9'.

Parse the date, add 5 days, and convert it to a string again:

var d = '2012/3/4';
var parts = d.split('/');
var date = new Date(+parts[0], +parts[1] - 1, +parts[2]);

date.setDate(date.getDate() + 5);

var result = date.getFullYear() + '/' + (date.getMonth() + 1) + '/' + date.getDate();

Here's a demo.

And here it is put in your code:

var d = '2012/3/4';
var parts = d.split('/');
var date = new Date(+parts[0], +parts[1] - 1, +parts[2]);

date.setDate(date.getDate() + 5);

var result = date.getFullYear() + '/' + (date.getMonth() + 1) + '/' + date.getDate();

var dates = $( "#from, #to" ).datepicker({
    dateFormat: 'yy/mm/dd',
    changeMonth: true,
    minDate: result,
    onSelect: function() { 
       var d1=new Date($('#from').val());
       var d2=new Date($('#to').val());
       $('#quantity').val((Math.ceil((d2-d1)/86400000)));
    }
});
