Assuming you can complete all 10 waves, that's 150 otoshidama for you up front, multiplying it by the map bonus of x2 gives you 300 in total.

That means you'll need an approximated total of 167 tickets to get to Hiza, 120 of which you are given for free if you take advantage of the daily refills. That leaves 47 more that you have to buy, which translates roughly into 16000 koban.
