If you want to obtain Ookanehira before the event ends, you're looking to average about 3575 otoshidama a day... so you'll definitely have to purchase more passes using koban, unless you're constantly using those double boxes.

I only need two teams for expert map, so if you can - send your spare teams to farm koban! It adds up quite quickly. Just before Kogarasumaru's event, I farmed koban like crazy. I started with 35k, and now I'm on 88k even though I spent koban for Koga's event too. So definitely farm those expeditions if you can.
