For the Village of Treasures event I spend about 40k koban and did the event slowly, achieving the Monoyoshi prize a few days before the end and making the best use of the free passes. I also sent my teams to expeditions and in the end I finished the event with the same amount of koban i had when I started (around 35~40k).

For the Regiment Battle I did it a little bit faster and spend around 50k koban. This event I started with about 65k and finished with 55k koban, since I also did lots of expeditions. However, if the event is Regiment battle-like it's more difficult to send your teams to expeditions since it's possible you'll need more than one team for the battles, so you won't be able to send all of them to do expeditions.

Based on how much I've spent in past events you'll be fine with about 50k koban, if you also manage to send teams to expeditions during the event you can even have a little bit less than that. If you really want to finish the event faster you'll need a little more. That is, if they don't make the passes cost more (I doubt it, though)
