It's worth pointing out here, though, is that 2xyari ashigaru+Market might be a better option than Sake Den, assuming this is just a Fort province (ie, single building slot), since the Market produces more than twice as much money as the Sake Den, and still more than a Gambling Den.

I forget the base upkeep on Yari Ashigaru, but I think it's something like 20 each?, reduced by a few % here and there.
