Yumishi

Overall strategy
While they seem to be inferior in many ways to conventional Ronin Archers, do not be fast to dismiss Yumishi archers. They may not be as hard-hitting nor as fast to train and move around as Ronin Archers, but when it comes to combat, they have several advantages The first, clearly, is their ability to cloak themselves like the Emishi Kondei. This, coupled with their additional hitpoints and armour, as marginally higher as they may be compared to normal Ronin, can actually mean a lot as they are better at hit and run attacks, having higher survivability, thus making them ideal units for skirmishing and ambushing, if backed up by other units.

Although they have good range, their LOS is terrible -- so using Spies against isolated pockets of these units is usually a good idea if you are playing against the Japanese civ, provided you are capable of spotting these units early on.
