You can then invade, get the Shinobi in place and then move on. As Sun Tzu said: "...it's a matter of organisation".
Fielding teppo units can be difficult and of course they're of most use defensively. Their weapons cause fear to the enemy and are good at penetrating armour. The downside is that they cannot fire in rain so you cannot rely on them entirely. When developing provinces for teppo, I tend to focus on morale and armour upgrades as much as possible. Weapon upgrades won't be of much use in most cases.
As far as tactics go I tend to take a "pike and musket" approach and I back up teppo units with YS units. The trick to any missile unit is not to order them to attack, but instead to position them correctly in a good vantage point over the enemy. It's then a matter of turning on/off fire at will and letting them find their own targets. If you manually target eneies you'll find that your line will go out of formation and the whole thing will turn into a mess. I tend to only manually target if a particular unit is closing in fast and I want to hit it with a volley before it makes contact. In such a case I would turn off skirmish mode, let the volley go off then turn off fire at will and then bring the pike line forward through the ranks of the teppo line to meet the enemy. This leaves the teppo safely behind. It's a very good idea to use YS because if the teppo do decide to rout they won't take the lesser quality YA with them.
