The last land on which the Japanese will be Your enemy. You'll be able to once and for all show them who's the boss.
The beginning is like usual, building up in a specific order - build the most needed buildings first, and later build the rest. Use the area in the green figure for the fields since that's where the most fertile land is. The hill (blue figure) is the best area for the most impressive buildings, that area is the most impressive and increases impressiveness. Place two walls on the land pointed out by the red lines. Playing as the good god You might need more space, so move the walls further out.
You can't complain about not enough wood, but You can't say the same about ore. The only near mine (green dot) might not give enough ore, so quickly build a 'smelter' so that You'll have more ore.
Place Your creature in the blue dot since that's the path the enemy platoons will most often use to get to Your city. His battle abilities will stop the enemy before they can start devastating Your capital.
If You wish to conquer the land by force, take over the village in the order pointed out on the picture. The first villages (1's) shouldn't be guarded by the enemy. You'll take them over without much trouble. City number two is surrounded by walls and bigger platoons will be stationed in it. Send and carefully steer Your creature, so that he'll significantly weaken the enemy forces (especially archer platoons). After that, take the city over with Your army. Village four also shouldn't be such a pain in the neck. For the city on the hill (four), You should destroy the enemy's archers on the walls with Your creature and go in with a large army. Send out one platoon to capture the 'town hall', and another to attack enemy platoons. The last standing city You should attack with all Your remaining forces (best if around 200-250 troops) and with Your creature. The platoons of archers and catapults located there, try to force out by making them follow You, and then destroy them (with Your creature) one by one so that You can later on attack with a big advantage.
Once You have taken over a city and Your influence line shows up, You don't have to keep Your troops there. When the enemy will want to take it over, wait for them to cross the green line and bomb them with Your fire miracle. This is 100% successful.
