Construct as many trade ships as you can and send them to occupy the trading zones around you. With a firm base on Kyushu you can take a short break to build your economy and forces. Move your army further towards the castle of Hyuga, dealing with any Ito (remnants from the previous army or new troops) as you encounter them. Move as far as possible towards Hyuga’s castle town. Don’t forget to use your generals to mob up enemy routers so you don’t have to fight them again. The area provides some nice hills you can use to defend so you should be able to defeat them. If you don’t find any Ito they will probably attack you during their turn. If you encounter an Ito army, attack it and take it out. You will suffer casualties from attrition but in my opinion it’s worth it because you can get to the Ito city sooner. With your army, march north into the Ito province. Send your newly recruited Bow Kobaya to capture the trade point directly south of your port. Build a trading port in Satsuma to continue towards the recruitment of trade ships. Train another unit of Yari Ashigaru in Osumi to help stabilize the province. Take both the daimyo and general with you, but leave one unit of Yari Ashigaru behind and exempt the city from taxes to keep the populace under control. Osumi should be stable enough to move your army on. The first big battle you’ll fight against the Ito when you attack them. This will complete the mission “Establish a Foothold” which gives you one extra recruitment slot in all provinces for four turns. With numbers and topography on your side you can beat them with minimal casualties before capturing the castle. If you then deploy on the right-hand side of the map you’ll be able to cut of the re-inforcements before they can join the castle defenders. To minimize your casualties, you should assault immediately. As you’ll see, there’s a small garrison and a bigger army nearby. Send your daimyo from your capital to join your army, then march towards the first Ito town and besiege it. After that this guide contains more general directions for the rest of the campaign.
When you’ve completed those you’ll be on your way to controlling the trade points around the south coast, you’ll have eliminated the Ito, and you’ll have started recruiting the Katana Samurai backbone of your armies. The first six turns are described on a turn-by-turn basis. Below you’ll find a walkthrough to help you make the most from their huge potential. In the far south of Japan, the Shimazu have an excellent starting position: quick access to the trade points, an easily defensible island as home region and some nice clan bonuses they’re a popular choice among Shogun 2 players.
