Create as much "Green Giant Generators" as you can. Conquer all except the LAST prefecture, instead of conquer it, pass turn until you get to day number 400. You will have the most powerful army, 25 Green Giants. When you complete all prefectures, 4 islands will show on the map. You can't win against them with the "Warriors w/Sword". The only way is to create an army of Green Giants (25) for each available bridge. It takes a lot or you can use the "WALL Perk", Snipers (10) and Warriors(15) to block 2 bridges until you conquer all islands with your GREEN TEAM . So, great game, simple, but hard. Keep Trying! GG

I can't beat this game, its pretty hard. I need some help to increase my hability. Even after defeating everything, after the islands, all went to shit.

Just create a 25-green giant army before the islands appear, and use speed. It's be enough to oliterate them, with full samurai army. (You have the whole country to fund you)
