The Japanese are an East Asian civilization in Age of Empires II. They are an infantry-based civilization, with their infantry possessing the fastest attack speed in the game. They are the descendants of the Yamato civilization, which inhabited the same island. The Japanese civilization is based on Feudal Japan which was dominated by the powerful regional families (daimyō) and the military rule of warlords (shōgun) from 1185 to 1868. The Samurai were the elite warrior class in Japanese society and required dozens of years of training. The Samurai were armed with a Katana, an extra-sharp, thin bladed longsword, a Wakizashi, a shorter version of the Katana, and sometimes a Tantō. These soldiers served the lord and fought for them based on the strict Bushido honor code. To reflect their high rank and prestige of the Japanese warrior class and their association with the ninja, a covert agent, Japanese infantry attack faster.
Japan is an island nation sea-reliant for most of its history, and as a result, the Japanese have extensive knowledge in maritime economy and warfare. To represent this, their Fishing Ships have double hit points and work more efficiently when advancing through the Ages, and the Japanese team's Galley line have a longer Line of Sight. Japan also possesses a number of volcanoes which create fertile lands for cultivation and ores for mining. To reflect this, the Japanese build Mills, Lumber Camps, and Mining Camps at a cheaper cost.
Throughout its medieval history, Japan was in constant conflicts of clan lords who constructed a large number of fortifications; each had many arrowslits (or yasama) to repel attackers. This is represented by the technology, Yasama, which increases the number of arrows shot by towers. Also, during Sengoku Jidai (or the Warring States period), the Japanese came into contact with the Portuguese and the Dutch, with whom the Japanese traded goods for firearms and modern siege technology. This is reflected by Kataparuto ("catapult" written in katakana to represent the European origin) that allows Trebuchets to pack, unpack, and fire faster.
The Japanese are an infantry civilization and command the strongest infantry of all civilizations with all technologies and upgrades available plus a speed boost for their attacks which results in a very high damage output. The Japanese also have superb archers (including Cavalry Archers) which they can also fully upgrade. Only their cavalry is weak and their siege weapons are underwhelming as well but their Trebuchets greatly benefit from Kataparuto meaning their sieging is still fairly effective. Their navy is excellent, only lacking the Heavy Demolition Ship, but with longer-sighted Galleons and all other improvements at their disposal. Their Monks are very good as well, only lacking Heresy. Their defensive structures and economy are below average, however.
