Age of Empires Series Wiki

Artillery that fires an exploding shell at buildings or ships.
—In-game description

The Morutaru (Japanese: モルタル, katakana for "mortar") is an artillery unit in Age of Empires III: The Asian Dynasties that is unique to the Japanese and can be trained at the Castle once the Industrial Age is reached, and by Shogun Tokugawa. It is the Japanese version of the Mortar.


Compared with the Mortar, Morutaru are slightly cheaper and take up 1 less population per unit. They also cause less siege damage, have less hit points and move slower than Mortars when in Limber mode, but faster when in Bombard mode. Just like Mortars, they are extremely potent long range siege and anti-warship units, but are unable to attack anything other than buildings and ships.

Much like Flaming Arrows, they have almost no set-up time and can hit-and-run ships, or snipe buildings and retreat quickly.

With the Morutaru Range card, Morutaru acquire an amazing 44 range (and 48 LOS). The only Mortar that beats its range is the Portuguese one, with 48 range and 52 LOS.

As Morutaru are unique to the Japanese, only their cards and other civilizations' TEAM cards are shown in the following tables:


In the late sixteenth century, when armies of Japan returned from their military campaigns on the Korean peninsula, they brought with them many lessons in siege acquired from their sophisticated Korean enemy. Unfortunately, use of the mortar, a military art that the Koreans had perfected, was something in which the Japanese did not appear interested. They continued their usual practice of importing European cannons. However, in 1639 the Japanese played host to visiting Dutch advisors who demonstrated a mortar for the Shogun and his representatives. The demonstration caused an uproar even though not one shell fired hit its intended target.
