Age of Empires Series Wiki

Enables Sabotage ability for Japanese Monks. Use it to cause great damage to buildings.
—In-game description

Kayakujutsu is a technology in Age of Empires III: The Asian Dynasties that is unique to the Japanese and can be researched at the Monastery once the Industrial Age is reached. Once researched, it allows the Sohei Archer to use the Sabotage ability, which is similar to a Petard's attack but has greater range (0-16), deals less damage (1,500), can be used against ships, and does not kill the user.


  • The technology shares the same icon with the Sohei Archer Sabotage ability it unlocks.
