Japanese technology tree
The Japanese technology tree index links recorded Age of Empires III units, buildings and research to their individual reference pages. It emphasizes entries whose game data directly identifies this faction and is not a complete reconstruction of every shared option in the in-game tree; check unit and technology pages for additional civilization access.

Civilization roster and research
The lists are grouped into units, buildings and technologies, then organized by the Age recorded in the game data. Shared options can appear in more than one civilization index; inclusion does not mean an item is unique. Follow an entry to check its cost, production or research site, prerequisites, counters and version band. A Home City Card, map alliance or scenario rule may change access, so this list is not a fixed build order.
Scope and availability
Scope: Age of Empires III civilization content. This index reflects matching entries in the saved game-fact records; each linked page gives its own version, Age and access conditions.
How to read the tree
Use the tree when planning an Age-up, Home City deck or response to an opponent. Find the unit line or upgrade that answers the immediate matchup, then check its entry for exact values and access rules. Map, mode, shipments, patch and edition determine which recorded options are useful in a particular match.
