Missions for Discovery
Switch modes and explore with guiding questions to read the landscape.
Climb to Kanazawa Castle
Why did the Maeda clan choose this location for their castle? Look at the rivers and plateau to understand their strategic thinking.
Walk Between Two Rivers
The Sai and Asano rivers define Kanazawa. How did these rivers shape the city layout and daily life?
Find the Kodatsuno Plateau
Can you identify the plateau where temples and shrines were strategically placed as a defensive line?
Trace the Tatsumi Irrigation
The Tatsumi Canal brought water to Kenrokuen. From the terrain, can you guess its route from the mountains?
Discovery Guide
A 3D terrain model is not only for viewing, but for reading. Use these tips to discover the story of the land.
Reveal with Light
Set the sun to morning or evening to create long shadows that highlight subtle landforms—similar to how archaeologists detect sites in aerial imagery.
Read the Terrain
River terraces, alluvial fans, and plateau edges are key clues that shaped where people settled and built defenses.
Walk in Explorer Mode
Check what is visible from where you stand: "Can I see Mt. Utatsu?" "What appears after crossing the river?" Use lines of sight as evidence.
Survey in Giant Mode
From above, focus on how the two rivers create natural boundaries. Look for plateau edges and the temple district placements.
