How Japan is using 3D tech and traditional craft to protect cultural heritage from climate risks

Preserving Japan’s Heritage One Scan at a Time

Why the 3D‑Scanning Squad Is Gritting Its Teeth

Japan’s ancient temples and shrines aren’t just beautiful—they’re living history pieces that keep fighting weather, earthquakes, and humidity every day. That’s where high‑tech meets old‑school arts.

• Climate Change – Rising temperatures and unpredictable storms could soften stone joints faster than a bad hair day.
• Earthquakes – A quake‑proof shrine is like a superhero cape for your favorite building.
• Humidity – Moisture can turn a masterpiece from “wow” to “whoa, what happened?”

Meet the Eiheiji Temple: A Case Study

We’re starting in Fukui Prefecture’s proud Eiheiji temple, where artisans and tech geeks work hand‑in‑hand. Using laser‑based 3D scanners, every carved pillar, painted roof, and ancient mural is captured in ultra‑high detail. Think of it as a digital Godzilla‑style preservation plan.

How It Grows

Once scanned, the temple’s data is fed into a “digital twin.” This twin can:

1. Spot damage before it becomes “oh no!”
2. Guide craftsmen on exactly which screws to tighten to save an entire boulder.
3. Help museum curators create VR tours for future explorers—no need to hike out of the rain, too.

Future‑Proofing Our Past

Imagine retiring from the battlefield of conservation and just sipping tea, watching artisans repair a digital replica with pinpoint muscle memory. That’s the dream—protected heritage, one scan at a time.

In Japan’s Fukui region, the historic Eiheiji temple is being digitally preserved with advanced 3D laser scanning. The project, led by specialists from T&I 3D and Shimizu Corporation, creates a “Digital Twin” — an exact virtual replica that captures hidden structural details, aiding in restoration and resilience planning. Rising humidity, landslides, and earthquakes are growing threats to centuries-old architecture.
At Kanazawa Castle, craftsmen are restoring quake-damaged walls using traditional Arakabe plaster, made from rice straw and soil. Experts say combining digital precision with traditional techniques offers a powerful solution.

For the Eiheiji monks, the project is also a chance to share their spiritual heritage with the world.
