Wood quality and material integrity of wildfire-exposed Cryptomeria japonica evaluated by mechanical grading and multi-scale characterization
This study demonstrates that Japanese cedar logs recovered three months after the 2025 Ofunato wildfire retain substantial internal material integrity and meet structural grading requirements despite severe charring, indicating that mechanical grading is more reliable than visual assessment for salvage decisions, although rapid processing is critical due to bark loss and further durability testing is needed before final product use.
