The amount of waste generated by the disaster from the Great East Japan Earthquake was estimated to be about 25 million ton, of which about 80% was composed of wood waste. To utilize such woods efficiently, 21 samples of tsunami deteriorated woods were collected in Otsuchi town, Iwate Pref. and they were characterized by anatomical observation, moisture content, ash content, and major and minor element analyses. The moisture content was less than 16%(wet basis) except 1 sample. Ash content was almost close to that of virgin samples, whereas one sample showed 1.5%. Chlorine and sodium contents tended to be higher for the deteriorated woods.
