Dry stone walling techniques have been succeeded thorough centuries in each village, but now, the phenomenon of depopulation is bringing this traditional system into difficult, and dry stone walling techniques are faced with a problem of disappearing. So this study researched following two things. 1) To present the maintenance condition of stone walls and the succession of dry stone walling techniques in Tokushima Pref. 2) To make clear the differences and common techniques. In conclusion, the maintenances of stone walls are insufficient in almost places of Tokushima Pref. and we can say that the primal techniques are common in the whole prefecture.
