Kura (倉 or 蔵) are traditional Japanese storehouses. They are commonly durable buildings built from timber, stone or clay used to safely store valuable commodities.
Kura in rural communities are normally of simpler construction and used for storing grain or rice. Those in towns are more elaborate, with a structural timber frame covered in a fireproof, clay outer coating. Early religious kura were built in a "log cabin" style, whilst those used later to store gunpowder were constructed from stone.
Earthen kura, dozō have evolved a particular set of construction techniques in order to make them relatively fireproof.[1]
