The is the treasure house of Tōdai-ji Temple in Nara, Japan. The building is in the azekura (log-cabin) style with a raised floor. It lies to the northwest of the Great Buddha Hall. The Shōsō-in houses artifacts connected to Emperor Shōmu (聖武天皇)(701–756) and Empress Kōmyō (光明皇后)(701–760), as well as arts and crafts of the Tempyō (天平) era of Japanese history. History The construction of the Tōdai-ji Buddhist temple complex was ordained by Emperor Shōmu as part of a national project of Buddhist temple construction. During the Tempyō period, the years during which Emperor Shōmu reigned, multiple disasters struck Japan as well as political uproar and epidemics. Because of these reasons Emperor Shōmu launched a project of provincial temples. The Tōdai-ji was appointed as the head temple of these provincial temples. Emperor Shōmu was a strong supporter of Buddhism and he thought it would strengthen his central authority as well. The origin of Tōdai-ji's Shōsō-in repository itself dates back to 756, when Empress Kōmyō dedicated over 600 items to the Great Buddha at Tōdai-ji to express her love for her lost husband, Emperor Shōmu, who died 49 days earlier. Her donation was made over five times across several years, then stored at the Shōsō-in. During the Heian period, a large number of treasures, consisting of items and instruments used in important Buddhist services were transferred from a different warehouse called the Kensakuin to the Tōdai-ji. After the Meiji Restoration, it came under the administration of the national government, and since World War II has been under the administration of the Imperial Household Agency. It is on the UNESCO register of World Heritage Sites as one of the Historic Monuments of Ancient Nara. It is also a National Treasure of Japan. Building The building is in the Azekura Zukuri log-cabin style, with a floor raised to about 2.5 m . This is an architectural style that was mainly used for the construction of granaries and storehouses. Some distinctive features of this building style are the triangular, wooden beams that come together in the corners, as well as the fact that it was assembled without using any bolts nor nails. This could be slightly surprising for its height of 14 m, width of 33 m and depth of about 9.3 m. However, it was a logical and smart step. As a result of assembling the storehouse without bolts or nails, the structure became
