Taihō (大宝) was a Japanese era name (年号,nengō, "year name") after a late 7th century interruption in the sequence of nengō after Shuchō and before Keiun. This period spanned the years from March 701 through May 704. The reigning emperor was Monmu-tennō (文武天皇).
In 701, also known as Taihō gannen (大宝元年), the new era name Taihō (meaning "Great Treasure") was proclaimed to memorialize the creation of the "great treasure" of codified organization and laws. The new era commenced on the 21st day of the 3rd month of 701.
702 (Taihō 2): A mission to the Tang court, led by Awata no Mahito (粟田真人), embarked on their journey to China, traveling by ship. This was called the "embassy of Taihō" because it was begun during this era.
