| AD 746 | Shoku Nihongi (Continued Chronicles of Japan) | More than 1,100 Bohai people and Tieli people come to court seeking asylum; they are housed in Dewa Province and then sent back with clothing and provisions. |
| AD 775 | Shoku Nihongi (Continued Chronicles of Japan) | Dewa Province, since the Emishi remnants have not been pacified for three years, asks for 996 garrison soldiers and the relocation of the provincial administration; soldiers are sent. |
| AD 786 | Shoku Nihongi (Continued Chronicles of Japan) | The Dewa Province reports that 65 persons, including the Bohai envoy Yi Wontae, drifted ashore in one ship, and that twelve of them were seized and plundered by the Emishi. |
| AD 875 | Nihon Sandai Jitsuroku | Dewa province reports that the Watarishima chieftain Kōteki rebelled with eighty naval ships, killing 21 people and plundering in Akita and Akumi districts. By imperial edict, the local magistrate (bokusai) is to subdue them. |
| AD 878 | Nihon Sandai Jitsuroku | On the twenty-ninth day of the third month, the governor of Dewa, Fujiwara no Okiyo, reports by post horse that the barbarians (ifu) rebelled and on the fifteenth day of the third month burned Tsuiden castle, the district office and nearby houses (the Genkei War). By imperial edict, districts are chosen to block the key points, and if that is insufficient, aid is requested from the six provinces of Mutsu. |
| AD 878 | Nihon Sandai Jitsuroku | The governor of Dewa reports that the bandits grow fiercer: six hundred men were sent to guard the Yadai pass, but at Yakiyama they met more than a thousand enemies, over five hundred fled, and the villages around the castle were burned. By imperial edict, one thousand soldiers each are sent from Kōzuke and Shimotsuke, and Mutsu is to send aid as well. |
| AD 878 | Nihon Sandai Jitsuroku | On the fifth day of the fifth month, the governor of Mutsu, Minamoto no Yasushi, reports that he sent 2,000 men to Dewa and was asked for 500 more; because the barbarians of his own province are restless, he requests 2,000 reinforcements. By imperial edict, out of concern about wasting provisions, he is instead to reduce labor as an expedient measure. |
| AD 878 | Nihon Sandai Jitsuroku | On the tenth day of the seventh month, Fujiwara no Yasunori, acting governor of Dewa and Right Middle Secretary, arrives and draws up military plans: about 600 soldiers from Kōzuke are stationed south of the Tsuiden River to block the northern enemy, and he reports separately twelve enemy villages and three villages that have submitted. |
| AD 878 | Nihon Sandai Jitsuroku | On the twelfth day of the tenth month, Dewa province reports that on the twenty-ninth day of the eighth month more than three hundred rebels came below the castle and asked to surrender. Sakanoue no Yoshikage, acting vice-governor of Mutsu, arrives with 2,000 soldiers; the Chinju-shōgun Ono no Harukaze and 470 others reach the north of Tsuiei (the Akita camp). |
| AD 879 | Nihon Sandai Jitsuroku | On the second day of the third month a memorial is submitted: on the thirteenth day of the first month an attack was to be launched by imperial command, but with 1,800-odd troops (800 each from Kōzuke and Shimotsuke, 200 from Mutsu) it is difficult to advance or retreat. The rebels submitted a petition of more than ten articles; as their grievances have reason, the penalties are relaxed and they are pacified. |
| AD 884 | Nihon Sandai Jitsuroku | On the twenty-ninth day of the ninth month, Dewa reports that on the twenty-sixth day of the sixth month thunder and rain darkened Tsuiden castle and twenty-three stone arrowheads fell; on the second day of the seventh month they fell also on the seashore of Akumi district. The Onyōryō divines a warning of military levies or epidemic. |
