Hikami River Tsugu

Date of birth and death unknown. A nobleman in the late Nara period. The second son of Shioyaki Hikami. Also written as Kawatsugi. His mother was Princess Fuwa (the daughter of Emperor Shomu). His wife was Hoitsu, the daughter of Fujiwara Hamanari (Kyo family). His brother was Shigeshimaro, who was involved in the Agata Inukai no Anemme Fuko Incident. In 782 (Enryaku 1), he was appointed as the governor of Inaba, but a member of the Inaba clan, Yamato no Otohito, secretly entered the palace in military gear and was captured, reporting that Kawatsugi was plotting to overthrow the imperial court. As a result, Kawatsugu was arrested in Katsuragikami County, Yamato Province (near Gose City, Nara Prefecture) on charges of treason, and exiled together with his wife to Mishima, Izu Province (Mishima City, Shizuoka Prefecture). His father-in-law, Hamanari, was also stripped of his two official positions as councilor and chamberlain, and 35 others, including Mikata no Omi and Otomo no Yakamochi, were implicated. This is known as the Hikami Kawatsugu Rebellion, and is believed to have been caused by a political conspiracy by the Fujiwara Ceremonial Family over the succession to the throne. Later, in 806 (Daido 1), he was pardoned and restored to the rank of Junior Fifth Rank, and in 809 he became Tenyaku no Kami, and in 812 (Kōnin 3) he was appointed as the governor of Izu.

生没年不詳。奈良後期の貴族。氷上塩焼(しおやき)の二男。河継とも書く。母は不破(ふわ)内親王（聖武(しょうむ)天皇の女）。妻は藤原浜成(はまなり)（京家）の女(むすめ)法壱(ほういつ)。県犬養姉女(あがたいぬかいのあねめ)巫蠱(ふこ)事件に連座した志計志麻呂(しげしまろ)は兄。782年（延暦1）因幡守(いなばのかみ)に任ぜられたが、資人(しじん)の大和乙人(やまとのおとひと)がひそかに兵仗(ひょうじょう)を帯びて宮中に闌入(らんにゅう)して捕らえられ、川継が朝廷転覆を図っていると告げた。このため川継は謀反の罪で大和(やまと)国葛上(かつらぎかみ)郡（奈良県御所(ごせ)市付近）で捕らえられ、妻とともに伊豆国三嶋(みしま)（静岡県三島市）に流された。また義父浜成も参議、侍従の二官を奪われ、さらに三方(みかた)王、大伴家持(おおとものやかもち)ら35人が連座した。これを氷上川継の乱といい、皇位継承に絡む藤原式家の政治的陰謀によって起こったものとみられている。その後、806年（大同1）に罪を許されて従(じゅ)五位下に復し、809年には典薬頭(てんやくのかみ)となり、812年（弘仁3）には伊豆守に任ぜられた。
