Imagawa Ujiteru

Who They Were

Imagawa Ujiteru (今川氏輝, いまがわ うじてる) was a Japanese daimyō (大名, だいみょう — a great territorial lord) of the Sengoku period who ruled the Imagawa clan from Suruga Province. He was born in 1513, the son of Imagawa Ujichika (今川氏親) and Jukei-ni (寿桂尼, d. 1568). His childhood name was Ryuomaru (竜王丸). He held the position of daimyō and was a samurai by occupation, living during the Muromachi period (1336–1573), in the tenth year of the Eishō era (永正).

Life and Career

Ujiteru was born in Suruga Province in 1513, the eldest son of Imagawa Ujichika. His mother, Jukei-ni, would outlive him by more than three decades, dying in 1568. He was a brother of Imagawa Yoshimoto (今川義元), who would eventually succeed to the headship of the clan.

Ujiteru's reign lasted ten years, from 1513 to 1536. During that decade, no uprising was recorded against his rule. That internal calm laid the foundation for the later successful reign of Yoshimoto and for the Imagawa clan's broader fortunes. The absence of recorded rebellion is the central fact of his tenure as daimyō.

On April 7, 1536, Ujiteru died. His death came after an illness. It triggered a struggle for Imagawa power known as the Hanakura Conflict (花倉の乱, はなくらのらん), fought between his elder half-brother, Genkō Etan (玄広恵探), and his younger brother, Yoshimoto. Yoshimoto emerged from the conflict as the new head of the Imagawa clan.

Why They Matter

Ujiteru's importance lies less in what he did than in what his death set in motion. A decade of quiet rule ended abruptly in 1536, and the succession crisis that followed — the Hanakura Conflict — reshaped the Imagawa clan's leadership at a critical moment in the Sengoku period.

The conflict pitted Genkō Etan, Ujiteru's elder half-brother, against Imagawa Yoshimoto, his younger brother. Yoshimoto's victory placed him at the head of the clan, and it was under Yoshimoto that the Imagawa would go on to their most celebrated period of power. Ujiteru's reign, free of recorded internal revolt, is the groundwork on which that later success rested.

His mother, Jukei-ni, remained a presence in Imagawa affairs long after her son's death, living until 1568. The family network Ujiteru belonged to — father Ujichika, mother Jukei-ni, brother Yoshimoto — formed the core of the Imagawa leadership through the middle of the sixteenth century.

The Name in Japanese

The name is written 今川氏輝. In kana it reads いまがわ うじてる. In romaji it is Imagawa Ujiteru.

Breaking it down character by character:

• 今 (いま, ima) — "now," "the present." In this name it forms the first element of the clan surname.
• 川 (がわ, gawa) — "river." Combined with 今, it gives the surname 今川, Imagawa, literally "present river." The reading shifts from kawa to gawa because of the preceding element, a common sound change in Japanese compounds.
• 氏 (うじ, uji) — "clan," "family," "lineage." This kanji is a standard element in samurai names, signalling membership in a family line. Here it begins the given name.
• 輝 (てる, teru) — "to shine," "radiance," "brilliance." It closes the given name, so that 氏輝 reads Ujiteru.

The surname 今川 identifies the clan; the given name 氏輝 marks the individual. Note that the kanji 氏, read uji, is the same character used generally for "clan" in Japanese historical writing — a fitting element for a daimyō's name.

Legacy

Imagawa Ujiteru is remembered chiefly through two threads: the peaceful decade of his rule and the succession conflict that followed his death. The Hanakura Conflict, sparked by his passing in 1536, ended with Imagawa Yoshimoto as clan head. Yoshimoto's rise — and the Imagawa clan's later prominence — rested on the stability Ujiteru had maintained.

His mother, Jukei-ni, survived him by thirty-two years, remaining part of the Imagawa story until 1568. His father, Imagawa Ujichika, preceded him as clan leader. The line from Ujichika through Ujiteru to Yoshimoto traces the Imagawa clan's leadership across the Sengoku period.

A temple connection survives in the record: Rinzai-ji Temple is named after him. That association keeps his name attached to a physical site, even as the political legacy of his short reign passed into the hands of his younger brother.
