The Utsunomiya are a Shimotsuke house of the Fujiwara, shrine lords and warriors at once: their seat, Utsunomiya, grew round the Futarayama shrine, the Ichinomiya of the province, and their head is its senior priest as well as a houseman of Kamakura (recalled).
They are one of the three great houses of Shimotsuke with the Oyama and the Ashikaga. The marriage link to Hōjō Tokimasa (Yoritsuna's wife) puts them on the Hōjō side of any quarrel, and so, in 1205, in danger when Tokimasa's own circle accuses Hatakeyama Shigetada and others (recalled). Yoritsuna is also a poet in Fujiwara no Teika's circle, which gives the Utsunomiya a foot in Kyoto's literary world; that is later and is only noted here.
Who he is
- Name
- not pinned between Utsunomiya Naritsuna and his son Yoritsuna
- Title
- Head of the Utsunomiya house; hereditary head (zasu) of the Futarayama shrine, the Ichinomiya of Shimotsuke (recalled)
- Since
- not pinned
- Born
- Yoritsuna is recalled as b. 1178; Naritsuna's dates are not known to me
- Family
- Yoritsuna (later the monk Renshō, Ogura Nyūdō) was the son of Utsunomiya Naritsuna and married a daughter of Hōjō Tokimasa; his daughter later married Fujiwara no Teika's son Tameie (English Wikipedia: Utsunomiya Yoritsuna). So in 1200 the Utsunomiya are the Hōjō's in-laws.
- Confidence
- low
English Wikipedia (Utsunomiya Yoritsuna) for the parentage and the Hōjō marriage; everything else is recalled. The English pages on the clan and on Tomotsuna were not found.

By descent; the housemen's grants.
Allies and rivals
Tied by marriage to the Hōjō. Shimotsuke neighbours: Oyama (stronger as constable), Ashikaga. No quarrel is known for the winter.

Quiet; no event is dated for them in the winter.

Military
Utsunomiya housemen and the shrine's guard; no numbers.
Threats
- The Oyama as constable over them
- Court claims on the shrine's estates
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- Genkyū 2 (1205, recalled)Yoritsuna is accused of plotting and takes the tonsure under the name Renshō; the Utsunomiya survive.Depends on: Hōjō Tokimasa's last year of power Stopped by: Tokimasa's fall in the seventh month
Where the sources disagree
- The heads' names for 1 January 1200 are not pinned: Naritsuna is the father of Yoritsuna on the English page, but we could not see which of them led the house that winter.
Evidence: One English page on Yoritsuna; the rest recalled.
On the map: Home district only.
