However, the Tamemori's name appears in the historical materials published after 1183. In "Gukansho" (Jottings of a Fool), the author wrote that Tamemori served as an envoy for his father Yorimori at the time of leaving the capital; therefore, his death in the battle in the Kurikara Pass might be a writing error.
しかし、その後の史料にもその名が認められ、『愚管抄』では都落ちに際して父・頼盛の使者を務めたと記述されており、倶利伽羅峠での戦死は誤記の可能性もある。
