In this era of san-pitsu, Saicho should be listed as an especially excellent calligrapher as well, and "shinkan-kokuchoshoninshi" (a poem of regretting the death of Saicho, written by the emperor himself) that Emperor Saga wrote regretting the death of Saicho in the sosho-tai (cursive style writing) style remains.
また、この三筆の時代に特筆すべき能書として最澄がおり、嵯峨天皇の宸翰に最澄の入滅をなげき悲しんだ草書体の『宸翰哭澄上人詩』（こくちょうしょうにんし）がある。
