Honmon Kaidan no Daigohonzon has evidences of tools in the Kamakura period, however, it was possibly made in later years since the Nichiren Sect while Nichiren was alive wasn't able to afford the cost, the flower stamp was different from Nichiren's, and it was very similar to Zenshi juyo mandala (Mandala given by Zenshi), and so on.
本門戒壇の大御本尊については鎌倉時代の工具の痕跡があるが、日蓮が生きていた時代の日蓮宗の財力では製作不能といった状況証拠や花押が日蓮の物と違う、禅師授与漫荼羅との酷似等の理由で、後世の偽作ではないかといわれている。
