No inscription, temple record or contemporary chronicle names the sculptor, workshop or foundry responsible for casting the 1252 bronze, unlike a number of later Japanese Buddhist bronzes whose makers are documented.
What would resolve this A surviving Kamakura-period temple record, a foundry mark recovered from inside the hollow bronze during conservation work, or a documentary source not yet examined naming the casting workshop.
