However, the more cases of excavation of bronze wares there were naturally along with increased excavations of ruins, the more situations where dohoko and doken were found in 'the dotaku cultural area' and where dotaku were discovered in 'the dohoko cultural area' (well-known example: the Yoshinogari Ruins) there were, which proved the hypothesis was not true as it was less and less often discussed.
しかし、発掘される遺跡の増加に伴い当然のことながら青銅器の出土例も増え、「銅鐸文化圏」の地域で銅矛や銅剣が、「銅矛文化圏」内で銅鐸が出土するといったこと（特に有名な例が吉野ヶ里での出土）が多くなり、この仮説は成り立たなくなり次第に論じられる事は少なくなった。
