蝦夷方言藻汐草

Toyta sisam separates the documented farming verb from the Wajin ethnonym. Tamura illustrates the plural toytapa sisam utar as Wajin farmers, and Hirayama analyzes this historical entry with the same components. The complete toyta sisam phrase has no corpus match here. The source’s final モ permits toyta sisamo as a closer literal comparison; its relation to modern final m remains uncertain. The Japanese 百姓 is broader than a phrase specifically describing Wajin farmers, and the evidence does not establish an identical social category.
