This article explains how the US westward expansion influenced and stimulated Japanese migration to Brazil. Emerging in the nineteenth century as expanding powers in East Asia and Latin America, respectively, both Meiji Japan and post-independence Brazil looked to the US westward expansion as a central reference for their own processes of settler colonialism. The convergence of Japan and Brazil in their imitation of US settler colonialism eventually brought the two sides together at the turn of the twentieth century to negotiate for the start of Japanese migration to Brazil. This article challenges the current understanding of Japanese migration to Brazil, conventionally regarded as a topic of Latin American ethnic studies, by placing it in the context of settler colonialism in both Japanese and Brazilian histories. The study also explores the shared experiences of East Asia and Latin America as they felt the global impact of the American westward expansion.

大融合：美国边境和日本移民巴西的起源

本文解释了美国向西扩张如何影响和刺激日本移民到巴西。19 世纪，作为分别在东亚和拉丁美洲扩张的大国，明治日本和独立后的巴西都将美国向西扩张视为他们自己的定居者殖民主义进程的核心参考。日本和巴西在模仿美国定居者殖民主义方面的趋同，最终使双方在 20 世纪之交就开始向巴西移民进行谈判。本文通过将其置于日本和巴西历史上的定居者殖民主义背景下，挑战当前对日本移民巴西的理解，该理解传统上被视为拉丁美洲民族研究的主题。
