With foreigners increasingly living in Fukushima, especially trainees and students from Asia, the National Governors Association issued a joint declaration to promote a multicultural coexistence society. The declaration rejects discrimination based on unfounded information and calls for calm, evidence-based discussion that ensures opportunities for both Japanese and foreign residents, while taking strict action against illegal acts and misuse of systems. In Fukushima, foreigners numbered 19,650 as of last December, nearly double 9,963 in 2014, and have exceeded 1% of the prefectural population since 2023; foreign workers stood at 13,710 as of last October across manufacturing, construction, wholesale/retail, and hospitality. To address language and lifestyle differences, multilingual support should be strengthened, including translation apps and volunteer interpreters. Expanding venues for interaction between foreigners and locals, encouraging participation in local festivals, can deepen mutual understanding and make diverse cultures a regional asset for the future.
