Soon after the 2011 Tōhoku earthquake and tsunami, Keene retired from Columbia and moved to Japan with the intention of living out the remainder of his life there. He acquired Japanese citizenship, adopting the legal name Kīn Donarudo (キーン ドナルド). This required him to relinquish his American citizenship, as Japan does not permit dual citizenship.[3]
