Actualment, al Japó, s’accepten els immigrants que contribueixen a reduir el dèficit de personal del sector de la infermeria. Sono, en el seu article, defensa que Japó hauria de crear un marc jurídic que mantingués l’estatus d’aquests treballadors com a immigrants i que no n’autoritzés la naturalització.
While Japan has to let immigrants come to help ease the labor difficulties facing the nursing care sector, Sono says in her Sankei column, Japan needs to create a legal framework that strictly maintains the status of these workers as immigrants, and does not permit naturalization.
