The programme is being introduced against a backdrop of growing strain on the education system, including a shortage of teachers that has reportedly left around 10,000 children without the Japanese-language instruction they need. The ministry's survey, carried out through local boards of education, examined how schools are dealing with students unable to hold everyday conversations in Japanese. Public schools with at least one such student made up 39% of the total, or 12,668 schools. Another 4,329 schools, roughly 13%, had five or more students needing support. In 28 schools, the number exceeded 100. The figures also showed the issue spreading more widely across the country. Compared with the 2023 survey, the number of municipalities with no such students declined, while those with 20 or more increased by about 10%.
