There is no universal JLPT N1 or N2 certificate requirement for all MEXT undergraduate applicants. However, applicants generally take a Japanese-language examination as part of the Embassy Recommendation selection process.
Many MEXT undergraduate scholars undertake preparatory Japanese-language education before entering a university, although the arrangements depend on the scholarship route.
Students should distinguish between MEXT selection requirements and the Japanese proficiency needed to study successfully in a Japanese-taught degree.
