Unofficial estimate for planning. Different systems mark differently, so we map achievement level (not raw percentage). Official applications need a credential evaluation.
Converting Nigeria grades for study in Japan
Applying to a Japan university with a Nigeria transcript means translating your marks into the local system: Japanese GPA. Enter your grade above for an instant estimate, and use the full table below to see how each band maps.

How the Japan system works
Japanese universities assess transcripts directly; JASSO offers guidance. Note a native Japanese GPA is computed on a deflated scale, so evaluate the underlying grades rather than copying a GPA across.
Is it competitive?
Most Japan master's programmes look for the equivalent of a US 3.0+ (an upper-second / good average), with competitive and funded programmes wanting more. Convert first, then check each programme's stated minimum. For a credit-weighted multi-course result, use the WES iGPA calculator.
Frequently asked questions
How do Nigeria grades convert to the Japan system?
We map your Nigeria grade to a US 4.0 equivalent, then into Japan's own scale (Japanese GPA) using standard credential-evaluation bands. It's an unofficial estimate — see the table above for the full mapping.
Is this an official conversion?
No. Use it for planning and shortlisting. Japanese universities assess transcripts directly; JASSO offers guidance. Note a native Japanese GPA is computed on a deflated scale, so evaluate the underlying grades rather than copying a GPA across.
What Nigeria grade do I need to study in Japan?
It depends on the programme, but a strong upper-tier %s result (roughly a US 3.0+ equivalent) is competitive for most master's programmes; selective and funded programmes expect more.
