Background checks: what's actually required versus what employers add
Japan's national work visa process doesn't have a standard criminal-check requirement the way Korea's E-2 does, so Canadians shouldn't assume they need an RCMP check by default. JET and some larger dispatch ALT companies do run their own background screening as part of hiring, which may include asking for an RCMP-style clearance, so this is an employer-level requirement to confirm, not a universal immigration rule.
If a specific employer asks for one, the RCMP fingerprint-based check through an accredited fingerprinting service is the standard document Canadians use, the same one used for Korea's E-2 process, and it's worth getting early since processing time is unpredictable.
