Acceptable proof is a JLPT N2 certificate or CEFR B2-equivalent documentation, held by either the visa applicant or the company's qualifying full-time employee, not a self-declared claim of fluency. Since the October 16, 2025 reform, this is a documented limb of the Business Manager visa (経営・管理) standard under the Immigration Control Act (入管法), and examiners reject files where the proof is asserted rather than attached.
What Counts as Acceptable Proof of Japanese Ability?
A JLPT N2 certificate is the clean documentary route because it is a fixed, dated, third-party-issued credential the examiner can check against a published pass list. CEFR B2-equivalent evidence (an accredited language-school transcript, a recognized proficiency exam other than JLPT, or comparable formal certification) is accepted but invites more scrutiny than a JLPT certificate, since CEFR mapping to Japanese proficiency is less standardized in immigration practice than the JLPT scale itself.
A common founder error is assuming N1, the highest JLPT tier, is what the file needs. It is not. N2 is the floor set by the reform; N1 clears a higher bar than the requirement asks for, and founders who spend a year chasing N1 before filing are solving a problem the examiner never posed. If the applicant or the qualifying employee already holds N2, that credential is filing-ready; nothing about N1 makes the file stronger in a way that changes the outcome.
What does not count: a cover-letter statement that the applicant "speaks Japanese daily," a claim of childhood immersion without a certificate, or a business plan that references "fluent Japanese staff" without naming the employee and attaching their score report. Per the October 2025 reform guide, the reform replaced several soft, discretionary standards with hard documentary thresholds, and language proficiency is one of them. Examiners want the certificate in the file, not a description of the applicant's ability.
Does the Founder Have to Speak Japanese Personally?
No. The requirement can be satisfied through the applicant's own N2/B2 credential or through the qualifying full-time employee's credential, and either route clears the same limb. This matters directly for a founder whose Japanese is weak but whose one required local hire is a native speaker or an N1-level bilingual professional.
The qualifying employee requirement (a Japanese national, Special Permanent Resident, Permanent Resident, spouse or child of a Japanese national, or Long-Term Resident hired full-time) exists independently of the language limb, but in practice the two requirements are frequently solved by the same person. A founder who hires a Japanese national as the required full-time employee has, in the same hiring decision, produced the documentary language proof: the employee's own JLPT N2 or native-level credential satisfies limb (c) without the founder needing to sit an exam. This is the sequencing point worth planning around before filing, not after a rejection.
Where the founder does hold their own N2 or B2, the employee's language ability is irrelevant to this limb; the requirement is satisfied by whichever person has the documented credential. The two paths are alternatives, not additive, and a file only needs one certificate attached, clearly labeled with whose credential it is.
Key points:
(a) JLPT N2 or CEFR B2-equivalent documentation is the actual floor; N1 exceeds what the reform requires and is not necessary to clear the limb.
(b) The credential can belong to the applicant or to the qualifying full-time employee; either satisfies the requirement, and founders with weak Japanese often clear this limb through their required hire rather than their own study.
(c) The certificate must be in the file at filing. A cover-letter assertion of fluency, with no attached score report or transcript, is the documented failure mode examiners cite under "language proficiency not documented."
What Happens at Renewal if the Qualifying Employee Leaves?
Renewal risk concentrates exactly where a founder solved both requirements through one hire: if that employee leaves, the company can simultaneously lose its qualifying full-time employee and its documented proof of language ability, since both limbs may have rested on the same person. This is a distinct and common renewal failure mode, separate from the capital or business-plan limbs, because nothing about the initial approval forces the company to notice the exposure until the renewal file is due.
A company that filed its initial application with the founder speaking limited Japanese and one native-speaking employee on payroll has, from the examiner's perspective, two limbs sitting on one headcount line. If that employee resigns before the renewal window, the file needs a replacement hire who is both an eligible qualifying employee under the status categories and a documented N2/B2 holder, or the founder needs to have independently reached N2 in the interim. Neither substitution happens automatically, and neither is quick: sourcing an eligible replacement and onboarding them with registered payroll and social insurance before the renewal filing is a lead-time problem, not a paperwork problem.
The practical response is to track this dependency the moment the qualifying employee is hired, not at the renewal deadline. Companies that treat the qualifying employee as a single point of failure for two separate visa limbs build in a contingency (a second bilingual hire, or founder language study running in parallel) well before the renewal clock forces the issue. For the entity-formation and business-plan side of the same filing, see the companion piece on who can certify a Business Plan for the Management Visa; staffing a firm with immigration filing experience through Aplash's Management Visa service is where this sequencing gets planned rather than discovered after a rejection notice.
Frequently Asked Questions
Does the Management Visa applicant need to pass JLPT N2 personally?
No. The October 2025 reform allows the language requirement to be satisfied by either the applicant or the company's qualifying full-time employee. A founder with limited Japanese can clear this limb entirely through a native-speaking or N2-certified employee, provided that employee also meets the separate eligibility categories for a qualifying employee.
Is N1 required, or is N2 enough?
N2 is the actual floor set by the reform; CEFR B2-equivalent documentation is the accepted alternative standard. N1 is a higher tier than the requirement asks for, and pursuing it before filing does not change the outcome if N2-level proof is already in hand.
Can a company lose its Management Visa status at renewal over the language requirement?
Yes, if the person who supplied the documented language proof was also the qualifying full-time employee and that person leaves the company. Both limbs can lapse at the same time, which is why the dependency between the hiring decision and the language limb needs tracking from the date of initial approval, not left until the renewal filing is due.
Conclusion
The language limb of the Management Visa standard is a documentation exercise, not a fluency test in the abstract: a JLPT N2 certificate or CEFR B2-equivalent record, attached to the file and attributed to either the applicant or the qualifying employee, is what an examiner needs to see. The failure mode is administrative, not linguistic, whether at initial filing through an undocumented claim or at renewal through an unreplaced qualifying employee, and both are avoidable with the credential tracked from the point the hiring decision is made.
