Fractional and interim C-suite leadership in Tokyo

Japan has no statutory redundancy pay, which sounds permissive until you read Article 16 of the Labor Contract Act: a dismissal is void without objectively reasonable grounds. In practice a full-time senior hire is close to irreversible, and negotiated executive exits run three to twelve months of salary as market practice rather than statute.

So Japanese companies buy expertise on a gyomu itaku delegation contract instead. The distinction from employment is substantive, not cosmetic — direction, fixed hours, exclusivity and integration convert it back to employment retroactively.

The demand behind it is demographic. METI’s SME White Paper identifies business succession as the dominant structural issue: a large cohort of owner-managers past retirement age with no successor, needing CFO-grade capability for a twelve to twenty-four month handover.

The numbers

Fractional, per month¥600,000–1,800,000/month (USD 3,800–11,300) at one to two days a week; ¥300,000–500,000 for advisory-only komon arrangements.
Full-time, all-inCFO base around ¥15m junior, ¥20m median and ¥30m+ senior in commercial businesses. All-in with employer social insurance and bonus: ¥25m–40m, roughly USD 157,000–252,000.
Corporate taxNational 23.2%, with a 15% SME rate on the first ¥8m of income for companies capitalised at ¥100m or less. Adding local corporate, enterprise and inhabitants’ taxes, the Tokyo effective rate is 35.43% for smaller companies and 31.52% for larger ones.
VAT / GSTConsumption tax 10%, with an 8% reduced rate. Since October 2023 the Qualified Invoice System means an unregistered consultant breaks the client’s input credit chain.
Employer on-costsAround 15% of salary plus workers’ accident insurance. Health at about 4.955% on a standard remuneration cap of ¥1,390,000; welfare pension at 9.15% on a ¥650,000 monthly cap; employment insurance 0.9%; long-term care 0.795% for ages 40–64. The pension cap means employer cost flattens sharply at senior salaries.
SeveranceNo statutory redundancy pay. Thirty days’ notice or pay in lieu. The real constraint is Article 16 — dismissal is void without objectively reasonable grounds, and courts apply a four-factor test to redundancy. Negotiated executive packages typically run three to twelve months.
Work permitsForeign nationals working in Japan need status. Routes are the Business Manager visa — now much harder — Highly Skilled Professional, or Engineer/Specialist in Humanities through a sponsoring entity. Delivering from offshore with no permanent establishment avoids it; non-resident directors’ fees attract 20.42% withholding.

What actually governs this in Japan

The regimes that change the answer, rather than the ones that sound like they should.

Representative director

Every KK needs at least one. No director must be Japan-resident since 2015, but banks and the Legal Affairs Bureau in practice expect a Japan address, and a fractional executive taking the seat assumes personal liability under Article 429.

Shain versus gyomu itaku

An employment contract triggers social insurance, Labor Standards Act protection and dismissal restrictions. A delegation contract does not. Substance governs — direction, fixed hours, exclusivity and integration convert it retroactively.

Freelance Act, in force November 2024

Mandates written terms, payment within 60 days of delivery, and bars unilateral reduction or refusal. It applies to solo-operator fractional executives engaged company-to-company.

Business Manager visa reform, October 2025

Capital raised from ¥5m to ¥30m, one full-time Japanese or permanent-resident employee required, JLPT N2-level Japanese, and a business plan certified by a professional. Transitional treatment for existing holders runs to October 2028.

Why companies here buy it

  • The lifetime-employment norm and Article 16 make a full-time senior hire near-irreversible, so companies buy expertise on a delegation contract.
  • Succession-stage SMEs need CFO-grade capability for a twelve to twenty-four month sale or handover, not permanently.
  • Foreign entrants face a much harder Business Manager visa since October 2025, pushing them toward a local fractional representative director rather than relocating a founder.

How business is done

  • Authority is registry-based and seal-based, not title-based. Whoever holds the company seal and the representative director registration signs. A fractional CFO without that seat is a komon — an adviser — and banks will not accept them as binding the company.
  • Senior hiring runs through introduction far more than search. A mid-career external C-suite hire is still non-standard at established firms.

Market context

  • Around 3.3 million SMEs, 99.7% of enterprises, with Tokyo holding the largest concentration nationally.
  • METI identifies business succession and handover as the dominant structural issue facing Japanese SMEs.
