Introduction
People look for an Accountant / CA in Tokyo for one simple reason: compliance is high-stakes here. Between Japanese corporate tax filings, consumption tax (JCT), payroll/social insurance administration, and increasingly complex cross-border reporting, even “simple” bookkeeping can become time-consuming and risky.
This guide shows you the best-known, clearly established Accountant / CA firms serving Tokyo—especially for businesses that need reliable tax, audit, and finance support in Japanese and English.
Our selections prioritize firms with a well-documented Tokyo presence and clearly stated service lines. Review summaries are included only where publicly available and confidently known; otherwise, they are marked as Not publicly stated.
About Accountant / CA
An Accountant / CA helps individuals and businesses record financial transactions accurately, prepare financial statements, manage taxes, and stay compliant with local regulations. In Tokyo, many clients also need bilingual support, group consolidation help, and cross-border tax coordination (especially for foreign-owned companies).
You typically need an Accountant / CA when you’re:
- Starting a company and choosing a structure (KK vs GK, etc.)
- Setting up bookkeeping, payroll, and monthly reporting
- Preparing annual financial statements and corporate tax filings
- Managing consumption tax (JCT) filings and invoices
- Undergoing an audit or due diligence (investment/M&A)
- Expanding into Japan and needing local finance operations
Average cost in Tokyo: Varies widely based on complexity and provider type. As a general market reference, small-business monthly bookkeeping can range from tens of thousands of yen per month to significantly more for multi-entity, bilingual, or high-volume operations. Annual tax filings and advisory projects are commonly quote-based.
Licensing/certifications in Japan (important nuance):
“CA” is not the standard Japanese title. In practice, you may need one (or more) of the following licensed professionals depending on the work:
- Japanese CPA (公認会計士 / Kōnin Kaikeishi): commonly involved in audits, assurance, and high-level accounting advisory.
- Licensed Tax Accountant (税理士 / Zeirishi): typically required for tax agent services and tax filings/representation.
- Audit firms (監査法人) staffed by CPAs for statutory audits.
Key takeaways
- Match the provider to the job: tax filing (Zeirishi) vs audit/assurance (CPA/audit firm) vs outsourced accounting.
- In Tokyo, bilingual capability and cross-border experience often matter as much as price.
- Pricing is usually retainer-based (monthly) for ongoing work and fixed/quote-based for annual filings or projects.

Average price range (general guidance):
- Basic monthly bookkeeping for small businesses: commonly tens of thousands of yen per month and up, depending on volume and reporting requirements.

- Audit, due diligence, and transaction advisory: typically project-based and can range widely.

- Payroll headcount and complexity (bonuses, allowances, expatriates)

- Cross-border factors (foreign parent reporting, intercompany, transfer pricing, multiple currencies)
Frequently Asked Questions (FAQ)
How much does a Accountant / CA cost in Tokyo?
It varies by scope and provider type. Ongoing bookkeeping is often priced monthly, while tax filings and advisory are frequently quote-based. Expect higher fees for bilingual reporting, complex JCT handling, or cross-border work.
How to choose the best Accountant / CA in Tokyo?
Start with the exact deliverable you need: bookkeeping, tax filing/representation, payroll, audit, or advisory. Then confirm language support, relevant credentials (CPA/Zeirishi where needed), and whether they can meet your reporting deadlines.
Are licenses required in Tokyo?
For certain services, yes. Tax agent services and tax filings generally require a Zeirishi. Statutory audits require a qualified Japanese CPA working within an appropriate audit framework. Some bookkeeping support may not require a license, depending on the task.
What’s the difference between a Japanese CPA and a Zeirishi?
A Japanese CPA is commonly associated with audit/assurance and advanced accounting. A Zeirishi specializes in tax filings and tax representation. Many business clients in Tokyo use both, depending on needs.
Do these firms support English-speaking clients in Tokyo?
Large international networks commonly support English-speaking and multinational clients, but service availability varies by team and engagement. Confirm bilingual deliverables (reports, emails, meetings) before signing.
Can an Accountant / CA help with company formation in Tokyo?
Many firms can support early-stage setup such as accounting/tax planning, initial bookkeeping design, and compliance calendars. Legal incorporation steps may require coordination with other licensed professionals; service coverage varies.
Who offers 24/7 service in Tokyo?
24/7 accounting support is uncommon. Some firms can accommodate urgent deadlines or global time zones on a project basis, but availability is typically arranged in advance and may involve rush fees.
What documents should I prepare before contacting an Accountant / CA?
Common starting points include bank statements, sales invoices, vendor bills, payroll details, prior-year financials/tax returns (if any), and a summary of your business model. For cross-border cases, include parent-company reporting requirements.
How long does it take to switch accountants in Tokyo?
Timing depends on record quality and your reporting cycle. A clean handover can be completed quickly, but cleanup bookkeeping, missing documents, or mid-year transitions can extend the timeline.
Should I choose a big firm or a smaller local office?
Big firms are strong for complex advisory, audits, cross-border tax, and structured governance. Smaller offices can be more cost-effective for routine bookkeeping and local tax filings—provided they match your industry and language needs.
Final Recommendation
Choose Deloitte Tohmatsu, PwC Japan, KPMG AZSA/KPMG Japan, or EY Japan if you need premium, enterprise-grade support—especially for cross-border reporting, audit readiness, complex tax questions, or transaction work. These are best suited for multinational companies, funded startups preparing for diligence, and organizations with strict governance requirements.
Consider BDO Japan if you want a mid-market to premium option with international network coverage and potentially more flexible engagement structures (availability and fit vary by team and scope).
If your priority is lowest cost for straightforward bookkeeping, many smaller Tokyo-based practices may be a better fit—but they are not included here because consistent, verifiable public details (official websites, services, and review signals) are not always publicly stated.
