Japan's accounting qualifications: KKS vs Zeirishi

Japan's accounting profession is split along two distinct tracks, which shapes the salary landscape considerably.

The Konin Kaikeishi (公認会計士, KKS) — the Japanese CPA — is required for auditing listed companies and public interest entities. The examination is three-stage and extraordinarily demanding: the first stage tests basic accounting; the second (the main barrier) tests financial accounting, audit theory, enterprise law, and tax law simultaneously; the third is a practical oral examination. Overall pass rates hover between 8-11%. Most candidates take 2-5 years of dedicated study to pass, often enrolling in specialist CPA prep schools (Tac, CPA, Lec) that cost ¥400,000-¥800,000 in fees.

The Zeirishi (税理士, licensed tax accountant) is a separate qualification requiring passing five subject examinations over time (subjects can be passed individually across multiple years, which is more forgiving). Zeirishi primarily serve SMEs and individuals on tax compliance, planning, and advisory work. Japan has approximately 80,000 Zeirishi compared to around 35,000 KKS holders. Zeirishi in private practice can earn considerably more than the employed averages suggest, particularly those building a strong SME client roster in major cities.

Big Four Japan: where the top salaries are

The four major audit firms in Japan — Deloitte Tohmatsu, PricewaterhouseCoopers Japan (PwC Aarata Audit / PwC Tax & Advisory), KPMG Azsa, and Ernst & Young ShinNihon — collectively audit nearly all of Japan's Nikkei 225 constituents and most TSE Prime-listed companies.

Note that EUR equivalents use approximately ¥160/€ — the yen's level through 2024-2026. Japanese Big 4 salaries look modest in EUR terms partly because of this structural weakness; in purchasing power parity terms, the gap with European counterparts is smaller than the raw conversion suggests.

IFRS expertise and the premium it commands

Japan is in the midst of a slow but accelerating shift toward IFRS adoption. As of 2026, approximately 250 companies voluntarily apply IFRS for their consolidated financial statements — including Toyota, Sony, SoftBank, and Recruit Holdings. The number is increasing annually following FSA encouragement.

KKS holders with demonstrated IFRS expertise command a salary premium of ¥1,000,000-¥2,000,000 above colleagues without it. This reflects genuine scarcity: Japan's accounting education system remains oriented toward Japanese GAAP (J-GAAP), and the IFRS body of standards requires substantial additional training and often international experience to master.

Financial services — banks, asset managers, insurance companies — also pay premiums for accountants familiar with JFSA requirements and Basel III/IV capital calculations. Nomura, Daiichi Life, and the major regional banks all maintain significant internal finance functions that recruit KKS holders at above-average compensation.

Zeirishi in private practice: the other path

Many Zeirishi operate their own accounting practice, building a client base of local businesses, restaurants, clinics, real estate companies, and self-employed individuals. The income from private practice varies enormously: a newly licensed Zeirishi building their first clients might earn ¥3,000,000-¥4,000,000; an established practitioner with 200 SME clients and a small staff might generate ¥15,000,000-¥25,000,000 in fees.

For self-employed Zeirishi, the tax calculation differs: they pay kosei nenkin as jigyonushi (business owner) at double the employed rate for their portion, and their income tax is calculated on business profits rather than employment income. The deduction structure differs meaningfully — many Zeirishi manage their personal and business expenses carefully to optimize their effective tax rate.
