Corporate Accounting Obligations in Japan

Published on May 3, 2026 and written by Cyril Jarnias

Japan, with one of the world’s largest economies, imposes precise and structured accounting obligations that directly influence the management of companies operating in the country. Compliant with international standards while maintaining national specificities, these obligations reflect a balance between tradition and modernity, ensuring transparency and trust with business partners. This involves a complex framework where companies must not only comply with strict financial reporting requirements but also navigate between different local and international regulations. Understanding these obligations is crucial for any organization seeking to establish or expand operations in Japan.

Legal Requirements for Financial Reporting in Japan

Legal requirements for financial reporting in Japan are primarily regulated by the Financial Instruments and Exchange Act and the Companies Act. These laws define different obligations depending on the type and size of the company. Additionally, accounting standards applied in Japan include JGAAP (Japanese Generally Accepted Accounting Principles) and IFRS (International Financial Reporting Standards).

Main Laws and Regulations

Financial Instruments and Exchange Act

• Listed companies are required to submit a securities report to the Prime Minister within three months after the end of the fiscal year. This document includes a wide range of information such as financial statements and management status.
• Semi-annual interim reports as well as quarterly accounts are also required, with external auditor review necessary in some cases.

Companies Act

• Balance sheet publication is required for all joint-stock companies, and for large companies, the income statement is also included.
• The method of publishing financial results allows for insertion in the Official Gazette or newspapers, but in some cases, website publication is also permitted.
• Non-listed companies also have basic financial publication obligations. However, it is often observed that small non-listed companies do not implement them.

Listed Companies vs Non-Listed Companies

Element	Listed Companies	Non-Listed Companies
Preparation and submission of financial statements	Obligation to prepare a securities report as well as quarterly and interim financial statements	Annual preparation and publication of balance sheet
Audit by external auditor	Mandatory	Generally not required except for exceptions
Submission deadline	Within three months after fiscal year end	Generally none
Accounting standards	JGAAP or IFRS	Primarily JGAAP

Accounting Standards

1. JGAAP (Japanese Accounting Standards): Standard accounting principles widely used in Japan. In some areas, harmonization with international standards is considered.
2. IFRS (International Financial Reporting Standards): Adopted by some large Japanese companies operating internationally. Option available particularly for companies listed on the Tokyo Stock Exchange main market.

Legal Compliance and Challenges

1. General Challenges
   • Response to legislative revisions: Need for specialized knowledge to track regular changes.
   • Financial burden of external audit: Represents increased costs particularly for small and medium-sized enterprises.
2. Penalties for Non-Compliance
   • In case of violation of the Financial Instruments and Exchange Act, administrative measures such as correction orders or fines may be imposed. Companies may also face risk of damage claims from investors in case of improper disclosure.
   • Violation of the Companies Act also results in penalties such as fines.

Understanding Accounting Obligations for Japanese Companies

1. Japanese Generally Accepted Accounting Principles (JGAAP)

• JGAAP are unique accounting standards in Japan, widely adopted by domestic companies. They include as a foundation the “Corporate Accounting Principles,” with pillars being “General Principles,” “Income Statement Principles,” and “Balance Sheet Principles.”
• One characteristic is their easy compliance with Japanese laws and taxation, making them suitable for companies focusing on SMEs and the domestic market. Conversely, they may be unsuitable for expansion into international markets.

2. Specific Requirements of the Financial Services Agency (FSA)

• The FSA defines rules for preparing financial statements and provides a legal framework such as the “Regulation on Financial Statements.” Listed companies must adhere to strict presentation and submission deadlines. Additionally, the Financial Instruments and Exchange Act also influences by emphasizing transparent reporting.

3. Impact of Commercial Law Accounting Principles (BAP)

• Article 431 of the Commercial Code stipulates the obligation to maintain accounting books in accordance with practices deemed fair and reasonable. These commercial law-based practices share many similarities with JGAAP, although some minor differences exist.

4. Recording Accounting Books, Preparing Annual Financial Reports, Submission Deadlines

• According to the Companies Act, all joint-stock companies must record daily transactions in accounting books in an orderly and clear manner.
• Annual financial reports (financial statements) are generally approved during the general shareholders’ meeting within three months after the fiscal year end and are then submitted to the competent authority.

5. Regulatory Compliance Through External Audit

• For listed companies and those of a certain size, external audit by a certified public accountant or audit firm is mandatory. This not only contributes to fraud prevention and investor protection but also enhances reliability with the FSA.

6. Listed Companies vs Small and Medium Enterprises: Differences in Obligations

Element	Listed Companies	Small Non-Listed Companies
Accounting standards	JGAAP/IFRS/US-GAAP/JMIS	Primarily JGAAP
Financial reports	Quarterly and annual	Annual only
External audit	Mandatory	Generally not required

Small non-listed companies do not require external audit, but simplified systems exist as support measures for SMEs.

7. Recent Reform Trends and Examples

In recent years, harmonization with international standards has progressed in Japan. For example, large Japanese manufacturers operating globally have received high evaluations from foreign investors thanks to transitioning to IFRS. Additionally, starting from fiscal year 2024, the introduction of new revenue recognition standards is also on the agenda.

All these elements show a dual framework consisting of responding to Japan-specific elements as well as international standards, offering diversity of choice accompanied by efforts to ensure transparency.

Corporate Balance Sheets in Japan: Rules and Practices

Main Components

Japanese corporate balance sheets consist of three main parts:

• Assets: Resources with economic value held by the company. They are classified as current assets (cash, receivables, inventory, etc.) and fixed assets (real estate, equipment, tangible and intangible fixed assets, etc.)
• Liabilities: Elements acquired from third parties, with repayment obligations, including current liabilities (short-term loans, accounts payable, etc.) and non-current liabilities (long-term loans, bonds, etc.)
• Equity: Remaining profits after deducting liabilities, owed to owners or shareholders. They include share capital, retained earnings, stock warrants, etc.

All these elements are recorded according to the “gross total rule” principle, prohibiting offsetting of certain items against each other.

Japan-Specific Regulations

In Japan, the preparation of financial statements is governed by the Commercial Code and the Financial Instruments and Exchange Act. Japanese accounting standards (J-GAAP) are generally used, but some listed companies also adopt IFRS standards.

Fundamental Rules for Balance Sheet Preparation:

1. Classify and arrange assets, liabilities, and equity clearly and correctly.
2. Liquidity classification method: record in order of conversion speed to cash.
3. Handle detailed elements such as stock issuance premiums and revaluation gains or losses.

Public Companies vs Private Companies

• Public Companies: Listed companies must submit their quarterly financial statements in annual securities reports, requiring high transparency. They also disclose the “three financial statements,” including the cash flow statement.
• Private Companies: They are required to prepare a balance sheet only at fiscal year end, although this is often done for tax filing purposes.

Audit Requirements

Listed companies must be audited by an external audit firm. However, small and medium non-listed companies are not required to undergo external audit. Nevertheless, large non-listed companies must, under certain conditions, appoint an auditor.

Practical Case Example: Himalaya Co., Ltd.

According to analysis of the balance sheet of sports goods retailer Himalaya Co., Ltd., over 70% of its total assets are held as current assets, enabling high liquidity and operational efficiency. Emphasis is also placed on real estate related to stores and long-term investments as fixed assets. Examining these concrete examples helps understand risk management methods specific to each business sector.

Under this system, the strict rules and detailed classification structure unique to Japan are highly valued by domestic and international investors.

Accounting Standards Applied in Japan

Overview of Japanese Accounting Standards (J-GAAP)

Japanese Accounting Standards (J-GAAP) are a set of accounting rules used in Japan, composed of corporate accounting principles, corporate accounting standards, etc. These are designed considering Japan-specific laws and tax systems and are primarily suitable for domestic companies. Their characteristics include adopting a detailed rules-based approach and emphasizing net profit evaluation (revenues – expenses) from the income statement. Additionally, being based on “conservatism” and the “historical cost principle,” they allow for risk-averse evaluation in financial reporting.

Overview of International Financial Reporting Standards (IFRS)

In contrast, IFRS (International Financial Reporting Standards) are global accounting standards established by the IASB (International Accounting Standards Board). Based on a principles approach, they emphasize transparency and comparability through fair value measurement. For this reason, an asset and liability-focused approach is adopted, providing information primarily centered on the balance sheet. They particularly contribute to promoting understanding by foreign investors and establishing trust in global markets.

Comparison Between J-GAAP and IFRS: Differences and Similarities

Element	J-GAAP	IFRS
Revenue Recognition	Based on detailed rules	Based on principles
Asset Valuation	Historical cost	Fair value
Profit Concept	Non-operating gains and losses, ordinary results, etc.	Comprehensive income only
Consolidation Scope	Focus on control	Control + risks and benefits
Research and Development Costs	Treatment as full expenses	Possible capitalization

In terms of similarities, the fundamental objective of both is to provide appropriate and transparent information to investors and other stakeholders.

Standard-Setting Bodies and Regulatory Authorities in Japan

J-GAAP is primarily developed by the Accounting Standards Board of Japan (ASBJ) under the supervision of the Financial Services Agency. Additionally, the Japan Exchange Group supports the creation of guidelines reflecting the needs of financial statement preparers and users. Furthermore, a modified international standard (J-IFRS) also exists in Japan and is proposed as a flexible option for certain companies.

Impact on Practice: Management, Audit and Transparency

1. Management Strategy: J-GAAP allows easy adjustments for the domestic market, but IFRS also enables adaptation when expanding into international markets, leading many Japanese multinationals to transition.
2. Audit: Although reduction of gaps with global level is required, introduction of new systems may lead to high costs.
3. Transparency: Strengthening information disclosure through IFRS adoption can improve investor confidence. However, promoting understanding also requires educational training.

Recent Reform Trends

In February 2025, in Japan, the ASBJ is studying new guidelines related to financial instruments and the going concern concept. Additionally, the draft guideline related to virtual PPA is scheduled to be published during the same year. These efforts aim to respond flexibly to the rapidly evolving business environment.

Concrete Examples of JGAAP/IFRS:

For example, in the case of automobile manufacturers, analysis of significant equipment investment threshold (including in the form required by IFRS) helped accelerate decision-making involving share reorganization.
