What It Is

IATS（International Affairs Total Service） is a comprehensive support provider for overseas companies entering and operating in Japan. It positions itself as offering “one execution framework” that integrates company incorporation, legal and administrative applications, tax and financial operations, and visa support. Its focus is not merely filing registration documents, but providing continuous support around establishment, compliance, and operational preparation for companies entering the Japanese market.

Core Services and Coverage

Based on the site content, IATS covers the Japanese jurisdiction. Its core services include Japan company incorporation, company registration, changes to registered matters, changes to business purposes and representatives, capital adjustments, drafting articles of incorporation, and amending articles of incorporation. On the administrative and legal side, it can assist with filings to government offices, document applications, and preparation of compliance documents, and says it works with administrative scriveners and other specialists. For tax and finance, services include basic compliance, monthly bookkeeping, financial analysis, and year-end closing support. For visas, it supports Business Manager visas, Dependent visas, and procedures related to status of residence.

Pricing and Processing Time

The website does not disclose pricing, packages, government fees, consulting fees, or payment methods, making it difficult to assess cost transparency and value for money. In terms of processing time, IATS states that company incorporation is usually completed in about 1 to 4 weeks, though this depends on document preparation and the processing status of the relevant authorities. Its incorporation process is divided into 7 steps: confirming the company’s basic structure, deciding the company name and business purposes, preparing documents, drafting and notarizing the articles of incorporation, paying in capital, applying for registration with the Legal Affairs Bureau, and obtaining the completed registration documents.

Pros and Cons

The main advantage is its complete service chain: it can coordinate company incorporation, administrative procedures, tax and finance, and visa matters through a single point of contact, which is useful for overseas companies unfamiliar with Japan’s system and can reduce communication and compliance costs. The website also clearly lists common pain points, such as complex administrative procedures, strict document requirements, high language and communication costs, and unpredictable processing times. The drawbacks are the lack of disclosure on key information: there are no quotes, payment methods, supported languages, details on team qualifications, or case studies. It also does not state whether it provides virtual addresses, registered addresses, registered agent services, or arrangements for a representative director.

Who It’s For and Access from China

IATS is better suited to overseas companies planning to establish a Japanese company, cross-border e-commerce businesses, financial investment and real estate-related companies, SMEs expanding into Japan, and shareholders or executives who need a Business Manager visa. Access from China cannot be determined from the site content alone; direct network access, payment methods, and Chinese-language service are not disclosed. Chinese users evaluating IATS may also want to compare it with local Japanese administrative scrivener firms, tax accountant offices, and cross-border compliance service providers that offer Japan company incorporation.
