What We Offer?
English-Language Accounting Services
We offer comprehensive financial accounting services in English, payroll processing outsourcing, and more.
Our team facilitates seamless communication and consultation in English, ensuring high-quality support in areas such as preparing English-language reports, managing expense payments for foreign-affiliated companies, and handling financial payroll processing.

International Taxation Services
We offer comprehensive support for international taxation and tax filing, specializing in the complex tax challenges unique to foreign-affiliated companies.
From assisting with market entry requirements and preparing proposals for your home country to explaining relevant laws and regulations, we deliver expert guidance.

Payroll Services
Our payroll services are designed to meet the diverse needs of foreign-affiliated companies, offering support for payroll processing, HR consultations, and recruitment solutions.
We provide end-to-end assistance, including monthly payroll processing, procedures for company establishment or relocation, and year-end adjustments. Our services also cover English explanations for foreign staff, gross-up calculations, and approved rent calculations. For employees returning to their home countries, we assist with preparing income tax returns and managing tax payments, acting as their designated tax agent. We also handle termination-related issues. Given that HR decisions in foreign-affiliated companies are often driven by headquarters, conflicts can arise with Japanese staff during workforce reductions. As a neutral intermediary, we facilitate the process by gathering termination details from headquarters HR, explaining them to the employees affected, and overseeing the dismissal procedures to ensure a smooth transition. Additionally, we support labor-management negotiations and communication, provide guidance to overseas HR teams on Japanese HR practices, and draft employment regulations in both Japanese and English to bridge cultural and procedural gaps effectively.

Banking and Corporate Services
We offer bank payment agency services and corporate management custody support, catering to the needs of foreign-affiliated companies.
Our services include assisting with bank account setup for newly established businesses, payments through corporate accounts, and handling HR-related personal document management as part of overall managing company administration. As a core area of expertise, we excel in BPO (Business Process Outsourcing) and accounting outsourcing. Our team provides prompt and accurate English-language bookkeeping services, with inquiries handled efficiently via English email. In addition, we deliver comprehensive guidance on Japanese tax regulations, accounting standards, and financial management to ensure compliance and operational efficiency.

Governance and Director Services
As the number of foreign-affiliated companies entering the Japanese market continues to grow, there has been increasing demand for our external director and auditor appointment services.
Our experienced professionals can assume roles such as external directors or representative directors to meet your corporate governance needs. Although recent legal reforms allow foreign residents to be registered as representatives of domestic corporations, many foreign-affiliated companies listed on overseas stock exchanges still prefer appointing representatives such as subsidiary representative directors, executive directors, or Japanese representatives for foreign corporations. These appointments are often driven by organizational management requirements and practical considerations. Furthermore, we can take on roles such as auditors or accounting advisors for Japanese subsidiaries of overseas companies, offering reliable support for accounting audits and other related tasks.

Tax Refund Services
Foreign corporations (non-residents) are entitled to claim refunds for Japanese consumption tax and European VAT refunds for Japanese companies.
We provide comprehensive support for filing these refund claims on your behalf. For example, when foreign airlines begin operations in Japan, they are subject to consumption tax filings. Taxable expenses such as repairs to aircraft engines removed during maintenance, parking security fees, in-flight news and advertising videos unrelated to cargo handling, as well as domestic lodging, meals, and transportation costs for crew members, are eligible for refunds under Japanese consumption tax regulations.

Internal Audits Services
We offer corporate investigation and internal audit services for Japanese companies, focusing on crisis management and financial investigation support to prevent internal crimes.
These services are essential for all businesses, not just publicly traded companies, as compliance and fraud prevention are critical components of modern corporate operations. Our services also include conducting detailed financial assessments of potential business partners. By adopting a proactive approach to crisis management—understanding comprehensive strategies and implementing preventive measures—companies can mitigate risks and ensure swift and effective responses to any unforeseen challenges.

Transfer Pricing Services
Developing a transfer pricing model suited to foreign-affiliated companies often involves adopting the "Transactional Net Margin Method" (TNMM) rather than the standard three methods, as identical or comparable transactions are typically unavailable.
This approach enables us to construct an appropriate framework and prepare the required documentation effectively. Our firm partners with former National Tax Agency specialists in transfer pricing to deliver precise, practical advice. By aligning our recommendations with the unique circumstances of each case, we ensure compliance and provide realistic solutions tailored to your operational needs.

Talent and HR Support Services
We provide comprehensive support for foreign-affiliated companies in recruiting recruited personnel to strengthen their operations in Japan.
Our services include adapting employment contracts from the home country to align with Japanese practices and creating employment contracts tailored to the needs of the Japanese subsidiary. We also offer expert advice on labor law compliance. Many issues arise due to unfamiliarity with Japan's labor laws, particularly regarding overtime regulations and termination clauses, which are strictly defined under Japanese labor standards law. These challenges are frequently seen when headquarters lacks an understanding of the local requirements. In Japan, companies are required to establish a General Rule of Employment and separately specify individual employment terms. We provide the necessary guidance and support to ensure clients fully understand and comply with these systems, enabling smooth and lawful employment management.
