Inbound Support / English & Chinese

Can I consult with you about taxes in English or Chinese?
Yes. We provide services in English and Chinese (Simplified). Four native Chinese-speaking staff members can communicate with you directly, without an interpreter. We are also fully comfortable working in English.
How can you help foreign entrepreneurs set up a company in Japan?
We provide end-to-end support, from post-incorporation filings with the tax office, prefecture, and municipality, to accounting software setup, year-end closing, and tax filing. Through our partners who are experienced with international clients, we can introduce judicial scriveners for company registration, administrative scriveners for visa applications, and labor and social security attorneys for social insurance procedures. We can also introduce recruitment agencies if you are looking to hire English- or Chinese-speaking staff.
Can you apply for a Business Manager visa for me?
Visa applications are handled by administrative scriveners (gyoseishoshi), so we do not file them ourselves, but we can introduce a partner administrative scrivener. Visa renewals require documents such as your company's financial statements and tax payment certificates, and we help you prepare them. For visa requirements, please check the website of the Immigration Services Agency of Japan. Immigration Services Agency of Japan
Do you support overseas companies setting up a subsidiary or branch in Japan?
Yes. After your Japanese subsidiary or branch is established, we handle tax advisory, bookkeeping, year-end closing and tax filing, and year-end payroll adjustment, all in English or Chinese. We can also prepare English reports for your overseas headquarters. We frequently advise on consumption tax refunds, for example after large initial investments, and on how to set and document payments to headquarters, such as management fees and royalties.
Do you work with restaurants and retail shops run by foreign owners?
Yes. Many of our clients are in the restaurant, retail, and import/export industries. We also help with financing for startup and working capital, including preparing documents for financial institutions.

Can you help us set up a holding company?
Yes. We support you from designing the structure through implementation. Companies set up holding companies to make business succession easier, manage the group more efficiently, separate risks by business, and prepare for future M&A.
