Forvis Mazars is the firm in this directory to look at if you will eventually need a financial audit as well as tax compliance — most of the practices listed here do tax and accounting but not audit. It describes itself as specialising in cross-border business and assisting foreign-owned companies operating in Japan, with international desks globally.
Its stated services in Japan cover financial audit and assurance, national and domestic tax compliance, and HR and payroll outsourcing. Incorporation, visa work and bank account support are not mentioned, so this is a firm for the ongoing compliance relationship rather than the setup itself.
The global network is stated at 40,000 professionals across more than 100 countries and territories. Japan staff numbers, the year the Japan practice was founded, and fees are not published.
