Aurora serves as the bilingual U.S. point of coordination on tax and finance matters — working directly with the banks, legal counsel, and external advisors these organizations engage. While particularly experienced in serving Japanese businesses and executives, Aurora also works with U.S. and international clients.
Japan HQ needs a bilingual U.S. advisor to coordinate tax, reporting, and finance across the Pacific.
A U.S. subsidiary needs a senior outside advisor to oversee tax and reporting and interface with Japan.
Expatriate executives and secondees need U.S. individual tax and foreign-asset reporting handled with discretion.
A Japanese group is expanding, restructuring, or reviewing its U.S. footprint.
Management needs one U.S. point of coordination across local accountants, payroll, and counsel.
Technical U.S. tax or finance matters must be put into clear business terms for Japan-side decision-makers.
