Foreign companies wishing to engage in contituous transactions
in Japan must register with Legal Affairs Bureau in Japan.

To do so, at least register

1. the appointment of a representative in Japan.
2. the establishment of a branch office.

A Japanese branch office is a business location that provides
services in Japan decided upon by an organization authorized
by the foreign company, and ordinarily is not expected to engage
in independent decision making. A branch office does not have its
own legal corporate status, but instead is deemed to be encompassed
within the corporate status of the foreign company.

In general, therefore, the foreign company is ultimately responsible
for all debts and credits generated by the activities of its Japanese
branch office.
