JAPAN VISA SUPPORT is one of the few firms that puts a Business Manager Visa figure on its own site rather than quoting on request, and it publishes it as a band rather than a single number — which is honest, because the work varies enormously with how close an applicant already is to the criteria.
The firm states that all its lawyers are Japanese and fluent in English, and that clients can complete the procedures from home using a smartphone or PC through its intake tool. It is based in Kawasaki rather than central Tokyo, which matters less than it used to given the remote process. Incorporation and tax work are not mentioned, so this is a visa-only engagement.
