i-socia Advisors works from Uchihommachi in Osaka and serves the Kansai region: Osaka, Kyoto, Hyogo, Nara, Shiga and Wakayama. It is one of the few firms in this directory based outside Tokyo that presents itself in English.
It covers both KK and GK incorporation and a wide range of visa categories, and states explicitly that company registration and visa application are entirely different procedures — a distinction founders routinely conflate, and one that decides whether you need one firm or two. Corporate bank account opening is referenced. A fee structure page exists but no figures appeared on the page we checked. Note that the firm states it does not take enquiries by phone or Skype: the first consultation is by email.
