If you are a lawyer, it should be taken for granted that you prioritize your Clients and do your best to guide your Clients to the appropriate solution you regard as best based on your expertise and experience. In addition to this, our firm particularly focuses on the following strengths in approaching our tasks.

  • cllient oriented serviceeClient Based Service

    Due to the specialization and division of labor in business, most of our Clients suffer from shortage of manpower and heavy workload hard to handle within the supposed worktime. If they only knew whom they should make the first call to for practicable advice, they would have reached out to us before becoming lost in judgment. We also heard that some Clients are reluctant to come to lawyers for advice, because they feel lawyers make only textbook advice based on law, not minding the real business of Clients.

    OKA FORTUNA Law is Client-oriented lawfirm that provides legal services in a flexible manner. In our daily services, we endeavor to provide legal support tailored to the actual situation Client is facing at and address to their needs and requests, by building mutual trust relationship (such as by concluding a legal advisory service contract that will enable us to provide Clients with legal advice at discount rate in their daily business. This will supplement the role of Client’s legal department.) We are aware that the issue be solved for the benefit of Client, and will not suggest superficial “textbook” solution that is impracticable to apply.
