  • High quality service and reasonable fee arrangements

    High quality service and reasonable legal fees

    We deliver high quality legal services at a reasonable fee, made possible by eliminating inefficiency in our operations.

    Reasonable attorney fees

    High fees at major law firms are often the result of over-staffing cases with a partner lawyers and junior associate lawyers who contribute very little to the actual resolution of the case. At Kamimura Ohira & Mizuno, we provide top quality legal services at reasonable rates by assigning the minimum number staff sufficient for each case.

  • Excellent foreign language capability

    Legal services can be provided in English and Chinese

    Members of our attorneys are fluent and able to provide legal services in both English and Chinese.

    Negotiation can also be conducted in English and Chinese

    Although there is an increasing number of law firms able to provide foreign companies with legal services, in reality, there are very few Japanese attorneys capable of conducting negotiations in English or Chinese. Attorneys at Kamimura Ohira & Mizuno are competent in English and Chinese and dedicated to providing the best legal service to our foreign clients.

    High quality documentation in English and Chinese

    Our attorneys have experience working at major domestic and international law firms in Japan, as well as at law firms overseas and major investment banks, where business was routinely conducted, and documentation was prepared in English and/or Chinese.





  • In-depth understanding of business management

    We provide legal advice based upon a thorough understanding of our client’s business as a whole

  • Retainer fee free system

    Reduce costs by avoiding a monthly legal advisor retainer fee

    Unnecessary legal expenses are eliminated because we require no monthly retainer fee and charge attorney fees only when we are specifically requested to handle a case.

    No monthly retainer fee

    At most law firms, it is customary for clients to be required to pay a monthly legal advisor fee (between 50 and 300 thousand Japanese Yen per month) regardless of whether they have been provided service or not. At Kamimura Ohira & Mizuno, we believe that it is unreasonable to receive a fee from a client we are not actively serving, so we have eliminated the monthly retainer fee.

    Priority handling

    Clients who have registered in our Retainer Fee Free System benefit from priority handling of cases. Furthermore, clients who have paid an initial deposit benefit from top priority handling of cases.

    Legal services are provided by an attorney who specializes in corporate law

    While there are many law firms employing the retainer fee system, it is common that the assigned attorney is not familiar with corporate or international law and cannot handle the needs of corporate clients. At Kamimura Ohira & Mizuno, we provide attorneys who specialize in corporate and international law to best handle the needs of our corporate clients.

About us

Kamimura Ohira & Mizuno was founded in 2013 by the Managing Partner who has over a decade of experience providing legal services at major Japanese and international law firms. Our mission is to provide legal services of a quality comparable to that of major law firms to our clients at a reasonable cost.
