Firstly is our ability to handle multilingual affairs. Since the opening of our firm in 1984, we’ve overcome language barriers to provide international legal services by collaborating with foreign experts versed in common law and French jurisdictions.

Secondly, it is our ability to deliver all-rounded services. At present, it is necessary for clients to base their choice of lawyer not solely on price comparison, but on the quality of its services. Our firm is dedicated to providing total services to obtain client satisfaction by treating each case from a broad perspective, not just from a narrow legal perspective.

Based on these policies, we envisage longevity in our firm’s business for 100, or even 200 years . If we can be of any assistance to you, please feel free to contact us. We will ensure that you are satisfied with our services.

Message from Partner on Common Issues for Individuals

A person can insidiously get into international legal trouble. As international society is immature with regards to legal procedures, even if we obtain a court ruling in Japan, it is sometimes not enforceable in foreign countries—and vice versa. That’s why, especially in the case of international marriages, many people feel as if they experienced two marriages and two divorces, along with the extra legal problems associated with that. The same goes for succession.

If your child is married to someone of a different nationality, you might purchase real estate in a foreign country with the object of creating wealth for your child’s future. In such cases, legal problems might arise, such as disputes with neighbours or third parties, or even situations in which the persons or companies managing your property take possession of your real estate.

Also, if the land that has been your family’s for generations is inherited by one of your non-Japanese relatives, this sole fact could prevent you from selling or impignorating it. Even with regards to bank accounts, which are normally considered to be high liquidity assets similar to cash, can never be refunded without any official documents. Therefore it is impossible to get a refund without the involvement of international lawyers.

As a result of dealing with many kinds of cases in several languages, we are able to provide legal services in a broad range of fields to individuals as their home lawyer.
