I am a partner lawyer in Ogawa Law Office which is located near Yotsuya station, around Shinjuku.

My clients include international companies, startup companies and individuals. I have extensive experience in the area of family law (such as divorce, inheritance and wills, including international cases), tort law (such as traffic accidents or defamation), Internet-related caseslabor law casescontract law (including preparing contracts in English), and corporate law cases.

We, the members of Ogawa Law Office, are the professional litigators. One of the advantages of litigators is that they know what happens in the lawsuits and therefore, are able to give proper advice in preparing contracts or business scheme in terms of preventing disputes.

Legal service is like a service provided by a doctor. The sooner you look for legal advice, the chances are that you can solve the problem better and easier. We can be of your help.
