オセアン居留地法律事務所

オセアンとは、フランス語で海を意味します。
海は、どこまでも深くどこまでも広く際限がありません。

そんな海のような無限の可能性を事務所にもたらせるとの気概を込めて名付けました。







Origin of the Firm’s Name

“Océan” means “sea” in French. The sea is infinitely deep and endlessly vast, without boundaries. We chose this name with the aspiration that our firm, too, will embody the boundless potential of the sea and continue to bring limitless possibilities into our practice.

代表者メッセージ

トラブルに直面された時、
人生の荒波を乗り越えるまでには、抱えきれない程のご不安や悲しみ、時には怒りもあるでしょう。
トラブル解決に至るその日まで、
雨の日も風の日も時化の日も、平穏な日々を目指して、
荒波を乗り越えるお供をいたします。





When you are confronted with difficulties, the stormy seas of life may bring overwhelming anxiety, sorrow, and at times even anger.
Until the day your troubles are resolved, we will stand by your side—through rainy days, through strong winds, and even through rough seas—always striving toward the calm and peaceful days that lie ahead.
