Introduction of our office
KASAI Law Office was founded on the principle of “Making Lawyers More Accessible! “
We would like to help people who feel uncomfortable talking to a lawyer, or who wonder if it is appropriate to discuss such matters with us. First of all, please tell us your story.
【Introduction of our firm】
Law firms are generally located close to the courthouse for the convenience of attorneys, but our office is only a two-minute walk from Hisaya-odori Station on the Meijo and Sakuradori subway lines, making it easily accessible for our clients.
【The Thoughts of a Lead Lawyer 】
I have lived all over Japan due to my father’s job transfers since I was a child.
In addition, I have work experience at a business corporation after graduating from university, and I strive to provide advice that is not only based on theory but also applicable to real life.
Many people feel hesitant to consult with a lawyer. They may wonder if it is appropriate to consult with a lawyer about certain issues. I want to eliminate the threshold that exists for lawyers like that.
There are many people who are troubled by the idea of consulting a lawyer. I hope that you will consider consulting with us before feeling burdened by your worries.
【Features of our firm】
(1)Careful interviews
We will not only be directly involved in the case, but we will also listen to the background of the case in detail to accurately grasp the facts. We will then establish a policy that is not based on stereotypes, but takes into consideration the feelings of the client.
(2)Collaboration with various professionals
We can provide legal services that incorporate specialized knowledge through collaborations with professionals such as certified tax accountants, architects, judicial scriveners (Shiho-shoshi), and medical doctors.
(3)Trust between lawyer and client
We will report to you as appropriate so that the client does not feel anxious about the case. We will also meet with you as many times as necessary after your request until you are satisfied with the results.
