Introduction of Websites for Searching Japanese Court Rulings

We often receive inquiries, from overseas counsels and clients, such as: “Since Japanese court rulings are published in Japanese, there is no means of knowing the details. Is there any means of retrieving them at least in English?”.
In response to such demands, Japanese courts, including the IP High Court, are offering websites that allow you to retrieve Japanese court rulings in English, though they are not exhaustive. We will introduce the address information on such English websites, along with the address information on Japanese websites, as below. We hope that this will be helpful to you.
