Oblon is making a donation to the 2026 Kumamoto Earthquake Relief Fund established by Kumamoto City to assist those affected by the recent earthquake and support the region’s relief and recovery efforts. We extend our deepest sympathies to the individuals and families who have lost loved ones, suffered injuries, or been displaced, and to all whose lives and communities have been affected by this disaster.
“Japan has been an important part of Oblon’s history and identity for decades,” noted Oblon’s Managing Partner Philippe Signore. “Through our Tokyo office and our longstanding relationships with Japanese companies, inventors, patent professionals, and colleagues, we have developed connections that extend well beyond our legal work. We have great respect for the people and communities of Japan and are grateful for the trust and friendship they have shown our firm over the years.”
We stand with the people of Kumamoto during this difficult time and hope our contribution will assist those in need as the region begins the process of recovery and rebuilding. We wish everyone affected strength, safety, and a swift recovery.
