In response to the Japanese government's declaration of a state of emergency, we are adjusting our operations accordingly.

At this point, we are currently moving most of our patent attorneys and staff in our main Osaka office to remote telework.
Our Tokyo office has already been transitioned to telework, whereas our Hiroshima office is doing business as usual.

Overall, we can continue to meet the needs of our clients without interruption.
Each of us can be reached by email though some at home may not be reached by phone.

We would appreciate your understanding and will remain focused on our clients to maintain our standards for prompt, high quality services during this difficult time.
