Delays in mail delivery in the United States of America and Great Britain
The designated postal operators of the United States of America and Great Britain informed us that there may be delays in mail delivery in the Mid-Atlantic and Northeastern areas of the United States and throughout Great Britain due to a cold wave. In addition, there may also be delays in delivery in other areas of North America and Europe because of the impact of the cold wave.
Furthermore, there may also be considerable delays in delivery of mail sent to Japan from the Mid-Atlantic and Northeastern areas of the United States of America and Great Britain.
Thank you for your kind understanding and cooperation with this situation.
