Service Delays Expected in Japan
Service Update
Updated Thursday, March 17, 2011
Our thoughts are with all the people affected by the earthquake and tsunami.
Service delays can be expected in parts of Japan after a major earthquake, followed by a Tsunami, hit the country on Friday, March 11.
Due to extensive damage to the transportation infrastructure, please note temporary service suspension in Northern Japan.
UPS has resumed its pick-up and delivery services in Eastern Japan, however some delays can be expected. In addition, the UPS Service Guarantee has been suspended for these affected areas. Please contact your local Customer Service Representative for more information.
UPS Japan will continue to do its utmost to ensure packages reach their final destinations as rapidly as possible.
UPS is monitoring the situation and will provide further updates as necessary. Please check this website for regular updates.
As our Customer Service Centre in Japan is experiencing high call volume, we would like to urge customers in Western Japan who wish to Schedule a Pickup to do so via our website to avoid further delays.
If you are trying to ship something (as in emergency supplies overnight delivery type of thing) to Japan UPS is not taking rush packages. Not sure if that is only parts of Japan or what.
