A power of attorney ("Ininjyo" in Japanese) gives a 3rd party the authority to act on your behalf. As per Japan export regulations it is necessary however the requirement is often waived. In local ports it is likely a signed "ininjyou" will be required in order to complete export customs clearance successfully.

Vacuum cleaners, used camping gear, antique furniture, golf clubs, footwear used on farms, car tires etc are items which are often checked and may cause problems. Refer to each country's relevant customs authority for complete details and restrictions.
