Japanese used vehicle exporting is a large global business, as rigorous road tests and high depreciation make such vehicles worth very little (in Japan) after six years, and strict environmental laws make vehicle disposal expensive. Consequently, it is profitable to export them to other countries with left-hand traffic, such as Australia, New Zealand, the Republic of Ireland, the United Kingdom, Malta, South Africa, Kenya, Uganda, Zambia, Mozambique, Malaysia, Bangladesh and Cyprus. Some have even been exported to countries such as Peru, Paraguay, Russia, Mongolia, Yemen, Burma, Canada, and the United Arab Emirates, despite the fact that these countries drive on the right. It is actually "because" of these vehicles' RHD configuration that many of them are sent to LHD countries in the first place, for use as mail delivery vehicles. Many Japanese market Jeep Cherokees, for example, have found new use with rural mail carriers in the United States.
