Apple is working hard to ensure Japanese car makers have iPod connectivity systems available for music loving drivers.

The company today revealed that Nissan, Mazda and Daihatsu in Japan have joined BMW, Mini, smart and Alfa Romeo in Japan to deliver iPod integration with their car stereos for 2006 model lines.

“We’re delighted to have such a wide variety of car companies in Japan offering iPod integration,” said Greg Joswiak, Apple’s vice president of worldwide iPod product marketing.

“iPod is the number one digital music player in Japan and more music lovers than ever can now enjoy a seamless iPod music experience in their car.”

A selection of third party products also exist for cars that lack such built-in integration.
