Roughly 100 eager customers lined up in front of a Japanese Apple Store today to get their hands on the company's new iPod touch, signaling high demand for the portable player in that region. AV Watch reports that the iPod touch went on sale today and that the first man in line to purchase the device arrived as early as 1:30 a.m. local time. The 10:00 a.m. opening saw around 100 people waiting for their units, suggesting a high possibility of iPod touch selling out in Japan as well as China. Apple introduced the iPhone-like portable player in two versions on September 5th during a special event in San Francisco, pricing an 8GB model at $300 and another 16GB model at $400. The Apple Store in Ginza, Japan is charging customers around $315 for the 8GB version and $420 for the 16GB device.
