IPhone fans lined up Friday as the water-resistant iPhone 7 and larger iPhone 7 Plus went on sale in Japan, promising to be the first of the popular smartphone series to allow mobile payments here.

More than 100 people were waiting at an Apple store in Tokyo's trendy Omotesando district for the new models, which some view as Apple's latest attempt to woo consumers in a market where it enjoys relatively large market share. The debut came amid concern that iPhone sales are leveling off globally.

"I've heard that the mobile payment system is good so I can't wait to use it," said Tokyo customer Tomoko Kumagai, referring to the wireless technology enabled by Apple's adoption of Sony's FeliCa chip.
