The iPhone has 72% of Japan's smartphone market

"Apple Inc.’s iPhone shipments to Japan more than doubled in the past year, capturing 72 percent of the country’s smartphone market, a research firm said.
Shipments of the iPhone, which began selling in Japan in July 2008, climbed to 1.69 million units in the year ended March 31, Tokyo-based MM Research Institute Ltd. said in a report yesterday. That raised the total to 2.3 million, Hideaki Yokota, an analyst at the research firm, said by telephone today.
The iPhone helped smartphone sales more than double last fiscal year in Japan as shipments of regular mobile phones shrank, according to the report. Smartphone shipments will probably exceed 3 million units in the 12 months started April 1, even as the overall market is forecast to contract for a third year, it said.
“Last year was just the beginning of the smartphone competition, which is why Apple did so well,” said Calvin Huang, who rates iPhone assembler Hon Hai Precision Industry Co. “buy” at Daiwa Securities Group Inc. in Taipei. “This year will be much more competitive.”"
