The same survey was done in July of 2007 and at that time almost 10 percent of those polled said they would buy the phone if their carrier made it available so it appears demand is somewhat down.
iSHARE did not have exact reasons for the low demand but did note that SoftBank is third in subscriber base and only 23 percent of those polled were current SoftBank users. NTT DoCoMo is the clear leader at almost 40 percent, but they do not hold an iPhone distribution contract.
77 percent also noted that they prefer a removable battery, something Apple refuses to do with their media devices. The largest hurdle will most likely be that the iPhone does not bring anything the Japanese have not seen already. 3G is standard on Japanese networks for both calls and data services and most new phones have Japan-only 1Seg digital TV and high resolutions such as 800x480. The iPhone will have neither when it launches.
