It's official: Japanese cellco Softbank will offer Apple's iPhone, the company said today. Like all the other carriers who've announced they'll begin selling the handset, Softbank said the iPhone would be added to its network "later this year", news agency Reuters reports. Expect it sooner rather than later. Certainly, World+ …
Confirmation of 3g
Consider that concrete evidence of 3g - I just got back from Japan, and a 2g iphone doesn't work there at all as the phone network is different.
I think iphone will do really well in japan - the japanese phones are really big and clunky, and look really crap to use. About the opposite of what you'd expect really!
likely to retain exclusivity
Softbank, which used to be Vodafone, is the only fully GSM operator in Japan and so the only one which could offer a 2G iPhone, or support 2G fallback for a 3G device. DoCoMo do use the GSM family WCDMA so in theory could use a 3G iPhone, but it would have no 2G fallback without a huge amount of expensive and otherwise useless hardware work from Apple.
So in all likelihood the deal will be exclusive in Japan, regardless of Apple's rethink of its business strategy to go for multiple carriers competing to write the shortest press release.
Who is right?
The first two comments seem to completely contradict each other?
(and this isn't even an Apple v Microsoft/PS3 v Xbox fanboy war comments page!)
GSM in Japan
There's no GSM in Japan, but both DoCoMo and Softbank are using 3G (W-CDMA). So, this is it, first official confirmation of a 3G iphone!
AC is Correct
There is absolutely no 'real' GSM coverage in Japan outside some handset manufacturers test beds and some Pico-cell usage for some international offices I believe.
Most 2G/2.5G networks out there use a Japanese standard system called PDC or the slightly more popular globally, CDMA. Any 3G network uses a variant of W-CDMA )sometimes referred to as FOMA I believe).
Softbank operate a PDC (1.5GHz) and W-CDMA (2GHz) network, yet the majority of handsets they offer are Dual Mode GSM/W-CDMA for the international roamers.
If Softbank are offering the IPhone, they will therefore be offering a Dual Mode, GSM/W-CDMA model, which essentially confirms what every man and his dog already knows.

No GSM in Japan => people just don't get it
I have been living in Japan since the early 90s and I am working in the telco industry. I have been telling folks that there is no GSM in Japan for at least 15 years and it has always puzzled me how stubbornly stupid non-residents are when it comes to accepting this fact.
I have been sitting next to middle and upper management folks from the world's leading companies on long haul flights from Europe and elsewhere to Japan. It's always the same pattern. We would be talking about what we do for a living, we would exchange business cards, they would recognise that I am a resident in Japan and that I work in the field of mobile telephony, that I probably know what I am talking about when tell them that their GSM phone will not work when we land, that there was no GSM network in Japan, that the way the spectrum was cluttered had made it impossible for Japan to adopt GSM even when they finally intended to do so in 1997.
And what do these folks ALWAYS do first thing when stepping out of the airplane in Narita? They turn their GSM mobiles on and express surprise that it doesn't work. I would say "I told you there is no GSM in Japan". Many of them still don't believe it and utter something like "Maybe there is coverage once I get into downtown Tokyo". No! There won't be!
How can people be so f****ing stupid??? It's flabbergasting. What part of "There is no GSM in Japan" do they not get???
Today, there are five different mobile telephony standards in use in Japan: 1) the old NTT proprietary 2G system called PDC (still operated by DoCoMo), 2) the Japanese open standard PHS system (operated by Willcom) originally developed in rivalry to GSM and used in various other countries, 3) a modified and incompatible version of Qualcomm's CDMA-One, often called J-CDMA (now being phased out), 4) a CDMA2000 overlay on the J-CDMA system (operated by KDDI), 5) W-CDMA (operated by DoCoMo and Softbank). None of these is compatible with GSM and there never was any GSM either.
Before Softbank acquired Vodafone Japan, they intended to build and operate a network using yet another different standard, the Chinese TD-SCDMA.
3G technologies are easier to introduce in Japan because the spectrum is mostly still unused. GSM requires two bands (uplink and downlink) of contiguous bandwidth with a given fixed space between uplink and downlink. The frequencies on which GSM operates are simply not available in Japan and even if you wanted to make space for them, it would have a domino effect on just about everything else, including emergency services. If you wanted to make space in the GSM uplink band, not only would you need to move various emergency services and the Citizen Band band but you would also have to move the downlink band of the PDC and the J-CDMA system, which would require the uplink bands of those also to be moved, which would require yet other applications to be moved. The Japanese spectrum between 800 and 1000 MHz is a total mess, like a Swiss cheese. Tthe Japanese PDC and J-CDMA systems do not have contiguous spectrum, they use various bits and pieces all over the spectrum. This is the main reason why J-CDMA is incompatible with CDMA-One. They simply couldn't fit the bands in without messing up everything else. Likewise, there is no way they could fit in GSM850 or GSM900.
The situation in the Japanese 1800 MHz band is even worse. This is used for local applications such as telemetry. There are tens of thousands of license holders all over the band, all holding a tiny slice in the place they are, go to a different location and somebody else has a license to that same slice there. Any prospective mobile telephone operator who wanted to operate a GSM1800 network nation wide would have to move off tens of thousands of license holders and compensate them. Even if they have the money, just think of the time it would take to vacate the spectrum when you have to negotiate with so many parties. Why would you want to do that if you can get still unused spectrum above 2GHz?!
The 1900 MHz band (for US GSM) is also unavailable, parts of it are used by PHS and parts are used by the Japanese 3G networks now.
That leaves only GSM450. With the introduction of digital TV and the shut down of analog TV in the near future it would theoretically be possible to use the then vacated 450 MHz band for GSM, but there are already many other parties interested in that spectrum for other applications and most GSM handsets don't even support the GSM450 band. GSM450 is only used in Russia. Not much of an incentive.
As you can see, there is very little chance Japan will ever get GSM. There is certainly no GSM now and there never has been.
FOMA is not a standard
FOMA is Docomo's brand name for their 3G service. It's not the name of a standard. Instead, Japanese marketing calls 3G "jiseidai" which means "next generation". Techies use the terms "W-CDMA" and "CDMA2000".
Japanese narrowband CDMA not compatible with US narrowband CDMA either
@ Gareth Davies
two slight errors in your post ...
The "more popular globally CDMA" you refer to is the US narrowband CDMA system called CDMA-One which is not compatible with the Japanese narrowband CDMA system which is called J-CDMA. KDDI who use J-CDMA used to print the Qualcomm CDMA-One logo onto their handsets because both technologies are based on Qualcomm protocols and chipsets, but the global CDMA-One system has a single contiguous pair of uplink/downlink bands with fixed spacing, while the Japanese had to fit this into available holes in their spectrum so they use several smaller band pairs with variable spacing and even the order of uplink and downlink is reversed. As a result, the two systems are not compatible, you need a dual mode J-CDMA/CDMA-One handset to roam between the two.
Further, not all the 3G networks in Japan use W-CDMA, Docomo and Softbank do, KDDI doesn't, they use CDMA2000 instead.
