Global Lessons from Mobile Computing in Japan
We recently spent a fascinating hour with James Gosling, godfather of Java and an eloquent supporter of open standards and common sense when it comes to mobile application development. James points out that NTT DoCoMo has let anyone drop software into the network and get paid. But North American carriers don’t appear to have taken the hint. “[They] have this attitude that their networks need to be closed. Personally, I don’t buy it. They’re being very, very short-sighted.” Mobile business developers and service planners everywhere: Don’t miss this one.
We spent a day at Sun Microsystem’s JavaOne conference and show in Yokohama in September, and were pleasantly surprised to meet up with mobile software vendor Openwave, grand-daddy of the WAP Forum (freshly repainted as the Open Mobile Alliance). Japanese carriers have created killer Java services… and they had to do so from scratch. That included the provisioning system which actually feeds the applis onto the handsets (providers merely have to write the downloadable Java code). Now another major player has launched a Java provisioning system (which also works for other content). Want to launch Java, but you’re not partnered with DoCoMo? You’d better watch this one twice…
By platform, mobile games (mostly Java, as far as we could see) represented 9.2 percent of the 393 new titles announced at the TGS, a significant if yet modest chunk of the overall game market. This was up steeply from 4.1 percent of 339 titles at the fall 2001 show, but still not equal to the 11.0, 14.7, and 17.1 percent shares seen at the spring 2001 (309 new titles), fall 2000 (334 new titles), and spring 2000 (380 new titles) shows, respectively. We have lots of Java screen savers,” said Taito Corporation at the DoCoMo booth; Seoul-based game maker GameVIL comes ashore to leverage made-in-Korea BREW expertise (KTF’s BREW allows 200KB downloads — the standard for KDDI to beat?); and advice on creating successful Java services from PCCW: “Prepare a good environment for the developers.” Daniel had a splitting headache, but this program rocks! 
WWJ has been focusing on mobile Java for the past few weeks — and with good reason. The pundits claim the interactivity and secure mobile execution environment provided by Java could be vital for making 3G data services pay off sooner rather than later. We visited then-pre-IPO software developer Net Village, creator of the “Remote Mail” Java-based mail appli. A couple of key facts emerged: Java boosts packet revenue for the carriers, the cost and complexity of deploying sophisticated Java applis may be beyond what the carriers themselves can do (economically), and Remote Mail is one cool app — 330,000 happy users can’t all be wrong! (See a live demo.) Oh — and NV’s IPO generated a modest 4.094 billion yen.
Java continues to be one of mobile Japan’s little-told success stories. We drop by J-Phone/Vodafone to find out who’s using Java, how “applis” are loaded onto the portal, and how “desktop” applications function. Already, Java content providers are focusing on the desktop appli as a way to capture and maintain new subscribers, since the always-on functionality tends to drive loyalty. We also get a live demo of downloading and running Java games. There’s an ecosystem brewing here, and the aroma is pure success. Wireless marketing heads everywhere: Pay Attention! 
There’s been endless yakking about cultural differences between Japanese and US keitai users. Which features appeal to which culture? Is wireless Internet important for Americans? Those Japanese will pay for data, won’t they? Yada yada yada… We’ve heard comments ad nauseam about the differences between Americans, Europeans, and Japanese when it comes to choosing cell phones. While we have long disbelieved the odious stereotypes — like “Japanese want to pay for Internet access” and “American thumbs are too big for those tiny i-mode keypads” — we have to admit, we weren’t sure what to believe ourselves. WWJ gets to the heart of the matter with a visit to Cellular Plaza Mims, a unique cell phone shop serving large numbers of true-blue Americans here in Japan. 
This week, Wireless Watch Japan ( WWJ ) was invited by NTT DoCoMo to visit their Club D Showroom, located on the 29th floor of corporate HQ in Tokyo. We do the intro from the FOMA F1 — that’s the race car that can communicate at 384 Kbps on a test track using FOMA, we play with 504i Java and 251i i-shot handsets and tried videoconferencing with the new 3G PDA by Sharp. This programme is pure eye-candy, and is not-to-be missed for the serious 3G wireless aficionado. Boy-o-boy-o-boy… it doesn’t get much better than this folks! After buying a soda via c-mode, we ask, “Why does DoCoMo spend so big to promote its technology?” 
There’s a tremendous amount of initial wireless LAN network activity going on in Japan right now, but it’s still too early to say how WLAN will affect 3G. One thing is certain however: licensed-spectrum carriers are looking closely at WLAN to determine whether the technology will disrupt their carefully knit 3G network, wireless Internet, and data revenue plans. We speak with an industry insider on a recent WLAN hotspot trial conducted by a major mobile telco. But large carriers and others thinking about launching hotspot networks shouldn’t worry about finding content. First, solve the billing, roaming, and security problems — then content providers will beat a path to your door… just as happened with, oh…, for example, i-mode. 
G-mode was set up in 2001 for the sole purpose of creating Java games for wireless. They say they’ve sold 63 million downloads since then, and their games are played 250,000 times per day. This is the first mobile content provider we’ve ever met that claims made-in-Japan games can be exported overseas, despite the barriers of language and culture. Considering that Tetris — known globally — has no text, they just could be right. 
With over 150 different Internet-capable cellular handsets in use by four different carriers, the challenge of formatting content to match the terminal is becoming, well, terminal. Each model has its own screen dimensions, color capability, and other idiosyncrasies, and if your business depends on making sure that mobile shoppers can see pics of all your products, like, say Yahoo Japan Auctions’ does, you’re in a world of hurt. Fortunately, one company has a solution. Thank God for the Americans!
