Java on J-Phone: The Fine Grind of Mobile Computing

Java on J-Phone: The Fine Grind of Mobile ComputingJava 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!

Japan Mobile Trivia that'll Separate the Pros from the Wanna-bes

All of Japan’s carriers devote an extraordinary amount of time, effort, and resources to creating marketing and sale materials designed to entice customers, boost sales, and — let’s be frank — brag about their networks and handsets. The Big Five (NTT DoCoMo, KDDI/Au, J-Phone, DDI Pocket, and Tu-Ka) produce monthly full-color catalogs touting the latest in handsets, networks and data services, calling plans and discounts, and customer support services. DoCoMo also conveniently produces a quarterly compendium of their monthly issues in English, while KDDI makes their calling plans and discount options widely available in English, Korean, Chinese, and several other languages. We combed through several carrier brochures and extracted some gems of info that are rarely if ever mentioned by English-language press, but that help to illustrate the depth and scope of the wireless business here. Without further ado, herewith we present WWJ’s first quarterly Review of Japan Keitai Trivia. Rabid Japan wireless devotees (and you know who you are) won’t want to miss this.

WLAN: Lessons from i-mode

WLAN: Lessons from i-modeThere’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.

When Japanese Carriers Buy Content

At lunch today, I almost choked on my okonomiyaki. But it wasn’t the fried noodles, vegetables, bits of squid, or pancake-like dough that comprise this Hiroshima delicacy (only rarely reproduced with any satisfaction in the Tokyo area) that caused my trouble; it was an involuntary reaction to my lunch-mate’s comment that DoCoMo looks like it’s becoming “a media company.” Whew!! Regular readers of this newsmagazine will know that one of my themesin the past couple of issues has been how Big D is morphing from an engineering-centric technology company into a media player, just like one-time ISP AOL has.

Standards-based Apps Rule, Except…

Getting a handle on the big & little pictureOpenwave is one of the key players in software and all things wireless, and are a vendor to both J-Phone and KDDI. We interview a senior product manager on standards-based applications, and why MMS may fail like WAP 1.0. We also take a first-hand look at a lively new instant messaging application for keitai and PC.

Why is J-Phone hurting so bad?

The drop in ARPU could be related to the fact that both DoCoMo and KDDI now have camera-equipped keitais on the market (although DoCoMo’s isn’t Java-enabled). Are we seeing the end of the camera-phone bubble? If so, there’s little else on the horizon to serve as the next market booster — except, of course, 3G speed-optimized services (and KDDI’s got the better network right now).
