2012财年日本平板电脑出货量为568万台，需注意的是，日本手机（包括智能手机和功能性手机）每年出货量是这一数字的5-6倍左右。

至于PC设备出货量，日本电子信息技术行业协会的数据则显示，日本PC出货量在同一时期为1115万台，同比下降1.1%。

MM Research预测2013年日本平板电脑出货量将增长至690万台，并在2015年达到950万台。也就是说，日本平板电脑出货量将在2年内超越PC，而在2010年之前，日本几乎不存在平板电脑市场。

1）Amazon Launches App Engagement Reports, Allowing Appstore Developers To Track App Usage & Revenue

Sarah Perez

Continuing to grow its suite of services aimed at mobile app developers, Amazon today announced App Engagement Reports, free app usage reports that are now a part of the company’s Mobile App Distribution Portal. The reports are designed for Amazon Appstore developers in need of information about app performance and revenue.

Specifically, the reports include daily and monthly active devices, installs, sessions, average revenue per device, and retention metrics, and they can be filtered by marketplace, viewed in chart form, or downloaded as a CSV, the company explains in this afternoon’s official announcement. Developers will also be able to change the data range on the reports in order to see historical trends.

There are six Engagement Reports now being provided:

■Overview: A summary of key usage data for your app or game

■Average Revenue: Daily and Monthly Average Revenue per Device (ARPD) and Average Revenue per Paid User (ARPPU) for In-App Items

■Retention: Daily Retention for days 1-3-7 and Weekly Retention for weeks 1-2-3

■Active Devices: Daily Active Devices (DAD), Monthly Active Devices (MAD), and Sticky Factor (DAD/MAD)

■Sessions: Total Daily Sessions and Average Sessions Per Device

App Installs: Daily Installs and Uninstalls

At launch, the reports are only available for those apps that were submitted and published after October 25, 2012. For developers who haven’t updated their apps since then, they’ll need to either republish the app or submit an update in order to activate the reporting feature. However, there’s no need to make any other changes to the app’s code or integrate any additional software.

The report will include data for apps running on Amazon devices like the Kindle Fire and Fire HD, as well as any other Android devices running the latest version of the Amazon Appstore mobile app.

App analytics and sales figures are crucial to making Amazon’s Appstore a more complete service – these things have long been standard features of competing stores like Google Play or

Apple’s iTunes, for example. Though many developers still integrate third-party SDKs to allow for increased capabilities and more detailed reporting beyond what comes out-of-the-box, it’s
expected for the Appstore itself to at least provide some sort of basic insight into an app’s traction and sales. Amazon says that reports have been a “popular request from developers,”
and that’s likely an understatement.（source：techcrunch）

4）Minecraft Creator’s New Game ‘Scrolls’ Gets A Trailer, Arrives June 3 In Beta

Darrell Etherington

Mojang, the creative force behind Minecraft, is releasing its next title to the public a week from today on June 3rd. The new game, called Scrolls, is a digital collectible card game, similar in concept to Magic: The Gathering, and therefore a very different beast from the free-form world-building and exploration sim Minecraft. Like Minecraft, it’ll allow users to access the software very early, inviting them to become a key part of the development process. But can lightning strike twice for Mojang?

Minecraft is an unbridled success, by virtually every measure. At I/O, the Play team revealed that it plays a game called “Where’s Minecraft?” which has them find the title in the top grossing list. It’s always near the top, which is a remarkable exception for a game that offers a straightforward, one-time purchase pricing scheme; free-to-play titles rule the charts these days. The mobile version has sold over 10 million copies, Mojang says, and revenue is up well past $100 million at this point.

Scrolls has been in development for a few years now, and after Mojang and Bethesda settled a lawsuit over the name last year, it’s now ready for a public release. It’s hard to imagine

Scrolls putting up Minecraft numbers – it’s hard to imagine anything putting up Minecraft numbers – but there’s no question all eyes will be on Scrolls when it drops next week, and the trailer definitely shows something that looks like it could be very addictive fodder for gamers.（source：techcrunch）

5）A Quick Look At Japan’s Market For Tablets

by Dr. Serkan Toto

Tokyo-based MM Research Institute has released a few interesting stats on the Japanese market for tablets I thought are interesting to share (phones aren’t the only mobile devices people over here use to play games, after all).

According to the company, the number of tablets shipped domestically grew 104.3% in fiscal 2012 from fiscal 2011 (ending in March). And within that market, Apple was the No. 1 maker for a third straight year.

Total tablet shipments in fiscal 2012 in Japan stood at 5.68 million units. Growth accelerated in the second half of the year:

So 5.68 million tablets were shipped in Japan in 2012: is this a strong or weak number?

For context, the number of phones (feature phones and smartphones combined) in  Japan each year is about 5-6 times higher.

More relevant is the comparison to PCs: last month, the Japan Electronics and Information Technology Industries Association reported that PC shipments in this country dropped 1.1% on the year to 11.15 million units – despite the launch of Windows 8 in October 2012, the biggest worldwide (Japanese buyers could choose between over 250 Windows 8-powered devices on the weekend of the launch).

MM Research projects the number of tablet shipments to increase to 6.9 million units in 2013 and reach 9.5 million in fiscal 2015, as can be seen in the chart above.

In other words, the inflection point tablets > PCs is expected in about 2 years – and the market for tablets was essentially non-existent before 2010.

Apple clearly dominates Japan’s tablet market

Apple Japan managed to ship a total 2.98 million iPads and iPad Minis in 2012, reaching a 52.5% market share.

MM Research says that Asus, thanks to the introduction of Google’s Nexus 7 in 2012, was second:

Android is catching up quickly

In terms of tablet OS, MM Research sees Apple ahead with 52.5% market share in 2012 (see above), while Android reached 42.4% (2.41 million units combined).

Other OS, with 5.1% (290,000 units), are not really relevant in Japan currently.

It’s interesting to see Android gaining ground very quickly on the Japanese tablet market.（source：serkantoto）
