KDDI's HTC J One announced in Japan, boasts microSD card support up to 64GB

The HTC J One comes equipped with the features that make the HTC One such a sought-after handset. There’s HTC BlinkFeed, HTC Zoe, the UltraPixel camera, the use of Android Jelly Bean as the operating system, and more.
Based on the information found in the official press release, it appears that the HTC J One will be shipped with a free set of accessories, some of which may prove useful (such as the HTC J One mini) somewhere down the line.
Anyway, something else that it will have is support for microSD card storage, and it supports up to 64GB microSDXC cards right out of the box. This should help make things easier when it comes to managing stored data on the device itself. The rest is just combined hardware and software.
To help you recap on more of the HTC One’s standard features, KDDI put together the following promo video (it’s also worth watching because it highlights some new features that will be present in the camera):
