In her first declaration, Kaoru explained that her son Koki disappeared in the park:

I brought Koki to the park after he came back from school shortly after 3 p.m. He went missing while I was in a restroom that is about 20 meters away from large play equipment in the athletic playground area of the park.

The police conducted a search using the GPS in Koki's cellphone—which also has the strap that the police think is the crime weapon—finally finding the body, which the mother refused to see. After further questioning, she admitted she was the killer. [Mainichi and Yomiuri via TokyoMango]

The portable subway strap is designed to show female passengers that your hands are occupied —thereby reducing your chances of being falsely accused of groping. Apparently, the 525 yen ($5) product has proven quite popular with commuters. Although the train above seems to have a much more awkward situation brewing. [Product Page via Pink Tentacle]

For about $9, you can get your own bra or panties to attach to your cellphone. It's just a gimmick, and it's tiny, so it's probably the only lingerie your wife will permit you to have that doesn't belong to her. Unless, of course, you've been fucking a midget on the side. – Jason Chen

Most of these phones are Japanese, but we do see a couple RAZRs and possibly some Sony Ericssons in there too. All of them actually slide and flip—just like the real thing. No real point here; they just look cool. – Jason Chen

It's a miniature chalkboard complete with chalk and eraser so you can doodle or write little notes to yourself while you're out. Need to take down a number? Write it on the chalkboard. Just be careful when you put it into your pants or you'll have a pocketful of chalk and no date for the weekend. Sounds like all four years of high school and parts of college for us. – Jason Chen

Unfortunately, the only phones that can be charged with this thing are from FOMA and SoftBank—both only available in Japan—but we're sure somebody can come up with something similar for US phones. Get to work, crazies! – Jason Chen

Beyond just being fun for the whole family, dying the straps will make it easy to tell which one your kids' friends slobbered all over and which one you keep in a drawer just for you. And at $4 each, it's pretty cheap as well. Then again, if just having a Wii isn't getting your wife into gaming, perhaps you've got no hope after all. – Jason Chen

You can buy different amounts of beads depending on your needs—but get enough and you can have a Japanese Mardis Gras anywhere. Politely asking women to take off their tops is how they do it. – Jason Chen

Essentially a giant mood ring, the Aura Monitor changes between eight different colors depending on your mood. So yes, it's just as useless. But it does look pretty cool as a cellphone strap. – Jason Chen

The other feature, if cellphone straps could have features, is that the strap detaches and separates into a pendant and that other part. The non-pendant part. We'll stick to poop. – Jason Chen

Hell, if you can carry a gun this way, why not a cellphone? We certainly can't think of a reason why not. – Jason Chen

In the picture above, the new straps with their rounded plastic nubs on the ends are lined up on the left, and the old one whose business end vaguely resembles the Nintendo Wii console is on the right. Get the new ones, butterfingers! Or, you could just hold on tighter to the damn controller. Heck, Babe Ruth never let his bat fly out of his hands, did he? Huh? Just an example. – Charlie White

The New, New Wii Strap [Kotaku]

A guy put 25 pounds of books, a 100 fl. oz. case of laundry detergent, and a 2.5 gallon water jug on a sling suspended only by a Wii strap and it held just fine. After he added the jug, the contraption flipped and smacked him in the face. Wii strap still intact.

What finally did the strap in was him holding the Wiimote in one hand and the strap in the other, pulling and heaving so hard that he started to shake. This process finally made the strap break off.

Conclusion: regular usage shouldn't break the strap. Advice: don't swing the Wiimote around like goddamn David of Goliath fame. – Jason Chen

Well, you're in luck, boys. Some weirdos at Strap-ya did some research on the Top 20 most trendy, popular school girl uniforms in Japan and made them into cell phone straps.
