April Fool's Day doesn't have very deep roots in Japanese culture, but obviously branding creatives and open-minded corporations are seeing the potential benefits of making potential customers laugh. Rather than pulling a fast one, these pranks put their silliness up-front and center.

Introducing the iKA Organic Ebook from publisher Kodansha. Drawing its power from the squid's natural bioenergy, there's no need to recharge the batteries. The iKA's long tentacles serve as a handy neck-strap, it glows in the dark and has endless supply of ink. The iKA is provided via a subscription service, which delivers a fresh squid each week (note:  size and weight may vary). You get the added bonus of being able to cook and eat the old one (special squid dish recipe available to early buyers!). How's that for eco-friendly technology?

Don't you hate how unwieldy pizzas can be? Dominos's new canned pizza is not only compact, it's long-lasting, so you can stock up your bomb shelter and never go without a slice!
