It looks like it’s going to be another hot summer here in Japan and as the country calls for voluntary power cuts to cope with post-March 11 shortages, the Japanese people are using their head to come up with eco-friendly ways of keeping cool.

And we mean literally using their head: net retailer Rare Mono Shop has started selling a baseball cap with a solar-powered fan built into it.

It’s called the Solar Fan-Embedded Hat and is avaliable in a total of 4 equally-embarassing colors. The fan is built into the visor of the cap and blows a cool breeze at the user’s face through a small hole. It can be purchased online from Rare Mono Shop and goes for 1260 yen (US $15.69).

While wearing the Solar Fan-Embedded Hat probably won’t make you look cool, it’ll certainly make you feel cool, and under the scorching summer sun that’s all that really matters, right?
