Think outdoor neon light shows, and Las Vegas and New York's Times Square comes to mind, right? They're great--but the displays in Japan are even more intense. Tokyo usually gets the nod for best neon, but I beg to differ--Osaka and the Kansai region has it beat.
For proof, please check out this video postcard from Osaka, starting in the Dotonbori district, and see if you don't agree.
