Ringtones go to the dogs in Japan
Only in Japan: Ringtones that only canine ears can detect.
Love dogs. Love the Japanese even more for their highly bizarre gizmos. No other country has consistently amused and amazed the world with its weird and wacked-out inventions. Try topping this latest idea: Ringtones audible only to dogs, from Tokyo-based interactive content provider Dwango (PDF in Japanese).
Lest you think it's an error in translation, Dwango describes the download service very clearly as Inu ni shika kikoenai chakushinon--which translates to "Ringtones only dogs can hear," according to CrunchGear. But since this is available specifically for DoCoMo's i-mode phones, only Japanese dogs need apply.
