I'm not sure why anyone would pay US$4240 for a blank keyboard (when you can get one for US$90), but since this is Japan we're talking about here, the question is clearly rhetorical.

According to CNET Asia's Mobile Ojisan, the Happy Hacking Keyboard Professional HG Japan (love the name!) is the product of a collaboration between Fujitsu PFU and Daitetsu-Yatsui Urushi Workshop, the latter a traditional lacquerware maker. Each key is handpainted with 10 coats of Japanese lacquer, then sprinkled with gold dust.

As it happens, I find lacquerware irresistibly beautiful, but to find it on something as… disposable as a computer keyboard just seems so wrong.

The keyboard is only available in Japan, and is made to order.
