Since nobody has confirmed if that one is compatible with an HHKB, I'd rather advise you to buy an official rooftop from here

Looks far better, no "Orange" on it and is official.

kissuI have one of these and I use it to cover a keyboard with an HHKB layout no problem. If the "orange" logo is no big deal for you, this is a great deal, and the product is high quality. I bought another one in a different size to cover a TKL. Though it's better to buy on Aliexpress or KPRepublic, since the shipping is much quicker than it is on here.
