===HHKB Professional<ref>PFU website - [http://www.pfu.fujitsu.com/hhkeyboard/whatsnew.html#news2003 Happy Hacking Professional series released (Japanese only)]</ref>===
The layout of the professional carries on the tradition of the ANSI layout with the inverted trapezoid shape for the modifiers versus the alphanumeric keys. It was the first keyboard by PFU to be introduced with [[Topre|Topre switches]] (electrostatic capacitive non-contact technology<ref>PFU website - [http://www.pfu.fujitsu.com/hhkeyboard/new030424.pdf HHKB Professional leaflet (Japanese only)]</ref>) as opposed to rubber dome over membrane which was a feature in [[Happy Hacking Keyboard|Happy Hacking Keyboard]] as well as [[HHKB Lite|Happy Hacking Keyboard Lite]].

In addition to the use of Topre switches, Happy Hacking Keyboard Professional uses a [[USB|USB connector]]<ref>PFU website - [http://www.pfu.fujitsu.com/hhkeyboard/new030424.pdf Press release: Happy Hacking Professional (Japanese only)]</ref> which differs from [[PS/2|PS/2 connectivity]] on the Happy Hacking Keyboard Lite as well as the various connectivity that was offered on Happy Hacking Keyboard.

The white variant keyboard was priced at ¥25,000 (Japanese Yen) from PFU Direct<ref>PFU website - [http://www.pfu.fujitsu.com/hhkeyboard/new030424.pdf Press release: Happy Hacking Professional (Japanese only)]</ref>, whereas the charcoal gray variant was priced at ¥24,990 (Japanese Yen) from PFU Direct.<ref>PFU website - [http://www.pfu.fujitsu.com/hhkeyboard/new050214.pdf Press release: Happy Hacking Professional "INK" (Japanese only)]</ref>

The white variant series was introduced in April 24, 2003 and was discontinued at an unspecified date.<ref>PFU website - [http://www.pfu.fujitsu.com/hhkeyboard/whatsnew.html#news2003 Happy Hacking Professional series released (Japanese only)]</ref> The charcoal gray variant series was introduced in Feburary 14, 2005 and was discontinued at an unspecified date.<ref>PFU website - [http://www.pfu.fujitsu.com/hhkeyboard/whatsnew.html#news2005 Happy Hacking Professional "INK" series released (Japanese only)]</ref> However according to PFU Systems (formerly known as PFU America), the Happy Hacking Keyboard Professional range was discontinued on December 10, 2006, the same day as PFU Systems discontinued [[Happy Hacking Keyboard]].<ref>(Wayback machine) PFU Systems - [http://web.archive.org/web/20071018020213/http://www.pfusystems.com/hhkeyboard/spec.html Specifications]</ref> On the contrary, there has been no documentation pertaining the launch dates of let alone the price for Happy Hacking Keyboard Professional in the US. 

Charcoal gray variant was noted to be using sublimation technology on the keycaps.<ref>PFU website - [http://www.pfu.fujitsu.com/hhkeyboard/new050214.pdf Press release: Happy Hacking Professional "INK" (Japanese only)]</ref>
