HHKB Professional[1]

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 switches (electrostatic capacitive non-contact technology[2]) as opposed to rubber dome over membrane which was a feature in Happy Hacking Keyboard as well as Happy Hacking Keyboard Lite.

In addition to the use of Topre switches, Happy Hacking Keyboard Professional uses a USB connector[3] which differs from 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[4], whereas the charcoal gray variant was priced at ¥24,990 (Japanese Yen) from PFU Direct.[5]

The white variant series was introduced in April 24, 2003 and was discontinued at an unspecified date.[6] The charcoal gray variant series was introduced in Feburary 14, 2005 and was discontinued at an unspecified date.[7] 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.[8] 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.[9]

Further specific information in regards to HHKB Professional can be found here (Japanese only).

Some of the information pertaining to Happy Hacking Keyboard Professional was made available in English on PFU Systems (formerly PFU America) website. It was later removed for an unknown reason:

HHKB Professional JP Series

HHKB Professional JP[10]

The JP layout uses the layout that is known as JIS (short for Japan Industrial Standard). The layout does not follow what Dr. Wada had originally with the Pro series as in specifically to do with the inverted trapezoid layout. However one thing that shares the common similarities with Professional versus Professional JP is the lack of USB hub as featured on Professional 2 series.

JIS layout adds extra keys which are not normally found on the Professional/Professional 2 series. These keys are mainly specific for inputting Japanese characters such as henkan, muhenkan, kana, etc. Along with the Professional JP re-introduces the arrow keys that are not available as a dedicated key on the Professional/Professional 2 series. It also adds extra few keys that are not found on ANSI variant such as right Control key for instance.

The JP layout is available as a 69 keys variant as opposed to the 60 keys variant found on the ANSI variant. Only very few key caps are cross compatible (modifier-wise). Also for the JP layout comes the lack of option for unlegended keys.[11]

The HHKB Professional JP was introduced on November 10, 2008 and is priced at ¥24,990 (Japanese Yen). At the time of the announcement the HHKB Professional JP keycap sets were also spontaneously released with the keyboard as an optional accessory.

HHKB Professional JP Type-S (silenced switches)[12]

The Professional JP Type-S follows the layout found on HHKB Professional JP however with the added silencing on the plunger/slider. Type-S also bears the insignia on the top right of the keyboard along with extra lettering on the model number.

HHKB Professional JP Type-S was introduced on June 15, 2011 in conjunction with the HHKB Professional 2 Type-S.

HHKB Professional HG Series[13]

The HG Series was introduced for a limited time to celebrate 10th anniversary of the Happy Hacking Keyboard series since the introduction in 1996. This series features a distinct machined aluminium frame made to order for the keyboard, a small wooden box containing the tools along with legs for adjusting the height of the keyboard (up to eight height levels as opposed to three), as well as laser engraving with owner's name on the back of the keyboard. In addition to all this, the HHKB Professional HG was also packaged in a distinct box that is very different from the rest of the boxes that were used in HHKB keyboards. All the keyboards featured in this range are all based on HHKB Professional layout, in other words ANSI layout.[14]

The HHKB Professional HG series was introduced October 12, 2006 and was discontinued on July 31, 2007.[15] PFU announced the discontinuation of HHKB Professional HG on July 17, 2007.[16]

HHKB Professional HG

The HG was available with four variants.[17] They were priced around ¥262,500 (Japanese Yen) according to PFU Direct website.[18]

HHKB Professional HG JAPAN

In addition to the Professional HG, there's also the Professional HG JAPAN. The HG JAPAN features a wajima style lacquer resin on the (mostly) PBT keys to produce a distinct colour unique to Professional HG JAPAN along with gold dust sprinkled on top of each and every key. The key that was used as a basis for coating the wajima style lacquer were charcoal coloured key caps.[19][20]

The HHKB Professional HG JAPAN series was made in collaboration with Toru lacquerware workshop and was said that it was "a fusion of traditional craft and IT".

It was priced at ¥525,000 (Japanese Yen) according to PFU Direct website.[21]

HHKB Professional 2 Series

The Professional 2 series entails a USB hub added to the back of the keyboard for plug-and-play of various USB devices whilst retaining the same layout that Dr. Wada inspired. The USB ports for external USB devices are only offered 100mA and comply with USB2.0 as well as USB1.1 specifications.

The HHKB Professional 2 series was introduced on March 16, 2006 with the exception of Type-S which was introduced at a later date in conjunction with HHKB Professional JP Type-S.

HHKB Professional 2[22]

The Professional 2 keyboard goes back to Dr. Wada's keyboard layout, however it adds USB hubs on the back of Happy Hacking Keyboard for added convenience along with EU directive compliance for environmental standards (complies with RoHS).

The HHKB Professional 2 is priced at ¥24,990 and was on sale from March 24, 2006.

HHKB Professional 2 Type-S (silenced switches)[23]

The Professional 2 Type-S keyboard extends the functionality of Professional 2 keyboard by implementing the silencing on the slider/plunger.

HHKB Professional 2 Type-S was introduced on June 15, 2011 in conjunction with the HHKB Professional JP Type-S.

Topre Keycap Set Reference

Most of the Happy Hacking Keyboard Professional series keyboards are compatible with Topre Realforce keycaps with some minor exceptions:

  • Realforce 89/91/106/108 (Model numbers: SA0100KT*) are compatible for most keys except most modifiers.
  • Realforce 87/104 (Model numbers: XF0100KT*) are compatible for most keys except the legends would be different for some modifiers.
  • Happy Hacking Keyboard Professional JP owners may find less suitable modifiers for use from Topre keycap sets.

Esoterica

The two colours that are available with the keyboard by default are white (白) {hiragana: しろ romaji: shiro} and charcoal gray (墨) {hiragana: すみ romaji: sumi}. The charcoal gray variant is often confused as black (黒){hiragana: くろ romaji: kuro} by unfamiliar people. Charcoal gray variants of the keyboard, like their white coloured counterparts both feature black dye-sublimated legends on the keys. Should the charcoal gray variant be actually black, the black dye-sublimated legends on the keys would be rendered invisible.

Unlike the Lite variants of HHKB series where it would clearly describe white and black clearly, the legends printed on those sets of keys are directly in contrast to each other. That is, white keycaps with black legends and black keycaps with white legends.
