PFU has released a limited-edition model celebrating the 30th anniversary of its popular keyboard, the HHKB (Happy Hacking Keyboard): the "HHKB Professional HYBRID Type-S (30g actuation)." Its biggest highlight is a light 30g key switch, the first in the HHKB series, and it is priced at 39,600 yen. Only 3,000 units will be sold in Japan, with overseas sales to follow in stages from July 2026.

A First 30g Switch, Arriving for the 30th Anniversary

The headline feature of this anniversary model is its 30g key switch, a first for the HHKB. Until now, HHKB keyboards came only with a 45g actuation force. Responding to users who wanted a lighter typing feel, PFU introduced the 30g option for the first time to mark the 30th anniversary.

A 30g actuation force is light enough that keys can be pressed almost by the weight of your fingers alone. It reduces strain during long typing sessions and fast input, making it easier to achieve the light, nimble typing feel often described as a feather touch. Combined with the smooth keystroke that comes from the electrostatic capacitive (non-contact) switch design, the model balances lightness with a pleasant typing experience.

A Red Control Key and Special Bundled Items Exclusive to the Anniversary Model

The design also carries touches unique to the 30th anniversary edition. The Control key, one of the HHKB's signature elements, features a special red keytop with the 30th anniversary logo applied via dye-sublimation printing. It serves as an eye-catching accent that makes the limited model instantly recognizable.

All units use center-printed keytops. While not as thoroughly minimalist as the blank, non-printed keytops popular among HHKB fans, centering the legends gives a tidy appearance. The package also includes a standard Control key in the body color, a keytop puller tool, and a special 30th anniversary sticker. Being able to swap between the red Control key and the standard-color one according to preference adds to its collectible appeal.

Limited to 3,000 Units: Price and Points to Note Before Buying

A total of 3,000 units will be sold in Japan, split into 1,500 with a US (English) layout and 1,500 with a Japanese layout. To help the keyboards reach as many buyers as possible, purchases are limited to one unit per order. The price is 39,600 yen, and overseas sales are scheduled to roll out in stages from July 2026.

The model is based on the HHKB's flagship Professional HYBRID Type-S. It inherits the HYBRID feature, which supports both USB and Bluetooth wireless connections, and the Type-S trait of suppressed typing noise, making it easy to use even in quiet environments. Because the quantity is fixed, those hoping to get one would do well to act early.

Light Touch Is the Appeal, but 30g Is a Matter of Preference

The 30g actuation force is a major draw, but it will not suit everyone. Even among keyboards in general, 30g is on the very light side. People accustomed to the 45g HHKB or to heavier tactile switches, the type that gives a noticeable bump back to the finger, may find keys registering unintentionally just from resting their fingers on the home position.

People who type by striking hard may also feel the impact of bottoming out more directly in their fingers. To make the most of the lightness, it helps to get used to a typing style where you gently rest the weight of your fingers on the keys. Those who already use a 30g keyboard such as the RealForce will adapt easily, while fans of heavier switches may want to weigh how well it matches their own typing style before choosing.

Summary

The HHKB 30th anniversary model, the "HHKB Professional HYBRID Type-S (30g actuation)," is a special edition packed with the series' first 30g switch, a red Control key, a commemorative sticker, and more. With a limited run of 3,000 units in Japan at 39,600 yen, it is a long-awaited keyboard for fans who have wanted a lighter typing feel. Since 30g is a lightness that divides opinion, it is best suited to those who can factor in how it fits their usual typing style while enjoying the sense of ownership that only an anniversary model can offer.
