This article covers PFU キーボード HHKB Studio キートップセット (墨) 英語配列.

Overview

The PFU HHKB Studio Keycap Set (Sumi) is a genuine replacement keycap set designed exclusively for the HHKB Studio keyboard series. It features an English layout with blank (no-legend) keycaps in a subtle sumi (black/charcoal) color. The keycaps are made from polybutylene terephthalate (PBT), known for its durability and resistance to shine over long use. This set includes 60 keycaps, a keycap puller, and an instruction manual. It offers HHKB enthusiasts a way to customize both the look and feel of their keyboard while maintaining the original tactile switch quality. As an official PFU accessory, it ensures precise fitment and reliable performance.

Connectivity & Compatibility

This keycap set is compatible only with HHKB Studio keyboards. It is not interchangeable with other HHKB Professional series models or any third‑party mechanical keyboards. Installation is a straightforward process using the included keycap puller, but users should follow the manual carefully to avoid scratching the keycaps. The keycaps and switches are separable, allowing easy removal and replacement. Note that compatibility is strictly limited to HHKB Studio; double‑check your keyboard model before purchasing.

Product Info

The set is available through PFU Direct and at around ¥6,600. It was launched alongside the HHKB Studio keyboard in 2024. The blank keycaps are crafted from PBT plastic, offering a textured feel and excellent longevity. As a genuine OEM accessory, it occupies a premium niche within the HHKB ecosystem, appealing to users who value official compatibility and build quality over third‑party alternatives. The package includes 60 keycaps, a puller, and instructions.
