PFU updates HHKB Professional keymap modification tool to 2.0.0

PFU Corporation published HHKB Professional Keymap Tool version 2.0.0, upgrading the keymap editor used for HHKB Professional HYBRID Type-S, HHKB Professional HYBRID, and HHKB Professional Classic Type-S. The Windows and macOS download entries on the HHKB official site are both labeled Version 2.0.0 and dated March 5, 2026, and the release pairs the tool update with a HYBRID Type-S firmware A0.48 entry on the firmware page.

The downloads and firmware are explicit: the Windows installer is HHKBKeymapTool_200.exe, 4.28 MB, and the macOS image is HHKBkeymapTool_200ma.dmg, 11 MB. The HYBRID Type-S firmware file is HHKB800_FW_A048.hfb, 276 KB, and the firmware A0.48 update history states, “The following key codes have been added and can be assigned in the Keymap Tool. + F13 to F24 keys + Brightness keys (Brightness Up / Brightness Down) + Numeric Keypad (0～9、NumLock) + Shortcut keys. Sleep time setting is now supported.”

The official Windows and macOS update-history tables list identical UI and feature changes in Keymap Tool 2.0.0, including “Added shortcut (simultaneous key press) function,” “Sleep time setting (when idle) for HYBRID Type‑S and HYBRID models,” “Tooltip display,” “Added layer tabs,” “Light/Dark mode switching,” “Added function to check for updates at startup,” and “Ensured compatibility of profile settings between Windows and macOS.” The tool explicitly expands assignable keys to F13 through F24, numeric keypad 0–9 and Num Lock, and screen brightness Up and Down.

Firmware and model requirements are specified in the update tables: HYBRID Type-S requires firmware A0.48 or later to use the new key codes and sleep-time settings, and Classic Type-S requires firmware A8.03 or later. The supplied extracts do not list a specific firmware version requirement for the non-Type-S HYBRID model, an omission noted in the update-history reconciliation and flagged for verification on the official pages.

Greenkeys reported the 2.0.0 update and added community context, explicitly stating, “Implementation of MOD-TAP will not be implemented,” and advising, “Please check the official website for the upgrade procedure.” Greenkeys also placed this release against PFU organizational moves, noting, “In October 2025, HHKB will become an independent HHKB Business Department, and in light of its 30th anniversary, HHKB is expected to have a ‘highlight project’ regarding 2026,” and, “As for HHKB, it will celebrate its 30th anniversary in December 2026.” At a meetup, users discussed key behavior wishes, for example, “After all, for English alignment users, many people would like to use the ⌘ keys on either side of the space bar as ⌘ with a long press and ‘alphanumeric’ and ‘kana’ with a short press.”

Community reactions on Reddit appear alongside the technical update, with hands-on mod notes such as “Lube and silence-x rings make a big difference,” “I even went a step further and replaced the stock domes with BKE Ultra Lights,” and user experience lines including “The first weeks are rough though, you have to unlearn some muscle memory” and “I bought hkkb type s last month and I guess I won’t be buying any other keyboard from now on.” For corporate background, the earlier Classic Type‑S launch and PFU America context remain relevant, including Satoshi Kubo’s Oct. 21, 2025 remark: “Our customers asked for a simple, wired version of our flagship HHKB Professional Hybrid Type‑S model, and—not only did we listen—we delivered,” said Satoshi Kubo, President and CEO, PFU America, Inc.

The HHKB official download and firmware entries dated March 5, 2026 contain the definitive files and version notes; confirm the HYBRID firmware requirement on the official site before updating, since the supplied extracts list HYBRID Type-S and Classic Type-S firmware numbers but leave the non-Type-S HYBRID firmware requirement unspecified.
